ViCToRy: Vorasidenib in Combination With Tumor Specific Peptide Vaccine for Recurrent IDH1 Mutant Lower Grade Gliomas
Katy Peters, MD, PhD
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.
Description
This study is designed to assess the safety and efficacy of the PEPIDH1M vaccine in combination with vorasidenib in adult patients recurrent IDH1 mutant lower grade gliomas. Patients will receive vaccination with 0.5 mL of Td (tetanus and diphtheria toxoids adsorbed) intramuscularly (I.M.) into the deltoid muscle to ensure adequate immunity to the tetanus antigen. Patients will then receive vorasidenib 40 mg 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 a…

Interventions
- DrugPEPIDH1M 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.
