Participant must have a pathology report indicating the diagnosis of their STS.
  • Participant must have received at least 1 line of therapy for a STS and must have progressed following anthracycline-based or alternative standard therapies, except if medically contraindicated or refused by participant.

  • Neutrophils ≥ 1500/μL (≥ 1.5× 109/L).
  • Prothrombin Time (PT), and International Normalized Ratio (INR) ≤ 1.5× Upper Limit of Normal (ULN), platelets ≥ 100,000/μL (≥ 10× 109/L); hemoglobin ≥ 9 g/dL. Criteria must be met without erythropoietin dependency and without packed red blood cell transfusion within the last 2 weeks.
  • Creatinine within normal range; or calculated creatinine clearance > 50 mL/min by the Cockcroft-Gault equation.

Women of non-childbearing potential are defined as women with functioning ovaries with a documented history of tubal ligation or hysterectomy or females who are post menopausal, as defined by 12 months of spontaneous amenorrhea with an appropriate clinical profile, e.g., age appropriate, > 45 years, in the absence of hormone replacement therapy. In questionable cases, a blood sample for Follicle Stimulating Hormone (FSH) and estradiol will be obtained to confirm childbearing potential.

Experimental

INT230-6 administered intratumorally. Participants will be dosed every 2 weeks (± 2 days) for up to a total of 5 treatment sessions (e.g., Days 1, 15, 29, 43 and 57). Once the participant has completed the treatment phase, they will continue into a 22-month maintenance phase, where investigators may inject new lesions or previously injected lesions with up to 175 mL of INT230-6 every 12 weeks (Q12W) ± 14 days. Dose volume in a session is dependent on the participants presenting tumor burden.
