The 223-patient, double blind, randomized, placebo-controlled trial evaluated the safety of GC4419 and its ability to reduce the duration of radiation-induced severe oral mucositis (SOM) in patients with locally advanced squamous cell head and neck cancer receiving seven weeks of radiation therapy plus cisplatin. Approximately 70 percent of patients receiving chemoradiotherapy develop SOM, as defined by the World Health Organization as Grade 3 or 4, which is the most debilitating side effect of the radiotherapy.

Patients in the trial were treated with either 30 mg or 90 mg of GC4419 or placebo by infusion on the days they received their radiation treatment. Patients were randomized to one of the three treatment groups (1:1:1) and the trial recruited patients in both the United States and Canada. In the trial’s intent-to-treat population, the 90 mg dose of GC4419 met the primary endpoint, demonstrating a statistically significant (p = 0.024) 92 percent reduction in the median duration of SOM from 19 days to 1.5 days.

"Galera is honored ASCO (Free ASCO Whitepaper) has recognized the clinically meaningful results from our Phase 2b trial of GC4419 by selecting the abstract for the Best of ASCO (Free ASCO Whitepaper) program," said Mel Sorensen, M.D., President and CEO of Galera. "This distinction, as well as the receipt of Breakthrough Therapy and Fast Track designations from the U.S. Food and Drug Administration, underscores GC4419’s potential to be an important new treatment for this prevalent toxic effect of radiotherapy. We look forward to working with the FDA to define the next step in the development of GC4419."

Other key highlights from the Phase 2b trial include:

GC4419 exhibited a safety profile comparable to placebo in the two treatment groups, and was well tolerated.
In the 90 mg arm, GC4419 demonstrated a clinically meaningful effect in pre-specified secondary endpoints (incidence and severity of SOM).
GC4419 achieved a 34 percent reduction through completion of radiation (p = 0.009), and a 36 percent reduction through 60 Gy of radiation (p = 0.010), in the overall incidence of SOM.
GC4419 reduced the severity of patients’ OM by 47 percent (p = 0.045).
"Oral mucositis is one of the most common and disruptive side effects experienced by patients undergoing radiation therapy for head and neck cancer, but there are no approved drugs to prevent or treat it," said Carryn Anderson, M.D., trial investigator and Radiation Oncologist, University of Iowa Hospitals and Clinics. "GC4419’s ability to significantly decrease severe oral mucositis while maintaining a favorable safety profile comparable to placebo is an especially encouraging sign of its promise to offer a novel treatment option."

About Oral Mucositis

Oral mucositis (OM) is a painful and problematic complication during cancer treatment, especially radiation therapy, caused by excessive superoxide generated during treatment that breaks down epithelial cells that line the mouth. Patients suffering from OM experience severe pain, inflammation, ulceration and bleeding of the mouth.

In the United States, more than 50 percent of patients with cancer receive radiotherapy at some time in their treatment. In patients with head and neck cancer, radiotherapy is a mainstay of treatment and approximately 70 percent of patients receiving chemoradiotherapy develop severe oral mucositis (SOM) as defined by the World Health Organization as Grade 3 or 4, which is the most debilitating side effect of the radiotherapy.

SOM can adversely affect cancer treatment outcomes by causing interruptions in radiotherapy, which may compromise the otherwise good prognosis for tumor control in many of these patients. SOM may also inhibit patients’ ability to eat solid food or even drink liquids, and can cause serious infections. Further, the costs of managing these side effects are substantial, particularly when hospitalization and/or surgical placement of PEG tubes to maintain nutrition and hydration are required. There is currently no drug approved to prevent or treat SOM in patients with head and neck cancer.

About GC4419

GC4419 is a highly selective and potent small molecule dismutase mimetic that closely mimics the activity of human superoxide dismutase enzymes. GC4419 works to reduce elevated levels of superoxide caused by radiation therapy by rapidly converting superoxide to hydrogen peroxide and oxygen. Left untreated, elevated superoxide can damage noncancerous tissues and lead to debilitating side effects, including oral mucositis (OM), which can limit the anti-tumor efficacy of radiation therapy. Conversion of elevated superoxide to hydrogen peroxide, which is selectively more toxic to cancer cells, can also enhance the effect of radiation on tumors, particularly with stereotactic body radiation therapy (SBRT), which produces high levels of superoxide.

GC4419 has been studied in patients with head and neck cancer, GC4419’s lead indication, for its ability to reduce the duration, incidence and severity of radiation-induced severe oral mucositis (SOM). Results from Galera’s 223-patient, double blind, randomized, placebo-controlled Phase 2b clinical trial demonstrated GC4419’s ability to dramatically reduce the duration of SOM from 19 days to 1.5 days (92 percent), the incidence of SOM through completion of radiation by 34 percent and the severity of patients’ OM by 47 percent, while demonstrating acceptable safety when added to a standard radiotherapy regimen. In addition, in multiple preclinical studies, GC4419 demonstrated an increased tumor response to radiation therapy while preventing toxicity in normal tissue.

The U.S. Food and Drug Administration (FDA) granted Breakthrough Therapy designation to GC4419 for the reduction of the duration, incidence and severity of SOM induced by radiation therapy with or without systemic therapy. The FDA also granted Fast Track designation to GC4419 for the reduction of the severity and incidence of radiation and chemotherapy-induced OM.

On June 3, 2018 Celgene Corporation (NASDAQ:CELG) reported additional results from RELEVANCE, a phase III, randomized, open-label, international clinical study conducted in partnership with the Lymphoma Academic Research Organisation (LYSARC), were presented at the 54th Annual American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Scientific Sessions (ASCO) (Free ASCO Whitepaper) in Chicago, Illinois on June 1-5, 2018 (Press release, Celgene, JUN 3, 2018, View Source [SID1234527064]).

This investigational study evaluated REVLIMID (lenalidomide) plus rituximab (R2), followed by R2 maintenance, an investigational regimen, compared to the standard of care treatment of rituximab plus chemotherapy (R-chemo: R-CHOP, R-bendamustine or R-CVP) followed by rituximab maintenance in patients with previously untreated follicular lymphoma. Investigators found that treatment with a chemotherapy-free R2 regimen offered numerically similar efficacy results for the primary endpoints of progression free survival (PFS) and complete response or unconfirmed complete response (CR/CRu) at 120 weeks with a different safety profile than treatment with the conventional R-chemo standard. As previously disclosed, the study did not achieve the primary endpoints of superior PFS and CR/CRu.

"These findings provide important insight into the efficacy and safety of a chemotherapy-free regimen in patients with previously untreated follicular lymphoma and represent an important step forward in understanding possible treatment options for these patients," said Nathan Fowler, MD, Associate Professor, Department of Lymphoma/Myeloma, University of Texas MD Anderson Cancer Center.

The co-primary efficacy endpoints of the study were CR and CRu at 120 weeks and PFS during the pre-planned analysis (final analysis of CR/CRu and interim analysis of PFS). An analysis of the findings found that 48% of patients in the R2 arm and 53% of those receiving R-chemo maintained CR/Cru 120 weeks after randomization, with a 3-year estimated interim PFS rate of 77% and 78% respectively (P=0.48, HR (95% CI) 1.10 (0.85-1.43)). Preliminary overall survival, one of the study’s secondary endpoints, showed a 3-year survival rate of 94% in both treatment arms. Other secondary endpoints included number of patients with adverse events, time to treatment failure, event-free survival, time to next anti-lymphoma treatment, time to next chemotherapy treatment, overall response rate at 120 weeks based on International Working Group (IWG) 1999 criteria, and health-related quality of life as measured by the EORTC QLQ-C30.

The majority of patients in both arms completed treatment (69% R2 and 71% R-chemo). The most common Grade 3/4 TEAEs in both arms were neutropenia (32% R2 vs. 50% R-chemo), febrile neutropenia (2% R2 vs. 7% R-chemo) and cutaneous events (7% R2 vs. 1% R-chemo). SPMs were reported in 7% R2 and 10% R-chemo patients, and Grade 5 AEs were 1% in both treatment arms.

"We believe the findings of the RELEVANCE trial add further to the understanding of the R2 regimen in patients with follicular lymphoma," said Nadim Ahmed, President of Hematology and Oncology for Celgene. "We now look forward to the results of our AUGMENT study, which is evaluating this important regimen in previously treated patients with indolent lymphomas. These studies support our ongoing efforts to develop a portfolio of novel treatments for lymphoma."

REVLIMID alone or in combination with rituximab is not approved for use in follicular lymphoma in any country.

ABOUT RELEVANCE

RELEVANCE is the first multi-center, international, open-label, randomized phase III clinical trial of the chemotherapy-free combination immunotherapy R2 vs. R-chemo followed by rituximab maintenance in previously untreated, advanced follicular lymphoma patients. The study was conducted by Celgene in the US and Japan and by LYSARC in the rest of the world at 136 centers in 10 countries and evaluated the safety and efficacy of REVLIMID plus rituximab (R2) followed by R2 maintenance compared to the standard of care treatment of rituximab plus chemotherapy (R-CHOP, R-bendamustine or R-CVP) followed by rituximab maintenance.

The trial evaluated 1030 patients with advanced follicular lymphoma who had not received prior treatment and were deemed to require treatment per Groupe d’Etude des Lymphomes Folliculaires (GELF) Criteria. Patients received treatment for 120 weeks and were randomized to receive either R2 or R-chemo treatment. The median age of the patients was 59 years.

The R2 arm received REVLIMID + Rituximab on the following dosing schedules: REVLIMID 20-mg on days 2-22 every 28 days for up to 6 cycles. Patients with a complete response after 6 cycles then received REVLIMID 10-mg on days 2-22 every 28 days for 12 cycles. Patients with a partial response after 6 cycles continued to receive REVLIMID 20 mg for 3-6 cycles until they achieved a CR/CRu, at which time they then received REVLIMID 10 mg on days 2-22 of every 28-day cycle for up to 9 or 6 cycles, respectively. Patients who remained in partial response after the additional 6 cycles received REVLIMID 10 mg for a total of 18 cycles. Rituximab 375 mg/m2 was administered on days 1, 8, 15 and 22 of cycle 1, day 1 of cycles 2 to 6; 8 weeks later responding patients continue with 375 mg/m2 rituximab every 8 weeks for 12 cycles.

The R-chemo arm received ONE of the following: Rituximab – CHOP (72%), Rituximab – CVP (5%), or Rituximab – Bendamustine (23%). Seven to 8 weeks later, responding patients continued with 375 mg/m2 rituximab every 8 weeks for 12 cycles.

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.

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 risk to the fetus

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

WARNINGS AND PRECAUTIONS

Embryo-Fetal Toxicity: See Boxed WARNINGS

Females of Reproductive Potential: See Boxed WARNINGS
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 4 weeks 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 4 weeks 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: See Boxed WARNINGS: Prescribers and pharmacies must be certified with the REVLIMID REMS program by enrolling and complying with the REMS requirements; pharmacies must only dispense to patients who are authorized to receive REVLIMID. Patients must sign a Patient-Physician Agreement Form and comply with REMS requirements; female patients of reproductive potential who are not pregnant must comply with the pregnancy testing and contraception requirements and males must comply with contraception requirements

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 or REVLIMID as maintenance therapy 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. MDS: 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 dose reduction. Please see the Black Box WARNINGS for further information. 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

Venous and Arterial Thromboembolism: See Boxed WARNINGS: Venous thromboembolic events (DVT and PE) and arterial thromboses (MI and CVA) are increased in patients treated with REVLIMID. 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). Thromboprophylaxis is recommended and the regimen should be based on patient’s underlying risks. ESAs and estrogens may further increase the risk of thrombosis and their use should be based on a benefit-risk decision

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. Serious adverse cardiovascular reactions, including atrial fibrillation, myocardial infarction, and cardiac failure, occurred more frequently in the REVLIMID arm. REVLIMID is not indicated and not recommended for use in CLL outside of controlled clinical trials

Second Primary Malignancies (SPM): In clinical trials in patients with MM receiving REVLIMID, an increase of hematologic plus solid tumor SPM, notably AML and MDS, have been observed. Monitor patients for the development of SPM. Take into account both the potential benefit of REVLIMID and risk of SPM when considering treatment

Increased Mortality with Pembrolizumab: In clinical trials in patients with multiple myeloma, the addition of pembrolizumab to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials

Hepatotoxicity: Hepatic failure, including fatal cases, has occurred in patients treated with REVLIMID/dex. 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

Severe Cutaneous Reactions Including Hypersensitivity Reactions: Angioedema and severe cutaneous reactions including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported. DRESS may present with a cutaneous reaction (such as rash, or exfoliative dermatitis), eosinophilia, fever, and/or lymphadenopathy with systemic complications such as hepatitis, nephritis, pneumonitis, myocarditis, and/or pericarditis. 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, TEN, or DRESS is suspected and should not be resumed following discontinuation for these reactions

Tumor Lysis Syndrome (TLS): Fatal instances of 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 (TFR): TFR has occurred during investigational use of lenalidomide for CLL and lymphoma. 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 REVLIMID until TFR resolves to ≤Grade 1. REVLIMID may be continued in patients with Grade 1 and 2 TFR without interruption or modification, at the physician’s discretion

Impaired Stem Cell Mobilization: A decrease in the number of CD34+ cells collected after treatment ( > 4 cycles) with REVLIMID has been reported. Consider early referral to transplant center to optimize timing of the stem cell collection

Thyroid Disorders: Both hypothyroidism and hyperthyroidism have been reported. Measure thyroid function before start of REVLIMID treatment and during therapy

Early Mortality in Patients with MCL: In another MCL study, there was an increase in early deaths (within 20 weeks), 12.9% in the REVLIMID arm versus 7.1% in the control arm. Risk factors for early deaths include high tumor burden, MIPI score at diagnosis, and high WBC at baseline (≥10 x 109/L)

DRUG INTERACTIONS

Periodic monitoring of digoxin plasma levels is recommended due to increased Cmax and AUC with concomitant REVLIMID therapy. Patients taking concomitant therapies such as erythropoietin stimulating agents or estrogen containing therapies may have an increased risk of thrombosis. It is not known whether there is an interaction between dex and warfarin. Close monitoring of PT and INR is recommended in patients with MM taking concomitant warfarin

USE IN SPECIFIC POPULATIONS

PREGNANCY: See Boxed WARNINGS: If pregnancy does occur during treatment, immediately discontinue the drug and refer patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. There is a REVLIMID pregnancy exposure registry that monitors pregnancy outcomes in females exposed to REVLIMID during pregnancy as well as female partners of male patients who are exposed to REVLIMID. This registry is also used to understand the root cause for the pregnancy. Report any suspected fetal exposure to REVLIMID to the FDA via the MedWatch program at 1-800-FDA-1088 and also to Celgene Corporation at 1-888-423-5436
LACTATION: There is no information regarding the presence of lenalidomide in human milk, the effects of REVLIMID on the breastfed infant, or the effects of REVLIMID on milk production. Because many drugs are excreted in human milk and because of the potential for adverse reactions in breastfed infants from REVLIMID, advise female patients not to breastfeed during treatment with REVLIMID
PEDIATRIC USE: Safety and effectiveness have not been established in pediatric patients
RENAL IMPAIRMENT: Adjust the starting dose of REVLIMID based on the creatinine clearance value and in patients on dialysis

On June 3, 2018 Novartis reported positive results from the third Phase III trial of Kisqali (ribociclib) in advanced or metastatic breast cancer. MONALEESA-3 showed Kisqali plus fulvestrant significantly prolonged progression-free survival (PFS) compared to fulvestrant alone in postmenopausal women with hormone-receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) advanced breast cancer (Press release, Novartis, JUN 3, 2018, View Source [SID1234527099]). MONALEESA-3 is the largest phase III trial to evaluate efficacy and safety of a CDK4/6 inhibitor plus fulvestrant in multiple advanced breast cancer patient populations – first-line and second-line settings[1]. These data will be presented today as an oral presentation at the 54th Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) in Chicago (Abstract #1000) and published simultaneously in the Journal of Clinical Oncology.

Kisqali in combination with fulvestrant demonstrated a median PFS of 20.5 months (95% CI: 18.5-23.5 months) compared to 12.8 months (95% CI: 10.9-16.3 months) for fulvestrant alone (HR=0.593; 95% CI: 0.480-0.732; p=.00000041) across both treatment arms. The median PFS for the subgroup of patients receiving Kisqali plus fulvestrant in the first-line setting, including only de novo patients and those whose disease relapsed >12 months since end of neo(adjuvant) endocrine therapy, was not reached compared to 18.3 months for fulvestrant alone (HR=0.577; 95% CI: 0.415-0.802). In patients receiving treatment in the second-line setting, or those who relapsed <12 months since end of neo(adjuvant) endocrine therapy, the median PFS was 14.6 months compared to 9.1 months for fulvestrant alone (HR=0.565; 95% CI: 0.428-0.744)[1].

"The MONALEESA-3 results in patients treated in this first-line setting were particularly significant. Nearly 70% of women who received ribociclib plus fulvestrant in this setting were estimated to remain progression-free at the median follow-up of 16.5 months," said Dennis J. Slamon, MD, Director of Clinical/Translational Research, University of California, Los Angeles Jonsson Comprehensive Cancer Center. "In the advanced breast cancer setting, it is important to ensure we provide patients with treatment options that increase time to disease progression while also maintaining quality of life."

Fifty percent of the women in MONALEESA-3 had lung and/or liver metastases and showed a consistent treatment benefit compared with the overall population. Follow-up to measure overall survival is ongoing as these data remain immature[1].

"MONALEESA-3 data add to the robust body of evidence demonstrating the broad potential of Kisqali to treat pre- and postmenopausal women living with advanced breast cancer in various endocrine combinations and multiple lines of therapy," said Samit Hirawat, MD, Head, Novartis Oncology Global Drug Development. "These results along with the other MONALEESA studies build a compelling case that Kisqali combination therapy should be a cornerstone of first-line treatment of HR+/HER2- advanced breast cancer."

No new safety signals were observed in the MONALEESA-3 trial; adverse events were generally consistent with those observed in MONALEESA-2[1]. The discontinuation rate due to adverse events was 8.5% for Kisqali plus fulvestrant compared to 4.1% for fulvestrant alone[1]. The most common (>=5%) grade 3/4 adverse events in patients receiving Kisqali plus fulvestrant compared to fulvestrant alone were neutropenia (53.4% vs 0%) and leukopenia (14.1% vs 0%)[1].

Additional Kisqali data are being presented at the 2018 ASCO (Free ASCO Whitepaper) Annual Meeting. Further results from MONALEESA-7 showed consistent treatment benefit among premenopausal women with HR+/HER2- advanced breast cancer regardless of prior chemotherapy treatment in the advanced setting (Abstract #1047)[2]. Initial safety data from the CompLEEment-1 trial demonstrated a consistent safety profile for Kisqali in a patient population more reflective of those seen in a real-world setting (Abstract #1056)[3]. Lastly, biomarker data from MONALEESA-2 showed that clinical benefit of Kisqali was consistent across gene expression subgroups with a trend toward greater Kisqali benefit in the high versus low ESR1 expression and low versus high RTK expression subgroups (Abstract #1022)[4].

Novartis is in discussion with the US Food and Drug Administration (FDA) with respect to a supplemental New Drug Application (sNDA), seeking approval of Kisqali plus fulvestrant for the treatment of postmenopausal women with HR+/HER2- advanced breast cancer.

About MONALEESA-3
MONALEESA-3 is a Phase III randomized, double-blind, placebo-controlled study evaluating Kisqali in combination with fulvestrant compared to fulvestrant alone for the treatment of postmenopausal women with HR+/HER2- advanced breast cancer who received no prior or only one line of prior endocrine therapy for advanced disease. A total of 726 people were randomized in the trial, including first-line patients comprised of 367 women who were treatment-naïve and 345 who had received up to one line of prior endocrine therapy for advanced disease. Patients were randomized (2:1) to receive Kisqali plus fulvestrant or fulvestrant alone. Randomization was stratified by the presence or absence of lung or liver metastases and prior endocrine therapy (first-line versus second-line).

About Kisqali (ribociclib)
Kisqali is a selective cyclin-dependent kinase inhibitor, a class of drugs that help slow the progression of cancer by inhibiting two proteins called cyclin-dependent kinase 4 and 6 (CDK4/6). These proteins, when over-activated, can enable cancer cells to grow and divide too quickly. Targeting CDK4/6 with enhanced precision may play a role in ensuring that cancer cells do not continue to replicate uncontrollably.

Kisqali was approved by the US Food and Drug Administration in March 2017 and by the European Commission in August 2017, as initial endocrine-based therapy for postmenopausal women with HR+/HER2- locally advanced or metastatic breast cancer in combination with an aromatase inhibitor based on findings from the pivotal MONALEESA-2 trial. Kisqali is not currently approved for use in combination with fulvestrant or in premenopausal women.

Kisqali is approved for use in 59 countries around the world, including the United States and European Union member states. Kisqali was developed by the Novartis Institutes for BioMedical Research (NIBR) under a research collaboration with Astex Pharmaceuticals.

About the Kisqali Clinical Trial Program
With more than 2,000 patients enrolled in current trials, the MONALEESA program is the largest industry sponsored Phase III clinical program researching a CDK4/6 inhibitor in HR+/HER2- advanced breast cancer. In addition to MONALEESA-3, there are three other Phase III trials evaluating Kisqali combination therapy.

MONALEESA-7 is a Phase III randomized, double-blind, placebo-controlled trial investigating the efficacy and safety of Kisqali in combination with tamoxifen or a non-steroidal aromatase inhibitor plus goserelin versus tamoxifen or an aromatase inhibitor plus goserelin, in premenopausal or perimenopausal women with HR+/HER2- advanced breast cancer who had not previously received endocrine therapy for advanced disease.

MONALEESA-2 is a Phase III global registration trial evaluating Kisqali in combination with letrozole compared to letrozole alone in postmenopausal women with HR+/HER2- advanced breast cancer who received no prior therapy for their advanced breast cancer.

CompLEEment-1 is an open-label, multicenter, Phase IIIb study evaluating the safety and efficacy of Kisqali plus letrozole in pre- or postmenopausal women and men with HR+/HER2- advanced breast cancer who have not received prior hormonal therapy for advanced disease.

More information about these studies can be found at www.ClinicalTrials.gov.

Important Safety Information from the Kisqali EU SmPC
The most common ADRs and the most common grade 3/4 ADRs (reported at a frequency >=20% and >=2% respectively) for which the frequency for Kisqali plus letrozole exceeds the frequency for placebo plus letrozole were blood and lymphatic system disorders (including abnormally low neutrophil and white blood cell count), headache, back pain, nausea, fatigue, diarrhea, vomiting, constipation, hair loss and rash and abnormally low levels of neutrophils or white blood cells, abnormal liver function tests (increased alanine and aspartate aminotransferase), abnormally low lymphocyte count, low levels of phosphate, vomiting, nausea, fatigue and back pain, respectively. Low levels of neutrophils was the most commonly seen severe adverse event; fever in addition to a low neutrophil count was reported in 1.5% of patients.

Kisqali can cause serious side effects such as a significant decrease in neutrophil count, abnormal liver function tests and may have an effect on the electrical activity of the heart known as QT/QTc interval prolongation, which could lead to disturbances in heart rhythm. As a precaution, patients should have complete blood counts, liver function, and serum electrolyte levels measured prior to starting treatment as well as during treatment with Kisqali. Patients should also have their heart activity checked before and monitored during treatment.

The efficacy and safety of ribociclib have not been studied in patients with critical visceral disease.

The use of Kisqali with medicinal products known to prolong QTc interval or strong CYP3A4 inhibitors should be avoided as this may lead to prolongation of the QT/QTc interval. If treatment with a strong CYP3A4 inhibitor cannot be avoided, the Kisqali dose should be reduced. Concomitant administration with other medicines that could affect cardiac repolarization or prolong the QT/QTc interval should be taken into account prior to and during treatment with Kisqali. Patients taking sensitive CYP3A4 substrates with narrow therapeutic index should use caution because of the increased risk of adverse events that may occur if these medications are co-administered with Kisqali.

Kisqali contains soya lecithin and therefore it should not be taken by patients who are allergic to peanut or soya.

Animal studies suggest that Kisqali may cause fetal harm in pregnant women. Therefore, as a precaution, women of childbearing potential should use effective contraception while receiving Kisqali during treatment and up to 21 days after stopping treatment. Women should not breast feed for at least 21 days after the last dose of Kisqali. Kisqali may affect fertility in males.

ASCO 2018: Genosco/Yuhan Announce Results from Phase 1/2 Study of Lazertinib (YH25448, GNS-1480), a 3rd-Generation EGFR-TKI, in Advanced NSCLC

Tweet this
Results from the open-label, multi-center dose-escalation, Phase 1/2 study of lazertinib (YH25448, GNS-1480) for patients with advanced EGFR-TKI-resistant NSCLC with or without CNS metastasis concluded that lazertinib was well-tolerated with low rates of Grade 3 or higher adverse events (AE) and exhibited robust activity in patients with NSCLC with acquired resistance to EGFR-TKIs, with or without brain metastasis. Principal Investigator Byoung Chul Cho, M.D., Ph.D., Division of Medical Oncology, Department of Internal Medicine, Yonsei Cancer Center, Yonsei University College of Medicine, Seoul, Republic of Korea presented the data in a poster session (Abstract 9033).

"These data are impressive and underscore the potential of lazertinib (YH25448, GNS-1480) to be the best-in-class 3rd-generation EGFR-TKI for patients with advanced EGFR T790M mutant NSCLC, including brain metastasis. And importantly, the treatment was well-tolerated with no dose-limiting toxic effects," said Dr. Byoung Chul Cho. "Results indicate that lazertinib compares favorably with results from a similar Phase 1/2 clinical trial of osimertinib (AURA)1, a currently marketed 3rd generation EGFR-TKI."

"The efficacy signals and safety profiles are highly encouraging and validate lazertinib (YH25448, GNS-1480) as a promising 3rd-generation EGFR-TKI inhibitor for patients with limited options," said Jong Sung (John) Koh, Ph.D., Genosco CEO. "Yuhan and Genosco initiated a global Phase 2 trial evaluating lazertinib for patients with NSCLC and anticipate a global Phase 3 trial in 2019."

"These results confirm our belief that recently presented pre-clinical data at AACR (Free AACR Whitepaper)2 may translate into human studies," said Ho-Juhn Song, Ph.D., Director of Biology and Strategic Alliance of Genosco. "The comparative analyses of lazertinib and osimertinib concluded that lazertinib showed greater potency and selectivity, excellent intracranial penetration, superior in vivo efficacy in both single (del19, L858R) and double (L858R/T790M) mutant xenograft models and superior in vivo efficacy in a brain metastasis model."

Study results:

A total of 118 patients [dose-escalation cohort (n=38) and expansion cohort (n=80)] with EGFRm advanced NSCLC with acquired resistance to EGFR-TKIs with or without brain metastasis were enrolled in the Phase 1/2 study as of April 20, 2018.

The results demonstrate that lazertinib (YH25448, GNS-1480) has a good safety profile and was generally well-tolerated. No dose-limiting toxicities were observed up to lazertinib 320mg and there were no dose-dependent increases in treatment-emergent adverse events (TEAEs). Of the evaluable patients (n=110) with a confirmed response at the date of data cutoff, lazertinib (YH25448, GNS-1480) demonstrated promising anti-tumor efficacy signals with a confirmed objective response rate (ORR) of 61% across all dose levels. Of note, the confirmed ORR in patients with T790M+ was 86% at the lazertinib 240mg dose level and in patients with brain metastasis, the intracranial ORR was 55% across all dose levels.

About Lazertinib

Lazertinib (YH25448, GNS-1480) is an oral, potent, highly mutant-selective and irreversible, investigational 3rd-generation EGFR-TKI that penetrates the blood-brain barrier (BBB). It targets the activating EGFR mutations Del19 and L858R, as well as the T790M mutation, while sparing wild type. EGFR mutations are present in approximately 10-15% of NSCLCs. Lazertinib is being evaluated in advanced NSCLC as both first- and second-line treatments.

On June 3, 2018 AbbVie (NYSE: ABBV), a research-based global biopharmaceutical company, reported positive data from the Phase 2 CAPTIVATE (PCYC-1142) study evaluating IMBRUVICA (ibrutinib) in combination with VENCLEXTA (venetoclax) in previously-untreated chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) patients (Press release, AbbVie, JUN 3, 2018, View Source [SID1234527050]). Early results of the combination oral regimen suggest promising activity in treatment-naïve CLL/SLL with 77 percent of the first 30 patients achieving responses with no detectable minimal residual disease (MRD) after six cycles of the combination therapy. MRD is determined by measuring the number of cancer cells remaining and helps confirm depth of remission. The first 14 CLL/SLL patients to complete the clinical trial combination therapy of 12 cycles (15 cycles of ibrutinib) achieved responses with no detectable MRD in approximately nine out of 10 patients, with 93 percent achieving MRD negativity when measuring in peripheral blood and 86 percent with MRD negativity when measuring in the bone marrow.1

These data will be presented today as an oral presentation at the 54th Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) in Chicago (abstract #7502).1 The results were also selected for the 2018 Best of ASCO (Free ASCO Whitepaper) Meetings. IMBRUVICA is a first-in-class Bruton’s tyrosine kinase (BTK) inhibitor jointly developed and commercialized by Pharmacyclics LLC, an AbbVie company, and Janssen Biotech, Inc.

"The findings underscore prior data sets that have been reported by external investigators and support the potential benefit of combining these two agents with complementary mechanisms of action, IMBRUVICA and venetoclax, which may work together to deliver deep responses in chronic lymphocytic leukemia," said Danelle James, M.D., M.A.S., Head of Clinical Science, Pharmacyclics LLC, an AbbVie company. "The Phase 2 results from the CAPTIVATE study suggest we could be one step closer to advancing treatment without the use of chemotherapy for patients with CLL and SLL."

CLL is the most common form of leukemia in adults and is a type of cancer that can develop from cells in the bone marrow that later mature into certain white blood cells (called lymphocytes). These cancer cells start in the bone marrow and later spread to the blood. The prevalence of CLL is approximately 115,000 patients in the U.S. with approximately 19,000 newly diagnosed patients every year.2,3 SLL is a slow-growing lymphoma biologically similar to CLL in which too many immature white blood cells cause lymph nodes to become larger than normal.4 CLL/SLL are predominantly diseases of the elderly, with an average age of 70 at diagnosis.3 Treatment options for CLL vary greatly, depending on the person’s age, the disease risk group, and symptoms. Many people live a long time with CLL, but in general it is very difficult to cure, and early treatment hasn’t been shown to help people live longer.5

"IMBRUVICA demonstrates the progress made in evaluating non-chemotherapy treatments for CLL and the potential for improved outcomes," said William G. Wierda, M.D., Ph.D., D.B. Lane Cancer Research Distinguished Professor, Department of Leukemia, Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center, Houston, TX, and lead investigator of the
CAPTIVATE study.* "We are now working with IMBRUVICA on treatments directed at potentially achieving deep remission with undetectable minimal residual disease and anticipate long treatment-free remissions. Early results from the CAPTIVATE study suggest that IMBRUVICA, when used in combination with venetoclax, may be able drive this much-desired outcome – deep undetectable MRD remission."

Abstract #7502: Phase 2 CAPTIVATE results of ibrutinib (ibr) plus venetoclax (ven) in first-line chronic lymphocytic leukemia (CLL)
Oral presentation: Sunday, June 3 at 10:09 – 10:21 a.m. CDT

In the Phase 2 CAPTIVATE (PCYC-1142) study, treatment-naïve CLL/SLL patients received single-agent ibrutinib (420 mg/day) alone for three 28-day cycles before initiating venetoclax ramp-up (standard ramp-up to 400 mg/day). Early data suggest promising activity for the combination oral regimen with undetectable MRD achieved in 77% of the first 30 patients after six cycles of therapy and undetectable MRD in 86% of the first 14 patients after 12 cycles of therapy in both the bone marrow and blood.

CAPTIVATE is a multicenter study that has enrolled 164 treatment-naïve CLL/SLL patients as defined by the International Workshop on Chronic Lymphocytic Leukemia criteria (median age: 58); 15% had del17p, 18% had del11q, and 32% had longest lymph node diameter (LDi) of 5 or more centimeters (cm). The trial was designed to evaluate if remission with undetectable MRD can provide treatment-naïve CLL/SLL patients with treatment holidays (a period of time when a patient is able to stop therapy).

The first 30 patients enrolled for safety run-in completed six or more cycles of ibrutinib and venetoclax (median treatment duration: 10.4 months ibrutinib, 7.6 months venetoclax). In the safety run-in of the first 14 patients who completed 12 cycles of ibrutinib and venetoclax, no dose-limiting toxicities occurred, with an overall response rate of 100% in the 11 patients assessed (6 complete responses, 5 partial responses). Bone marrow was MRD-negative in 12 of 14 assessed patients after 12 cycles of ibrutinib and venetoclax.

The most common AEs (occurring in ≥ 20% patients) were diarrhea (63%), fatigue (27%), nausea (35%), headache (24%), upper respiratory tract infection (24%) and arthralgia (29%). Grade 3 or higher AEs (occurring in ≥ 3% patients) were neutropenia (27%), hypertension (6%), diarrhea (4%) and thrombocytopenia (6%). No clinical tumor lysis syndrome (TLS) occurred and lab TLS was seen in 1 of 164 patients. In treated patients with baseline LDi 5 cm or greater, LDi decreased to less than 5 cm in 43 of 53 patients (81%) after ibrutinib lead-in. TLS risk shifted from high to medium/low in 36 of 40 patients (90%), and overall, the proportion of high-risk TLS decreased from 24% at baseline to 3% after ibrutinib lead-in.

About IMBRUVICA
IMBRUVICA (ibrutinib) is a first-in-class, oral, once-daily therapy that mainly works by blocking a protein called Bruton’s tyrosine kinase (BTK). BTK is a key signaling molecule in the B-cell receptor signaling complex that plays an important role in the survival and spread of malignant B cells as well as other serious, debilitating conditions.6 IMBRUVICA blocks signals that tell malignant B cells to multiply and spread uncontrollably.

IMBRUVICA is FDA-approved in six distinct patient populations: chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Waldenström’s macroglobulinemia (WM), along with previously-treated mantle cell lymphoma (MCL), previously-treated marginal zone lymphoma (MZL) and previously-treated chronic graft-versus-host disease (cGVHD).7

IMBRUVICA was first approved for adult patients with MCL who have received at least one prior therapy in November 2013.
Soon after, IMBRUVICA was initially approved in adult CLL patients who have received at least one prior therapy in February 2014. By July 2014, the therapy received approval for adult CLL patients with 17p deletion, and by March 2016, the therapy was approved as a frontline CLL treatment.
IMBRUVICA was approved for adult patients with WM in January 2015.
In May 2016, IMBRUVICA was approved in combination with bendamustine and rituximab (BR) for adult patients with previously treated CLL/SLL.
In January 2017, IMBRUVICA was approved for adult patients with MZL who require systemic therapy and have received at least one prior anti-CD20-based therapy.
In August 2017, IMBRUVICA was approved for adult patients with cGVHD that failed to respond to one or more lines of systemic therapy.
Accelerated approval was granted for the MCL and MZL indications based on overall response rate. Continued approval for MCL and MZL may be contingent upon verification and description of clinical benefit in confirmatory trials.

IMBRUVICA has been granted four Breakthrough Therapy Designations from the U.S. FDA. This designation is intended to expedite the development and review of a potential new drug for serious or life-threatening diseases.8 IMBRUVICA was one of the first medicines to receive FDA approval via the new Breakthrough Therapy Designation pathway.

IMBRUVICA is being studied alone and in combination with other treatments in several blood and solid tumor cancers and other serious illnesses. IMBRUVICA has one of the most robust clinical oncology development programs for a single molecule in the industry, with more than 130 ongoing clinical trials. There are approximately 30 ongoing company-sponsored trials, 14 of which are in Phase 3, and more than 100 investigator-sponsored trials and external collaborations that are active around the world. To date, 100,000 patients around the world have been treated with IMBRUVICA in clinical practice and clinical trials.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Hemorrhage: Fatal bleeding events have occurred in patients treated with IMBRUVICA. Grade 3 or higher bleeding events (intracranial hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria, and post-procedural hemorrhage) have occurred in up to 6% of patients. Bleeding events of any grade, including bruising and petechiae, occurred in approximately half of patients treated with IMBRUVICA. The mechanism for the bleeding events is not well understood.

IMBRUVICA may increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies and patients should be monitored for signs of bleeding.

Consider the benefit-risk of withholding IMBRUVICA for at least 3 to 7 days pre and post-surgery depending upon the type of surgery and the risk of bleeding.

Infections: Fatal and non-fatal infections (including bacterial, viral, or fungal) have occurred with IMBRUVICA therapy. Grade 3 or greater infections occurred in 14% to 29% of patients. Cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with IMBRUVICA. Consider prophylaxis according to standard of care in patients who are at increased risk for opportunistic infections.

Monitor and evaluate patients for fever and infections and treat appropriately.

Cytopenias: Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (range, 13 to 29%), thrombocytopenia (range, 5 to 17%), and anemia (range, 0 to 13%) based on laboratory measurements occurred in patients with B-cell malignancies treated with single agent IMBRUVICA.

Monitor complete blood counts monthly.

Cardiac Arrhythmias: Fatal and serious cardiac arrhythmias have occurred with IMBRUVICA therapy. Grade 3 or greater ventricular tachyarrhythmias occurred in 0 to 1% of patients, and Grade 3 or greater atrial fibrillation and atrial flutter occurred in 0 to 6% of patients. These events have occurred particularly in patients with cardiac risk factors, hypertension, acute infections, and a previous history of cardiac arrhythmias.

Periodically monitor patients clinically for cardiac arrhythmias. Obtain an ECG for patients who develop arrhythmic symptoms (e.g., palpitations, lightheadedness, syncope, chest pain) or new onset dyspnea. Manage cardiac arrhythmias appropriately, and if it persists, consider the risks and benefits of IMBRUVICA treatment and follow dose modification guidelines.

Hypertension: Hypertension (range, 6 to 17%) has occurred in patients treated with IMBRUVICA with a median time to onset of 4.6 months (range, 0.03 to 22 months). Monitor patients for new onset hypertension or hypertension that is not adequately controlled after starting IMBRUVICA.

Adjust existing anti-hypertensive medications and/or initiate anti-hypertensive treatment as appropriate.

Second Primary Malignancies: Other malignancies (range, 3 to 16%) including non-skin carcinomas (range, 1 to 4%) have occurred in patients treated with IMBRUVICA. The most frequent second primary malignancy was non-melanoma skin cancer (range, 2 to 13%).

Tumor Lysis Syndrome: Tumor lysis syndrome has been infrequently reported with IMBRUVICA therapy. Assess the baseline risk (e.g., high tumor burden) and take appropriate precautions.

Monitor patients closely and treat as appropriate.

Embryo-Fetal Toxicity: Based on findings in animals, IMBRUVICA can cause fetal harm when administered to a pregnant woman. Advise women to avoid becoming pregnant while taking IMBRUVICA and for 1 month after cessation of therapy. 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 a fetus. Advise men to avoid fathering a child during the same time period.

ADVERSE REACTIONS

B-cell malignancies: The most common adverse reactions (≥20%) in patients with B-cell malignancies (MCL, CLL/SLL, WM and MZL) were thrombocytopenia (62%)*, neutropenia (61%)*, diarrhea (43%), anemia (41%)*, musculoskeletal pain (30%), bruising (30%), rash (30%), fatigue (29%), nausea (29%), hemorrhage (22%), and pyrexia (21%).

Twenty-four percent of patients receiving IMBRUVICA in the cGVHD trial discontinued treatment due to adverse reactions. Adverse reactions leading to dose reduction occurred in 26% of patients.

*Treatment-emergent decreases (all grades) were based on laboratory measurements and adverse reactions.

DRUG INTERACTIONS

CYP3A Inhibitors: Dose adjustment may be recommended.

CYP3A Inducers: Avoid coadministration with strong CYP3A inducers.

SPECIFIC POPULATIONS
Hepatic Impairment (based on Child-Pugh criteria): Avoid use of IMBRUVICA in patients with severe baseline hepatic impairment. In patients with mild or moderate impairment, reduce IMBRUVICA dose.
