Trial to Evaluate the Safety ofTalimogene Laherparepvec Injected Into Liver Tumors Alone and in Combination With Systemic Pembrolizumab

NCT02509507

Description:

This is a phase 1b/2, multicenter, open-label trial to evaluate the safety of talimogene laherparepvec injected intrahepatically into liver tumors with known progression alone and in combination with systemic IV administration of pembrolizumab, in subjects with non-HCC liver metastases from BC, CRC, GEC, melanoma, NSCLC, RCC, and subjects with HCC. The study consists of 2 parts and 2 groups, and Part 2 includes 2 stages. The objective of Part 1 is to evaluate the safety of intrahepatic injection of talimogene laherparepvec into liver tumors alone and in combination with systemically administered pembrolizumab for the non-HCC (Group A) and HCC (Group B) cohorts separately. Part 2 consists of 2-stage design to evaluate the efficacy and safety of talimogene laherparepvec in combination with systemic pembrolizumab. Efficacy and safety will be evaluated in each of the six non-HCC tumor types from Group A separately. Similarly, the efficacy and safety of the combination treatment will be determined for Group B HCC subjects.

Purpose

This is a phase 1, multicenter, open-label trial to evaluate the safety of talimogene laherparepvec, injected intrahepatically, into liver tumors with known progression in subjects with Hepatocellular carcinoma and subjects with liver metastases from breast adenocarcinoma, colorectal adenocarcinoma, gastroesophageal cancer (adenocarcinoma or squamous cell carcinoma), melanoma, non-small cell lung cancer, or clear cell renal cell carcinoma. The study consists of 2 parts and 2 groups. Part 1 is a 3+3 dose escalation consisting of 3 sequential dose cohorts each administering talimogene laherparepvec in increasing dose concentrations and dose volumes. In Part 1, the Maximum Tolerated Dose determination of non-hepatocellular carcinoma liver metastases (Group A) will be evaluated separately from hepatocellular carcinoma (Group B), and each dose cohort will need to be deemed safe for non-hepatocellular carcinoma subjects before it will be administered in hepatocellular carcinoma subjects. Part 2 consists of expansion cohorts administering the Maximum Tolerated Dose of talimogene laherparepvec determined from Part 1 for Groups A (non-hepatocellular carcinoma) and B (hepatocellular carcinoma) to approximately 10 subjects for each tumor type.

Eligibility Criteria

        Inclusion Criteria:

          -  Subjects must have histologically confirmed breast adenocarcinoma, colorectal
             adenocarcinoma, gastroesophageal cancer (adenocarcinoma or squamous cell carcinoma),
             melanoma, non-small cell lung cancer, or clear cell renal cell carcinoma with liver
             metastases or hepatocellular carcinoma with known disease progression.

          -  Non-hepatocellular carcinoma subjects must have received at least 1 prior standard of
             care systemic anti-cancer therapy for their metastatic disease.

          -  Subjects must have measurable liver tumors that are suitable for injection.

          -  Eastern Cooperative Oncology Group performance status must be 0 or 1, and life
             expectancy should be approximately 5 months or more.

          -  Adequate hematological, renal, hepatic and coagulation function is required.

          -  Child-Pugh score must be A to B7.

        Exclusion Criteria:

          -  Subjects must not be candidates for hepatic surgery or locoregional therapy of liver
             tumors with curative intent or planned systemic anti-cancer therapy.

          -  Liver tumors must not be estimated to invade approximately more than one-third of the
             liver.

          -  Liver tumor-directed therapy, hepatic surgery, antibody-based therapy, or
             immunotherapy must not have been performed < 28 days, chemotherapy < 21 days, and
