BeiGene Announces Acceptance of Supplemental Import Drug Application in China for ABRAXANE® in Metastatic Pancreatic Cancer


CAMBRIDGE, Mass. and BEIJING, China, May 30, 2019 (GLOBE NEWSWIRE) -- BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a commercial-stage biopharmaceutical company focused on developing and commercializing innovative molecularly-targeted and immuno-oncology drugs for the treatment of cancer, today announced that the China National Medical Products Administration (NMPA, formerly known as CFDA) has accepted the supplemental import drug application for ABRAXANE® (paclitaxel protein-bound particles for injectable suspension) (albumin-bound), in combination with gemcitabine, as a first-line treatment of patients with metastatic adenocarcinoma of the pancreas (mPC). ABRAXANE was first approved in China in 2008 for the treatment of patients with metastatic breast cancer. It is currently marketed in China by BeiGene under an exclusive license from Celgene Corporation.

“We’re delighted about the NMPA’s acceptance of the supplemental import drug submission of ABRAXANE as a treatment for Chinese patients with metastatic adenocarcinoma of the pancreas,” said Dr. Xiaobin Wu, General Manager of China and President of BeiGene. “ABRAXANE has been an important global treatment option for patients with metastatic adenocarcinoma of the pancreas outside of China, and we strive to provide access to ABRAXANE in China to those patients for whom there is great need for additional treatments to combat this deadly disease.”

About Pancreatic Cancer
Pancreatic cancer is one of the deadliest cancers, with a nine percent five-year survival rate.i In 2018, there were an estimated 458,918 new cases globally, making it the 12th most common cancer in the world.ii Pancreatic cancer is difficult to detect in early stages, as the disease does not cause obvious symptoms. In addition, the pancreas is located deep in the abdomen, hindering the diagnosis of pancreatic cancer.

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 adenocarcinoma of the pancreas.

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.

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/mm3 or 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, hve 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
