ANZCTR - Registration

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary

Brief summary

The drug that will be investigated in the study is an antibody, GEN3014. Since this is the first study of GEN3014 in humans, the main purpose is to evaluate safety. Besides safety, the study will determine the recommended GEN3014 dose to be tested in a larger group of participants and assess preliminary clinical activity of GEN3014. GEN3014 will be studied in relapsed or refractory multiple myeloma (also known as RRMM) and other blood cancers. The study consists of 3 parts:

1. The Dose Escalation will test increasing doses of GEN3014 to find a safe dose level to be tested in the other two parts.
2. Expansion Part A will further test the GEN3014 dose determined from the Dose Escalation Part.
3. Expansion Part B will compare intravenous (IV) GEN3014 with the subcutaneous (SC) daratumumab in ex-US countries.

Participants will receive either GEN3014 or daratumumab; none will be given placebo. The study duration will be different for the individual participants. Overall, the study may be ongoing up to 5 years after the last participant's first treatment.
