The Safety and Efficacy of Pomalidomide in Combination With Cyclophosphamide and Dexamethasone (PCD) in the Transplant-ineligible Patients With Relapsed and/or Refractory Multiple Myeloma (MM) (PORYOU)

February 19, 2020 updated by: Ho Sup Lee, Kosin University Gospel Hospital

The Safety and Efficacy of Pomalidomide in Combination With Cyclophosphamide and Dexamethasone (PCD) in the Transplant-ineligible Patients With Relapsed and/or Refractory Multiple Myeloma (MM) Who Had Lenalidomide Plus Dexamethasone (LD) Following Frontline Bortezomib Combined Chemotherapy, Open-labeled, Multicenter Phase II Study

In Korea, VMP is most commonly used as frontline treatment in patients with newly diagnosed MM who were ineligible for high-dose therapy. Recently National Insurance began to reimburse the second-line LD when the bortezomib-containing treatment failed to salvage the patients. Patients who have relapsed MM after exposure to the above agents and have progressive disease have a short life expectancy. Third-line therapy is needed for retrieving the patients hereafter. And substantial proportion of patients will attain an advanced age. To examine if time to disease progression is maintained and tolerability is improved with lower dexamethasone dose, the dose of dexamethasone is reduced when at least a minimal response is achieved after 3 months of treatment with the initial dose. Three months later (6 months after the initial treatment), the response remains in stable disease, 2nd dose reduction (dexamethasone 10mg or prednisone 50mg) will be carried out.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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

18 years and older (Adult, Older Adult)
