Brief summary
This study aims to investigate the safety and tolerability of Hydroxychloroquine in combination with Carfilzomib and Dexamethasone for multiple myeloma. Who is it for? You may be eligible for this study if you are a patient aged over 18 years who has a diagnosis of relapsed or refractory multiple myeloma patients with a partial response or less after 2 cycles of Carfilzomib treatment. Study details Participants will undergo 2 cycles of once-weekly Carfilzomib and Dexamethasone as per the standard of care. If participants are deemed to have a partial response or less by clinician assessment, Hydroxycholoroquine treatment will be initiated for the next 10 cycles alongside continuing Carfilzomib and Dexamethasone. Data on adverse events, toxicities and dose limiting toxicities as well as disease response will be collected. It is hoped that data from this study will help to inform the role of Hydroxychloroquine in treating multiple myeloma.
Interventions
All study participants will initially receive 2 cycles of once-weekly intravenous Carfilzomib and oral Dexamethasone as per the standard of care. During the rest period of Cycle 2, disease response assessment will be performed according to the International Myeloma Working Group (IMWG) Criteria for Response Assessment. Each cycle is 28 days. Participants who achieve a very good partial response (VGPR) or above will continue receiving once-weekly Carfilzomib and Dexamethasone (without Hydroxychloroquine), as per the standard of care and at the discretion of the treating physician. Participants who achieve a partial response (PR) or below will undergo additional assessments before beginning treatment with oral Hydroxychloroquine and continued once-weekly Carfilzomib and Dexamethasone. The dose of Hydroxychloroquine that a participant will receive is dependent on the stage of dose-escalation: Level -1, 200 mg every other day; level 1 (starting dose) 200 mg once daily; level 2, 200 mg twice daily; level 3, 200 mg three times daily; level 4, 400 mg twice daily. The duration of combined treatment will be a maximum of 10 cycles. Carfilzomib 20 mg/m2 will be given as the starting dose on Cycle 1 Day 1, followed by escalation to 70 mg/m2 for all subsequent doses, if tolerated. Participants will continue to receive Carfilzomib at 70 mg/m2 until treatment discontinuation. Strategies to monitor adherence include checking patient records, medication diary and counting hydroxychloroquine tablets at the end of each cycle.
