Exceptions include non-metastatic basal cell or squamous cell carcinomas of the skin, prostate cancer or cancer in situ that does not require treatment currently or is otherwise under control
* Requiring chronic systemic immunosuppressants, including steroids \> 20 mg/day
* Presence of bulky disease defined as any single mass \> 5 cm in greatest dimension will trigger a discussion to determine eligibility
* New York Heart Association (NYHA) Class \>3 of left ventricular ejection fraction (LVEF) \< 50%
* Prolonged corrected QT interval as determined by 12-lead electrocardiogram
* Has spinal cord compression or clinically unstable brain metastases within 4 weeks of first dose of study drug
* Evidence of active herpes infection and/or chronic herpes infection requiring prophylactic antiviral medication that may not be discontinued
* Has an active or recent COVID-19 infection, must have a negative RT-PCR test and not have had symptoms within 4 weeks of day 1 of study drug administration
* Any active infection requiring systemic therapy within 72 hours of injection of STI-1386, excluding anti-viral maintenance therapy for HIV
* Moderate to severe chronic obstructive pulmonary disease or other moderate to severe chronic respiratory conditions unless under treatment and stable for the 3 months of screening
