European Commission Approves Darzalex®▼ (daratumumab) in Combination with Bortezomib, Thalidomide and Dexamethasone (VTd) for Patients with Newly Diagnosed Multiple Myeloma Who Are Transplant Eligible

The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that the European Commission (EC) has granted marketing authorisation for Darzalex® (daratumumab) in combination with bortezomib, thalidomide and dexamethasone (VTd) for the treatment of patients with newly diagnosed multiple myeloma who are eligible for autologous stem cell transplant (ASCT). This approval is based on results from Part one of the Phase 3 CASSIOPEIA (MMY3006) study, published in The Lancet[5] in June 2019 and presented at the 2019 American Society of Clinical Oncology (ASCO) Meeting.

“The effectiveness of first-line treatment is critical to maximise time until relapse. So, we asked ourselves, can we improve the standard of care that is bortezomib, thalidomide and dexamethasone (VTd) to provide patients with valuable extra time?” said Philippe Moreau, M.D., principal investigator and Head of the Haematology Department at the University Hospital of Nantes, France. “The CASSIOPEIA study answered that question definitively, demonstrating that the addition of daratumumab in combination with VTd can lead to very deep remissions and also prolong PFS. I’m pleased to see the European Commission have recognised this as well.”

“Today’s approval marks the first opportunity for newly diagnosed, transplant eligible patients to be treated with a monoclonal antibody, and the first new treatment for this patient population in over six years,” said Dr Patrick Laroche, Haematology Therapy Area Lead, Europe, Middle East and Africa (EMEA), Janssen-Cilag. “We are thrilled that newly diagnosed patients with multiple myeloma and their doctors will have a long-awaited additional frontline therapy.”

The Phase 3 CASSIOPEIA trial is a two-part study. Results from this first part of the trial showed that after consolidation, the stringent complete response (sCR) rate was significantly higher in the daratumumab-VTd arm (29 percent) compared to VTd alone (20 percent) (Odds Ratio [OR] = 1.60; 95 percent confidence interval [CI], 1.21-2.12; P<0.0010).2 At a median follow-up of 18.8 months, PFS was significantly improved in the daratumumab-VTd group compared to VTd alone (Hazard Ratio [HR] = 0.47; 95 percent CI, 0.33-0.67; P<0.0001), and the median PFS was not reached in either arm.2 The addition of daratumumab to VTd resulted in an 18-month PFS rate of 93 percent compared to 85 percent for VTd alone.2

The most common (≥10%) Grade 3/4 treatment-emergent adverse events (TEAEs) for daratumumab-VTd and VTd, respectively, were neutropenia (28 percent vs. 15 percent), lymphopenia (17 percent vs. 10 percent), stomatitis (13 percent vs. 16 percent) and thrombocytopenia (11 percent vs. 7 percent).2 In the daratumumab-VTd combination arm, infusion-related reactions occurred in 35 percent of patients.2

“This approval represents our commitment to investigate daratumumab in earlier disease stages of multiple myeloma and to develop more effective frontline treatment options for newly diagnosed patients who are eligible for transplantation,” adds Craig Tendler, M.D., Vice President, Clinical Development and Global Medical Affairs, Oncology, Janssen Research & Development, LLC.

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...
