Multiple myeloma (MM) is still an uncurable disease. Chimeric antigen receptor (CAR) T cells directed to tumor necrosis factor receptor superfamily member 17, also known as BCMA, have transformed the field, with high response rate and durable remissions, but the access to this therapy is limited by multiple factors.
Multiple myeloma (MM) stands as the second most common hematologic malignancy. Proteasome inhibitors are effective in MM, but many patients develop resistance, which is thought to be caused by mutations in the PSMB5 gene.
By a unanimous 12-0 vote, the U.S. FDA’s Oncologic Drugs Advisory Committee concluded that new evidence support the use of minimal residual disease (MRD) as an accelerated approval endpoint in multiple myeloma (MM) clinical trials. The FDA will now consider the recommendation, which, if incorporated into future studies, could dramatically shorten some drug developer timelines and offer more options for treating the aggressive bone marrow cancer.
The U.S. FDA thinks using minimal residual disease as an endpoint for accelerated approval in new therapies to treat multiple myeloma (MM) might just be an idea whose time has come. The FDA now wants to know what its Oncologic Drugs Advisory Committee thinks about it, so the agency has convened a meeting of the committee for a deep dive into the subject on April 12.
DXC-006 (Hangzhou DAC Biotechnology Co. Ltd.) is an antibody-drug conjugate (ADC) that targets CD56, a molecule involved in cell-cell adhesion and cell-matrix adhesion that is overexpressed in neuroblastoma, small-cell lung cancer and multiple myeloma, but less frequently expressed in normal tissues. DXC-006 consists of an anti-CD56 antibody (DXA-006) linked to the topoisomerase 1 (TOP1) inhibitor CPT-116 through a linker.
Following the U.S. FDA’s expansion of competing BCMA-targeting CAR T therapy Abecma (idecabtagene vicleucel) to include third-line and later treatment in multiple myeloma (MM) patients, the agency cleared Carvykti (ciltacabtagene autoleucel) from Legend Biotech Corp. and Johnson & Johnson’s Janssen unit for use in MM patients as early as second-line treatment. The label, which RBC Capital Markets analyst Leonid Timashev called a “best-case scenario,” includes no notable updates to the black box warning and should help accelerate and expand Carvykti’s update in the U.S., with 2024 revenues expected to top $950 million.
Mixed opinions from the U.S. FDA’s Oncology Drugs Advisory Committee last month didn’t stop the agency from green-lighting an expanded label for Abecma (idecabtagene vicleucel) to include adults with relapsed or refractory multiple myeloma (r/r MM) after two or more prior lines of therapy including an immunomodulatory agent, a proteasome inhibitor and an anti-CD38 monoclonal antibody.
About 90% of patients with multiple myeloma (MM) develop severe bone disease, known as myeloma bone disease (MBD). This occurs due to the ability of MM cells to disrupt bone homeostasis, leading to excessive bone resorption. Some current treatments are effective for treating MBD, but they are associated with undesired adverse events.
Previous research has shown that adenosine impairs antitumor immunity, and high levels of adenosine and CD73 have been associated with poor prognosis in cancer.
The U.S. FDA’s Oncology Drugs Advisory Committee, in two separate sessions, took up the matters of Carvykti (ciltacabtagene autoleucel) from Johnson & Johnson and the Bristol Myers Squibb Co. product Abecma (idecabtagene vicleucel) – specifically, whether the benefits of each CAR T therapy outweigh the risks in relapsed or refractory multiple myeloma (MM).
