A Study of Pomadomide in Combination With Rituximab and Methotrexate for Newly-diagnosed Primary Central Nervous System Lymphoma

August 13, 2024 updated by: Second Affiliated Hospital, School of Medicine, Zhejiang University

The Safety and Efficacy of Pomadomide in Combination With Rituximab and Methotrexate for Newly-diagnosed Primary Central Nervous System Lymphoma : A Prospective, Multicenter, Phase I/II Study

This is a prospective, multicenter, single-arm, open Phase Ib/II clinical study to explore the safety and efficacy of pomadomide in combination with rituximab and methotrexate (RPM) in newly diagnosed primary central nervous system lymphoma (PCNSL) subjects. The Phase I study is a dose escalation study, in which rituximab and methotrexate are fixed doses, and pomadomide is set into 3 dose groups: 3mg/d, 4mg/d and 5mg/d. In strict accordance with the "3+3" dose escalation principle, 3-6 subjects are to be recruited in each dose group, and each subject is to be observed for 1 cycle after treatment to determine MTD. Phase II study: RP2D is planned to be determined based on the Phase Ib study, with an additional 25 active participants enrolled to further evaluate efficacy and safety. Subjects with initial treatment of PCNSL who met the inclusion/exclusion criteria were screened, and after signing the informed consent letter, they received 4 courses of PRM regimen. The patients achieving CR or PR were consolidated by autologous transplantation consolidation regimen or the original regimen for 2 courses, and then were given pomadomide maintenance therapy for 12 cycles. Follow-ups should be taken up to the first 3 years.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No
