Phase 2, Single-Arm, Non-Inferiority Study Of Limited-Duration Teclistamab For Relapsed Refractory Multiple Myeloma

Description

This is a single-arm, non-inferiority study in which patients who have achieved a very good partial response (VGPR) or better, according to International Myeloma Working Group (IMWG) response criteria, following 6 to 9 months of treatment with teclistamab, a B-cell maturation antigen (BCMA)-directed T-cell engager (anti-BCMAxCD3 bispecific antibody), will be offered monitored drug discontinuation. Teclistamab is typically dosed on a regular schedule (every 1-4 weeks) indefinitely until disease progression ("continuous therapy"). Here, a limited-duration regimen will be studied in which patients achieving ≥VGPR after 6-9 months of standard teclistamab dosing will discontinue therapy and resume if laboratory or clinical parameters suggest early disease progression ("limited-duration therapy"). Patients will enter the clinical trial protocol after completing 6-9 months of standard teclistamab monotherapy and achieving ≥VGPR. The study's hypothesis is that the failure probability six month

Trial Eligibility

Inclusion Criteria: * Participants must be age ≥18 and able to give written, informed consent. * Participants must have initiated teclistamab (first full dose) 6-9 months prior to enrollment and received an average teclistamab dose of at least 1.5 mg/kg/month since the date of the first 1.5 mg/kg dose. * Participants must have received a teclistamab dose within 4 weeks prior to enrollment. * Participants must have had measurable disease according to IMWG criteria within 1 month prior to teclistamab initiation or first full teclistamab dose * Participants must have achieved a confirmed VGPR or better to teclistamab therapy at any assessment prior to enrollment and have ongoing response (i.e., no disease progression) at time of enrollment per IMWG consensus criteria (Appendix 14.3). * Prior to initiating teclistamab, participants must have received therapy with a proteasome inhibitor, thalidomide analog (lenalidomide or pomalidomide), and an anti-CD38 antibody and meet one of the following criteria: 1. ≥3 prior lines of therapy (with lines-of-therapy delineated according to IWMG guidelines) 2. Refractory to both a proteasome inhibitor and a thalidomide analog. * Participants must have had an ECOG performance status of 0-2 at time of teclistamab initiation; in addition, ECOG performance status must be 0-1 at time of enrollment. * Participants must not have known diagnoses of systemic amyloidosis or POEMS syndrome.
