CI Scientists Remarks:
About the molecule: ATG-010 (selinexor) is a oral selective inhibitor of nuclear export (SINE) compound discovered and developed by Karyopharm Therapeutics. It is currently being developed by Antengene, which has the exclusive development and commercial rights in certain Asia-Pacific markets, including Greater China, South Korea, Australia, New Zealand and the ASEAN countries
Selinexor is approved as XPOVIO in the US for MM & DLBCL and has conditional approval in Europe for RRMM
Results from Phase 3 BOSTON study: Selinexor + bortezomib + dexamethasone (N=195) vs bortezomib + dexamethasone (N=207) in patients with RRMM:
ORR: 76.4%
PFS: 47%
Peripheral neuropathy of grade 2 or above: 21% vs 34%
Grade 3–4 adverse events: Thrombocytopenia 39% vs 17%, fatigue 13% vs 1%, anaemia 16% vs 10%, and pneumonia 11% vs 11%
US FDA approved Selinexor for 3 indications within 18 months, expecting the similar trend, Antengene has submitted multiple NDAs in different countries and is also conducting Phase 3 SIENDO trial in patients with endometrial cancer
