Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions 4. Have at least 1 non-ulcerated, measurable, and accessible lesion for IT injection with a maximum diameter of 5 cm 5. Are able to provide tissue from a core or excisional biopsy at screening or have an acceptable stored tumor sample available that was collected within 90 days prior to screening 6. Have an ECOG performance status of 0 or 1 7. Have a life expectancy ≥3 months, as determined by the Investigator 8. Female patients of non-childbearing potential must be either surgically sterile (hysterectomy, bilateral tubal ligation, salpingectomy, and/or bilateral oophorectomy at least 26 weeks before screening), post-menopausal, defined as spontaneous amenorrhea for at least 2 years, or with follicle-stimulating hormone in the post-menopausal range at screening 9. Female patients of childbearing potential must have a negative serum pregnancy test at screening and agree to use a highly effective method for contraception from the time of signing the ICF until at least 120 days after the last administration of study treatment. Highly effective methods of contraception are birth control methods with a failure rate of <1% per year when used consistently and correctly, including the following: a. Combined estrogen- and progestin-containing hormonal contraception associated with inhibition of ovulation given orally, intravaginally, or transdermally; progestin-only hormonal contraception associated with inhibition of ovulation given orally, by injection, or by implant; intrauterine devices; and intrauterine hormone-releasing systems b.

Sterilization of male partner (at least 6 months prior to first study treatment dose) d. Complete sexual abstinence. Periodic abstinence and withdrawal are not acceptable. Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatment. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the study and the preferred and usual lifestyle of the patient. 10. Male patients able to father children, must agree to use 2 acceptable methods of contraception throughout the study. Sperm donation is not recommended from the time of signing the ICF until at least 120 days after the last administration of study treatment 11.
