Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT05920876
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Relapsed or Refractory Multiple Myeloma
Additional Details

Multiple myeloma (MM) is a malignant disease with abnormal proliferation of clonal plasma cell, which is often accompanied by multiple osteolytic damage, hypercalcemia, anemia, and kidney damage. QLS32015 is a humanized immunoglobulin gamma-1 (IgG1) type bispecific antibody targeting G protein-coupled receptor family C group 5-member D (GPRC5D) and cluster of differentiation 3 (CD3). The study consists 3 periods: screening phase, treatment phase and a post-treatment follow-up phase. The study will evaluate safety, tolerability, pharmacokinetics and preliminary antitumor activity of QLS32015 administered to participants with relapsed or refractory multiple myeloma. Total duration of study is up to 2 years.
