Frequently asked questions about Acasunlimab

What is Acasunlimab used for?

Acasunlimab is an investigational monoclonal antibody being developed for the treatment of solid tumors, including PD-L1-positive locally advanced unresectable Stage IIIB/C or metastatic non-small cell lung cancer (NSCLC) and cutaneous melanoma. It is also being studied in metastatic NSCLC and other solid tumor types.

Who is developing Acasunlimab?

Acasunlimab is being developed by Genmab A/S, a biotechnology company traded on the Nasdaq under the ticker GMAB. The company is conducting clinical trials to evaluate the drug's safety and efficacy in patients with various advanced solid malignancies.

What phase is Acasunlimab in?

Acasunlimab is currently in Phase 2 clinical development. It has completed a Phase 1 trial and is being evaluated in Phase 1/2 and Phase 2 studies. A Phase 3 trial has also been initiated, though the drug remains investigational and is not yet approved.

What clinical trials is Acasunlimab in?

Acasunlimab is being studied in several clinical trials, including NCT03917381, a Phase 1/2 safety trial in patients with malignant solid tumors; NCT04937153, a completed Phase 1 study; NCT05117242, a Phase 2 trial in metastatic NSCLC; and NCT06635824, a Phase 3 trial evaluating the drug in combination with pembrolizumab.

Is Acasunlimab the same as GEN1046?

Yes, Acasunlimab is also known as GEN1046. Clinical trial records refer to the drug by both names, with GEN1046 used in earlier studies and Acasunlimab appearing in more recent trial titles, such as the Phase 3 ABBIL1TY NSCLC-06 study.

How does Acasunlimab work?

Acasunlimab is a monoclonal antibody, a type of targeted therapy that binds to specific proteins involved in cancer growth. As an antibody, it is designed to interfere with tumor cell signaling or immune system interactions, though its precise molecular target has not been specified in available information.
