Conditions
Summary
This is a Phase 1, multicenter, open-label dose escalation study to determine the safety and tolerability of intratumoral (IT) injection of tolododekin alfa (ANK-101) in participants with advanced solid tumors who have progressed during or after receiving standard of care (SOC) therapy or who will not benefit from such therapy. The study will be conducted in three parts; in Part 1, participants with superficial lesions will receive ANK-101 as a single agent; in Part 2, participants with visceral lesions will receive ANK-101 as a single agent; and in Part 3, participants with cutaneous squamous cell carcinoma (CSCC) will receive ANK-101 in combination with cemiplimab.
Eligibility
Inclusion Criteria14

- ECOG performance status 0-1
- life expectancy \> 12 weeks
- adequate bone marrow, hepatic and renal function
- baseline electrocardiogram (EKG) without evidence of acute ischemia or prolonged QTc interval \> 460 msec
- Human immunodeficiency virus (HIV) infected participants must be on anti-retroviral therapy (ART) and have well-controlled HIV infection/disease
- last dose of previous anticancer therapy (including investigational agents) ≥ 28 days, radiotherapy ≥ 14 days (targeted palliative radiotherapy is allowed for lesions not planned for injections), or surgical intervention ≥ 21 days prior to the start of treatment
- resolution of all prior anticancer therapy toxicities (except for alopecia or vitiligo) to ≤ Grade 1 (as per NCI CTCAE Version 5.0)
- willing to provide pre- and post-treatment tumor biopsy samples if medically feasible
- participant is capable of understanding and complying with protocol requirements
Exclusion Criteria18
- injectable tumors impinging upon major airways or blood vessels
- prior treatment with recombinant interleukin-12 (IL-12)
- have received systemic therapy with immunosuppressive agents ≤ 28 days before the start of treatment
- have received live vaccines within 28 days prior to the start of ANK-101 treatment
- have primary or acquired immunodeficient states (e.g., leukemia, lymphoma)
- a woman of childbearing potential (WOCBP) who has a positive serum pregnancy test (within 72 hours) prior to the start of treatment or female participant who is breastfeeding
- prior organ transplantation
- known history of hepatitis B virus, known active hepatitis C virus, or a positive serological test at screening within 28 days prior to the start of treatment
- HIV-infected participants with a history of Kaposi sarcoma and/or Multicentric Castleman Disease
- active autoimmune disease or medical conditions requiring chronic steroid (i.e., ≥ 20 mg/day prednisone or equivalent) or other immunosuppressive therapy within 28 days prior to the start of treatment
- known active central nervous system (CNS) metastases
- congestive heart failure (\> New York Heart Association Class II), active coronary artery disease, unevaluated new onset angina within 3 months or unstable angina (angina symptoms at rest), or clinically significant cardiac arrhythmias
- uncontrolled bleeding disorders within 4 weeks prior to the start of treatment or known bleeding diathesis - Note: Part 2 only: Participants with active bleeding diathesis or requirement for therapeutic anticoagulation that cannot be interrupted or altered for procedures
- history of hypersensitivity to compounds of similar biological composition to IL-12, aluminum hydroxide, or drugs formulated with polysorbate-20
- other systemic conditions or organ abnormalities that, in the opinion of the Investigator, may interfere with the conduct and/or interpretation of the current study
- any acute or chronic psychiatric problems or substance abuse disorder that, in the opinion of the Investigator, make the participant unsuitable for participation
- Part 3 only: prior Grade 3 or greater immune-mediated adverse events (imAEs) following treatment with an agent that blocks the programmed cell death protein 1 (PD-1)/programmed cell death ligand 1 (PD-L1) pathway.
- Part 3 only: hypersensitivity to cemiplimab or any of its excipients or contraindications to cemiplimab per approved local labeling
Interventions
IT administration of ANK-101 once every 3 weeks for up to 12 weeks (4 doses); if there is no disease progression, decrease in clinical performance status or unacceptable toxicity, participants may receive 4 additional doses of ANK-101.
Participants will receive four cycles of ANK-101 in combination with Cemiplimab. If there is no significant clinical deterioration as determined by the Investigator or unacceptable toxicity at Week 12, participants may receive an additional four cycles of the combination treatment. After stopping ANK-101 treatment, participants may stay on Cemiplimab monotherapy for an additional 24 weeks.
