Study of the Safety, Tolerability and Efficacy of KPT-8602 in Patients With Relapsed / Refractory Cancer Indications

Trial Status: Closed to Accrual

This is a first-in-human, multi-center, open-label clinical study with separate dose escalation (Phase 1) and expansion (Phase 2) stages to assess preliminary safety, tolerability, and efficacy of the second generation oral XPO1 inhibitor KPT-8602 in patients with relapsed / refractory multiple myeloma (MM), metastatic colorectal cancer (mCRC), metastatic castration resistant prostate cancer (mCRPC), and higher risk myelodysplastic syndrome (HR-MDS). Dose escalation and dose expansion may be included for all parts of the study as determined by ongoing study results.

Inclusion Criteria

  • INCLUSION CRITERIA 1. Written informed consent obtained prior to any screening procedures and in accordance with federal, local, and institutional guidelines. 2. Age ≥ 18 years. Higher Risk Myelodysplastic Syndrome (Part F): 3. Documented diagnosis of MDS with 5-19% myeloblasts. 4. Patients should be intermediate-2 or high-risk MDS by International Prognostic Scoring System (IPSS). 5. Patients believed to be IPSS high risk, without clearly meeting IPSS categories above should be discussed with the medical monitor prior to enrolling. 6. HMA refractory patients including: 1. ≥ 2 cycles of azacitidine and/or decitabine or experimental agents (such as SGI-110 or ASTX727 or similar) with clear progressive disease (PD) (no count recovery with ≥50% increase in bone marrow blasts) OR 2. ≥ 4 cycles of azacitidine and/or decitabine (or other hypomethylating therapy) with lack of improvement (no CR/CRi/PR/HI). 7. Patients receiving a stable dose of erythropoiesis-stimulating agent (ESA) for at least 1 month at the time of study entry may continue to receive ESA. EXCLUSION CRITERIA Patients in All Parts of the Study: 1. Major surgery within 4 weeks before C1D1. 2. Impaired cardiac function or clinically significant cardiac diseases. 3. Uncontrolled active severe systemic infection requiring parenteral antibiotics, antivirals, or antifungals within one week prior to C1D1. 4. Patients with known symptomatic brain metastasis. 5. Prior malignancies: 1. Patients in All Parts of the Study: Patients with adequately resected basal or squamous cell carcinoma of the skin, or adequately resected carcinoma in situ (i.e. cervix) may enroll irrespective of the time of diagnosis. 2. Patients with Higher Risk MDS only: Concomitant malignancies or previous malignancies with less than a 1-year disease free interval at the time of enrollment. INDICATION-SPECIFIC EXCLUSION CRITERIA Higher risk Myelodysplastic Syndrome (Part F): 6. IPSS low or intermediate-1 risk MDS. 7. Evidence of transformation to AML by World Health Organization (WHO) (≥20% blasts in bone marrow or peripheral blood). 8. Patients receiving granulocyte-colony stimulating factor (G-CSF) or granulocyte macrophage-colony stimulating factor (GM-CSF) within the 3 weeks prior to C1D1.
