ABRAXANE® Demonstrates Significant Improvement in Progression-Free Survival Compared to Standard Chemotherapy in Advanced Melanoma Patients

Society for Melanoma Research Abstracts Published Online in Organization’s Journal

BOUDRY, Switzerland--(BUSINESS WIRE)-- Celgene International Sàrl, a subsidiary of Celgene Corporation (NASDAQ: CELG) today announced that abstracts for the upcoming Society for Melanoma Research meeting have been published online in the organization’s official journal at http://onlinelibrary.wiley.com/doi/10.1111/pcmr.12023/abstract. The publication includes an abstract reviewing results from a phase III metastatic melanoma study with ABRAXANE® (paclitaxel protein-bound particles for injectable suspension) (albumin-bound).

In the randomized, open-label, international study (CA033), ABRAXANE showed a statistically significant improvement in progression-free survival (PFS) in chemotherapy-naïve patients with metastatic melanoma compared to patients receiving dacarbazine chemotherapy (4.8 vs. 2.5 months, respectively (HR:0.792; 95.1% CI: 0.631, 0.992; P=0.044)). An interim analysis of overall survival, the secondary endpoint, shows a trend in favor of the ABRAXANE arm compared to treatment with dacarbazine (12.8 and 10.7 months, respectively (HR:0.831; 99.9% CI: 0.578, 1.196; P=0.094)).

“Metastatic melanoma presents significant treatment challenges due in part to limited therapies, low survival rates at diagnosis and no advances in chemotherapy in thirty-seven years,” said Dr. Evan M. Hersh, lead principal investigator and Professor of Medicine at the University of Arizona College of Medicine and Arizona Cancer Center, Tucson, AZ. “Despite advances with targeted treatment and immunotherapies, there is still a need for new agents including chemotherapy treatments for patients with metastatic melanoma.”

The safety profile of ABRAXANE observed in the CA033 study is comparable with other ABRAXANE pivotal clinical trials. The most common grade ≥3 treatment-related adverse events reported in ≥10% patients were neuropathy (ABRAXANE: 25% vs. dacarbazine: 0%), neutropenia (ABRAXANE: 20% vs. dacarbazine: 10%). The median time to neuropathy improvement with ABRAXANE was 28 days.

These results will be presented at the Society for Melanoma Research 2012 Congress on Sunday, November 11th, in Hollywood, CA.

Future regulatory and clinical strategies are being reviewed in light of these results.

These results are from an investigational study. ABRAXANE is not approved for the treatment of metastatic melanoma.

About the Study

CA033 is a phase III randomized, open-label, international study that evaluated the safety and efficacy of ABRAXANE versus standard chemotherapy, dacarbazine in chemotherapy-naïve patients with stage IV metastatic melanoma. The majority of the patients were males (66%), had an ECOG status of 0 (71%), and had very advanced metastatic disease (M1c stage: 65%). Dacarbazine is the only chemotherapy approved since 1975 by the U.S. Food and Drug Administration for metastatic melanoma.

In the CA033 study, 529 chemotherapy-naïve patients were randomized to receive either ABRAXANE (150mg/m2 weekly for 3 out of 4 weeks) (n=264) or standard chemotherapy, dacarbazine (1000 mg/m2 every three weeks) (n=265). The primary endpoint was progression-free survival (PFS) based on blinded assessment of CT scans obtained every 8 weeks, evaluated per RECIST. The secondary endpoint was OS and other endpoints included objective response rate (ORR), disease control rate (DCR), and safety/tolerability.

About ABRAXANE®

ABRAXANE is an albumin-bound form of paclitaxel that is manufactured using patented nab® technology. ABRAXANE is formulated with albumin, a human protein, and is free of solvents.

In the United States, ABRAXANE was first approved in January 2005 for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated. ABRAXANE is also available in Europe, Canada, Russia, Australia, New Zealand, India, South Korea, Bhutan, Nepal, United Arab Emirates and China for the treatment of metastatic breast cancer.

In October 2012, ABRAXANE was approved by the U.S. Food and Drug Administration for the first-line treatment of locally advanced or metastatic non-small cell lung cancer, in combination with carboplatin, in patients who are not candidates for curative surgery or radiation therapy.

ABRAXANE is currently in various stages of investigation for the treatment of the following cancers: pancreatic, metastatic melanoma, bladder, ovarian, and expanded applications for breast cancer.

ABRAXANE® for Injectable Suspension (paclitaxel protein-bound particles for injectable suspension) (albumin bound) is indicated for the treatment of breast cancer after failure of combination chemotherapy for metastatic disease or relapse within 6 months of adjuvant chemotherapy. Prior therapy should have included an anthracycline unless clinically contraindicated.

ABRAXANE is indicated for the first-line treatment of locally advanced or metastatic non-small cell lung cancer, in combination with carboplatin, in patients who are not candidates for curative surgery or radiation therapy.

Important Safety Information

WARNING - NEUTROPENIA

  • Do not administer ABRAXANE therapy to patients who have baseline neutrophil counts of less than 1,500 cells/mm3. In order to monitor the occurrence of bone marrow suppression, primarily neutropenia, which may be severe and result in infection, it is recommended that frequent peripheral blood cell counts be performed on all patients receiving ABRAXANE
  • Note: An albumin form of paclitaxel may substantially affect a drug’s functional properties relative to those of drug in solution. DO NOT SUBSTITUTE FOR OR WITH OTHER PACLITAXEL FORMULATIONS

CONTRAINDICATIONS

Neutrophil Counts

  • ABRAXANE should not be used in patients who have baseline neutrophil counts of < 1,500 cells/mm3

Hypersensitivity

  • Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be rechallenged with the drug

WARNINGS AND PRECAUTIONS

Hematologic Effects

  • Bone marrow suppression (primarily neutropenia) is dose-dependent and a dose-limiting toxicity of ABRAXANE
  • Monitor for myelotoxicity by performing complete blood cell counts frequently, including prior to dosing on Day 1 for metastatic breast cancer (MBC) and Days 1, 8, and 15 for non-small cell lung cancer (NSCLC)
  • Do not administer ABRAXANE to patients with baseline absolute neutrophil counts (ANC) of less than 1,500 cells/mm3
  • In the case of severe neutropenia (1,500 cells/mm3 and platelets recover to >100,000 cells/mm3
  • In patients with NSCLC, resume treatment if recommended at permanently reduced doses for both weekly ABRAXANE and every-3-week carboplatin after ANC recovers to at least 1,500 cells/mm3 and platelet count of at least 100,000 cells/mm3 on Day 1 or to an ANC of at least 500 cells/mm3 and platelet count of at least 50,000 cells/mm3 on Days 8 or 15 of the cycle

Nervous System

  • Sensory neuropathy is dose- and schedule-dependent
  • The occurrence of Grade 1 or 2 sensory neuropathy does not generally require dose modification
  • If ≥ Grade 3 sensory neuropathy develops, treatment should be withheld until resolution to Grade 1 or 2 for MBC or until resolution to ≤ Grade1 for NSCLC followed by a dose reduction for all subsequent courses of ABRAXANE

Hypersensitivity

  • Severe and sometimes fatal hypersensitivity reactions, including anaphylactic reactions, have been reported
  • Patients who experience a severe hypersensitivity reaction to ABRAXANE should not be re-challenged with this drug

Hepatic Impairment

  • Because the exposure and toxicity of paclitaxel can be increased with hepatic impairment, administration of ABRAXANE in patients with hepatic impairment should be performed with caution
  • The starting dose should be reduced for patients with moderate or severe hepatic impairment

Albumin (Human)

  • ABRAXANE contains albumin (human), a derivative of human blood

Use in Pregnancy: Pregnancy Category D

  • ABRAXANE can cause fetal harm when administered to a pregnant woman
  • If this drug is used during pregnancy, or if the patient becomes pregnant while receiving this drug, the patient should be apprised of the potential hazard to the fetus
  • Women of childbearing potential should be advised to avoid becoming pregnant while receiving ABRAXANE

Use in Men

  • Men should be advised not to father a child while receiving ABRAXANE

ADVERSE REACTIONS

Randomized Metastatic Breast Cancer (MBC) Study

  • The most common adverse reactions (≥20%) with single-agent use of ABRAXANE in the MBC study were alopecia (90%), neutropenia (all cases 80%; severe 9%), sensory neuropathy (any symptoms 71%; severe 10%), abnormal ECG (all patients 60%; patients with normal baseline 35%), fatigue/asthenia (any 47%; severe 8%), myalgia/arthralgia (any 44%; severe 8%), AST elevation (any 39%), alkaline phosphatase elevation (any 36%), anemia (all cases 33%; severe 1%), nausea (any 30%; severe 3%), diarrhea (any 27%; severe
