On June 15, 2015 CTI BioPharma reported findings from an investigator-sponsored Phase 2 trial in patients with either primary (de novo) acute myeloid leukemia (AML) or AML that has evolved from myelodysplastic syndrome (MDS) (Press release, CTI BioPharma, JUN 14, 2015, View Source;p=RssLanding&cat=news&id=2059047 [SID:1234505424]). Results showed the combination of tosedostat with low dose cytarabine/Ara-C (LDAC) resulted in an overall response rate (ORR) of 54 percent in elderly patients with AML – with 45 percent of patients achieving durable complete responses (CR). These final results were presented by Dr. Giuseppe Visani, Director of Hematology and Stem Cell Transplant Center at AORMN, Pesaro, Italy in a poster session (abstract #P564) during the 20th Congress of the European Hematology Association (EHA) (Free EHA Whitepaper), June 11-14, 2015 in Vienna, Austria.

AML is the most common acute leukemia affecting adults, and its incidence increases with age. AML may develop from the progression of other diseases, such as MDS, which is a blood cancer that also affects the bone marrow and leads to a decrease in circulating red blood cells. Tosedostat is a potential first-in-class selective inhibitor of aminopeptidases, which are required by tumor cells to provide amino acids necessary for growth and tumor cell survival.

"Both the types and length of responses in this trial with tosedostat are very encouraging – particularly given the limited options and poor outcomes historically observed in elderly patients with acute myeloid leukemia, either de novo or secondary after myelodysplastic syndrome," said Dr. Visani. "Importantly, through this study we have also identified potential biomarkers that may help identify high-risk patients in which we are more likely to see these clinically meaningful results – the findings of which are quite compelling and warrant further study."

Findings Presented at EHA (Free EHA Whitepaper)
Final results presented at EHA (Free EHA Whitepaper) show that responding patients had a significant improvement in overall survival based on response rates compared to non-responding patients (p=0.018). In the intent-to-treat population (ITT), the ORR was 54 percent – with CR observed in 45 percent of patients (n=15/33). In the responding patients, the median time for achieving best response was 74 days (range: 22-145 days) and 55 percent (n=10/18) were still in remission after a median follow-up of 319 days. Safety analysis show that tosedostat in combination with LDAC was generally well tolerated. The primary adverse events observed were pneumonitis (12 percent), cardiac (6 percent), brain hemorrhage (3 percent), and asthenia (3 percent).

One of the secondary endpoints was to identify possible biomarkers associated with sensitivity and/or drug resistance. A gene expression profile (GEP) was performed on purified AML cells obtained from 29 patients. Analysis of these patient cells identified a molecular signature associated with clinical response (CR vs. no CR). Based on the differentially expressed genes (n=212), samples were divided according to either CR or no CR. Results showed that these differentially expressed genes were associated with relevant biological functions and pathways – including B-catenin (beta-catenin), TNFA-NFkB, ERB2, inflammatory response, and epithelial-mesenchimal transition – and showed that the achievement of a CR could be efficiently predicted by GEP.

"The results observed with tosedostat in acute myeloid leukemia add to a growing body of data showing the anti-tumor activity of this aminopeptidase inhibitor and the potential of using this approach to treat blood-related cancers," Alan K. Burnett, M.D., Global Lead for Myeloid Diseases at CTI BioPharma. "Based on the clinical data observed to date, we are advancing the development for tosedostat including the potential for a Phase 3 registrational study for primary acute myeloid leukemia or acute myeloid leukemia that evolves from myelodysplastic syndrome."

About the Study Design
The Phase 2 multicenter clinical trial was designed to assess tosedostat (orally once-daily) in combination with intermittent LDAC (twice daily) in 33 elderly patients (median age = 75 years) with either primary AML or secondary AML after MDS. Courses of LDAC were repeated every four weeks for up to eight cycles in the absence of disease progression or unacceptable toxicity. The primary objective was to exceed the upper limit of institutional expected CR rates (P0=10%, P1= 25%, α=0.05, 1-β=80%); secondary objectives include safety and toxicity, stable disease, overall survival, and progression-free survival as well as the identification of a possible biomarker associated with sensitivity and/or disease resistance through global gene expression profiling (GEP, Affymetrix Transciptome Array 2.0).

The poster for Abstract #P564 – "Tosedostat plus low dose cytarabine induces a high rate of responses that can be predicted by genetic profiling in AML: Final results of a Phase II multicenter study" – is available at www.ctibiopharma.com.

About Tosedostat
Tosedostat is an oral aminopeptidase inhibitor that has demonstrated anti-tumor responses in blood-related cancers and solid tumors in Phase 1-2 clinical trials. Tosedostat is currently being evaluated in multiple Phase 2 clinical trials for the treatment of patients with AML or high-risk MDS and are intended to inform the design of a Phase 3 registration study to support potential regulatory approval. Tosedostat is not approved or commercially available.

About Acute Myeloid Leukemia and Myelodysplastic Syndrome
AML is a cancer characterized by the rapid growth of abnormal white blood cells that accumulate in the bone marrow and interfere with the production of normal blood cells. AML is the most common acute leukemia affecting adults, and its incidence increases with age.1 The symptoms of AML are caused by the replacement of normal bone marrow with leukemic cells, which causes a drop in red blood cells, platelets, and normal white blood cells, leading to infections and bleeding. AML progresses rapidly and is typically fatal within weeks or months if left untreated. In 2015, approximately 20,830 new cases of AML are expected to be diagnosed in the United States and an estimated 10,460 are expected to die from the disease.2 While AML may occur at any age, adults at least 60 years of age are more likely than younger people to develop the disease.2 Although a substantial proportion of younger individuals who develop AML can be cured, AML in the elderly typically responds poorly to standard therapy with few complete remissions.

AML may develop from the progression of other diseases, such as MDS. MDS are a group of diverse bone marrow disorders in which the bone marrow does not produce enough healthy blood cells. MDS is often referred to as a "bone marrow failure disorder."

On June 13, 2015 Novartis reported long-term safety and efficacy results from the pivotal Phase III RESPONSE study evaluating Jakavi (ruxolitinib) for the treatment of patients with polycythemia vera (PV) who are resistant to or intolerant of hydroxyurea (Press release, Novartis, JUN 13, 2015, View Source [SID:1234505425]). A preplanned analysis of the study at 18 months demonstrated that 80% of patients with inadequately controlled PV treated with Jakavi experienced a durable response of sustaining hematocrit less than 45% without the use of phlebotomy and reducing spleen size, two key measures of disease control, for at least one year[1]. Findings were presented at the 20th Congress of the European Hematology Association (EHA) (Free EHA Whitepaper) in Vienna, Austria.

"Polycythemia vera can lead to serious complications if inadequately controlled, and these data demonstrate the ability of Jakavi to provide a durable and comprehensive clinical benefit in this patient population," said lead study investigator Jean-Jacques Kiladjian, MD, PhD, Hôpital Saint-Louis et Université Paris Diderot. "There is currently a significant unmet need for patients with polycythemia vera who are unable to tolerate or control their disease on other treatments. For these patients, Jakavi represents a valuable new option as confirmed by results from the long-term Phase III study."

PV is a rare and incurable blood cancer associated with an overproduction of blood cells that can cause serious cardiovascular complications, such as blood clots, stroke and heart attack[3]. Approximately 25% of patients with PV develop resistance (inadequate response) to or intolerance (unacceptable side effects) of hydroxyurea and are considered to have inadequately controlled disease[2]. This is typically defined as hematocrit levels greater than 45%, elevated white blood cell count and/or platelet count, and may be accompanied by debilitating symptoms and/or an enlarged spleen[2],[4],[5].

In the Phase III study, 83% of patients with PV randomized to Jakavi were still receiving treatment at 18 months (median exposure of 111 weeks) compared to 0 patients on the best available treatment arm. Results also show that Jakavi-treated patients who achieved hematocrit control without phlebotomy had an 89% probability of maintaining their response for 18 months from the time of their initial response and all patients who had an initial spleen response maintained their reduction in spleen size. Of the patients on the Jakavi arm at week 32, 90% of patients did not have a phlebotomy between weeks 32 and 80. In addition, patients treated with Jakavi who achieved complete hematologic remission at week 32 had a 69% probability of maintaining their response for at least 18 months from the time of their initial response[1]. A separate analysis of the study at 18 months demonstrated treatment with Jakavi also led to sustained control of white blood cell and platelet levels, important PV hematologic parameters, with the largest reductions for patients with the most elevated values at baseline[6].

"Until the recent European Commission approval of Jakavi for the treatment of adult patients with polycythemia vera, there were limited alternative treatments available for these patients," said Bruno Strigini, President, Novartis Oncology. "These long-term data not only reinforce the robust evidence we have surrounding Jakavi in polycythemia vera, but also our commitment to bringing new and innovative therapies to people with blood cancers."

Overall, Jakavi was well tolerated. In the Jakavi-treatment arm, the rate for Grade 3 or 4 anemia and thrombocytopenia was 0.9 and 2.6 events per 100 patient-year exposure, respectively, and did not increase from the week 48 analysis. The most common non-hematologic adverse events (AEs) in the Jakavi arm were headache, diarrhea, pruritus and fatigue, which were mainly Grade 1 or 2. Treatment discontinuation due to AEs remained low in the Jakavi arm (4.5%)[1].

About the Pivotal Clinical Trial
RESPONSE is a global, randomized, open-label trial conducted at more than 90 trial sites. 222 patients with PV resistant to or intolerant of hydroxyurea were randomized 1:1 to receive either Jakavi (starting dose of 10 mg twice daily) or best available therapy, which was defined as investigator-selected monotherapy or observation only. The Jakavi dose was adjusted as needed throughout the trial. In the Jakavi arm, patients had a PV diagnosis for a median of 8.2 years and had previously received hydroxyurea for a median of approximately three years. Most patients (>80%) had received at least two phlebotomies in the last 24 weeks prior to screening. Patients were classified as intolerant or resistant to hydroxyurea based on the modified European LeukemiaNet (ELN) defined criteria[1].

The primary endpoint of the trial was the proportion of patients whose hematocrit was controlled without phlebotomy eligibility from week 8 through 32 (with no more than one phlebotomy eligibility between randomization and week 8) and whose spleen volume was reduced by 35% or more from baseline as assessed by imaging at week 32. Patients in the trial who were deemed to be eligible for phlebotomy had hematocrit that was greater than 45% and had increased three or more percentage points from the time they entered the trial (e.g., at baseline), or hematocrit greater than 48%. A second, preplanned analysis was performed at 80 weeks (18 months) evaluating durability of primary response, hematocrit control, spleen size reduction, complete hematologic remission and safety. Also at this 80 week data cutoff, a separate analysis evaluating hematologic parameters was assessed by baseline level[1].

About Polycythemia Vera
PV is a rare and incurable blood cancer associated with an overproduction of blood cells in the bone marrow that affects roughly one to three people per 100,000 globally[3],[7]. The disease is driven by the dysregulation of the JAK-STAT pathway[8]. It is typically characterized by elevated hematocrit, the volume percentage of red blood cells in whole blood, which can lead to a thickening of the blood and an increased risk of blood clots, as well as an elevated white blood cell and platelet count[3]. This can cause serious cardiovascular complications, such as stroke and heart attack, resulting in increased morbidity and mortality[9]. Additionally, patients with PV may have an enlarged spleen and symptoms that are frequent and burdensome, with an overall impact on quality of life similar to that seen with myelofibrosis[5],[10].

A common PV treatment includes phlebotomy, a procedure to remove blood from the body to reduce the concentration of red blood cells, which is used to help maintain a hematocrit level below 45%[3],[9]. However, phlebotomy is usually unsuitable as a permanent treatment option due to its inability to control symptoms or effectively manage the overproduction of red blood cells, therefore cytoreductive agents, such as hydroxyurea, may be added[9]. For patients requiring phlebotomy in combination with hydroxyurea, hematocrit may fluctuate and remain at unsafe levels for significant periods of time[11]. Unfortunately, approximately 25% of patients with PV become resistant to or intolerant of hydroxyurea treatment according to ELN criteria, resulting in inadequate disease control and an increased risk of progression[2].

About Jakavi
Jakavi (ruxolitinib) is an oral inhibitor of the JAK 1 and JAK 2 tyrosine kinases. Jakavi is approved by the European Commission for the treatment of adult patients with polycythemia vera (PV) who are resistant to or intolerant of hydroxyurea and for the treatment of disease-related splenomegaly or symptoms in adult patients with primary myelofibrosis (also known as chronic idiopathic myelofibrosis), post-polycythemia vera myelofibrosis or post-essential thrombocythemia myelofibrosis. Jakavi is approved in more than 80 countries for patients with myelofibrosis, including countries in the European Union, Canada, Japan and countries in Asia, Latin and South America. Additional worldwide regulatory filings are underway in myelofibrosis and PV.

Novartis licensed ruxolitinib from Incyte Corporation for development and commercialization outside the United States. Jakavi is marketed in the United States by Incyte Corporation as Jakafi for the treatment of patients with PV who have had an inadequate response to or are intolerant of hydroxyurea and for the treatment of patients with intermediate or high-risk myelofibrosis.

The recommended starting dose of Jakavi in PV is 10 mg given orally twice daily. The recommended starting dose of Jakavi in myelofibrosis is 15 mg twice daily for patients with a platelet count between 100,000 cubic millimeters (mm3) and 200,000 mm3, and 20 mg twice daily for patients with a platelet count of >200,000 mm3. Doses may be titrated based on safety and efficacy. There is limited information to recommend a starting dose for myelofibrosis and PV patients with platelet counts between 50,000/mm3 and <100,000/mm3. The maximum recommended starting dose in these patients is 5 mg twice daily, and patients should be titrated cautiously[12].

Jakavi is a registered trademark of Novartis AG in countries outside the United States. Jakafi is a registered trademark of Incyte Corporation. The safety and efficacy profile of Jakavi has not yet been established outside the approved indications.

Jakavi Important Safety Information for Treatment of Myelofibrosis (MF) and Polycythemia Vera (PV)
Jakavi can cause serious side effects, including a decrease in blood cell count and infections. Complete blood count monitoring is recommended. Dose reduction or interruption may be required in patients with any hepatic impairment or severe renal impairment or in patients developing hematologic adverse reactions such as thrombocytopenia, anemia and neutropenia. Dose reductions are also recommended when Jakavi is co-administered with strong CYP3A4 inhibitors or fluconazole. Use of Jakavi during pregnancy is not recommended, and women should avoid becoming pregnant during Jakavi therapy. Women taking Jakavi should not breast feed. Progressive multifocal leukoencephalopathy (PML) has been reported. Physicians should be alert for neuropsychiatric symptoms suggestive of PML. Hepatitis B viral load (HBV-DNA titer) increases have been reported in patients with chronic HBV infections. Patients with chronic HBV infection should be treated and monitored according to clinical guidelines. Non-melanoma skin cancer (NMSC) has been reported in Jakavi treated patients. Periodic skin examination is recommended. Very common adverse reactions in MF (>10%) include urinary tract infections, anemia, thrombocytopenia, neutropenia, hypercholesterolemia, dizziness, headache, alanine aminotransferase increased, aspartate aminotransferase increased, bruising and weight gain. Common adverse reactions in MF (1 to 10%) include herpes zoster and flatulence. Uncommon adverse reactions in MF include tuberculosis. Very common adverse reactions in PV (>10%) include anemia, thrombocytopenia, hypercholesterolemia, hypertriglyceridemia, dizziness, alanine aminotransferase increased and aspartate aminotransferase increased. Common adverse reactions in PV (1 to 10%) include urinary tract infections, herpes zoster, weight gain, constipation and hypertension.

On June 13, 2015 Celgene, a wholly owned subsidiary of Celgene Corporation reported two analyses of MCL-002 (SPRINT), its multi-center, open-label, phase II randomized trial comparing Revlimid (lenalidomide) with investigators’ choice (IC) in patients with relapsed/refractory mantle cell lymphoma (MCL), were presented at the European Hematology Association (EHA) (Free EHA Whitepaper) annual congress (Press release, Celgene, JUN 13, 2015, View Source [SID:1234505423]).

In the study, 254 patients were randomized 2:1 to receive either REVLIMID (n=170) or single agent cytarabine, rituximab, gemcitabine, fludarabine or chlorambucil (n=84). The primary efficacy endpoint was progression free survival, defined as the time from randomization to disease progression or death due to any cause. Secondary endpoints, including health-related quality of life (QoL) were analyzed in an exploratory manner.

The primary endpoint, median PFS was significantly improved for lenalidomide vs IC (8.7 vs 5.2 months; HR=0.61, P=0.004). A pre-specified exploratory analysis was presented and examined progression-free survival (PFS) in sub-groups based on prior therapies. Results examining the selected IC treatments in the study showed that REVLIMID provided a reduction in the risk of progression or death vs. each IC treatment. Compared with lenalidomide, and taking into account the small number of patients per IC group, the risk reduction in PFS was 22% vs. rituximab (n=27), 56% vs. gemcitabine (n=20), 42% vs. fludarabine (n=18), 43% vs. chlorambucil (n=11), and 8% vs. cytarabine (n=8).

An exploratory subgroup analysis of PFS based on prior treatment-related subgroups showed statistically improved PFS in several subgroups for REVLIMID over IC, including for patients with for less than 3 years from MCL diagnosis, at least 2 prior systemic therapies or relapses, at least 6 months from last therapy, at least 230 days from last rituximab dose, prior refractory disease, no prior stem cell transplant/high-dose therapy, and prior rituximab.

Treatment group was the main effect associated with significantly better PFS by univariate Cox regression analysis (HR=0.619; P=0.004), and was highly significant in the multivariate analysis (HR=0.384; P= < 0.001). Other factors associated with significantly better PFS by both univariate and multivariate analysis were less than 3 prior systemic anti-lymphoma therapies, and at least 230 days from last prior rituximab.

Also presented was a planned secondary study endpoint of the study. Quality of life (QoL) was measured using the EORTC QLQ-C30 at baseline, after cycles 2, 4, 6 and 8, and at treatment discontinuation. EORTC QLQ-C30 included five functional domains, nine symptom scales, and one global health status/QoL scale.

QoL data completion declined from 93% at screening to 51% at treatment discontinuation during the course of the study, and higher non-compliance rates were seen among IC patients. QoL was maintained (no worsening greater than 10 points) with REVLIMID from baseline through last treatment cycle for evaluated primary and secondary QoL domains. Patients treated with REVLIMID reported similar QoL vs. IC single agents across all domain/scale scores and at each follow-up visit.

A trend toward higher rates of clinically meaningful improvement in QoL was observed in REVLIMID-treated patients across most function and symptom domains/scales at one or more follow-up visits. No significant difference in the QoL was observed between the two arms in the primary endpoint of global health status. Statistically significant QoL differences (at least 10%) comparing REVLIMID vs. IC treatment arms were identified for physical function (24% vs. 8%, respectively; P=0.0025) and pain (29% vs. 18%; P=0.0471).

About REVLIMID

In the United States, REVLIMID is approved in combination with dexamethasone for the treatment of patients with multiple myeloma. REVLIMID is also approved in combination with dexamethasone for the treatment of patients with multiple myeloma who have received at least one prior therapy in nearly 70 countries, encompassing Europe, the Americas, the Middle East and Asia, and in combination with dexamethasone for the treatment of patients whose disease has progressed after one therapy in Australia and New Zealand.

REVLIMID is also approved in the United States, Canada, Switzerland, Australia, New Zealand and several Latin American countries, as well as Malaysia and Israel, for transfusion-dependent anemia due to low- or intermediate-1-risk myelodysplastic syndromes (MDS) associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities and in Europe for the treatment of patients with transfusion-dependent anemia due to low- or intermediate-1-risk MDS associated with an isolated deletion 5q cytogenetic abnormality when other therapeutic options are insufficient or inadequate.

In addition, REVLIMID is approved in the United States for the treatment of patients with mantle cell lymphoma (MCL) whose disease has relapsed or progressed after two prior therapies, one of which included bortezomib.

Important Safety Information

WARNING: EMBRYO-FETAL TOXICITY, HEMATOLOGIC TOXICITY, and VENOUS and ARTERIAL THROMBOEMBOLISM

Embryo-Fetal Toxicity

Do not use REVLIMID during pregnancy. Lenalidomide, a thalidomide analogue, caused limb abnormalities in a developmental monkey study. Thalidomide is a known human teratogen that causes severe life-threatening human birth defects. If lenalidomide is used during pregnancy, it may cause birth defects or embryo-fetal death. In females of reproductive potential, obtain 2 negative pregnancy tests before starting REVLIMID treatment. Females of reproductive potential must use 2 forms of contraception or continuously abstain from heterosexual sex during and for 4 weeks after REVLIMID treatment. To avoid embryo-fetal exposure to lenalidomide, REVLIMID is only available through a restricted distribution program, the REVLIMID REMS program (formerly known as the "RevAssist"program).

Information about the REVLIMID REMS program is available at www.celgeneriskmanagement.com or by calling the manufacturer’s toll-free number 1-888-423-5436.

Hematologic Toxicity (Neutropenia and Thrombocytopenia)

REVLIMID can cause significant neutropenia and thrombocytopenia. Eighty percent of patients with del 5q MDS had to have a dose delay/reduction during the major study. Thirty-four percent of patients had to have a second dose delay/reduction. Grade 3 or 4 hematologic toxicity was seen in 80% of patients enrolled in the study. Patients on therapy for del 5q MDS should have their complete blood counts monitored weekly for the first 8 weeks of therapy and at least monthly thereafter. Patients may require dose interruption and/or reduction. Patients may require use of blood product support and/or growth factors.

Venous and Arterial Thromboembolism

REVLIMID has demonstrated a significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE), as well as risk of myocardial infarction and stroke in patients with MM who were treated with REVLIMID and dexamethasone therapy. Monitor for and advise patients about signs and symptoms of thromboembolism. Advise patients to seek immediate medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. Thromboprophylaxis is recommended and the choice of regimen should be based on an assessment of the patient’s underlying risks.

CONTRAINDICATIONS

Pregnancy: REVLIMID can cause fetal harm when administered to a pregnant female and is contraindicated in females who are pregnant. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus

Allergic Reactions: REVLIMID is contraindicated in patients who have demonstrated hypersensitivity (e.g., angioedema, Stevens-Johnson syndrome, toxic epidermal necrolysis) to lenalidomide

WARNINGS AND PRECAUTIONS

Embryo-Fetal Toxicity:

REVLIMID is an analogue of thalidomide, a known human teratogen that causes life-threatening human birth defects or embryo-fetal death. An embryo-fetal development study in monkeys indicates that lenalidomide produced malformations in offspring of female monkeys who received drug during pregnancy, similar to birth defects observed in humans following exposure to thalidomide during pregnancy
Females of Reproductive Potential: Must avoid pregnancy for at least 4 weeks before beginning REVLIMID therapy, during therapy, during dose interruptions and for at least 4 weeks after completing therapy. Must commit either to abstain continuously from heterosexual sexual intercourse or to use two methods of reliable birth control beginning 4 weeks prior to initiating treatment with REVLIMID, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of REVLIMID. Must obtain 2 negative pregnancy tests prior to initiating therapy

Males: Lenalidomide is present in the semen of patients receiving the drug. Males must always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking REVLIMID and for up to 28 days after discontinuing REVLIMID, even if they have undergone a successful vasectomy. Male patients taking REVLIMID must not donate sperm

Blood Donation: Patients must not donate blood during treatment with REVLIMID and for 1 month following discontinuation of the drug because the blood might be given to a pregnant female patient whose fetus must not be exposed to REVLIMID

REVLIMID REMS Program

Because of embryo-fetal risk, REVLIMID is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) the REVLIMID REMS Program (formerly known as the "RevAssist" Program). Prescribers and pharmacies must be certified with the program and patients must sign an agreement form and comply with the requirements. Further information about the REVLIMID REMS program is available at www.celgeneriskmanagement.com or by telephone at 1-888-423-5436

Hematologic Toxicity: REVLIMID can cause significant neutropenia and thrombocytopenia. Monitor patients with neutropenia for signs of infection. Advise patients to observe for bleeding or bruising, especially with use of concomitant medications that may increase risk of bleeding. MM: Patients taking REVLIMID/dex should have their complete blood counts (CBC) assessed every 7 days for the first 2 cycles, on days 1 and 15 of cycle 3, and every 28 days thereafter. MCL: Patients taking REVLIMID for MCL should have their CBCs monitored weekly for the first cycle (28 days), every 2 weeks during cycles 2-4, and then monthly thereafter. Patients may require dose interruption and/or dose reduction. MDS: See Boxed WARNINGS

Venous and Arterial Thromboembolism: Venous thromboembolic events (DVT and PE) and arterial thromboses are increased in patients treated with REVLIMID. A significantly increased risk of DVT (7.4%) and PE (3.7%) occurred in patients with MM after at least one prior therapy, treated with REVLIMID/dex compared to placebo/dex (3.1% and 0.9%) in clinical trials with varying use of anticoagulant therapies. In NDMM study, in which nearly all patients received antithrombotic prophylaxis, DVT (3.6%) and PE (3.8%) were reported in the Rd continuous arm. Myocardial infarction (MI,1.7%) and stroke (CVA,2.3%) are increased in patients with MM after at least 1 prior therapy who were treated with REVLIMID/dex therapy compared with placebo/dex (0.6%, and 0.9%) in clinical trials. In NDMM study, MI (including acute) was reported (2.3%) in the Rd Continuous arm. Frequency of serious adverse reactions of CVA was (0.8%) in the Rd Continuous arm. Patients with known risk factors, including prior thrombosis, may be at greater risk and actions should be taken to try to minimize all modifiable factors (e.g. hyperlipidemia, hypertension, smoking). In controlled clinical trials that did not use concomitant thromboprophylaxis, 21.5% overall thrombotic events occurred in patients with refractory and relapsed MM who were treated with REVLIMID/dex compared to 8.3% thrombosis in the placebo/dex group. Median time to first thrombosis event was 2.8 months. In NDMM study, which nearly all patients received antithrombotic prophylaxis, overall frequency of thrombotic events was 17.4% in combined Rd continuous and Rd18 arms. Median time to first thrombosis event as 4.37 months. Thromboprophylaxis is recommended and regimen is based on patients underlying risks. ESAs and estrogens may further increase the risk of thrombosis and their use should be based on a benefit-risk decision. See Boxed WARNINGS

Increased Mortality in Patients With CLL: In a clinical trial in the first line treatment of patients with CLL, single agent REVLIMID therapy increased the risk of death as compared to single agent chlorambucil. In an interim analysis, there were 34 deaths among 210 patients on the REVLIMID treatment arm compared to 18 deaths among 211 patients in the chlorambucil treatment arm, and hazard ratio for overall survival was 1.92 [95% CI: 1.08-3.41] consistent with a 92% increase in risk of death. Serious adverse cardiovascular reactions, including atrial fibrillation, myocardial infarction, and cardiac failure occurred more frequently in the REVLIMID treatment arm. REVLIMID is not indicated and not recommended for use in CLL outside of controlled clinical trials

Second Primary Malignancies: In clinical trials in patients with MM receiving REVLIMID, an increase of invasive second primary malignancies notably AML and MDS have been observed. The increase of AML and MDS occurred predominantly in NDMM patients receiving REVLIMID in combination with oral melphalan (5.3%) or immediately following high dose intravenous melphalan and ASCT (up to 5.2%). The frequency of AML and MDS cases in the Revlimid/dex arms was observed to be 0.4%. Cases of B-cell malignancies (including Hodgkin’s Lymphomas) were observed in clinical trials where patients received lenalidomide in the post-ASCT setting. Patients who received REVLIMID-containing therapy until disease progression did not show a higher incidence of invasive SPM than patients treated in the fixed duration REVLIMID-containing arms. Monitor patients for the development of second primary malignancies. Take into account both the potential benefit and risk of second primary malignancies when considering treatment with REVLIMID

Hepatotoxicity: Hepatic failure, including fatal cases, has occurred in patients treated with lenalidomide in combination with dex. The mechanism of drug-induced hepatotoxicity is unknown. Pre-existing viral liver disease, elevated baseline liver enzymes, and concomitant medications may be risk factors. Monitor liver enzymes periodically. Stop REVLIMID upon elevation of liver enzymes. After return to baseline values, treatment at a lower dose may be considered

Allergic Reactions: Angioedema and serious dermatologic reactions including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported. These events can be fatal. Patients with a prior history of Grade 4 rash associated with thalidomide treatment should not receive REVLIMID. REVLIMID interruption or discontinuation should be considered for Grade 2-3 skin rash. REVLIMID must be discontinued for angioedema, Grade 4 rash, exfoliative or bullous rash, or if SJS or TEN is suspected and should not be resumed following discontinuation for these reactions. REVLIMID capsules contain lactose. Risk-benefit of REVLIMID treatment should be evaluated in patients with lactose intolerance

Tumor Lysis Syndrome: Fatal instances of tumor lysis syndrome (TLS) have been reported during treatment with lenalidomide. The patients at risk of TLS are those with high tumor burden prior to treatment. These patients should be monitored closely and appropriate precautions taken

Tumor Flare Reaction: Tumor flare reaction (TFR) has occurred during investigational use of lenalidomide for CLL and lymphoma, and is characterized by tender lymph node swelling, low grade fever, pain and rash.

Monitoring and evaluation for TFR is recommended in patients with MCL. Tumor flare may mimic the progression of disease (PD). In patients with Grade 3 or 4 TFR, it is recommended to withhold treatment with lenalidomide until TFR resolves to ≤ Grade 1. In the MCL trial, approximately 10% of subjects experienced TFR; all reports were Grade 1 or 2 in severity. All of the events occurred in cycle 1 and one patient developed TFR again in cycle 11. Lenalidomide may be continued in patients with Grade 1 and 2 TFR without interruption or modification, at the physician’s discretion. Patients with Grade 1 or 2 TFR may also be treated with corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs) and/or narcotic analgesics for management of TFR symptoms. Patients with Grade 3 or 4 TFR may be treated for management of symptoms per the guidance for treatment of Grade 1 and 2 TFR

Impaired Stem Cell Mobilization: A decrease in the number of CD34+ cells collected after treatment ( > 4 cycles) with REVLIMID has been reported. In patients who are autologous stem cell transplant (ASCT) candidates, referral to a transplant center should occur early in treatment to optimize timing of the stem cell collection.

DRUG INTERACTIONS

Periodic monitoring of digoxin plasma levels, in accordance with clinical judgment and based on standard clinical practice in patients receiving this medication, is recommended during administration of REVLIMID. It is not known whether there is an interaction between dex and warfarin. Close monitoring of PT and INR is recommended in MM patients taking concomitant warfarin. Erythropoietic agents, or other agents, that may increase the risk of thrombosis, such as estrogen containing therapies, should be used with caution after making a benefit-risk assessment in patients receiving REVLIMID

USE IN SPECIFIC POPULATIONS

Pregnancy: If pregnancy does occur during treatment, immediately discontinue the drug. Under these conditions, refer patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. Any suspected fetal exposure to REVLIMID must be reported to the FDA via the MedWatch program at 1-800-332-1088 and also to Celgene Corporation at 1-888-423-5436

Nursing Mothers: It is not known whether REVLIMID is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or the drug, taking into account the importance of the drug to the mother

Pediatric Use: Safety and effectiveness in patients below the age of 18 have not been established

Renal Impairment: Since REVLIMID is primarily excreted unchanged by the kidney, adjustments to the starting dose of REVLIMID are recommended to provide appropriate drug exposure in patients with moderate (CLcr 30-60 mL/min) or severe renal impairment (CLcr < 30 mL/min) and in patients on dialysis

On June 12, 2015 ARIAD reported long-term follow up from its pivotal Phase 2 trial of Iclusig (ponatinib), its approved BCR-ABL inhibitor, in heavily pretreated patients with resistant or intolerant chronic myeloid leukemia (CML) or Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) (Press release, Ariad, JUN 12, 2015, View Source;p=RssLanding&cat=news&id=2058920 [SID:1234505422]). The study now shows that with a median follow-up of approximately 3.5 years for chronic phase CML (CP-CML) patients and a median follow-up of approximately 2.9 years in all patients in the trial, Iclusig continues to demonstrate anti-leukemic activity in patients with limited treatment options. Responses have been maintained long-term in CP-CML patients. Eighty-three percent (83%) of CP-CML patients who achieved a major cytogenetic response (MCyR) are estimated to remain in MCyR at three years.

Additionally, 95 percent of CP-CML patients who underwent ponatinib dose reductions maintained their responses (MCyR). Benefit-risk evaluations should guide the decision to initiate and maintain Iclusig therapy, particularly in patients who may be at increased risk for arterial occlusive events (AOE).

"These continued responses in the PACE study, with a minimum follow-up of 3.3 years, in such a heavily pretreated patient population are very encouraging. Eighty-three percent of CP-CML patients who achieved the primary endpoint of major cytogenetic response remain in MCyR at three years," stated Jorge E. Cortes, M.D., Professor and Deputy Chair, Department of Leukemia, The University of Texas MD Anderson Cancer Center. "Careful assessment of the benefit and risk of initiating ponatinib therapy, particularly in patients who may be at increased risk for arterial occlusive events, can help identify patients with refractory Ph+ leukemias who can benefit most from this treatment."

The data were featured today at the 20th Conference of the European Hematology Association (EHA) (Free EHA Whitepaper) in Vienna, Austria.

PACE Trial Update

The efficacy and safety of ponatinib in CML and Ph+ ALL patients resistant or intolerant to dasatinib or nilotinib, or with the T315I mutation, were evaluated in the pivotal Phase 2 PACE trial. A total of 449 patients were treated with ponatinib at a starting dose of 45 mg/day. Ninety-three percent of patients had previously received two or more approved tyrosine kinase inhibitors (TKI), and 55 percent had previously received three or more approved TKIs.

Updated data on CP-CML patients (n=270) from the ongoing trial indicate that with a median follow-up of 42.3 months (data as of February 2, 2015), 114 patients (42%) continue to receive ponatinib.

Additional data in CP-CML patients include:

59% of CP-CML patients achieved MCyR (primary endpoint) at any time.

83% of patients who achieved MCyR are estimated to remain in MCyR at 3 years.

39% of patients achieved a major molecular response (MMR) or better.

By Kaplan-Meier analysis, progression-free survival at 3 years is estimated to be 60%.

Overall survival at 3 years is estimated to be 81%.

23% of CP-CML patients experienced an AOE designated a serious adverse event (SAE), and 28 percent of CP-CML patients experienced any AOE. The median time to onset for AOEs in CP-CML patients was 14.1 (0.3–44.0) months.

4% and 5% of CP-CML patients, respectively experienced a venous thromboembolic SAE or AE.

The most common all-grade treatment-emergent adverse events occurring in ≥ 40% of CP-CML patients were abdominal pain (46%), rash (46%), thrombocytopenia (45%), headache (43%), constipation (41%), and dry skin (41%); the discontinuation rate due to adverse events was 18% in CP-CML.

"These data show that the majority of CP-CML patients in the PACE trial retained their anti-leukemic responses, even when lowering the daily dose of Iclusig," stated Frank G. Haluska, M.D., Ph.D., senior vice president of clinical research and development and chief medical officer at ARIAD. "The safety and efficacy of Iclusig at starting doses lower than 45 mg will be studied in the randomized OPTIC (Optimizing Ponatinib Treatment In CML) trial set to begin shortly."

Efficacy Update Following Prospective Dose-Reduction Recommendations
(Data from October 10, 2013 to February 2, 2015)

On October 10, 2013, dose-reduction recommendations were provided by ARIAD to investigators for patients remaining on the PACE trial. The following dose reductions were recommended, unless the benefit-risk analysis warranted treatment with a higher dose:

CP-CML patients who already achieved a MCyR should have their ponatinib dose reduced to 15 mg/day,
CP-CML patients who had not already achieved MCyR should have their dose reduced to 30 mg/day, and
Advanced-phase patients should have their dose reduced to 30 mg/day.

As of February 2015, with 1.3 years (16 months) of follow-up after these recommendations, the rate of maintenance of response in CP-CML was 95% — whether or not patients underwent prospective dose reductions.

Of the 64 patients who were in MCyR as of October 10, 2013 and had a prospective dose reduction, 61 patients (95%) maintained their response at 1.3 years following prospective dose reduction.

Of the 47 patients who were in MMR as of October 10, 2013 and had a prospective dose reduction, 44 patients (94%) maintained their response at 1.3 years following prospective dose reduction.

42 patients in MCyR did not undergo any dose reductions (the majority of which were already at a reduced dose of 30 mg or 15 mg as of October 10, 2013); of these, 39 patients (93%) maintained MCyR after 1.3 more years of ponatinib treatment.

Safety Update Following Prospective Dose-Reduction

Recommendations (Data from October 10, 2013 to February 2, 2015)

Of the patients who underwent prospective dose reduction, 5 of 71 patients (7%) without prior AOEs had a new AOE during the 1.3 year interval following prospective dose reduction.

Of the patients who did not undergo prospective dose reduction, 9 of 67 patients (13%) without prior AOE had a new AOE in the same time interval.

About Iclusig (ponatinib) tablets

Iclusig is approved in the U.S., EU, Australia, Israel, Canada and Switzerland.

In the U.S., Iclusig is a kinase inhibitor indicated for the:

Treatment of adult patients with T315I-positive chronic myeloid leukemia (chronic phase, accelerated phase, or blast phase) or T315I-positive Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL).

Treatment of adult patients with chronic phase, accelerated phase, or blast phase chronic myeloid leukemia or Ph+ ALL for whom no other tyrosine kinase inhibitor (TKI) therapy is indicated.

These indications are based upon response rate. There are no trials verifying an improvement in disease-related symptoms or increased survival with Iclusig.

IMPORTANT SAFETY INFORMATION, INCLUDING THE BOXED WARNING

WARNING: VASCULAR OCCLUSION, HEART FAILURE, and HEPATOTOXICITY

See full prescribing information for complete boxed warning

Vascular Occlusion: Arterial and venous thrombosis and occlusions have occurred in at least 27% of Iclusig treated patients, including fatal myocardial infarction, stroke, stenosis of large arterial vessels of the brain, severe peripheral vascular disease, and the need for urgent revascularization procedures. Patients with and without cardiovascular risk factors, including patients less than 50 years old, experienced these events. Monitor for evidence of thromboembolism and vascular occlusion. Interrupt or stop Iclusig immediately for vascular occlusion. A benefit risk consideration should guide a decision to restart Iclusig therapy.

Heart Failure, including fatalities, occurred in 8% of Iclusig-treated patients. Monitor cardiac function. Interrupt or stop Iclusig for new or worsening heart failure.

Hepatotoxicity, liver failure and death have occurred in Iclusig-treated patients. Monitor hepatic function. Interrupt Iclusig if hepatotoxicity is suspected.

Vascular Occlusion: Arterial and venous thrombosis and occlusions, including fatal myocardial infarction, stroke, stenosis of large arterial vessels of the brain, severe peripheral vascular disease, and the need for urgent revascularization procedures have occurred in at least 27% of Iclusig-treated patients from the phase 1 and phase 2 trials. Iclusig can also cause recurrent or multi-site vascular occlusion. Overall, 20% of Iclusig-treated patients experienced an arterial occlusion and thrombosis event of any grade. Fatal and life-threatening vascular occlusion has occurred within 2 weeks of starting Iclusig treatment and in patients treated with average daily dose intensities as low as 15 mg per day. The median time to onset of the first vascular occlusion event was 5 months. Patients with and without cardiovascular risk factors have experienced vascular occlusion although these events were more frequent with increasing age and in patients with prior history of ischemia, hypertension, diabetes, or hyperlipidemia. Interrupt or stop Iclusig immediately in patients who develop vascular occlusion events.

Heart Failure: Fatal and serious heart failure or left ventricular dysfunction occurred in 5% of Iclusig-treated patients (22/449). Eight percent of patients (35/449) experienced any grade of heart failure or left ventricular dysfunction. Monitor patients for signs or symptoms consistent with heart failure and treat as clinically indicated, including interruption of Iclusig. Consider discontinuation of Iclusig in patients who develop serious heart failure.

Hepatotoxicity: Iclusig can cause hepatotoxicity, including liver failure and death. Fulminant hepatic failure leading to death occurred in an Iclusig-treated patient within one week of starting Iclusig. Two additional fatal cases of acute liver failure also occurred. The fatal cases occurred in patients with blast phase CML (BP-CML) or Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL). Severe hepatotoxicity occurred in all disease cohorts. Iclusig treatment may result in elevation in ALT, AST, or both. Monitor liver function tests at baseline, then at least monthly or as clinically indicated. Interrupt, reduce or discontinue Iclusig as clinically indicated.

Hypertension: Treatment-emergent hypertension (defined as systolic BP≥140 mm Hg or diastolic BP≥90 mm Hg on at least one occasion) occurred in 67% of patients (300/449). Eight patients treated with Iclusig (2%) experienced treatment-emergent symptomatic hypertension as a serious adverse reaction, including one patient (<1%) with hypertensive crisis. Patients may require urgent clinical intervention for hypertension associated with confusion, headache, chest pain, or shortness of breath. In 131 patients with Stage 1 hypertension at baseline, 61% (80/131) developed Stage 2 hypertension. Monitor and manage blood pressure elevations during Iclusig use and treat hypertension to normalize blood pressure. Interrupt, dose reduce, or stop Iclusig if hypertension is not medically controlled.

Pancreatitis: Clinical pancreatitis occurred in 6% (28/449) of patients (5% Grade 3) treated with Iclusig. Pancreatitis resulted in discontinuation or treatment interruption in 6% of patients (25/449). The incidence of treatment-emergent lipase elevation was 41%. Check serum lipase every 2 weeks for the first 2 months and then monthly thereafter or as clinically indicated. Consider additional serum lipase monitoring in patients with a history of pancreatitis or alcohol abuse. Dose interruption or reduction may be required. In cases where lipase elevations are accompanied by abdominal symptoms, interrupt treatment with Iclusig and evaluate patients for pancreatitis. Do not consider restarting Iclusig until patients have complete resolution of symptoms and lipase levels are less than 1.5 x ULN.

Neuropathy: Peripheral and cranial neuropathy have occurred in Iclusig-treated patients. Overall, 13% (59/449) of Iclusig-treated patients experienced a peripheral neuropathy event of any grade (2%, grade 3/4). In clinical trials, the most common peripheral neuropathies reported were peripheral neuropathy (4%, 18/449), paresthesia (4%, 17/449), hypoesthesia (2%, 11/449), and hyperesthesia (1%, 5/449). Cranial neuropathy developed in 1% (6/449) of Iclusig-treated patients (<1% grade 3/4). Of the patients who developed neuropathy, 31% (20/65) developed neuropathy during the first month of treatment. Monitor patients for symptoms of neuropathy, such as hypoesthesia, hyperesthesia, paresthesia, discomfort, a burning sensation, neuropathic pain or weakness. Consider interrupting Iclusig and evaluate if neuropathy is suspected.

Ocular Toxicity: Serious ocular toxicities leading to blindness or blurred vision have occurred in Iclusig-treated patients. Retinal toxicities including macular edema, retinal vein occlusion, and retinal hemorrhage occurred in 3% of Iclusig-treated patients. Conjunctival or corneal irritation, dry eye, or eye pain occurred in 13% of patients. Visual blurring occurred in 6% of the patients. Other ocular toxicities include cataracts, glaucoma, iritis, iridocyclitis, and ulcerative keratitis. Conduct comprehensive eye exams at baseline and periodically during treatment.

Hemorrhage: Serious bleeding events, including fatalities, occurred in 5% (22/449) of patients treated with Iclusig. Hemorrhagic events occurred in 24% of patients. The incidence of serious bleeding events was higher in patients with accelerated phase CML (AP-CML), BP-CML, and Ph+ ALL. Most hemorrhagic events, but not all occurred in patients with grade 4 thrombocytopenia. Interrupt Iclusig for serious or severe hemorrhage and evaluate.

Fluid Retention: Serious fluid retention events occurred in 3% (13/449) of patients treated with Iclusig. One instance of brain edema was fatal. In total, fluid retention occurred in 23% of the patients. The most common fluid retention events were peripheral edema (16%), pleural effusion (7%), and pericardial effusion (3%). Monitor patients for fluid retention and manage patients as clinically indicated. Interrupt, reduce, or discontinue Iclusig as clinically indicated.

Cardiac Arrhythmias: Symptomatic bradyarrhythmias that led to a requirement for pacemaker implantation occurred in 1% (3/449) of Iclusig-treated patients. Advise patients to report signs and symptoms suggestive of slow heart rate (fainting, dizziness, or chest pain). Supraventricular tachyarrhythmias occurred in 5% (25/449) of Iclusig-treated patients. Atrial fibrillation was the most common supraventricular tachyarrhythmia and occurred in 20 patients. For 13 patients, the event led to hospitalization. Advise patients to report signs and symptoms of rapid heart rate (palpitations, dizziness). Interrupt Iclusig and evaluate.

Myelosuppression: Severe (grade 3 or 4) myelosuppression occurred in 48% (215/449) of patients treated with Iclusig. The incidence of these events was greater in patients with AP-CML, BP-CML and Ph+ ALL than in patients with CP-CML. Obtain complete blood counts every 2 weeks for the first 3 months and then monthly or as clinically indicated, and adjust the dose as recommended.

Tumor Lysis Syndrome: Two patients (<1%) with advanced disease (AP-CML, BP-CML, or Ph+ ALL) treated with Iclusig developed serious tumor lysis syndrome. Hyperuricemia occurred in 7% (30/449) of patients overall; the majority had CP-CML (19 patients). Due to the potential for tumor lysis syndrome in patients with advanced disease, ensure adequate hydration and treat high uric acid levels prior to initiating therapy with Iclusig.

Compromised Wound Healing and Gastrointestinal Perforation: Since Iclusig may compromise wound healing, interrupt Iclusig for at least 1 week prior to major surgery. Serious gastrointestinal perforation (fistula) occurred in one patient 38 days post-cholecystectomy.

Embryo-Fetal Toxicity: Iclusig can cause fetal harm. If Iclusig is used during pregnancy, or if the patient becomes pregnant while taking Iclusig, the patient should be apprised of the potential hazard to the fetus. Advise women to avoid pregnancy while taking Iclusig.

Most common non-hematologic adverse reactions: (≥20%) were hypertension, rash, abdominal pain, fatigue, headache, dry skin, constipation, arthralgia, nausea, and pyrexia. Hematologic adverse reactions included thrombocytopenia, anemia, neutropenia, lymphopenia, and leukopenia.
