UPDATED RESULTS OF SONROTOCLAX + DEXAMETHASONE, AN ALL-ORAL TREATMENT, IN PATIENTS WITH T(11;14)-POSITIVE RELAPSED/REFRACTORY MULTIPLE MYELOMA
Notice bibliographique
Résumé
Despite the clinical efficacy of BCL2 inhibition in t(11;14)-positive multiple myeloma (MM), no BCL2-targeted treatments are approved. Sonrotoclax (BGB- 11417), a next-generation BCL2 inhibitor, is a more selective and pharmacologically potent inhibitor of BCL2 than venetoclax, with a shorter half-life and no drug accumulation. BGB-11417-105 (NCT04973605) is an ongoing phase 1b/2 study of sonrotoclax mono- or combination therapy in patients (pts) with t(11;14)-positive relapsed/refractory (R/R) MM. To assess safety and efficacy of sonrotoclax + dexamethasone (dex) in pts from BGB-11417-105. Eligible pts had R/R MM with centrally confirmed t(11;14) and received oral daily sonrotoclax (320 or 640 mg) and weekly dex (40 mg) until end of treatment. Adverse events (AEs) were graded by CTCAE v5.0, and efficacy was assessed by the investigator per IMWG criteria. As of January 20, 2025, 14 and 36 evaluable pts were enrolled in sonrotoclax 320- and 640-mg cohorts, respectively; median (range) follow-up was 6.2 months (2.6- 34.5) and 12.1 months (0.1-28.9), respectively. In the 320- vs 640-mg cohorts, respectively, median age (range) was 69.5 y (44-86) vs 69.0 y (48-80); 42.9% vs 52.8% were male; and 57.1% vs 75.0% were White. Pts had a median of 3 prior treatment lines in both the 320-mg (range, 1-7) and 640-mg (range, 1-12) cohorts; 78.6% and 66.7% of pts were refractory to 3 treatment classes, respectively. At data cutoff, 7 pts (50.0%) in the 320-mg cohort and 14 (38.9%) in the 640-mg cohort remained on treatment; progression was the most common reason for discontinuation (35.7% and 41.7%, respectively). The ORR (95% CI) was 64.3% (35.1%-87.2%) for 320 mg and 80.6% (64.0%-91.8%) for 640-mg, with VGPR or better rates (95% CI) of 35.7% (12.8%-64.9%) and 55.6% (38.1%-72.1%), respectively. The median time to response was 0.7 months in both cohorts. Median (95% CI) duration of response was 5.9 months (1.8-not estimable [NE]) in the 320-mg cohort and 12.2 months (8.3-18.9) in the 640-mg cohort. Median (95% CI) progression- free survival was 6.6 months (2.9-NE) in the 320-mg cohort and 13.3 months (9.0-19.6) in the 640-mg cohort. The safety profile was tolerable and manageable for both cohorts. The most common TEAEs were fatigue (35.7%) in the 320-mg cohort, and insomnia (38.9%) and diarrhea (38.9%, all grade 1 or 2) in the 640-mg cohort. Grade ≥3 TEAEs occurred in 5 pts (35.7%) in the 320-mg cohort and 17 pts (47.2%) in the 640-mg cohort; serious TEAEs occurred in 3 (21.4%) and 10 (27.8%), respectively. Grade ≥3 hematologic TEAEs occurred in 1 (7.1%) and 9 (25.0%) and grade ≥3 infections in 3 (21.4%) and 4 (11.1%) pts, respectively. Two pts (14.3%) in the 320-mg cohort and 2 (5.6%) in the 640-mg cohort died during the treatment-emergent portion of the study for reasons unrelated to sonrotoclax or dex (320-mg: pneumonia RSV and COVID-19; 640- mg: hypoventilation due to lung-involved progressive disease and metastatic pancreatic cancer). Four additional deaths occurred >30 days after the last 640-mg dose. The all-oral combination of sonrotoclax + dex continued to show a tolerable safety profile, with low rates of infection and hematologic toxicity, and promising efficacy, with an 81% ORR in the 640-mg cohort, in this t(11;14)-positive R/R MM population. The study is ongoing; additional treatment combinations with sonrotoclax are being investigated.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
