Clinical Trial Summary

This is a Phase 1/2, multicenter, open label, dose-escalation, nonrandomized study to evaluate the safety, pharmacodynamics, and efficacy of a 60-minute infusion of carfilzomib for patients with progressive multiple myeloma.

Description:

This is a Phase 1/2, multicenter, open label, dose-escalation, nonrandomized study to evaluate the safety, pharmacodynamics, and efficacy of a 60-minute infusion of carfilzomib for patients with progressive multiple myeloma.

The study will consist of a screening period, followed by a treatment period of up to eight 28-day treatment cycles, followed by a period of maintenance treatment. Subjects are to be treated until disease progression.

Postmenopausal females (> 45 years old and without menses for > 1 year) and surgically sterilized females are exempt from a pregnancy test

15. Known hepatitis B or C virus infection (except for patients with HBV receiving and responding to HBV antiviral therapy: these patients are allowed)

1. Adequately treated basal cell or squamous cell skin cancer

2. Carcinoma in situ of the cervix

3. Prostate cancer < Gleason score 6 with stable prostate-specific antigen (PSA) over 12 months

4. Breast carcinoma in situ with full surgical resection

5. Treated medullary or papillary thyroid cancer

Intervention

Drug:
• Carfilzomib and Dexamethasone
Phase 1: Carfilzomib will be administered at an escalating dose by cohort as 60-minute IV infusion on Days 1, 2, 8, 9, 15, and 16 of a 28-day cycle. On Cycle 1 Days 1 and 2, carfilzomib will be given at 20 mg/m^2. For all subsequent doses, carfilzomib will be administered at the dose assigned to the cohort (56, 70, or 88 mg/m^2). Dexamethasone (8 mg IV or PO) will be administered prior to carfilzomib on Days 1, 2, 8, 9, 15, and 16. Phase 2: Carfilzomib will be administered at the MTD determined in phase 1. Maintenance: From Cycle 9 onward, carfilzomib and dexamethasone will be administered in the same fashion as during the previous treatment cycle, but only on days 1, 2, 15, and 16.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Relationship of 60-minute infusion of carflizomib with pharmacodynamic markers		weekly for 2 months
Primary	Establish maximum tolerated dose (MTD)	Maximum tolerated dose will be established by the number of dose limiting toxicities and the overall safety and tolerability of the study drug.; Safety and tolerability will be determined by the following: incidence and frequency of adverse events throughout the study; clinical laboratory test results at study visits; vital signs measurements at each study visits; medical history and physical examination findings; ECOG performance status at study visits; concomitant medication usage throughout the study	monthly, up to 24 months
Secondary	Establish efficacy as assessed by the overall response rate	Response rate will be determined by the following: SPEP, UPEP, and quantification of immunoglobulins and immunofixation; bone marrow aspirates and biopsies to confirm CR; roentgenographic skeletal survey; Response rate will be assessed by the following: Clinical benefit response rate; Progression-free survival; Time to progression; Duration of response; Overall survival; Pharmacodynamics	monthly, up to 24 months
