STC-15 as a Part of Combination Therapy With Toripalimab in Selected Advanced Cancers
Sponsor: STORM Therapeutics LTD
ClinicalTrials ID:NCT06975293
This trial evaluates the safety, tolerability, and antitumor activity of STC-15 with toripalimab in advanced cancers. It includes a dose escalation phase and an antitumor activity assessment. Eligible adults must have measurable disease, prior therapy progression, and the ability to take oral medication. The intervention involves 21-day cycles of the combination therapy.

Program Overview
This early phase oncology trial will be conducted at various study centers to investigate the safety, tolerability, and antitumor activity of STC-15 (a METTL3 inhibitor) in combination with toripalimab (anti- programmed cell death 1 [PD-1]) in four different locally advanced unresectable or metastatic tumors such as indications: (1) in combination with toripalimab (anti- programmed cell death 1 [PD-1]) in locally advanced and unresectable or metastatic non-small cell lung cancer (NSCLC), (2) in combination with toripalimab in locally advanced unresectable or metastatic melanoma, (3) in combination with toripalimab in locally advanced unresectable or metastatic endometrial cancers, and (4) in combination with toripalimab in locally advanced or metastatic head and neck squamous cell carcinoma (HNSCC).
This study comprises of 2 parts: a combination dose escalation part (Phase 1b) followed by an assessment of the combination treatment's antitumor activity (Phase 2). This study will be conducted in adult participants with advanced malignancies to characterize the safety, tolerability, PK, and clinical activity of STC-15 in combination with toripalimab.

- Have the ability to swallow, retain, and absorb oral medication.
Inclusion Criteria (Expansion):
- NSCLC (when applicable): Participants with AGAs (actionable genetic alterations) must have received targeted therapy unless contraindicated. Participants must not have received more than three previous lines of systemic treatment for unresectable locally advanced or metastatic disease. This must include at least a prior anti-PD-1/L1 alone or in combination with chemotherapy. Participants must have disease progression on prior anti-PD-1/L1.
- HNSCC (when applicable): Participants must have progressed on following prior lines: 2L or 3L recurrent/metastatic disease; regardless of PD-L1 score. Participants must not have received more than three previous lines of systemic treatment for unresectable locally advanced or metastatic disease. This must include at least a prior anti-PD-1/L1 alone or in combination with chemotherapy.
- Endometrial (when applicable): Participants must not have received more than three previous lines of systemic treatment for unresectable locally advanced or metastatic disease. This must include at least a prior anti-PD-1/L1 alone or in combination with chemotherapy. Participants must have disease progression on prior anti-PD-1/L1
- Melanoma (when applicable): Participants must not have received more than three previous lines of systemic treatment for unresectable locally advanced or metastatic disease. This must include at least a prior anti-PD-1/L1 alone or in combination with chemotherapy. Participants must have disease progression on prior anti-PD-1/L1.
Key
