F182112 versus standard care for relapsed or refractory multiple myeloma

Phase III Clinical Study of F182112 in Patients With Relapsed or Refractory Multiple Myeloma

This study will test whether F182112 works better than standard treatments for adults whose multiple myeloma has come back or stopped responding after prior therapies including a proteasome inhibitor, an immunomodulatory drug, and an anti-CD38 antibody.

What this trial studies

This is a multicenter, randomized, open-label, parallel-group Phase III trial comparing single-agent F182112 with investigator-selected standard-of-care regimens in adults with relapsed or refractory multiple myeloma. Eligible patients previously failed therapy containing at least one proteasome inhibitor, one immunomodulatory agent, and one anti-CD38 monoclonal antibody. Investigators pre-select a SOC comparator (for example PVd or SVd) before randomization, and participants are then randomized to F182112 or the selected SOC in an open-label design. The primary endpoint is progression-free survival adjudicated by an independent review committee using the 2016 IMWG criteria, with safety monitored throughout.

Who should consider this trial

Good fit: Adults (≥18 years) with relapsed or refractory multiple myeloma who have previously failed regimens containing at least one proteasome inhibitor, one immunomodulatory agent, and one anti-CD38 monoclonal antibody and who can give informed consent are the intended participants.

Not a fit: Patients with newly diagnosed myeloma, those who have not received the required prior classes of therapy, or those unable to attend participating centers or receive the selected SOC regimens are unlikely to benefit from enrollment.

Why it matters

Potential benefit: If successful, F182112 could offer a new treatment option that prolongs the time patients live without disease progression.

How similar studies have performed: Other novel agents and combination regimens have shown activity in heavily pretreated multiple myeloma, but F182112 itself has no published Phase III results to date.
