The purpose of this study is to determine if an oncolytic virus called Talimogene laherparepvec (a modified herpes simplex 1 virus that can specifically destroy cancer cells while leaving normal cells alone) injected directly into the tumor during chemotherapy prior to surgery can enhance the elimination of triple negative breast cancer tumors. The natural herpes simplex 1 virus typically causes cold sores around the mouth, but the talimogene laherparepvec version of the herpes virus has been changed to prevent it from reproducing in normal tissue.
However, it can still attack and break open cancer tissue which is why it is used as a treatment for cancer. It is thought that this virus can also help recruit the participant's immune system to attack the cancer cells during their treatment and possibly destroy the tumor tissue more effectively than chemotherapy alone. This virus is already FDA approved to treat melanoma skin tumors, so investigators want to determine if this virus can achieve a similar benefit in women with triple negative breast tumors.

Experimental: Talimogene laherparepvec + Chemotherapy
Talimogene laherparepvec with Neoadjuvant Paclitaxel Chemotherapy treatment administration on an outpatient basis. Phase I: Dose Escalation to Determine Maximum Tolerated Dose (MTD). Phase II: Treatment at MTD.
Biological: Talimogene laherparepvec
Talimogene laherparepvec injection. Phase I: Dose escalation. Phase II: Treatment at Maximum Tolerated Dose (MTD) from Phase I. The MTD dose level is defined as the highest dose level with ≤1 out of 6 patients experiencing a dose limiting toxicity (DLT).
Paclitaxel chemotherapy infusion. The paclitaxel weekly dose is fixed at 80 mg/m^2.
