研究概览
简要总结
The purpose of this study is to see if the study drug, called Vactosertib, is safe and determine what the best dose is to treat future patients when given in combination with pomalidomide (POM). The study will also look to see if it has any effect on multiple myeloma, when given in combination with POM.
详细描述
Primary Objective
- To determine the maximum tolerated dose (MTD) or maximum tested dose level of Vactosertib given in combination with pomalidomide (POM) for the treatment of relapsed or relapsed or refractory multiple myeloma (RRMM)
- To characterize the safety and tolerability profile of Vactosertib in combination with POM at the MTD
Secondary Objectives
To evaluate the activity of the combination of Vactosertib/POM regimen in terms of:
- Overall response rate (complete response [CR] + very good partial response [VGPR] +partial response [PR]) and clinical benefit rate (CR + VGPR + PR + minimal response [MR]) based on International Myeloma Working Group (IMWG) defined response criteria and the duration of response (DOR) in RRMM patients.
- Progression-free survival (PFS) and PFS at 6 months (PFS-6)

- •Clinical Laboratory Inclusion Criteria: The following laboratory results must be met within 14 days (or as stipulated) prior to study drug (treatment) administration:
- •Absolute neutrophil count (ANC) ≥ 1000 cells/μl (growth factor cannot be used within the previous 5 days)
- •Platelet count ≥ 50,000/μl (without platelet transfusion in the previous 5 days)
- •Aspartate aminotransferase (AST/SGOT) and Alanine aminotransferase (ALT/SGPT) ≤ 3.0 x upper limit of normal (ULN)
- •Serum total bilirubin ≤ 2.0 mg/dL or >3.0 x ULN for subjects with hereditary benign hyperbilirubinemia
- •Creatinine clearance ≥ 30 ml/min (calculated by the Cockcroft-Gault Equation or per 24 hour urine collection)
- •Serum calcium (corrected for albumin) level at or below the ULN range (treatment of hypercalcemia is allowed and subject may enroll if hypercalcemia returns to normal range with standard treatment).
- •Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test prior to initiation of the study treatment with Vactosertib/POM. The test must have a sensitivity of at least 50 mIU/mL. Study participants who are FCBP must either commit to continued abstinence from heterosexual intercourse or begin two acceptable methods of birth control, one highly effective method and one additional effective method at the same time, at least 28 days before she starts taking POM through 30 days after the last dose of POM and 60 days after the last dose of Vactosertib. FCBP must also agree to ongoing pregnancy testing during the entire duration of treatment. Men must agree to use a latex or synthetic condom during sexual contact with a FCBP even if they have had a vasectomy from the time of signing the informed consent form through 60 days after the last dose of POM or Vactosertib. These same patients must not donate sperm. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure. All patients enrolled into this trial, must agree to be registered in and must comply with all requirements of the Pomalidomide Risk Evaluation and Mitigation Strategy (POM REMS™) program.
排除标准

- •Plasma Cell Leukemia
- •Patients with solitary plasmacytoma

- •Prior treatment with pomalidomide.
- •Subjects with active malignancy and/or cancer history that may confound the assessment of the study endpoints. Patients with a past cancer history (within 2 years of entry) with substantial potential for recurrence and/or ongoing active malignancy must be discussed with the trial collaborator, MedPacto Inc., before study entry. Patients with the following neoplastic diagnoses are eligible: non-melanoma skin cancer, carcinoma in situ (including superficial bladder cancer), cervical intraepithelial neoplasia, and organ-confined prostate cancer with no evidence of progressive disease
- •Any > grade 1 (according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTC AE) v.4.03) adverse reaction unresolved from previous treatments or not readily managed and controlled with supportive care. The presence of alopecia of any grade and peripheral neuropathy ≤ Grade 2 without pain is allowed.
- •Previous allogeneic stem cell transplantation with active graft versus host disease (GVHD), or treatment with immunosuppressive therapy in the 2 months prior to study entry.
- •No oral corticosteroids 3 days before initiating combinations Vactosertib/POM; inhaled corticosteroids are permitted.

研究组 & 干预措施
Vactosertib + Pomalidomide
Vactosertib tablets, taken once daily for the first and second dose levels and twice a day for third and fourth dose level levels for 5 days followed by 2 days without treatment, repeated for 28-day cycles until evidence of progressive disease, intolerable toxicity, or participant discontinuation.
For dose escalation - dosing initiated at 60 mg once daily by oral administration and will be increased to determine MTD. Provisional subsequent doses are 60, 120, once daily and 100 mg and 200 mg twice daily on days 1-5, 8-12, 15-19 and 22-26. Extension cohorts will enter at 200 mg twice daily (i.e. if MTD not defined) for 12 months until progression or intolerable toxicity.
POM is administered orally (4 mg/day daily on Days 1 - 21 days). Treatment will occur in a suitable outpatient ambulatory care setting that is equipped for monitoring of patients with hematopoietic malignancies undergoing early clinical trial research.
