FDA Approves Addition Of Positive Overall Survival Data From Phase 3 ASPIRE Trial To KYPROLIS® (carfilzomib) Label

On June 11, 2018 Amgen (NASDAQ:AMGN) reported that the U.S. Food and Drug Administration (FDA) has approved the supplemental New Drug Application (sNDA) to add the positive overall survival (OS) data from the Phase 3 ASPIRE trial to the U.S. Prescribing Information for KYPROLIS (carfilzomib) (Press release, Amgen, JUN 11, 2018, View Source;p=RssLanding&cat=news&id=2354016 [SID1234527261]). Data added to the label showed that KYPROLIS, lenalidomide and dexamethasone (KRd) significantly reduced the risk of death by 21 percent and extended overall survival by 7.9 months versus lenalidomide and dexamethasone alone (Rd) in patients with relapsed or refractory multiple myeloma (median OS 48.3 months for KRd versus 40.4 months for Rd, HR=0.79, 95 percent CI, 0.67 – 0.95; two-sided p=0.0091).

"Amgen is focused on advancing treatment options that have the potential to transform outcomes for patients," said David M. Reese, M.D., senior vice president of Translational Sciences and Oncology at Amgen. "The ASPIRE trial showed significant improvement in survival in patients with relapsed or refractory multiple myeloma who received KYPROLIS as part of a triplet regimen. With this approval, the U.S. Prescribing Information for KYPROLIS now includes positive overall survival data from two Phase 3 trials, underscoring the important role of proteasome inhibition in the treatment of multiple myeloma."

Full OS results from ASPIRE were published earlier this year in the Journal of Clinical Oncology. The safety data were consistent with the known safety profile of KYPROLIS. The most common adverse events (greater than or equal to 20 percent) in the KYPROLIS arm were diarrhea, anemia, neutropenia, fatigue, upper respiratory tract infection, pyrexia, cough, hypokalemia, thrombocytopenia, muscle spasms, pneumonia, nasopharyngitis, nausea, constipation, insomnia and bronchitis.

Since its approval in 2012, approximately 80,000 patients worldwide have received KYPROLIS. The KYPROLIS clinical program continues to focus on providing treatment options for physicians and patients for this frequently relapsing and difficult-to-treat blood cancer.

About ASPIRE

The international, randomized Phase 3 ASPIRE (CArfilzomib, Lenalidomide, and DexamethaSone versus Lenalidomide and Dexamethasone for the treatment of PatIents with Relapsed Multiple MyEloma) trial evaluated KYPROLIS in combination with lenalidomide and dexamethasone, versus lenalidomide and dexamethasone alone, in patients with relapsed or refractory multiple myeloma following treatment with one to three prior regimens. The primary endpoint of the trial was progression-free survival, defined as the time from treatment initiation to disease progression or death. Secondary endpoints included OS, overall response rate, duration of response, disease control rate, health-related quality of life and safety. Patients were randomized to receive KYPROLIS (20 mg/m2 on days 1 and 2 of cycle one, escalating to 27 mg/m2 on days 8, 9, 15 and 16 of cycle one and continuing on days 1, 2, 8, 9, 15 and 16 of subsequent cycles), in addition to a standard dosing schedule of lenalidomide (25 mg per day for 21 days on, seven days off) and low-dose dexamethasone (40 mg per week in four-week cycles), versus lenalidomide and low-dose dexamethasone alone. The study randomized 792 patients at sites in North America, Europe and Israel.

About Multiple Myeloma

Multiple myeloma is an incurable blood cancer, characterized by a recurring pattern of remission and relapse.1 It is a rare and life-threatening disease that accounts for approximately two percent of all cancers.2,3 In the U.S., there are more than 124,000 people living with, or in remission from, multiple myeloma.2 Approximately 30,770 Americans are diagnosed with multiple myeloma each year and 12,770 patient deaths are reported on an annual basis.2

About KYPROLIS (carfilzomib)

Proteasomes play an important role in cell function and growth by breaking down proteins that are damaged or no longer needed.4 KYPROLIS has been shown to block proteasomes, leading to an excessive build-up of proteins within cells.4 In some cells, KYPROLIS can cause cell death, especially in myeloma cells because they are more likely to contain a higher amount of abnormal proteins.4,5

KYPROLIS is approved in the U.S. for the following:

In combination with dexamethasone or with lenalidomide plus dexamethasone for the treatment of patients with relapsed or refractory multiple myeloma who have received one to three lines of therapy.
As a single agent for the treatment of patients with relapsed or refractory multiple myeloma who have received one or more lines of therapy.
KYPROLIS is also approved in Argentina, Australia, Bahrain, Canada, Hong Kong, Israel, Japan, Kuwait, Lebanon, Macao, Mexico, Thailand, Colombia, S. Korea, Qatar, Switzerland, United Arab Emirates, Turkey, Russia, Brazil, India, Oman and the United States. Additional regulatory applications for KYPROLIS are underway and have been submitted to health authorities worldwide.

Important U.S. KYPROLIS (carfilzomib) Safety Information

Cardiac Toxicities

New onset or worsening of pre‐existing cardiac failure (e.g., congestive heart failure, pulmonary edema, decreased ejection fraction), restrictive cardiomyopathy, myocardial ischemia, and myocardial infarction including fatalities have occurred following administration of KYPROLIS. Some events occurred in patients with normal baseline ventricular function. Death due to cardiac arrest has occurred within one day of KYPROLIS administration.
Monitor patients for clinical signs or symptoms of cardiac failure or cardiac ischemia. Evaluate promptly if cardiac toxicity is suspected. Withhold KYPROLIS for Grade 3 or 4 cardiac adverse events until recovery, and consider whether to restart KYPROLIS at 1 dose level reduction based on a benefit/risk assessment.
While adequate hydration is required prior to each dose in Cycle 1, monitor all patients for evidence of volume overload, especially patients at risk for cardiac failure. Adjust total fluid intake as clinically appropriate in patients with baseline cardiac failure or who are at risk for cardiac failure.
Patients ≥ 75 years, the risk of cardiac failure is increased. Patients with New York Heart Association Class III and IV heart failure, recent myocardial infarction, conduction abnormalities, angina, or arrhythmias may be at greater risk for cardiac complications and should have a comprehensive medical assessment (including blood pressure control and fluid management) prior to starting treatment with KYPROLIS and remain under close follow‐up.
Acute Renal Failure

Cases of acute renal failure, including some fatal renal failure events, and renal insufficiency adverse events (including renal failure) have occurred in patients receiving KYPROLIS. Acute renal failure was reported more frequently in patients with advanced relapsed and refractory multiple myeloma who received KYPROLIS monotherapy. Monitor renal function with regular measurement of the serum creatinine and/or estimated creatinine clearance. Reduce or withhold dose as appropriate.
Tumor Lysis Syndrome

Cases of Tumor Lysis Syndrome (TLS), including fatal outcomes, have occurred in patients receiving KYPROLIS. Patients with multiple myeloma and a high tumor burden should be considered at greater risk for TLS. Adequate hydration is required prior to each dose in Cycle 1, and in subsequent cycles as needed. Consider uric acid lowering drugs in patients at risk for TLS. Monitor for evidence of TLS during treatment and manage promptly. Withhold KYPROLIS until TLS is resolved.
Pulmonary Toxicity

Acute Respiratory Distress Syndrome (ARDS), acute respiratory failure, and acute diffuse infiltrative pulmonary disease such as pneumonitis and interstitial lung disease have occurred in patients receiving KYPROLIS. Some events have been fatal. In the event of drug‐induced pulmonary toxicity, discontinue KYPROLIS.
Pulmonary Hypertension

Pulmonary arterial hypertension (PAH) was reported in patients treated with KYPROLIS. Evaluate with cardiac imaging and/or other tests as indicated. Withhold KYPROLIS for PAH until resolved or returned to baseline and consider whether to restart KYPROLIS based on a benefit/risk assessment.
Dyspnea

Dyspnea was reported in patients treated with KYPROLIS. Evaluate dyspnea to exclude cardiopulmonary conditions including cardiac failure and pulmonary syndromes. Stop KYPROLIS for Grade 3 or 4 dyspnea until resolved or returned to baseline. Consider whether to restart KYPROLIS based on a benefit/risk assessment.
Hypertension

Hypertension, including hypertensive crisis and hypertensive emergency, has been observed with KYPROLIS. Some of these events have been fatal. It is recommended to control hypertension prior to starting KYPROLIS. Monitor blood pressure regularly in all patients. If hypertension cannot be adequately controlled, withhold KYPROLIS and evaluate. Consider whether to restart KYPROLIS based on a benefit/risk assessment.
Venous Thrombosis

Venous thromboembolic events (including deep venous thrombosis and pulmonary embolism) have been observed with KYPROLIS. Thromboprophylaxis is recommended for patients being treated with the combination of KYPROLIS with dexamethasone or with lenalidomide plus dexamethasone. The thromboprophylaxis regimen should be based on an assessment of the patient’s underlying risks. Thromboprophylaxis is recommended for patients being treated with the combination of KYPROLIS with dexamethasone or with lenalidomide plus dexamethasone. The thromboprophylaxis regimen should be based on an assessment of the patient’s underlying risks.
Patients using oral contraceptives or a hormonal method of contraception associated with a risk of thrombosis should consider an alternative method of effective contraception during treatment with KYPROLIS in combination with dexamethasone or lenalidomide plus dexamethasone.
Infusion Reactions

Infusion reactions, including life‐threatening reactions, have occurred in patients receiving KYPROLIS. Symptoms include fever, chills, arthralgia, myalgia, facial flushing, facial edema, vomiting, weakness, shortness of breath, hypotension, syncope, chest tightness, or angina. These reactions can occur immediately following or up to 24 hours after administration of KYPROLIS. Premedicate with dexamethasone to reduce the incidence and severity of infusion reactions. Inform patients of the risk and of symptoms of an infusion reaction and to contact a physician immediately if they occur. Premedicate with dexamethasone to reduce the incidence and severity of infusion reactions. Inform patients of the risk and of symptoms of an infusion reaction and to contact a physician immediately if they occur.
Hemorrhage

Fatal or serious cases of hemorrhage have been reported in patients receiving KYPROLIS. Hemorrhagic events have included gastrointestinal, pulmonary, and intracranial hemorrhage and epistaxis. Promptly evaluate signs and symptoms of blood loss. Reduce or withhold dose as appropriate.
Thrombocytopenia

KYPROLIS causes thrombocytopenia with recovery to baseline platelet count usually by the start of the next cycle. Thrombocytopenia was reported in patients receiving KYPROLIS. Monitor platelet counts frequently during treatment with KYPROLIS. Reduce or withhold dose as appropriate.
Hepatic Toxicity and Hepatic Failure

Cases of hepatic failure, including fatal cases, have been reported during treatment with KYPROLIS. KYPROLIS can cause increased serum transaminases. Monitor liver enzymes regularly regardless of baseline values. Reduce or withhold dose as appropriate.
Thrombotic Microangiopathy

Cases of thrombotic microangiopathy, including thrombotic thrombocytopenic purpura/hemolytic uremic syndrome (TTP/HUS), including fatal outcome have occurred in patients receiving KYPROLIS. Monitor for signs and symptoms of TTP/HUS. Discontinue KYPROLIS if diagnosis is suspected. If the diagnosis of TTP/HUS is excluded, KYPROLIS may be restarted. The safety of reinitiating KYPROLIS therapy in patients previously experiencing TTP/HUS is not known.
Posterior Reversible Encephalopathy Syndrome (PRES)

Cases of PRES have occurred in patients receiving KYPROLIS. PRES was formerly known as Reversible Posterior Leukoencephalopathy Syndrome. Consider a neuro‐radiological imaging (MRI) for onset of visual or neurological symptoms. Discontinue KYPROLIS if PRES is suspected and evaluate. The safety of reinitiating KYPROLIS therapy in patients previously experiencing PRES is not known.
Increased Fatal and Serious Toxicities in Combination with Melphalan and Prednisone in Newly Diagnosed Transplant‐ineligible Patients

In a clinical trial of transplant‐ineligible patients with newly diagnosed multiple myeloma comparing KYPROLIS, melphalan, and prednisone (KMP) vs bortezomib, melphalan, and prednisone (VMP), a higher incidence of serious and fatal adverse events was observed in patients in the KMP arm. KYPROLIS in combination with melphalan and prednisone is not indicated for transplant‐ineligible patients with newly diagnosed multiple myeloma.
Embryo‐fetal Toxicity

KYPROLIS can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals.
Females of reproductive potential should be advised to avoid becoming pregnant while being treated with KYPROLIS. Males of reproductive potential should be advised to avoid fathering a child while being treated with KYPROLIS. If this drug is used during pregnancy, or if pregnancy occurs while taking this drug, the patient should be apprised of the potential hazard to the fetus.

Arcus Biosciences Announces FDA Clearance of INDs for AB928 and AB122 and Initiation of Phase 1/1b Program to Evaluate AB928 Combinations

On June 11, 2018 Arcus Biosciences, Inc. (NYSE:RCUS), a clinical-stage biopharmaceutical company focused on creating innovative cancer immunotherapies, reported that the U.S. Food and Drug Administration (FDA) has cleared Investigational New Drug (IND) applications for the Company’s two most advanced product candidates, AB928 and AB122 (Press release, Arcus Biosciences, JUN 11, 2018, View Source [SID1234527262]). Clearance of the first IND for AB928 allows the Company to proceed with its planned Phase 1/1b trial to evaluate the safety, tolerability and preliminary efficacy of AB928 in combination with other agents, including AB122 (the Company’s anti-PD-1 antibody) and chemotherapy, in patients with breast and gynecologic malignancies. Two additional IND applications will be submitted this month which, if cleared, will enable the Company to proceed with trials of AB928 combinations in gastrointestinal malignancies, non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC). In parallel, the Company has been completing the regulatory process to evaluate the combination of AB928 and AB122 in patients in Australia and expects to dose its first patient with this combination shortly.

"We are thrilled to receive our first IND clearances to permit dosing in patients for AB928, our dual adenosine receptor antagonist, in combination with other anti-cancer agents," said Terry Rosen, Ph.D., Chief Executive Officer at Arcus. "For our initial Phase 1/1b combination trials for AB928, we have selected tumor types that we believe will be most responsive to adenosine 2 receptor antagonism and combination partners that we expect to be synergistic with this mechanism, specifically immunogenic cell death (ICD) inducing chemotherapy and anti-PD-1 therapy. We have designed our Phase 1/1b program for AB928 to provide us with significant flexibility to open new arms to evaluate promising combinations and to expand or close existing arms based on the emerging data. We are extremely pleased to begin testing in patients the first adenosine 2 receptor antagonist that was specifically designed to be a therapeutic for cancer."

The Phase 1/1b program for AB928 will initially evaluate AB928 in combination with AB122 and with chemotherapy in three tumor-specific trials. The Phase 1/1b program will begin with a dose-escalation phase to identify the optimal dose of AB928 to be combined with fixed doses of AB122 and with each of the three different ICD-inducing chemotherapy regimens. Once the recommended dose of AB928 for each combination has been selected, the tumor-specific trials will enroll expansion cohorts to evaluate AB928 in combination with AB122 or chemotherapy in the following selected tumor types:

Breast and Gynecologic Malignancies. This trial will initially evaluate AB928 in combination with AB122 and with DOXIL in triple negative breast cancer and ovarian cancer. The FDA has cleared the IND application for this trial.
Gastrointestinal Malignancies. This trial will initially evaluate AB928 in combination with AB122 and with mFOLFOX in gastroesophageal and colorectal cancers. The IND application for this trial will be submitted this month.
Lung Cancer and Renal Cell Carcinoma. This trial will initially evaluate AB928 in combination with AB122 in NSCLC and RCC as well as AB928 in combination with a platinum-based chemotherapy regimen in NSCLC. The trial design will also allow for the exploration of additional AB928 combinations, including triple combinations, and AB928 in combination with other anti-PD-1 antibodies. The IND application for this trial will be submitted this month.
Each trial was designed to allow for the addition of new AB928 combination arms in the future. In the dose-escalation portion of the trials, the Company will assess evidence of immune engagement to enable a mechanistic understanding of early clinical responses and will evaluate the suitability of several potential biomarkers for patient enrichment in the dose-expansion cohorts and in future trials.

Data from the dose-escalation portion of the Phase 1/1b program are expected to be available in the first half of 2019.

About AB928

AB928 is an orally bioavailable, highly potent antagonist of the adenosine 2a and 2b receptors. The activation of these receptors by adenosine interferes with the activity of key populations of immune cells and inhibits an optimal anti-tumor immune response. By blocking these receptors, AB928 has the potential to reverse adenosine-induced immune suppression within the tumor microenvironment. AB928 was designed specifically for the oncology setting, with a profile that includes potent activity in the presence of high concentrations of adenosine and a minimal shift in potency due to non-specific protein binding, both essential properties to be efficacious in the tumor microenvironment. AB928 has other attractive features, including high penetration of tumor tissue and low penetration through the healthy blood-brain barrier. In a Phase 1 trial in healthy volunteers, AB928 has been shown to be safe and well tolerated and to have pharmacokinetic and pharmacodynamic profiles consistent with a once-daily dosing regimen.

Interferons (IFNs) have been successfully applied in various hematological malignancies including PV, Chronic Myeloid Leukemia (CML) and other myeloproliferative neoplasms (MPNs) for about three decades, however no IFN has obtained regulatory approval in these indications yet.

Ropeginterferon alfa-2b is the first monopegylated IFN with an improved application of only once every two weeks (and only once per month in long-term maintenance treatment). The innovative pegylation technology and the molecule have been invented by PharmaEssentia Corporation (Taiwan Stock Exchange: 6446), a long-term partner of AOP Orphan.

In 2009, AOP Orphan has in-licensed from PharmaEssentia Corporation the exclusive rights to develop and commercialize Ropeginterferon alfa-2b in PV, CML and other MPNs for European, Commonwealth of Independent States (CIS), and Middle Eastern markets.

Since 2009, AOP Orphan´s Development Program in PV including the phase I/II trial PEGINVERA and the phase III trials PROUD-PV, PEN-PV and CONTINUATION-PV, have established high efficacy and favorable safety and tolerability of Ropeginterferon alfa-2b in PV. PharmaEssentia Corporation has invested in preparations for commercialization of the drug in its territory and in the capability for commercial manufacturing of the drug. The company´s world-class cGMP biologics facility in Taichung is certified by the Taiwan Food and Drug Administration (TFDA) and since 2018 also by EMA , and it is designed and operated to be compliant with all U.S. FDA requirements.

Commercial availability of Ropeginterferon alfa-2b is expected to fulfill an increasing need of patients and physicians for the long-term management of a yet incurable class of diseases.

bridgebio pharma enters into agreement to acquire late stage therapy for ultra-rare disorder from alexion; launches origin biosciences to develop and commercialize therapy

On June 11, 2018 BridgeBio Pharma reported that it has entered into an agreement with Alexion Pharmaceuticals, Inc. to acquire cyclic pyranopterin monophosphate (cPMP; ALXN1101), a synthetic enzyme co-factor therapy for patients with the ultra-rare disease caused by molybdenum cofactor deficiency (MoCD) Type A (Press release, BridgeBio, JUN 11, 2018, View Source [SID1234576280]). In addition, BridgeBio announced that it was launching a new subsidiary, Origin Biosciences, with sufficient capital to support clinical development of ALXN1101 through potential regulatory approval and commercialization.

MoCD is an ultra-rare autosomal recessive inborn error of metabolism. The disease is caused by a mutation in the MOCS1 gene and leads to defective production of cPMP. Clinical signs of MoCD present shortly after birth and progress rapidly. Newborns with MoCD experience difficulty feeding and intractable seizures yet have no approved available therapies. Patients have a median survival of three years, and those who survive often have severe and irreversible injury to their central nervous system.

"Historically, replacing missing or defective proteins has proven highly efficacious for treating loss of function monogenic conditions – in the case of MoCD type A, we are replacing the missing or defective cPMP, providing children with much needed MoCD activity," said Michael Henderson, M.D., senior vice president of asset acquisition at BridgeBio. "BridgeBio’s team is committed to continuing the development of ALXN1101 for infants born with MoCD Type A deficiency, their families and caregivers."

ALXN1101 is a synthetic version of cPMP, the missing cofactor causing MoCD Type A. In previous work with a recombinant form of cPMP, 11 patients with MoCD Type A had normalization of biomarkers within two days, eight patients showed some suppression of seizures, and three patients had near-normal development. ALXN1101 has received Breakthrough Therapy designation from the US FDA.

"Patients born with MoCD face a bleak future, and we will do all we can to pursue the development of this exciting compound, which has the potential to replace the missing enzyme," said Neil Kumar, Ph.D., CEO of BridgeBio. "BridgeBio aims to sustainably pursue even the rarest of diseases, such as MoCD, especially where we can support drug programs that target well described genetic diseases at their source."

While specific terms of the deal have not been disclosed, BridgeBio has committed sufficient resources to Origin Biosciences to enable clinical development, regulatory approval and to support commercialization of ALXN1101. Alexion will receive additional payments upon the realization of development and sales milestones.
