Status: Recruiting
Location: See location...
Intervention Type: Drug
Study Type: Interventional
Study Phase: Phase 1
SUMMARY

The purpose of this study is to determine the safety and efficacy of a PEPIDH1M vaccine in combination with vorasidenib, a dual inhibitor of mutant IDH1 and IDH2 enzymes, in adult patients diagnosed with recurrent IDH1 mutant lower grade gliomas.

Participants
Target number of participants: 48
Treatments
Experimental: PEPIDH1M vaccine + vorasidenib
Patients will receive vaccination with 0.5 mL of Td (tetanus and diphtheria toxoids) intramuscularly into the deltoid muscle. Patients will then receive vorasidenib 40mg orally once a day for 28 days. After two cycles of 28-day vorasidenib and at the start of the 3rd cycle of vorasidenib, patients will receive the PEPIDH1M vaccine intradermally (i.d.) to alternating groin regions on the following schedule: vaccine #1, day 1; vaccine #2, day 15. The day before vaccine #1, patients will receive a vaccine site pre-conditioning injection of a single dose of Td toxoid. This will be administered twelve hours to one day prior to receiving PEPIDH1M vaccine i.d. to the RIGHT groin area. Vaccines #3 and #4 will be given on day 1 and day 15 of cycle 4. Starting on 6th cycle of 28-day vorasidenib, subjects will receive PEPIDH1M vaccine (i.d. to alternating groin regions) every 28 days on day 1 for vaccine #5-#12. Patients will receive up to a total of 14 cycles of vorasidenib.
