STC-15 as a Part of Combination Therapy With Toripalimab in Selected Advanced Cancers
What this study is about
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)

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Estimated life expectancy ≥ 3 months.
- ECOG performance status 0 or 1.
- Measurable disease according to RECIST v1.1 as assessed by the local site investigator/radiology.
- Documented radiologic assessment of progression on the prior therapy before study entry.
- Have adequate organ function.
- Have the ability to swallow, retain, and absorb oral medication. Inclusion Criteria (Phase 2 Monotherapy Cohorts):
- Have histologic or cytologic confirmation of advanced sarcoma of the selected histologic subtype that is not amenable to local curative therapy. Participant must have received at least 2, but no more than 4 prior lines of systemic therapy.
- Pre-treatment and on-treatment biopsy if medically feasible. Key
Exclusion criteria
- Pregnant and lactating women.
- Received prior systemic anticancer therapy including investigational agents within 4 weeks or 5 half-lives, whichever is shorter, prior to first IMP administration.
- Participants who have not recovered from all AEs due to previous therapies to Grade ≤ 1 or baseline, according to NCI-CTCAE v5.0. Exceptions include: alopecia, Grade ≤ 2 neuropathy, and endocrine-related AEs Grade ≤ 2 who are stable on treatment or hormone replacement.
- History of (non-infectious) pneumonitis/interstitial lung disease that required steroids or the presence of ongoing pneumonitis/interstitial lung disease).
- Clinically significant cardiovascular disease or condition.
- Known active CNS metastases and/or leptomeningeal disease.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
