Celgene Provides Update on Abraxane Combination Therapy in Metastatic Triple-Negative Breast Cancer and Pancreatic Cancer

SUMMIT, N.J.–(BUSINESS WIRE)–Celgene Corporation (NASDAQ: CELG) today announced two updates for ABRAXANE®(paclitaxel protein-bound particles for injectable suspension) (albumin-bound) in the treatment of metastatic triple-negative breast cancer and early stage pancreatic cancer.

Genentech, a member of the Roche Group, recently announced the accelerated approval of TECENTRIQ® (atezolizumab) in combination with ABRAXANE® for the treatment of adult patients with unresectable locally advanced or metastatic triple-negative breast cancer (TNBC) whose tumors express PD-L1 as determined by an FDA-approved test. This indication is approved under accelerated approval based on progression-free survival. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). This combination is the first cancer immunotherapy regimen approved for breast cancer and is based on results from the Phase 3 IMpassion130 study, which demonstrated that the combination of TECENTRIQ plus ABRAXANE compared to ABRAXANE monotherapy, as an initial (first-line) treatment, significantly reduced the risk of disease worsening or death (progression-free survival) in patients with metastatic or unresectable locally advanced triple negative breast cancer (TNBC) in the PD-L1 positive populations who had not received chemotherapy for metastatic disease.

“This is the second approval from the U.S. Food and Drug Administration of a PD-1/PD-L1 antibody in combination with ABRAXANE,” said Alise Reicin, M.D., President, Global Clinical Development for Celgene. “ABRAXANEcontinues to be studied with immunotherapy agents as a combination partner across a range of solid tumors.”

In addition, the Celgene-sponsored, pivotal, Phase 3 apact® study evaluating the investigational use of ABRAXANE in combination with gemcitabine following surgical resection (adjuvant treatment) in patients with pancreatic cancer did not achieve the primary endpoint of improvement in disease-free survival, as confirmed by independent radiological review, compared to gemcitabine alone. Overall survival, a secondary endpoint of the study, was improved, reaching nominal statistical significance, with ABRAXANE in combination with gemcitabine compared to gemcitabine alone. The safety profile observed in the apact study was consistent with previously reported studies of ABRAXANE. Data from apact will be submitted to a future medical meeting.

Currently, there are more than 130 studies evaluating the use of ABRAXANE in patients with pancreatic cancer in combination with more than 50 novel agents.

About apact

apact is an international, multicenter, randomized, open-label, controlled Phase 3 study (ClinicalTrials.gov, NCT01964430) to assess the efficacy of ABRAXANE in combination with gemcitabine versus gemcitabine alone as adjuvant therapy for patients with surgically resected pancreatic adenocarcinoma. The primary endpoint of the study was the independent assessment of disease-free survival (DFS); secondary endpoints included overall survival (OS) and safety. The study enrolled 866 patients randomized 1:1 to receive either ABRAXANE 125 mg/m2 followed by gemcitabine 1000 mg/m2, or gemcitabine 1000 mg/m2 monotherapy. Treatment was administered intravenously, weekly on Days 1, 8, and 15 of a 28-day cycle for a total of 6 cycles.

About Pancreatic Cancer

Each year, more than 350,000 people worldwide are diagnosed with pancreatic cancer – one of the deadliest cancers – with the majority of cases diagnosed in late stage. Despite advances in therapy over the past two decades that have led to doubled 5-year survival rates, pancreatic cancer 5-year survival is still only in the single digits – 8% – due to the complex nature of the disease and lack of symptoms until the disease has progressed.

Even among patients with localized pancreatic cancer, for whom surgery is potentially curative, survival remains poor and the rate of relapse is high. However, adjuvant chemotherapy has been proven to significantly improve survival compared with surgery alone. Despite the noted improvements with chemotherapy following surgery, recurrence rates of pancreatic cancer are still high with 69 to 75% of patients having a relapse within 2 years. There remains a high unmet medical need for more effective adjuvant therapies.

About Triple Negative Breast Cancer

Breast cancer is the second most common cancer among women in the United States. According to the American Cancer Society, it is estimated that about 266,000 American women will be diagnosed with invasive breast cancer in 2018, and nearly 41,000 will die from the disease. Approximately 10-20 percent of breast cancers are triple negative breast cancer (TNBC). TNBC is an aggressive form of the disease with a high unmet need. It can be more difficult to treat because it is not sensitive to hormone therapy or medicines that target HER2.

About ABRAXANE in Pancreatic Cancer

In September 2013, the U.S. Food and Drug Administration (FDA) approved ABRAXANE in combination with gemcitabine as first-line treatment of patients with metastatic pancreatic cancer. The current indication remains unchanged and clinical trials continue building on the foundation of ABRAXANE in combination with gemcitabine for a new wave of potential treatments, such as an ongoing Phase 2 cooperative group trial with SWOG S1505 (ClinicalTrials.gov, NCT02562716) investigating the safety and effectiveness of ABRAXANE in combination with gemcitabine as neoadjuvant treatment for localized pancreatic head adenocarcinoma.

ABRAXANE is not approved for the adjuvant treatment of pancreatic cancer.

About ABRAXANE

Indications

ABRAXANE 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.

ABRAXANE is indicated for the first-line treatment of patients with metastatic adenocarcinoma of the pancreas, in combination with gemcitabine.

Important Safety Information

WARNING – NEUTROPENIA

  • Do not administer ABRAXANE therapy to patients who have baseline neutrophil counts of less than 1500 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 <1500 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. In clinical studies, Grade 3-4 neutropenia occurred in 34% of patients with metastatic breast cancer (MBC), 47% of patients with non–small cell lung cancer (NSCLC), and 38% of patients with pancreatic cancer
  • Monitor for myelotoxicity by performing complete blood cell counts frequently, including prior to dosing on Day 1 (for MBC) and Days 1, 8, and 15 (for NSCLC and for pancreatic cancer)
  • Do not administer ABRAXANE to patients with baseline absolute neutrophil counts (ANC) of less than 1500 cells/mm3
  • In the case of severe neutropenia (<500 cells/mm3 for 7 days or more) during a course of ABRAXANE therapy, reduce the dose of ABRAXANE in subsequent courses in patients with either MBC or NSCLC
  • In patients with MBC, resume treatment with every-3-week cycles of ABRAXANE after ANC recovers to a level >1500 cells/mm3 and platelets recover to a level >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 1500 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
  • In patients with adenocarcinoma of the pancreas, withhold ABRAXANE and gemcitabine if the ANC is less than 500 cells/mm3or platelets are less than 50,000 cells/mm3 and delay initiation of the next cycle if the ANC is less than 1500 cells/mm3 or platelet count is less than 100,000 cells/mm3 on Day 1 of the cycle. Resume treatment with appropriate dose reduction if recommended

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, withhold ABRAXANE treatment until resolution to Grade 1 or 2 for MBC or until resolution to ≤ Grade 1 for NSCLC and pancreatic cancer followed by a dose reduction for all subsequent courses of ABRAXANE

Sepsis

  • Sepsis occurred in 5% of patients with or without neutropenia who received ABRAXANE in combination with gemcitabine
  • Biliary obstruction or presence of biliary stent were risk factors for severe or fatal sepsis
  • If a patient becomes febrile (regardless of ANC), initiate treatment with broad-spectrum antibiotics
  • For febrile neutropenia, interrupt ABRAXANE and gemcitabine until fever resolves and ANC ≥1500 cells/mm3, then resume treatment at reduced dose levels

Pneumonitis

  • Pneumonitis, including some cases that were fatal, occurred in 4% of patients receiving ABRAXANE in combination with gemcitabine
  • Monitor patients for signs and symptoms and interrupt ABRAXANE and gemcitabine during evaluation of suspected pneumonitis
  • Permanently discontinue treatment with ABRAXANE and gemcitabine upon making a diagnosis of pneumonitis

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 rechallenged with this drug
  • Cross-hypersensitivity between ABRAXANE and other taxane products has been reported and may include severe reactions such as anaphylaxis. Patients with a previous history of hypersensitivity to other taxanes should be closely monitored during initiation of ABRAXANE therapy

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
  • Patients with hepatic impairment may be at an increased risk of toxicity, particularly from myelosuppression, and should be monitored for development of profound myelosuppression
  • For MBC and NSCLC, the starting dose should be reduced for patients with moderate or severe hepatic impairment
  • For pancreatic adenocarcinoma, ABRAXANE is not recommended for patients with moderate to severe hepatic impairment (total bilirubin >1.5 x ULN and AST ≤10 x ULN)

Albumin (Human)

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

Embryo Fetal Toxicity

  • Based on mechanism of action and findings in animals, ABRAXANE can cause fetal harm when administered to a pregnant woman
  • Advise females of reproductive potential of the potential risk to a fetus.
  • Advise females of reproductive potential to use effective contraception and avoid becoming pregnant during treatment with ABRAXANE and for at least six months after the last dose of ABRAXANE
  • Advise male patients with female partners of reproductive potential to use effective contraception and avoid fathering a child during treatment with ABRAXANE and for at least three months after the last dose of ABRAXANE
