Safety Extension Study for Subjects With HR+, HER2- Breast Cancer for Subjects Who Have Completed the OVELIA Study
Safety Extension Study for Subjects With HR+, HER2- Breast Cancer for Subjects Who Have Completed the OVELIA Study

NCT05645536

Enrolling By InvitationPhase 3

Sponsor: Tolmar Inc.

Conditions: Breast Cancer

Interventions: TOL2506, Tamoxifen, Letrozole tablets, Anastrozole Tablets, Exemestane Tablets

Countries: United States, Argentina, Brazil, India, Mexico, Puerto Rico

TOL2506A (OVELIA) is a Phase 3, single arm, open-label study evaluating the effectiveness of TOL2506 in suppressing ovarian function in premenopausal women with HR+, HER2-negative breast cancer and men with HR+ breast cancer. The TOL2506A-EXT study described here is a safety extension study to assess and collect long-term data on the ongoing safety and tolerability of TOL2506 in combination with tamoxifen or an AI for up to 4 years.
