A Study to Learn About the Study Medicine (Maplirpacept) in People With Advanced Non-Hodgkin Lymphoma or Multiple Myeloma in China
Study Details
Study Description
Brief Summary
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.

Detailed Description
The study is composed of 2 parts. In Part A, approximately 3-6 participants are expected to be enrolled to confirm the tolerability in Chinese participants. If deemed safe, the enrollment of Part B will proceed to include a total of approximately 9 participants in the study to continue to evaluate the pharmacokinetics, safety and preliminary efficacy of single agent PF-07901801 (Maplirpacept).

Outcome Measures
Primary Outcome Measures
- Number of Participants With Dose-Limiting Toxicity (DLT) [Cycle 1：up to 21 days]
Part A only. To characterize the dose limiting toxicities (DLTs) of Maplirpacept.
- Single-dose Cmax [0, 1, 2, 4, 24, 72 hours post-dose up to Day 8]
Maximum Observed Plasma Concentration
- Single-dose AUClast [0, 1, 2, 4, 24, 72 hours post-dose up to Day 8]
Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast)
- Single-dose AUCtau [0, 1, 2, 4, 24, 72 hours post-dose up to Day 8]
Area under the concentration curve from time 0 to end of dosing interval (AUCtau), where dosing interval was 1 week.
Secondary Outcome Measures
- Number of Participants With Adverse Events (AEs) by type, frequency, severity (as graded by NCI CTCAE version 5.0), timing, seriousness and relationship to study treatment [Baseline up to 28 days after the last dose of study drug]
An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Counts of participants who had treatment-emergent adverse events (TEAEs), defined as newly occurring or worsening after first dose. Participants with multiple occurrences of an AE within a category were counted once within the category. Relatedness to study drug was assessed by the investigator.
- Number of Participants With Clinically Significant Change From Baseline in Laboratory Abnormalities by type, frequency, severity (as graded by NCI CTCAE version 5.0), and timing [Baseline up to 28 days after the last dose of study drug]
Laboratory parameters included: hematology, blood chemistry and coagulation. Clinical significance of laboratory parameters was determined at the investigator's discretion.
- Single-dose Tmax (Time to Reach Maximum Observed Plasma Concentration) [0, 1, 2, 4, 24, 72 hours post-dose up to Day8]
