- Registration Number
- NCT02649790
- Lead Sponsor
- Karyopharm Therapeutics Inc
- Brief Summary
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 participants with relapsed/refractory multiple myeloma (MM), metastatic colorectal cancer (mCRC), metastatic castration resistant prostate cancer (mCRPC), higher risk myelodysplastic syndrome (HRMDS), acute myeloid leukemia (AML) and newly diagnosed intermediate/high-risk MDS.
Dose escalation and dose expansion may be included for all parts of the study as determined by ongoing study results.

Group Intervention Description Part C: CRC- KPT-8602 single agent KPT-8602 Participants were treated with KPT-8602 at a dose and schedule that has been cleared in Part A (completed). Part B: RRMM- KPT-8602 with low-dose dexamethasone; QDx5/week KPT-8602 Participants received KPT-8602 for 5 consecutive days (QDx5/week) in combination with low dose dexamethasone (20 milligram \[mg\] on Days 1, 3, 8, 10, 15, 17, 22, and 24 of each 28-day cycle) (completed). Part D: mCRPC- KPT-8602 single agent KPT-8602 Participants were treated with KPT-8602 at a dose and schedule that has been cleared in Part A (completed). Part E: mCRPC- KPT-8602 with abiraterone and corticosteroids KPT-8602 Participants were treated with KPT-8602 at a dose and schedule that had been cleared in Part A in combination with abiraterone and corticosteroids. Participants continued to receive the dose and schedule of abiraterone and corticosteroids that they were receiving at the time of enrollment (completed). Part G: Newly Diagnosed Intermediate/High-Risk MDS -KPT-8602 with ASTX727 ASTX727 Participants will receive KPT-8602 once daily at escalated doses. The starting dose for KPT-8602 is 5 mg orally once daily from Day 8 to Day 28 (Weeks 2 to 4) on a 28-day cycle in combination with ASTX727. Part H: AML Maintenance Therapy- KPT-8602 single agent KPT-8602 Participants with high-risk acute myeloid leukemia (AML) prior to transplant will be enrolled to receive maintenance therapy with KPT-8602 post-allogeneic stem cell transplantation. The dose for KPT-8602 will be 10 mg (RP2D from Part F) oral, to be administered once daily from Day 1 to Day 21 (Weeks 1 to 3) on a 28-day cycle. Part A1: RRMM- KPT-8602 single agent; QoDx5/week KPT-8602 Participants received KPT-8602 once daily for 5 days per week (QDx5/week) at escalated doses (completed). Part A2: RRMM- KPT-8602 single agent; QoDx3/week KPT-8602 Participants received KPT-8602 once daily for 3 days per week (QoDx3/week). The starting dose for Part A2 will be informed by Part A1 (completed). Part F: High-risk Myelodysplastic Syndrome (MDS)- KPT-8602 single agent KPT-8602 Participants were treated with KPT-8602 at a dose and schedule that had been cleared in Part A. In select cases (for example, participants achieving stable disease \[SD\], hematological improvement \[HI\], partial response \[PR\] and tolerating treatment, etc.), the dose may be escalated 1 level based on safety and efficacy considerations (completed). Part F Phase 2: RR High-risk MDS- KPT-8602 single agent KPT-8602 Participants will be enrolled at recommended Phase 2 doses (RP2D) of 10 mg daily on Days 1 to 5 of each week, in a dose expansion, based upon the results from the Phase 1 portion of Part F. Part G: Newly Diagnosed Intermediate/High-Risk MDS -KPT-8602 with ASTX727 KPT-8602 Participants will receive KPT-8602 once daily at escalated doses. The starting dose for KPT-8602 is 5 mg orally once daily from Day 8 to Day 28 (Weeks 2 to 4) on a 28-day cycle in combination with ASTX727. Part B: RRMM- KPT-8602 with low-dose dexamethasone; QDx5/week Dexamethasone Participants received KPT-8602 for 5 consecutive days (QDx5/week) in combination with low dose dexamethasone (20 milligram \[mg\] on Days 1, 3, 8, 10, 15, 17, 22, and 24 of each 28-day cycle) (completed).
