- Phase 3 SPARTAN data served as basis for approval, which showed apalutamide decreased the risk of distant metastasis or death by 72 percent and improved median metastasis-free survival by more than two years1
BEERSE, Belgium --(BUSINESS WIRE)-- 16.01.2019 --
The Janssen Pharmaceutical Companies of Johnson & Johnson today announced that the European Commission (EC) has granted marketing authorisation for ERLEADA® (apalutamide), a next generation oral androgen receptor inhibitor for the treatment of adult patients with non-metastatic castration-resistant prostate cancer (nmCRPC) who are at high risk of developing metastatic disease.
The EC approval is based on data from the pivotal Phase 3 SPARTAN study, which was published in The New England Journal of Medicine. The study assessed the efficacy and safety of apalutamide plus androgen deprivation therapy (ADT) versus placebo plus ADT in patients with nmCRPC who had a rapidly rising prostate specific antigen (PSA) level despite receiving continuous ADT. Findings from the study showed that apalutamide plus ADT, significantly reduced the risk of developing distant metastasis or death (metastasis free survival [MFS]) by 72 percent, compared to placebo in combination with ADT (HR = 0.28; 95% CI, 0.23-0.35; P < 0.001). The median MFS was improved by over two years (40.5 months vs. 16.2 months) in patients with nmCRPC whose PSA is rapidly rising.1
"One of the key goals in prostate cancer treatment is to delay the disease from spreading. Once the cancer spreads, it can become less responsive to treatment, impacting patients' quality of life and ultimately worsening their prognosis. Median survival for these patients is approximately three years," said Dr Simon Chowdhury, Consultant Medical Oncologist, Guy's and St Thomas' Hospitals, London. "It is crucial that we delay the development of metastases for as long as possible. Therefore, the approval of apalutamide, a treatment which can significantly increase time without metastases, is a major step-forward for patients with prostate cancer."*
"Today's approval of apalutamide is a significant milestone and we are pleased that we can now offer patients with high-risk non-metastatic castration-resistant prostate cancer a new treatment option," said Dr Ivo Winiger-Candolfi M.D., Janssen Oncology Solid Tumor Therapy Area Lead, Europe, Middle East and Africa, Cilag GmbH International. "Bringing medicines to patients at earlier stages of disease is vital, and the approval of apalutamide could mark a step change in how we treat prostate cancer in the future. Crucially, treating patients at this stage could delay the cancer from spreading, a key part of our commitment to patients living with this disease and to their families."
The most common Grade 3/4 treatment-emergent adverse events in the SPARTAN study were hypertension (14.3 percent vs. 11.8 percent), rash (5.2 percent vs. 0.3 percent), fall (1.7 percent vs. 0.8 percent) and fracture (2.7 percent vs. 0.8 percent). Treatment discontinuation due to adverse events was 11 percent in the apalutamide arm compared to 7 percent in the placebo arm. Rates of serious adverse events were similar in the apalutamide in combination with ADT arm versus placebo in combination with ADT arm (25 percent vs. 23 percent respectively).1
About Non-Metastatic Castration-Resistant Prostate Cancer
Non-metastatic castration-resistant prostate cancer (CRPC) refers to a disease stage when the cancer no longer responds to medical or surgical treatments that lower testosterone, but has not yet been discovered in other parts of the body using a bone scan or CT scan.2 Features include: lack of detectable metastatic disease; rapidly rising prostate-specific antigen while on androgen deprivation therapy (ADT) and serum testosterone level below 50 ng/dL.3 Ninety percent of patients with non-metastatic CRPC will eventually develop bone metastases, which can lead to pain, fractures and spinal cord compression.3 The relative 5-year survival rate for patients with distant stage castration sensitive or castration resistant prostate cancer is 30 percent.4,5
Apalutamide is a next-generation oral androgen receptor (AR) inhibitor that blocks the androgen signaling pathway in prostate cancer cells. Apalutamide inhibits the growth of cancer cells in three ways: by preventing the binding of androgen to the AR; by stopping the AR from entering the cancer cells; and by preventing the AR from binding to the DNA of the cancer cell.6
In the United States, apalutamide received approval from the Food and Drug Administration for the treatment of patients with nmCRPC in February 2018, shortly followed by approvals in Canada, Australia, Argentina and Brazil.7,8,9,10
