Multiple Myeloma Clinical Trial
Official title:
AN OPEN-LABEL, PHASE 1 STUDY EVALUATING THE PHARMACOKINETICS, SAFETY AND ANTI-TUMOR ACTIVITY OF PF-07901801 (TTI-622) MONOTHERAPY IN CHINESE PARTICIPANTS WITH ADVANCED HEMATOLOGIC MALIGNANCIES
The purpose of this study is to learn about the safety and what the body does to the medicine (Maplirpacept) when taken for the treatment of non-Hodgkin lymphoma or multiple myeloma. Non-Hodgkin lymphoma is any of a large group of cancers of lymphocytes (white blood cells). Multiple myeloma is a type of cancer that begins in plasma cells (white blood cells that produce antibodies). This study is seeking participants who: - have non-Hodgkin lymphoma or multiple myeloma. - have worsened with (or lack of improvement to) a standard treatment taken before. - have relatively normal functioning organs. All participants in this study will receive Maplirpacept as an intravenous (IV) infusion (given directly into a vein) at the study clinic every week. Participants will continue to receive Maplirpacept until: - the cancer worsens. - some serious side effects show up. - the participants do not wish to take the study medicine any more. The experiences of the people receiving the study medicine will be collected. This will help to understand if the study medicine Maplirpacept, is safe and can be given to Chinese people.
