Anti-PD-L1 Immunotherapy Plus ABRAXANE® Significantly Reduced the Risk of Disease Worsening or Death in Patients with Metastatic or Locally Advanced Triple Negative Breast Cancer in Phase III IMpassion130 Study
SUMMIT, N.J.--(BUSINESS WIRE)--Jul 10, 2018--Celgene Corporation (NASDAQ:CELG) today announced that the Phase III IMpassion130 study, which was sponsored by Roche, met its co-primary endpoint of progression-free survival (PFS). This is the first phase III study to demonstrate a statistically significant PFS improvement in first-line metastatic or unresectable locally advanced triple negative breast cancer (TNBC), a type of breast cancer with high unmet need.
Results demonstrated that the investigational combination of TECENTRIQ ® (atezolizumab) plus ABRAXANE ® (paclitaxel protein-bound particles for injectable suspension) (albumin-bound) compared to ABRAXANE ® monotherapy, as an initial (first-line) treatment, significantly reduced the risk of disease worsening or death (PFS) in patients with metastatic or unresectable locally advanced TNBC in the intention-to-treat (ITT) and PD-L1 positive populations. Overall survival is encouraging in the PD-L1 positive population at this interim analysis, and follow up will continue until the next planned analysis. Safety in the TECENTRIQ ® plus ABRAXANE ® arm appeared consistent with the known safety profiles of the individual medicines, and no new safety signals were identified with the combination.
“The IMpassion130 results are extremely encouraging for patients with this highly aggressive form of breast cancer for which there are limited options,” said Jay Backstrom, M.D., Chief Medical Officer for Celgene. “This is the third positive Phase III study to demonstrate a clinical benefit with TECENTRIQ ® plus ABRAXANE ® as part of a treatment regimen; the other studies evaluated this investigational combination in non-small cell lung cancer patients. These data demonstrate the potential role of ABRAXANE ® as a preferred chemotherapy partner for immunotherapy combinations.”
Results will be presented at an upcoming medical meeting.
ABRAXANE ® is not approved in combination with TECENTRIQ ® for any indication in any geography.
About the IMpassion130 Study
IMpassion130 is a Phase III multicenter, randomized, double-blind study evaluating the efficacy, safety, and pharmacokinetics of TECENTRIQ ® and ABRAXANE ® compared with placebo in combination with ABRAXANE ® in people with locally advanced or metastatic TNBC who have not received prior systemic therapy for metastatic breast cancer. The study enrolled 902 people who were randomized equally (1:1). The co-primary endpoints were progression-free survival (PFS) per investigator assessment (RECIST 1.1) and overall survival (OS). PFS and OS were assessed in all randomized participants [intention-to-treat (ITT)] and in those whose disease expressed the PD-L1 protein. Secondary endpoints included objective response rate, duration of response and time to deterioration in Global Health Status/Health-Related Quality of Life.
During the treatment duration, people in:Arm A received TECENTRIQ ® at a fixed dose of 840 milligrams via intravenous (IV) infusion on Days 1 and 15 of each 28-day cycle and ABRAXANE ® at a dose of 100 milligrams per square meter via IV infusion on Days 1, 8, and 15 of each 28-day cycle. ABRAXANE ® was administered for a target of at least 6 cycles, with no maximum. Participants received both agents until unacceptable toxicity or disease progression. Arm B received ABRAXANE ® at a dose of 100 milligrams per square meter via IV infusion on Days 1, 8, and 15 of each 28-day cycle. ABRAXANE ® was administered for a target of at least 6 cycles, with no maximum, and placebo was administered via IV infusion on Days 1 and 15 of each 28-day cycle. Participants received both agents until unacceptable toxicity or disease progression.
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.
TECENTRIQ®is a registered trademark of Genentech, a member of the Roche Group.
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.
Important Safety Information for ABRAXANE ®
Neutrophil CountsABRAXANE should not be used in patients who have baseline neutrophil counts of <1500 cells/mm 3
HypersensitivityPatients who experience a severe hypersensitivity reaction to ABRAXANE should not be rechallenged with the drug
WARNINGS AND PRECAUTIONS
Hematologic EffectsBone 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) and 47% of patients with non–small cell lung cancer (NSCLC) 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 Do not administer ABRAXANE to patients with baseline absolute neutrophil counts (ANC) of less than 1500 cells/mm 3 In the case of severe neutropenia (<500 cells/mm 3 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/mm 3 and platelets recover to a level >100,000 cells/mm 3 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/mm 3 and platelet count of at least 100,000 cells/mm 3 on Day 1 or to an ANC of at least 500 cells/mm 3 and platelet count of at least 50,000 cells/mm 3 on Days 8 or 15 of the cycle
Nervous SystemSensory 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 followed by a dose reduction for all subsequent courses of ABRAXANE
HypersensitivitySevere 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
Hepatic ImpairmentBecause 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
Albumin (Human)ABRAXANE contains albumin (human), a derivative of human blood
Use in Pregnancy: Pregnancy Category DABRAXANE 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 MenMen should be advised not to father a child while receiving ABRAXANE

Postmarketing Experience With ABRAXANE and Other Paclitaxel FormulationsSevere and sometimes fatal hypersensitivity reactions have been reported with ABRAXANE. The use of ABRAXANE in patients previously exhibiting hypersensitivity to paclitaxel injection or human albumin has not been studied There have been reports of congestive heart failure, left ventricular dysfunction, and atrioventricular block with ABRAXANE, primarily among individuals with underlying cardiac history or prior exposure to cardiotoxic drugs There have been reports of extravasation of ABRAXANE. Given the possibility of extravasation, it is advisable to monitor closely the ABRAXANE infusion site for possible infiltration during drug administration
DRUG INTERACTIONSCaution should be exercised when administering ABRAXANE concomitantly with medicines known to inhibit or induce either CYP2C8 or CYP3A4
USE IN SPECIFIC POPULATIONS
Nursing MothersIt is not known whether paclitaxel is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother
PediatricThe safety and effectiveness of ABRAXANE in pediatric patients have not been evaluated
GeriatricA higher incidence of epistaxis, diarrhea, dehydration, fatigue, and peripheral edema was found in patients 65 years or older who received ABRAXANE for MBC in a pooled analysis of clinical studies Myelosuppression, peripheral neuropathy, and arthralgia were more frequent in patients ≥65 years of age treated with ABRAXANE and carboplatin in NSCLC
Renal ImpairmentThere are insufficient data to permit dosage recommendations in patients with severe renal impairment or end stage renal disease (estimated creatinine clearance <30 mL/min)
DOSAGE AND ADMINISTRATIONDo not administer ABRAXANE to any patient with total bilirubin greater than 5 x ULN or AST greater than 10 x ULN For MBC and NSCLC, reduce starting dose in patients with moderate to severe hepatic impairment Dose reductions or discontinuation may be needed based on severe hematologic or neurologic toxicity Monitor patients closely
