      RARITAN, N.J., February 28, 2023 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) seeking approval of niraparib in combination with abiraterone acetate, in the form of a dual-action tablet (DAT), plus prednisone, for the treatment of patients with BRCA-positive metastatic castration-resistant prostate cancer (mCRPC). If approved, this will be the first DAT formulation available in the U.S. to patients with mCRPC with BRCA mutations, which are a type of homologous recombination repair (HRR) gene alteration.

      “Patients with mCRPC and BRCA mutations face a more aggressive form of prostate cancer and high unmet needs in terms of treatment options. The data supporting this submission reinforce the importance of biomarker testing to identify the subgroups of patients that are most likely to respond to a targeted treatment option,” said Peter Lebowitz, M.D., Ph.D., Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC. “This submission further represents our commitment at Janssen to discover and develop precision medicine approaches and combination therapies to help improve outcomes for patients living with genetically defined disease.”

      Prostate cancer is one of the most common cancers in the U.S., with an estimated 268,490 new cases diagnosed in 2022.[1] Approximately 10 to 50 percent of patients progress to mCRPC within three years of diagnosis,[2] of which an estimated 10 to 15 percent harbor a BRCA mutation.[3],[4]

      The combination of niraparib, a highly selective poly (ADP-ribose) polymerase (PARP) inhibitor, and abiraterone acetate, a prodrug of abiraterone, a CYP17 inhibitor, plus prednisone, targets two oncogenic drivers in patients with mCRPC: the androgen receptor axis and HRR gene alterations. The combination of niraparib with abiraterone acetate plus prednisone (AAP) is intended for patients with BRCA mutations who have not received prior treatment for mCRPC except for standard of care, next-generation androgen receptor inhibitors and up to four months of AAP. Through the DAT formulation, this therapeutic option may help improve compliance and reduce pill burden.

      The NDA is supported by data from the MAGNITUDE study (NCT03748641), a Phase 3, randomized, double-blind, placebo-controlled, multicenter study evaluating the safety and efficacy of niraparib plus AAP as a first-line treatment in patients with mCRPC, with or without alterations in HRR associated genes.[1] Patients with HRR gene alterations were randomized to receive niraparib 200 mg once daily plus AAP [n=212], or placebo plus AAP [n=211].

      First results from MAGNITUDE were presented at the American Society of Clinical Oncology – Genitourinary Cancers Symposium (ASCO GU) 2022 Annual Meeting (Abstract #12) for the primary endpoint of investigator-evaluated radiographic progression-free survival (rPFS) in all HRR-positive patients, as well as patients with BRCA mutations, receiving niraparib plus AAP.[5] Results from the secondary interim analysis (IA2) were presented at the ASCO GU 2023 Annual Meeting (Abstract #170). In IA2, at 26.8 months of median follow-up, researchers further reviewed time to symptomatic progression (TSP) and time-to-initiation of cytotoxic chemotherapy (TCC) in the HRR-positive population and the BRCA subgroup.

      The study continues to collect data on the secondary endpoints, which include TCC, TSP and overall survival.

      About niraparib
      Niraparib is an orally administered, highly selective poly (ADP-ribose) polymerase (PARP) inhibitor that is currently being studied by Janssen for the treatment of patients with prostate cancer.

      Additional ongoing studies include the Phase 3 AMPLITUDE study, evaluating the combination of niraparib and AAP in a biomarker-selected patient population with metastatic castration-sensitive prostate cancer (mCSPC).[6]

      In April 2016, Janssen Biotech, Inc. entered a worldwide (except Japan) collaboration and license agreement with TESARO, Inc. (acquired by GlaxoSmithKline [GSK] in 2019) for exclusive rights to niraparib in prostate cancer.

      In the United States, niraparib is indicated for the maintenance treatment of adult patients with advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to first-line platinum-based chemotherapy; and for the maintenance treatment of adult patients with deleterious or suspected deleterious germline BRCA-mutated recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy. Niraparib is currently marketed by GSK as ZEJULA®.[7]

      In April 2022, Janssen submitted a marketing authorisation application to the European Medicines Agency seeking approval for niraparib in combination with abiraterone acetate in the form of a DAT, plus prednisone or prednisolone, based on data from the MAGNITUDE study. Marketing authorisation applications are under review across a number of countries globally.

      On February 24, 2023, the European Medicines Agency’s Committee for Medicinal Products for Human Use issued a positive opinion for niraparib in combination with abiraterone acetate in the form of a DAT, plus prednisone or prednisolone, for the treatment of adult patients with mCRPC and BRCA mutations (germline and/or somatic) in whom chemotherapy is not clinically indicated.

      About metastatic castration-resistant prostate cancer
      Metastatic castration-resistant prostate cancer characterizes cancer that no longer responds to androgen deprivation therapy and has spread to other parts of the body. The most common metastatic sites are bones, followed by lungs and liver.[8] Prostate cancer is the second most common cancer in men worldwide, behind lung cancer.3 More than one million patients around the world are diagnosed with prostate cancer each year.[9] Patients with mCRPC and HRR gene alterations, of which BRCA mutations are the most common, are more likely to have aggressive disease, poor outcomes and a shorter survival time.[2],[3] ,[4] ,[5]

      About MAGNITUDE
      MAGNITUDE (NCT03748641) is a Phase 3, randomized, double-blind, placebo-controlled, multicenter clinical study evaluating the safety and efficacy of the combination of niraparib and AAP for patients with mCRPC, with or without certain HRR gene alterations, and who have not received prior therapy for mCRPC except for standard of care, next-generation androgen receptor inhibitors and up to four months of AAP. Patients were randomized to receive either niraparib and AAP or placebo and AAP. Additionally in an open-label cohort of HRR-positive patients, all patients received the DAT formulation of niraparib and abiraterone acetate plus prednisone.2 The primary endpoint of the MAGNITUDE trial is rPFS determined by blinded independent central review. Secondary endpoints include TCC, TSP and overall survival.[2]

      About abiraterone acetate
      Abiraterone acetate is an orally administered androgen biosynthesis inhibitor. In the United States, abiraterone acetate is indicated with prednisone for the treatment of mCRPC and high-risk mCSPC.
