Study of Talimogene Laherparepvec With Atezolizumab for Triple Negative Breast Cancer and Colorectal Cancer With Liver Metastases
A Phase 1b Study of Talimogene Laherparepvec in Combination With Atezolizumab in Subjects With Triple Negative Breast Cancer and Colorectal Cancer With Liver Metastases
Approximately 36 DLT-evaluable subjects will be enrolled in this study. The locations of the study will be in the United States, Australia, Europe and Switzerland.
The goal of this study is to evaluate the safety of intrahepatic injection (directly into the liver) of talimogene laherparepvec in combination with intravenously administered atezolizumab in subjects with triple negative breast cancer and colorectal cancer with liver metastases.

Detailed Description
The Screening period is 28 days prior to study enrollment. This study has 2 Cohorts. Cohort 1: Triple Negative Breast Cancer and Cohort 2: Colorectal Cancer. These cohorts will enroll in parallel. There will be a Safety Follow-up period and a Long Term Follow-up period.
Drug Administration: The participants will receive the study drugs in cycles. If the participants are found to be eligible to take part in this study, they will receive talimogene laherparepvec as an injection into the hepatic (liver) metastatic sites on Day 1 of each cycle along with receiving atezolizumab by intravenous infusion on Day 1 of each cycle. Each cycle is 21 days for 6 cycles. There is an option for an additional 6 cycles after the first 6 intra-hepatic cycles. After the first radiographic assessment at week 10, if all injectable liver lesions have been injected but the 4.0 mL maximum volume has not been used, injection of clinically assessed non-hepatic cutaneous, subcutaneous, and nodal tumor lesions with or without ultrasound guidance will be permitted. Liver lesions should be prioritized over cutaneous, subcutaneous and nodal lesions.
Treatment will continue until a participant experiences a DLT (Dose Limiting Toxicity) evaluated in the DLT period (which is 2 cycles from initial dose), has CR (Complete Response), has need for an alternative anticancer therapy or experiences a safety concern.
Study Visits: Cycle 1 to Cycle 12 - The participant will have a physical exam along with vital signs and ECOG (Eastern Cooperative Oncology Group) performance level assessment. Blood (about 2 Tablespoons) will be drawn for routine tests and to check the immune system. Adverse events and medications taken will be reviewed on each cycle.Biomarkers will be taken on cycles 1, 2, 3, 6, and safety FU. Tumor Markers (special lab tests associated with the cancer, such as particular proteins) will be completed will be take on cycles 1, 4, 7, 10, 13, every 3 cycles and SFU.
Central lab tests will be completed on cycles 1, 2, 3, and 6 and safety FU. Cycle 1 Archived (prior stored) tumor sample will be obtained. Also, a liver tumor biopsy will be completed at Cycles 1, 3 and 6.
Response Assessments will be completed at Screening and again at Cycles 4, 7, 10, 13 and every 3 cycles.
Throughout the trial a swab for Herpetic tumor will be obtained within 3 days of the event.
Cycle 1 to 12- The exposure to talimogene laherparepvec by the subject's healthcare provider and household member caregiver will be reviewed. Cycles 1, 3, 6-Liver tumor biopsy will be completed. Cycles 4, 7, 10, 13 and every 3 cycles -Response assessments will be completed by radiographic and clinical tumor assessment.
Length of Treatment:
A maximum for 12 cycles of talimogene laherparepvec are allowed during the study. The participant may continue taking the study drug for as long as the doctor thinks it is in their best interest. The participant will no longer be able to take the study drug if the disease gets worse, or if they are unable to follow study directions.
Safety Follow-up Visit:
Safety Follow-up visit will be performed about 30 days after the last dose of study treatment.
The participant will have a physical exam, have vital signs taken, assessment of ECOG status and have weight measured. Adverse events will be assessed as well as the concominant medications. Routine bloodwork and tumor markers will be taken.
Exposure to talimogene laherparepvec by the healthcare providers of the participant and/or close contacts will be assessed.
Long-Term Follow-up Visits: Participants will be followed for survival every 12 weeks from the date of the safety follow-up visit until approximately 24 months after the last subject is enrolled. Subsequent cancer treatments will be collected as part of the long-term follow-up survival assessment. This is an investigational study. The study doctor can explain how the study drugs are designed to work.
