Investigational Data Presented at ASCO GI Evaluate ABRAXANE® Regimen for Patients with Locally Advanced Pancreatic Cancer

Phase II LAPACT trial results reported on the safety and efficacy of ABRAXANE + gemcitabine induction therapy on tumor burden, disease control, and symptoms

SUMMIT, N.J.--(BUSINESS WIRE)-- Celgene Corporation (NASDAQ: CELG) today announced primary endpoint findings and updated results of secondary endpoints from the phase II international LAPACT trial of ABRAXANE® (paclitaxel protein-bound particles for injectable suspension) (albumin-bound) plus gemcitabine in patients with locally advanced pancreatic cancer. The results were presented today at the 2018 American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO GI) in San Francisco, California.

An analysis of patients with newly diagnosed, locally advanced pancreatic cancer treated with up to 6 cycles of ABRAXANE + gemcitabine as an investigational induction therapy (n=106) found that patients had a median time to treatment failure (TTF) of 8.8 months (90% CI: 6.67-9.82), which exceeded the protocol-specified target of 6.6 months (primary endpoint). Secondary endpoints included evaluation of the disease control rate (DCR), overall response rate (ORR), progression free survival (PFS) and overall survival (OS) in patients treated with an ABRAXANE + gemcitabine induction therapy. The updated analysis found a 77.6% DCR ≥ 16 wks (DCR ≥ 16 wks: stable disease (SD) ≥ 16 wks = 44.9%, CR = 0%, PR = 32%) and 65.4% DCR ≥ 24 wks (DCR ≥ 24 wks: SD ≥ 24 wks = 32.7%, CR = 0%, PR = 32%). The ORR was 32% (CR=0%, PR=32%), the median PFS was 10.8 months (9,26-11.63; 90% CI) and 12-month estimated OS was 72% (64.5% - 78.9%; 90% CI). One or more treatment emergent adverse event occurred in 99% of patients during induction. The most common Grade ≥ 3 adverse events (AE) (≥10%) were neutropenia (42%), anemia (11%), and fatigue (10%).

"Pancreatic cancer remains an extremely challenging disease to treat because it is often diagnosed at the metastatic stage, and even those diagnosed with locally advanced disease typically have a poor prognosis," said Dr. Pascal Hammel, Gastroenterologist/Oncologist, Hôpital Beaujon, Clichy France. "Disease control is key in our patients with locally advanced disease, as it may lead to opportunities for additional treatment interventions, including radiotherapy, or even, in some favorable cases, surgical resection. The results from this study are encouraging, as it shows that induction therapy has the potential to help us achieve disease control in these locally advanced patients."

In this prospective, phase II trial conducted in the US, Canada and Europe, patients with protocol-defined locally advanced, unresectable pancreatic cancer received an induction regimen of up to 6 cycles of ABRAXANE + gemcitabine, followed by the investigator's choice (IC) of either (a) continuation of the ABRAXANE + gemcitabine regimen, (b) treatment with chemoradiation, or (c) surgery. More than half of patients (57.5%, n = 61/106) completed the induction phase with ABRAXANE + gemcitabine treatment. Forty two percent (45/106) of patients did not complete induction treatment and the reasons for treatment discontinuation during induction included adverse events (n = 20), progressive disease (n = 8), protocol non-compliance (n = 5), physician decision (n = 6), death (n = 2), and other reasons (n = 4). At the time of data cut-off, 45 patients in the intent to treat cohort received IC therapy after induction: 11% (12/106) of patients continued ABRAXANE + gemcitabine per the protocol; 16% (17/106) received chemoradiation; and 15% of patients (16/106) with unresectable disease at the start of the study underwent tumor resection surgery following ABRAXANE + gemcitabine induction therapy. The LAPACT presentation also reported patient-reported quality of life findings across twenty-nine different symptom measures using the EORTC QLQ-C30 questionnaires.

Other relevant grade ≥3 TEAEs included thrombocytopenia (7.5%), peripheral sensory neuropathy (3.8%), diarrhea (3.8%), and febrile neutropenia (3.8%). AEs of any grade included: neutropenia (58.5%), fatigue (50%), anemia (47.2%), diarrhea (46.2%), thrombocytopenia (41.5%), peripheral sensory neuropathy (23.6%), and febrile neutropenia (3.8%).

"Since its approval to treat metastatic pancreatic cancer in 2013, the ABRAXANE + gemcitabine regimen has become a standard of care in first-line metastatic pancreatic cancer," said Nadim Ahmed, President, Hematology and Oncology for Celgene. "The findings from LAPACT offer insight into the potential of ABRAXANE-based treatment for locally advanced pancreatic cancer patients and it's encouraging to see a nearly 9-month time to treatment failure in these patients treated with an ABRAXANE regimen."

ABRAXANE is not indicated for the first-line treatment of locally advanced pancreatic cancer.

ABOUT LAPACT,

LAPACT is an international, non-randomized, open-label, multi-center, phase II clinical trial conducted at 42 centers in 5 countries. The study evaluated the safety and efficacy of the investigational use of ABRAXANE in combination with gemcitabine as a first-line treatment of patients with locally advanced pancreatic cancer who were not eligible for resection surgery at trial initiation.

The trial evaluated 106 patients with locally advanced pancreatic cancer who had not received prior treatment for their pancreatic cancer and were classified as unresectable at the start of the trial. Patients were given ABRAXANE 125 mg/m2 followed by gemcitabine 1000 mg/m2 on days 1, 8 and 15 of a 28-day cycle for up to six cycles. Patients completing six cycles of treatment were given subsequent investigator-determined treatment of either: continuation of the ABRAXANE + gemcitabine regimen; chemoradiation therapy with capecitabine or gemcitabine + radiation; or surgical intervention. The median age of the patients was 65 years.

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 ABRAXANE
