What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 126 participants in total. It began in 2024-07-24 with a primary completion date of 2029-12.

Brief Summary

The purpose of this study is to evaluate the safety and efficacy of a single injection of IP-001 as adjuvant therapy after local ablation or surgical resection and ablation in patients with hepatocellular carcinoma (HCC).

Eligibility Criteria

Inclusion Criteria: * Age ≥ 18 years at time of signing Informed Consent. * Has a diagnosis of hepatocellular carcinoma (HCC) documented radiologically by American Association for the Study of Liver Diseases (AASLD) criteria and/or histopathologically from a tumor biopsy. * Has a treatment plan to receive either a curative ablation (RFA or MWA) or a curative surgical resection and ablation. * Has HCC with intermediate, high or very high risk of recurrence. * Has hepatic only HCC (disease confined to the liver only), defined by no extra-hepatic lesions greater than 1 cm in size. * Has an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. * Patient with past or ongoing hepatitis C virus (HCV) infection will be eligible if the patient has completed HCV treatment at least 1 month prior to Day 1. * Patient with controlled hepatitis B will be eligible if the patients meets the following criteria: 1. Antiviral therapy for hepatitis B virus (HBV) must be given for at least 4 weeks and HBV viral load must be less than 500 IU/mL prior to treatment. Patients on active HBV therapy with viral loads under 00 IU/mL should stay on the same therapy throughout study treatment. 2. Patients who are hepatitis B core antibody (anti-HBc) positive, negative for HBsAg, and negative or positive for anti- HBs, and who have an HBV viral load under 500 IU/mL do not require HBV anti-viral prophylaxis. * Has adequate organ function as specified in the Adequate Organ Function Laboratory Values Table. Specimens must be collected within 14 days prior to Day 1. Exclusion Criteria: * Known allergic reaction to shellfish, crabs, crustacean, or any trial components. * Has an active infection requiring systemic therapy. * Has a diagnosis of immunodeficiency or currently receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent), or any other form of immunosuppressive therapy within 7 days prior to treatment day (Day 1), or has plans to start treatment including \>10 mg daily of prednisone equivalent or any immunotherapy. * Has an active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents or immunosuppressive drugs). NOTE: replacement therapy (e.g., thyroxine or insulin) is not considered a form of systemic treatment and is allowed. * Has had an allogenic tissue/solid organ transplant. * History of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug-induced pneumonitis, active tuberculosis, or idiopathic pneumonitis. * Has received local therapy to liver, ablation other than radiofrequency or microwave ablation (i.e., alcohol ablation, transcatheter chemoembolization, transcatheter embolization, hepatic arterial infusion, local radiation/Stereotactic Body Radiation Therapy or radioembolization) less than 3 months prior to treatment. * Is receiving any of the following prohibited concomitant therapies less than 21 days from treatment or 5 drug elimination half-lives, whichever is shorter prior to randomization: 1. Antineoplastic systemic chemotherapy or biological therapy. 2. Immunotherapy not specified in this protocol. 3. Systemic glucocorticoids for any purpose other than to modulate symptoms from an adverse event (AE) that is suspected to have an immunologic etiology. Inhaled or topical steroids are allowed, and systemic steroids at doses ≤10 mg/day prednisone or equivalent are allowed. Exception: steroids may be used for premedication prior to imaging. * Has received a live vaccine within 28 days prior to treatment Day 1.
