Details and patient eligibility

About

The goal of this clinical trial is to determine the safety and efficacy of IP-001 for intratumoral injection administration following thermal ablation of a solid tumor.

Full description

The therapeutic approach taken by this clinical trial may offer patients a therapeutic benefit after failure of standard chemotherapy and immunotherapy.

Patients giving written informed consent will undergo screening during the Pretreatment Period to determine eligibility for trial entry. The Pretreatment Period will include collection and recording of medical history, concomitant medications, baseline symptoms, previous therapies, and baseline assessments. The patient's baseline tumor burden will be recorded with radiological assessments, along with analyzing location and size of tumors to identify and characterize target tumor(s) that will be treated and/or followed during the clinical trial.

If confirmed eligible for the study, the patient will advance into the Treatment Period. During the Treatment Period, patients will receive a routine radiofrequency ablation (RFA), followed by an injection of investigational product (IP-001 for Injection) into the tumor. Patients can be treated every 6 weeks for up to 4 treatments with RFA + IP-001 for Injection.

A patient will move to the 6-month Follow-up Period when the patient has completed 4 treatment cycles or if the decision is made that no subsequent treatments will be administered. During the Follow-up Period, there will be a Follow-up Visit every 6 weeks for 5 visits, at disease progression, or prior to the start of a new antineoplastic treatment.

2. Life expectancy of > 6 months. Only have lesions with the longest diameter of ≤ 5 cm.
3. Presence of at least one non-bone tumor lesion that is ablation-accessible, with a minimum size of 1.0 cm.
4. Measurable disease according to RECIST 1.1.
5. Age ≥ 18 years.
6. ECOG performance status 0-1.
7. Bone marrow function: neutrophil count ≥ 1.5 × 109/L, platelet count ≥ 100 × 109/L, hemoglobin ≥ 90 g/L.
8. Adequate hematological function defined by white blood cell count ≥ 2.5 × 109/L with absolute neutrophil count ≥ 1.5 × 109/L, and hemoglobin ≥ 9 g/dL (transfusions allowed on study).
9. Adequate hepatic function defined by a total bilirubin level ≤ 1.5 × the upper limit of normal (ULN) range and aspartate transaminase (AST) and alanine aminotransferase (ALT) levels ≤ 2.5 × ULN for all patients, or for patients with documented metastatic disease to the liver and AST and ALT levels ≤ 5 × ULN.

2. Malignant primary brain tumors or evidence of brain metastases or leptomeningeal disease.
3. Patients who have received chemotherapy, radiotherapy, immunotherapy, or concurrent or recent treatment with any other investigational agents within 21 days prior to treatment.
4. Patients who have not recovered to common terminology criteria for adverse events (CTCAE) Grade ≤ 1 from all side effects of prior therapies except for residual toxicities.
5. Patients with a history of malignancy, with the exception of non-melanoma skin cancers and in situ cancers.
6. Concomitant treatment with systemic corticosteroids (10 mg prednisolone or equivalent) or other immunosuppressive therapy.
7. Anti-coagulation therapies which cannot be stopped 24 hours prior to trial treatment.
8. Severe or uncontrolled cardiovascular disease (congestive heart failure New York Heart Association classification III or IV).
9. Documented HIV positive.
10. Active Hepatitis C or Hepatitis B Viral infection.
