Description of intervention(s) / exposure
Treatment: Drugs - Talimogene Laherparepvec
Treatment: Drugs - Pembrolizumab

Experimental: Phase Ib/II Talimogene Laherparepvec - Talimogene Laherparepvec

Experimental: Phase Ib/II Talimogene Laherparepvec + Pembrolizumab - Combination treatment of Talimogene Laherparepvec and Pembrolizumab


Treatment: Drugs: Talimogene Laherparepvec
Talimogene laherparepvec (T-VEC) administered by intralesional injection into liver tumors, with ultrasound/computed tomography (US/CT) guidance. Part 1: initial dose of T-VEC is 10\^6 plaque forming unit (PFU)/mL up to 4mL in Cohorts 1 \& 2, up to 8mL in Cohorts 3 \& 4 of the Group A \& Group B. The 1st cycle of T-VEC will be 21 (+3) days (from the 1st dose at 10\^6 PFU/mL to the 2nd dose at 10\^7 or 10\^8 PFU/mL). Subsequent cycles of T-VEC will be 21 (±3) days. Max. volume of T-VEC administered at any dose is 4mL (Cohorts 1, 2, 5, and 6) or 8mL (Cohorts 3 \& 4) for any individual lesion or for all lesions combined. Part 2: Initial dose of T-VEC is 10\^6 PFU/mL followed by subsequent T-VEC doses at a concentration of 10\^8 PFU/mL. T-VEC volume is up to 8mL based on the size of the inejected lesions. NOTE: as of Protocol Amendment 6 \[dated 26 October 2021\], intrahepatic injections of talimogene laherparepvec and liver biopsies are no longer performed in this study.

Treatment: Drugs: Pembrolizumab
Pembrolizumab is a non-Amgen Investigational product that is manufactured by Merck. Pembrolizumab will be labeled, packaged, and distributed by Amgen (or designee) using Amgen (or designee) clinical study drug distribution procedures. Pembrolizumab is supplied as pembrolizumab 100 mg/4 mL vials (25 mg/mL) solution for IV infusion. The trial treatment will consist of a total dose of 200mg administered intravenously every 3 weeks (day 1 of each cycle) for up to 35 cycles.

Key exclusion criteria
Subjects must not be candidates for surgery or locoregional therapy with curative intent or planned systemic anti-cancer therapy, with the exception of immunotherapy in the combination cohorts (Cohorts 5 and 6 in Part 1 and all subjects in Part 2). Liver tumors must not be estimated to invade approximately more than one-third of the liver. Liver tumor-directed therapy, hepatic surgery or major surgery, antibody-based therapy, or immunotherapy must not have been performed < 28 days, chemotherapy < 21 days, and targeted small molecule therapy or hormonal therapy < 14 days prior to enrollment. Subjects must either (1) have no central nervous system (CNS) metastasis, or carcinomatous meningitis, or (2) if CNS metastasis is present, must have stable treated cerebral metastases. Subjects must not have symptomatic auto-immune disease or be symptomatically immunosuppressed. They must not have a history of solid organ transplantation. For non-HCC, there must not be acute or chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. For HCC with prior hepatitis B and/or C infection, HBV and/or HCV viral load by qPCR must be undetectable, and they must not have had recent treatment within 12 weeks for HBV or HCV with certain antiviral medications in Part 1 Group B cohorts 1-5 and 6a, and Part 2 Group B HCC without viral hepatitis. For all patients in Part 1 and for patients in Part 2 where intrahepatic liver injection is planned (NOTE: as of Protocol Amendment 6 [dated 26 October 2021], intrahepatic injections of talimogene laherparepvec and liver biopsies are no longer performed in this study, enrollment for this study has stopped), there should be no macroscopic intravascular invasion of tumors into the main portal vein, hepatic vein, or vena cava.

Subjects in the combination treatment cohort must not have: a history or evidence of psychiatric, substance abuse, or any other clinically significant disorder; toxic effects of the most recent prior chemotherapy not resolved to grade 1 or less (except alopecia); or expected other cancer therapy while on study with the exception of local radiation to the site of bone or other metastasis for palliative treatment. Male subjects of reproductive potential in the combination treatment must be willing to use acceptable methods of effective contraception during treatment and through 4 months after the last dose of pembrolizumab.

Yes
What data in particular will be shared?
De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request

Supporting document/s available: Study protocol, Statistical analysis plan (SAP), Informed consent form (ICF), Clinical study report (CSR)
When will data be available (start and end dates)?
Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication (or other new use) have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities. There is no end date for eligibility to submit a data sharing request for this study.

In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling. Requests are reviewed by a committee of internal advisors, and if not approved, may be further arbitrated by a Data Sharing Independent Review Panel. Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement. This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
