Data from a large phase III trial (Myeloma XI) were examined to determine the relationship between MRD status, PFS, and OS in post-ASCT patients randomly assigned to lenalidomide maintenance or no maintenance at 3 months after ASCT. At ASCT + 3 and ASCT + 9, MRD-negative status was associated with improved PFS and OS. Sustained MRD negativity from ASCT + 3 to ASCT + 9 or the conversion to MRD negativity by ASCT + 9 was associated with the longest PFS/OS.

In an editorial accompanying the final results of the TOURMALINE-MM1 study, Drs. D’Souza and Lonial question whether overall survival (OS) is “still the gold standard for demonstrating the value of a novel agent in phase III trials early in the disease course given the current treatment landscape.”

According to the results of a study published in Annals of Hematology, two novel analytical approaches for detecting malignant plasma cell clones appear to accurately indicate the course of multiple myeloma (MM) and may be valuable for monitoring patients with serologically nontrackable disease.

Jacob Laubach, MD, at the Dana-Farber Cancer Institute provides a summary of the most recent update from the GRIFFIN trial, assessing daratumumab plus lenalidomide, bortezomib, and dexamethasone in newly diagnosed multiple myeloma patients. After 24 months of maintenance therapy or treatment discontinuation (median follow-up of 38.6 months), the rate of stringent complete response (sCR) was 66% in the D-RVd treatment arm versus 47.4% in the RVd treatment arm. At the time of data collection, median PFS had not been reached in either arm but is trending towards favoring D-RVd versus RVd. The estimated 36-month PFS rate was 88.9% for D-RVd and 81.2% for RVd.

Publication: The LancetDesign: Open-label, single-arm study of 157 patients who had undergone a median of six previous lines of therapy and who received at least one dose of teclistamab; 40 patients received the recommended phase II dose of teclistamabResults: Of the 40 receiving the phase II dose, 58% achieved a very good partial response or better; 40% achieved a complete response or better

Source: Blood AdvancesKey Points: In a cohort of 154 patients with NHL or MM receiving CAR T-cells, clonal hematopoiesis of indeterminate potential (CHIP) was present in 48%. Although associated with worse prognosis in these patients receiving autologous transplantation, no such association was seen in these patients receiving CAR T. Instead, the authors saw increased rates of complete response and cytokine release syndrome severity in the younger than 60 population. However, there was no difference in progression-free or overall survival, regardless of age. Design: Cohort review of 154 patients with NHL or MM receiving CAR T-cells
