Brief Summary

ASP1012 is a type of virus called an oncolytic virus which is used to treat some cancers. ASP1012 was changed in a laboratory to infect and kill cancer cells, leaving healthy cells alone. It also mak...

Eligibility Criteria

Inclusion

  • Participants in Parts 1 and 2 must have histologically, or cytologically, confirmed diagnosis of locally advanced or metastatic solid tumor(s).
  • Dose Escalation (Part 1) - all previously treated participants with solid tumor types
  • Dose Expansion (Part 2)
  • Participants with previously treated cutaneous melanoma, that is, anti-programmed cell death protein 1 (PD-1)/programmed death ligand 1 (PD-L1) alone or in combination with anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitor. Participants with BRAF-mutant melanoma must have received a v-raf murine sarcoma viral oncogene homolog B (BRAF) inhibitor as monotherapy or in combination with other targeted agents (for example, murine embryonic fibroblasts (MEK) inhibitors).
  • Participants with previously treated solid tumors,
  • Participants with stage IIIB to IIID or oligometastatic resectable stage IV, treatment-naïve melanoma that are amenable to resection.
  • Note: Participants with acral lentiginous melanoma will be excluded.
  • Participants in Part 3 (Dose Expansion) must have histologically, or cytologically confirmed diagnosis of either:
  • Previously treated (at least 1 line of prior therapy) gastric cancer (including gastroesophageal junction cancer \[type 2 and 3 only\]). Prior lines of therapy may include combination chemotherapy such as FOLFOX based regimen containing 5-flurouracil, leucovorin and oxaliplatin, targeted therapies against human epidermal growth factor receptor 2 (HER2+) tumors and checkpoint inhibitors.
  • Stage II to IV CRC in complete remission with no measurable disease as defined by RECIST v1.1 following surgical resection and adjuvant therapy with circulating tumor deoxyribonucleic acid (ctDNA) detectable by local testing; the ctDNA positivity will be confirmed during the trial by centralized testing Note: Participants with Stage IV CRC are limited to those with oligometastatic disease in liver. Participants with CRC must have received and completed standard of care and adjuvant therapies which may include fluoropyrimidine, oxaliplatin, bevacizumab, and irinotecan-based chemotherapy and surgery.

Participants with ovarian cancer must have received standard of care and adjuvant therapies which may include platinum-based chemotherapy and/or poly-ADP ribose polymerase (PARP) inhibitors.
  • Other solid tumor type (when identified), for example, a tumor type in which antitumor activity or biomarker response is observed in Parts 1 or 2 or additional tumor types of interest.
  • Participant has measurable disease as determined by RECIST v1.1, except for participants with CRC and ovarian cancer enrolled in Part 3. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
  • Participant has progressed, relapsed or discontinued for toxicity during or after the last systemic anti-neoplastic therapy and is unlikely to achieve clinical benefit from standard of care therapies per investigator, except for Part 2 participants with treatment-naïve melanoma and Part 3 (participants with CRC and ovarian cancer).

  • Participant must be willing and able to comply with the study requirements including prohibited concomitant medication restrictions.
  • Participant agrees not to participate in another interventional study while receiving ASP1012 in the present study/participating in the present study.

Exclusion
