FDA to Review Supplement Containing Long-Term Survival Data For VELCADE(R) (bortezomib) For InjectionData from landmark VISTA trial accepted for review
CAMBRIDGE, Mass.--(HSMN NewsFeed)--Millennium: The Takeda Oncology Company today announced the U.S. Food and Drug Administration (FDA) has accepted for review the Company’s supplemental new drug application (sNDA) based on long- term overall survival (OS) data from the landmark VISTA1 trial examining the use of VELCADE based therapy in patients with previously untreated multiple myeloma (MM).
“This is the largest Phase III registration study to report long-term overall survival in previously untreated multiple myeloma patients,” said Nancy Simonian, M.D., Chief Medical Officer, Millennium. “This submission of data from the pre-planned long-term survival assessment represents an important milestone in the development of VELCADE.”
VISTA long-term OS data are expected to be presented at a forthcoming scientific conference. VISTA was conducted by Ortho Biotech Oncology Research & Development, a unit of Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (JJPRD) in collaboration with Millennium.
About Multiple Myeloma
Multiple myeloma is the second most common hematologic malignancy and although the disease is predominantly a cancer of the elderly (the median age of onset is 70 years), recent statistics indicate both increasing incidence and younger age of onset. In the U.S., more than 50,000 individuals have MM and 20,000 new cases are diagnosed each year. Worldwide there are approximately 74,000 new cases and over 45,000 deaths annually.
The Phase III VISTA trial was conducted by Millennium and its co-development partner JJPRD. The trial randomized 682 patients with newly diagnosed multiple myeloma, ineligible for stem cell transplantation, to receive either VELCADE, melphalan and prednisone (VcMP) or melphalan and prednisone (MP) alone, a recognized standard of care in this treatment setting. Patients were enrolled at 151 clinical trial sites in 22 countries. The primary endpoint of the trial was time-to-disease progression, with secondary endpoints including overall survival, progression-free survival, complete remission rate, and safety. Results from the study are based on European Group for Blood and Marrow Transplantation (EMBT) and include:
- Immunofixation-negative complete remission (CR) rate was 35 percent in the VcMP arm compared to 5 percent in the MP arm (p<0.000001); EBMT criteria showed a CR rate of 30 percent in the VcMP arm compared to 4 percent in the MP arm.
- The median duration of response was 24 months for patients achieving CR in the VcMP arm compared to 13 months for those in the MP arm.
- Time-to-disease progression (TTP) in the VcMP arm was 24 months compared to 17 months in the MP arm (p=0.0000001).
- VcMP demonstrated statistical significance in overall survival with a 40 percent reduction in risk of death (p=0.0078); median survival was not reached at initial analysis due to a short follow-up of 16 months. These data are updated in the sNDA filing.
- The median treatment duration was 46 weeks and discontinuation due to adverse events was low and similar in both arms.
VELCADE is co-developed by Millennium Pharmaceuticals, Inc. and Johnson & Johnson Pharmaceutical Research & Development, L.L.C. Millennium is responsible for commercialization of VELCADE in the U.S., Janssen-Cilag is responsible for commercialization in Europe and the rest of the world. Janssen Pharmaceutical K.K. is responsible for commercialization in Japan. VELCADE is approved in more than 87 countries worldwide.
Important Safety Information
In the U.S., VELCADE is indicated for the treatment of patients with multiple myeloma. VELCADE also is indicated for the treatment of patients with mantle cell lymphoma who have received at least one prior therapy. VELCADE is contraindicated in patients with hypersensitivity to bortezomib, boron or mannitol. VELCADE should be administered under the supervision of a physician experienced in the use of antineoplastic therapy.
Risks associated with VELCADE therapy include new or worsening peripheral neuropathy, hypotension throughout therapy, cardiac and pulmonary disorders, reversible posterior leukoencephalopathy syndrome, gastrointestinal adverse events, thrombocytopenia, neutropenia, tumor lysis syndrome and hepatic events. Women of childbearing potential should avoid becoming pregnant while being treated with VELCADE. Nursing mothers are advised not to breastfeed while receiving VELCADE. Cases of severe sensory and motor peripheral neuropathy have been reported. The long-term outcome of peripheral neuropathy has not been studied in mantle cell lymphoma. Acute development or exacerbation of congestive heart failure, and new onset of decreased left ventricular ejection fraction has been reported, including reports in patients with no risk factors for decreased left ventricular ejection fraction. There have been reports of acute diffuse infiltrative pulmonary disease of unknown etiology such as pneumonitis, interstitial pneumonia, lung infiltration and Acute Respiratory Distress Syndrome in patients receiving VELCADE. Some of these events have been fatal. There have been reports of Reversible Posterior Leukoencephalopathy Syndrome (RPLS) in patients receiving VELCADE. RPLS is a rare, reversible, neurological disorder which can present with seizure, hypertension, headache, lethargy, confusion, blindness, and other visual and neurological disturbances. VELCADE is associated with thrombocytopenia and neutropenia. There have been reports of gastrointestinal and intracerebral hemorrhage in association with VELCADE. Transfusions may be considered. Complete blood counts (CBC) should be frequently monitored during treatment with VELCADE. Cases of acute liver failure have been reported in patients receiving multiple concomitant medications and with serious underlying medical conditions. Patients who are concomitantly receiving VELCADE and drugs that are inhibitors or inducers of cytochrome P450 3A4 should be closely monitored for either toxicities or reduced efficacy. Patients on oral antidiabetic medication while receiving VELCADE should check blood sugar levels frequently.
Adverse Reaction Data
Safety data from Phase II and III studies of single-agent VELCADE 1.3 mg/m2/dose twice weekly for 2 weeks followed by a 10-day rest period in 1163 patients with previously treated multiple myeloma (N=1008, not including the Phase III, VELCADE plus DOXIL(R) [doxorubicin HCl liposome injection] study) and previously treated mantle cell lymphoma (N=155) were integrated and tabulated. In these studies, the safety profile of VELCADE was similar in patients with multiple myeloma and mantle cell lymphoma.
In the integrated analysis, the most commonly reported adverse events were asthenic conditions (including fatigue, malaise and weakness) (64%), nausea (55%), diarrhea (52%), constipation (41%), peripheral neuropathy NEC (including peripheral sensory neuropathy and peripheral neuropathy aggravated) (39%), thrombocytopenia and appetite decreased (including anorexia) (each 36%), pyrexia (34%), vomiting (33%), anemia (29%), edema (23%), headache, paresthesia and dysesthesia and headache (each 22%), dyspnea (21%), cough and insomnia (each 20%), rash (18%), arthralgia (17%), neutropenia and dizziness (excluding vertigo) (each 17%), pain in limb and abdominal pain (each 15%), bone pain (14%), back pain and hypotension (each 13%), herpes zoster, nasopharyngitis, upper respiratory tract infection, myalgia and pneumonia (each 12%), muscle cramps (11%), and dehydration and anxiety (each 10%). Twenty percent (20%) of patients experienced at least 1 episode of =Grade 4 toxicity, most commonly thrombocytopenia (5%) and neutropenia (3%). A total of 50% of patients experienced serious adverse events (SAEs) during the studies. The most commonly reported SAEs included pneumonia (7%), pyrexia (6%), diarrhea (5%), vomiting (4%), and nausea, dehydration, dyspnea and thrombocytopenia (each 3%).
In the Phase 3 VELCADE + melphalan and prednisone study, the safety profile of VELCADE in combination with melphalan/prednisone is consistent with the known safety profiles of both VELCADE and melphalan/prednisone. The most commonly reported adverse events for VELCADE in combination with MP vs MP, respectively, were thrombocytopenia (52% vs 47%), neutropenia (49% vs 46%), nausea (48% vs 28%), peripheral neuropathy (47% vs 5%), diarrhea (46% vs 17%), anemia (43% vs 55%), constipation (37% vs 16%), neuralgia (36% vs 1%), leukopenia (33% vs 30%), vomiting (33% vs 16%), pyrexia (29% vs 19%), fatigue (29% vs 26%), lymphopenia (24% vs 17%), anorexia (23% vs 10%), asthenia (21% vs 18%), cough (21% vs 13%), insomnia (20% vs 13%), edema peripheral (20% vs 10%), rash (19% vs 7%), back pain (17% vs 18%), pneumonia (16% vs 11%), dizziness (16% vs 11%), dyspnea (15% vs 13%), headache (14% vs 10%), pain in extremity (14% vs 9%), abdominal pain (14% vs 7%), paresthesia (13% vs 4%), herpes zoster (13% vs 4%), bronchitis (13% vs 8%), hypokalemia (13% vs 7%), hypertension (13% vs 7%), abdominal pain upper (12% vs 9%), hypotension (12% vs 3%), dyspepsia (11% vs 7%), nasopharyngitis (11% vs 8%), bone pain (11% vs 10%), arthralgia (11% vs 15%) and pruritus (10% vs 5%).
