For multiple myeloma patients with the 11;14 translocation who respond poorly to initial induction, BCL-2 inhibition is becoming a crucial targeted strategy. New drug combinations are showing high efficacy, addressing a key unmet need and suggesting this approach will be central to improving outcomes for this specific genetic subset.

The field of multiple myeloma has transformed from having few treatments to an abundance of effective drugs. The primary clinical challenge is no longer finding a therapy that works, but rather determining the optimal sequence and combination of available options, highlighting a unique form of market maturity.
The treatment backbone for Ph+ ALL is shifting away from intensive chemotherapy like hyper-CVAD. Chemotherapy-free regimens combining blinatumomab with a TKI (preferably ponatinib) are becoming the new standard, showing outcomes that are at least as good as, and likely better than, traditional chemotherapy.
Combining Bellemaf with VRd induction for newly diagnosed, transplant-ineligible myeloma yields 100% response rates. This potent efficacy is driving its adoption in earlier treatment lines, with the clinical focus shifting to proactively managing its known ocular toxicities through dose adjustments and holds.
The development of agents targeting specific mutations like CALR and JAK2V617F marks a move away from the "one size fits all" JAK inhibitor approach. This enables a more personalized, molecularly-driven treatment strategy that was previously not possible for MPN patients.
The DAYBREAK pivotal study focuses on third-line plus patients who have already failed both BTK and BCL2 inhibitors. By enrolling this high unmet need population, particularly those resistant to the newest non-covalent inhibitors, Neurix aims for an accelerated regulatory approval to get its drug to market faster.
Despite strong single-agent trial results, experts believe the field is shifting away from continuous monotherapy. The most significant future impact for pirtobrutinib will likely be as a backbone of fixed-duration combination therapies with drugs like venetoclax, aiming for deeper remissions without indefinite treatment.
An expert who initially viewed CELMoDs as incremental improvements now considers them fundamentally different. The new litmus test for future myeloma trials will be tracking prior patient exposure to CELMoDs like iberdomide, just as they track prior IMiD exposure today, cementing their status as a distinct therapeutic category.
Using a BCMA bispecific antibody first can exhaust a patient's T-cells or cause tumors to lose the BCMA target, rendering a subsequent BCMA-targeted CAR-T therapy ineffective. The optimal sequence is CAR-T first, which preserves T-cell function and BCMA expression, leaving bispecifics as a viable later-line option.
Recent non-inferiority trials affirm that fixed-duration combination therapies are viable alternatives to continuous BTK inhibitors. However, clinicians must look beyond the headline conclusion, as numerical data can show slightly worse progression-free survival for high-risk subgroups within the acceptable non-inferiority margin, complicating treatment decisions.
A new class of oral drugs, BCL6 degraders, are demonstrating complete remissions as a single agent in heavily pretreated aggressive lymphoma patients. This activity was surprising, as they were initially expected to require combination therapy to be effective, signaling a promising new non-cell surface targeting mechanism.
