Janssen Pharma bags breakthrough designation for niraparib in prostate cancer

The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation for niraparib, an orally-administered poly ADP-ribose polymerase (PARP) inhibitor, for the treatment of patients with BRCA1/2 gene-mutated metastatic castration-resistant prostate cancer (mCRPC) who have received prior taxane chemotherapy and androgen receptor (AR)-targeted therapy. A Breakthrough Therapy Designation is granted to expedite the development and regulatory review of an investigational medicine that is intended to treat a serious or life-threatening condition.1 The criteria for Breakthrough Therapy Designation require preliminary clinical evidence that demonstrates the drug may have substantial improvement on at least one clinically significant endpoint over available therapy.[1]

BRCA1/2 mutations are the most common DNA-repair gene defects (DRD) in patients with mCRPC.2 Patients with a DRD in BRCA1/2 are at an elevated risk for both prostate cancer occurrence and more aggressive disease.[2]

“Niraparib is a PARP inhibitor that we believe may help address an important unmet need for patients with metastatic castration-resistant prostate cancer who have mutations in DNA-repair genes,” said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Janssen Research & Development, LLC. “We are pleased with the FDA’s Breakthrough Therapy Designation as we continue the clinical development of niraparib, and we look forward to working with the agency in our continued focus and commitment to bring new advancements to patients diagnosed with prostate cancer.”

The Breakthrough Therapy Designation is based on data from the GALAHAD study, a Phase 2, multicenter, open-label clinical trial evaluating the efficacy and safety of niraparib in the treatment of adult patients with mCRPC and DRD who had received treatment with next-generation androgen-receptor targeting therapies and docetaxel.[3] Data from the Phase 2 GALAHAD study were recently presented at the European Society for Medical Oncology (ESMO) 2019 Annual Congress as a late-breaking abstract.

EMA validates Incyte’s MAA for retifanlimab to treat metastatic squamous cell anal carcinoma

Incyte, global biopharmaceutical company, announced the validation of the Company’s Marketing Authorization Application (MAA) for retifanlimab, an intravenous PD-1 inhibitor, as a potential treatment for adult patients with locally advanced or metastatic squamous cell anal carcinoma (SCAC) who have progressed on, or who are intolerant of, platinum-based chemotherapy. The European Medicines Agency’s (EMA) validation of the MAA confirms that the submission is sufficiently complete to begin the formal review process. “While the incidence of SCAC is increasing in Europe, treatment options for advanced disease are limited in their effectiveness, and there are no approved options once patients have progressed on standard therapy,” said Lance Leopold, M.D., Group vice president, Immuno-Oncology Clinical Development, Incyte. “The EMA validation of the MAA for retifanlimab – which follows the recent US Food & Drug Administration acceptance of our Biologics License Application for Priority R...

Tumour-targeting drug paves way for bone cancer treatment

 The treatment of osteosarcoma, the most common tumour of bone, is challenging, but a new study is offering hope to the patients with this disease. The study led by The University of  Texas MD Anderson Cancer Centre  found that a drug, known as bone metastasis-targeting peptidomimetic (BMTP-11), has potential as a new therapeutic strategy for this devastating illness. Results from the preclinical study looked at BMTP-11 alone and in combination with the chemotherapy agent gemcitabine. Although osteosarcoma is a relatively rare cancer, it is a leading disease-related cause of death in children and young adults ages 10 to 20. However, over the last 25 years, the five-year survival rate has remained unchanged, and the treatment options for these patients are few. In addition, the side effects of available treatment options often are significant and cumulative, and may cause other health problems and damage to major organs. "What's novel about this treatment is that...

Merck’s Keytruda plus platinum- and fluoropyrimidine-based chemotherapy receives US FDA nod to treat certain patients with locally advanced/metastatic esophageal or GEJ carcinoma

Merck, known as MSD outside the United States and Canada, announced that the US Food and Drug Administration (FDA) has approved Keytruda, Merck’s anti-PD-1 therapy, for the treatment of patients with locally advanced or metastatic esophageal or gastroesophageal junction (GEJ) (tumors with epicenter 1 to 5 centimeters above the GEJ) carcinoma that is not amenable to surgical resection or definitive chemoradiation in combination with platinum- and fluoropyrimidine-based chemotherapy. The approval is based on results from the phase 3 KEYNOTE-590 trial, which demonstrated significant improvements in overall survival (OS), progression-free survival (PFS) and objective response rate (ORR) for Keytruda plus fluorouracil (FU) and cisplatin versus FU and cisplatin alone, regardless of histology or PD-L1 expression status. For OS and PFS, Keytruda plus FU and cisplatin reduced the risk of death by 27% (HR=0.73 [95% CI, 0.62-0.86]; p<0.0001) and reduced the risk of disease progression or death...
