Study Endpoints

Primary Endpoints

Overall Response Rate (ORR) by Independent Review Committee (IRC) (Full Analysis Population)
Up to 48 weeks

ORR was determined according to the 2016 international myeloma working group (IMWG) response criteria by IRC. ORR was calculated as the percentage of participants with a confirmed partial response (PR) or better (that is \[i.e.\], PR, very good partial response \[VGPR\], complete response \[CR\] and stringent complete response \[sCR\]). Confidence intervals were based on the exact method.

Overall Response Rate by Independent Review Committee (Efficacy Population)
Up to 48 weeks

ORR was determined according to the 2016 IMWG response criteria by IRC. ORR was calculated as the percentage of participants with a confirmed PR or better (i.e., PR, VGPR, CR and sCR). Confidence intervals were based on the exact method. Efficacy Population comprised of first 130 intent-to-treat participants whether or not randomized treatment (frozen solution) was administered. Intent-to-treat Population comprised of all randomized participants whether or not randomized treatment was administered.

What is belantamab mafodotin frozen liquid?

Belantamab mafodotin frozen liquid is an investigational antibody-drug conjugate being developed by GSK plc for multiple myeloma. It is a frozen liquid formulation of belantamab mafodotin, studied in patients whose disease has progressed after prior treatment with an anti-CD38 antibody. It is in Phase 2 clinical development.

What is belantamab mafodotin frozen liquid used for?

Belantamab mafodotin frozen liquid is being studied for the treatment of multiple myeloma, specifically in patients who have failed prior treatment with an anti-CD38 antibody. The Phase 2 trial enrolled 221 participants with this condition across the United States, Australia, Canada, France, Germany, Italy, Spain, and the United Kingdom.

Who makes belantamab mafodotin frozen liquid?

Belantamab mafodotin frozen liquid is developed by GSK plc, which trades under the ticker GSK. GSK sponsored the Phase 2 study evaluating two doses of GSK2857916 in participants with multiple myeloma who had failed prior treatment with an anti-CD38 antibody.

What phase is belantamab mafodotin frozen liquid in?

Belantamab mafodotin frozen liquid is in Phase 2 clinical development. The single registered trial, NCT03525678, is a completed Phase 2 study that enrolled 221 participants. It is an investigational agent and has not been approved by the FDA for any indication based on the available development information.

What clinical trials is belantamab mafodotin frozen liquid in?

Belantamab mafodotin frozen liquid has been evaluated in one clinical trial, NCT03525678, titled a study to investigate the efficacy and safety of two doses of GSK2857916 in participants with multiple myeloma who have failed prior treatment with an anti-CD38 antibody. This Phase 2 trial is completed and enrolled 221 participants.

How does belantamab mafodotin frozen liquid work?

Belantamab mafodotin frozen liquid is an antibody-drug conjugate, or ADC, built on an antibody format. It combines a monoclonal antibody component with a cytotoxic payload to deliver treatment directly to target cells. The Phase 2 trial tested two dose levels of GSK2857916 in patients with relapsed or refractory multiple myeloma.
