Phase 1/2 Clinical Trial Data for IDE196 Presented at Society for Melanoma Research Congress
Data was presented by Dr.
"We are evaluating IDE196 at two dose regimens of 300 mg BID and 400 mg BID following a 200mg BID run-in for the first seven days of dosing. Our hypothesis is that the run-in approach, which was has not been previously tested in a monotherapy setting, may improve tolerability and potentially increase exposure," said Dr.
"There is need for more effective therapies for patients facing Metastatic Uveal Melanoma. We are pleased to see the preliminary safety and tolerability of IDE196 in Phase 1 of the clinical trial, which may enable a duration of treatment that may be impactful," said Dr.
Key highlights as of
- Dosing schema: Cohort 1 patients (n=6) received 300mg BID, and Cohort 2 patients (n=6) received 200mg BID for the first 7-days (run-in) and then 400mg BID for all subsequent doses
- Run-in dosing schema utilized in Cohort 2 with objective to enhance exposure and improve tolerability
- 27 total patients enrolled in the Phase 1 dose escalation portion including:
- 12 patients in the two MUM DLT cohorts (6 patients at 300mg BID, and 6 patients using run-in to 400 mg BID)
- 14 patients in a MUM overflow cohort (6 patients at 300mg BID, and 8 patients using run-in to 400 mg BID)
- 1 cutaneous melanoma patient having a tumor with a GNA11 mutation (GNA11 patient) in a non-MUM GNAQ/11 cohort
- All 12 patients in the two DLT cohorts remained on therapy with Duration of Treatment ranging from 1.3 to 4.0 months, as of the
- No dose limiting toxicities were reported in the two MUM DLT cohorts; no adverse events > Grade 3 and no patient discontinuations due to AEs were reported in any patients
- Additional Phase 1 patients enrolled in this ongoing trial post-
- On-track for Phase 2 dose-selection and expansion into the potential registration-enabling portion of the trial for MUM in
- Interim data with efficacy for GNAQ/11 Phase 1/2 basket trial expected in Q2/Q3 2020
"We have achieved several key milestones for IDE196 monotherapy, including completing enrollment ahead of schedule in the Phase 1 dose escalation portion of our Phase 1/2 clinical trial, the first confirmed Complete Response in a MUM patient at month 31, and receiving
"We are excited for the opportunity to advance the targeted agent IDE196 to its next stage of development for patients with MUM and other solid tumors with GNAQ/GNA11 mutations. There is a high unmet medical need in MUM, where there are no
