      This is a phase 1 open-label, single center, dose escalation study to determine a safe and
      effective maximum tolerated dose of HS-130 in combination with viagenpumatucel-L (HS-110) for
      adult subjects with advanced solid tumors who are refractory to Standard of Care.
    

Eligibility criteria:

        Inclusion Criteria:

          1. Patients with metastatic or advanced, unresectable solid tumor who have progressed, or
             recurred following standard-of-care (SOC) therapies or are ineligible for safe and
             effective SOC therapies and for whom, in the opinion of the Investigator, experimental
             therapy with HS-130/HS-110 may be beneficial.

          2. Patients should have lesions that are safely accessible for biopsy and be willing to
             provide pre-treatment and on-treatment tissue biopsy. Fine-needle aspiration biopsy is
             not acceptable. Archival tumor tissue will be accepted in lieu of fresh biopsy at
             screening if sample was collected within 6-months from Cycle 1 Day 1, and the local
             pathologist confirms that an adequate amount of tissue/tumor cells exist to allow
             completion of all testing as outlined in the specimen collection manual.

          3. Age ≥ 18 years.

          4. Have an acceptable organ function:

          6. Life expectancy of at least three months.

          7. Patients, both females and males, of childbearing/reproductive potential must agree to

             last treatment with HS-130 and/or HS-110.

          8. Patients must be willing and have the capacity to sign the informed consent form.
