Summary

This phase I trial studies the side effects and best dose of selinexor and carfilzomib when given together with dexamethasone in treating patients with multiple myeloma that has returned or does not respond to treatment. Drugs used in chemotherapy, such as selinexor and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Carfilzomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving selinexor, carfilzomib, and dexamethasone may be a better treatment for multiple myeloma.

Clinical Details

Official title: A Phase I Study of the Combination of a Selective Inhibitor of Nuclear Export (SINE), Selinexor With Carfilzomib and Dexamethasone in Patients With Relapsed or Relapsed/Refractory Multiple Myeloma

Study design: Endpoint Classification: Safety Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: MTD and RP2D selinexor, carfilzomib, and dexamethasone defined as the dose level below the dose in which greater than or equal to 2 out of 6 patients experience dose limiting toxicity

Secondary outcome:

Incidence of toxicities related to the combination of selinexor and carfilzomib assessed using NCI CTCAE version 4.0

Efficacy as measured by stable disease or better (including MR, partial response, very good partial response, complete response and stringent complete response) according to IMWG criteria

Incidence of toxicities assessed using NCI CTCAE version 4.0

Detailed description: PRIMARY OBJECTIVES: I. Determine the maximum tolerated dose (MTD) and the recommended phase II dose (RP2D) of the combination of selinexor, carfilzomib, and dexamethasone in relapsed and relapsed/refractory multiple myeloma. SECONDARY OBJECTIVES: I. Determine safety and tolerability. II. Determine the efficacy, as measured by the rates of stable disease or better (including minimal response, partial response, very good partial response, complete response, and stringent complete response). III. To perform pharmacokinetic studies at first cycle for each dose level for both selinexor and carfilzomib, and compare the results to those from their respective single arm trials. TERTIARY OBJECTIVES: I. To perform an exploratory evaluation of pharmacodynamics. II. To study the effects of treatment on exportin 1 (XPO1) expression in peripheral blood mononuclear cells (PBMCs) at day 1 and day 15 of cycle 1, and at the time of progression/relapse. III. To assess clinical response in standard and high-risk prognostic subgroups based on cytogenetics and gene expression profiling. OUTLINE: This is a dose-escalation study of selinexor and carfilzomib. Patients receive selinexor orally (PO) once daily (QD) on days 1, 3, 8, 10, 15, and 17, carfilzomib intravenously (IV) over 30 minutes on days 1, 2, 8, 9, 15, and 16, and dexamethasone PO QD or IV on days 1, 2, 8, 9, 15, 16, 22, and 23. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days and then every 3 months for 2 years.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Written informed consent in accordance with federal, local, and institutional

guidelines

- Eastern Cooperative Oncology Group (ECOG) performance status of 0-2

- Diagnosis of multiple myeloma as per International Myeloma Working Group (IMWG)

uniform criteria

- Measurable disease by IMWG as defined by at least one of the following:

- Serum M-protein >= 0. 5 g/dL

- Urine M-protein >= 200 mg in a 24-hour collection

- Serum free light chain level >= 10 mg/dL provided the free light chain ratio is

abnormal

- Measurable plasmacytoma; if plasmacytoma measurement is the only measurable

disease, subject eligibility must be reviewed with lead principal investigator (PI) prior to signing consent

- Relapsed/refractory multiple myeloma with progressive disease at study entry

- Subjects must have been treated with at least 2 prior therapies including a

proteasome inhibitor and a cereblon-binding agent

- Subjects who are refractory to carfilzomib may enroll throughout the trial;

carfilzomib refractory status is defined by IMWG criteria: disease that is nonresponsive while on salvage therapy, or progresses within 60 days of last therapy in patients who have achieved minimal response (MR) or better at some point previously before then progressing in their disease course

- In the expansion cohort of the study, enrollment will be limited to patients

meeting carfilzomib refractory status

- Ability to adhere with the study visit schedule and other protocol procedures

indicated per institutional guidelines but screening hemoglobin should be independent of red blood cell transfusion for at least 3 days prior to cycle 1 day 1

- Platelet count >= 50,000mm^3; platelet count should be independent of transfusions

for at least 14 days for eligibility

- Total bilirubin =< 2 times the upper limit of normal (ULN) (except patients with

Gilbert's syndrome who must have a total bilirubin of < 3 times ULN)

- Alanine aminotransferase (ALT) =< 2. 5 times ULN; in the case of known (radiological

and/or biopsy documented) liver metastasis, ALT =< 2. 5 times ULN is acceptable
