研究概览
简要总结
This phase I trial studies the best dose and side effects of talimogene laherparepvec in combination with 5-fluorouracil, leucovorin, oxaliplatin, capecitabine, and chemoradiation before surgery in treating patients with rectal cancer that has spread from where it started to nearby tissue and lymph nodes. Drugs used in immunotherapy, such as talimogene laherparepvec, may stimulate the body's immune system to fight tumor cells. Drugs used in chemotherapy, such as 5-fluorouracil, leucovorin, oxaliplatin, and capecitabine work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Giving talimogene laherparepvec, 5-fluorouracil, leucovorin, oxaliplatin, and capecitabine and chemoradiation before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

入选标准
- •For dose escalation: Patients must have A) histologically or cytologically confirmed low lying (up to 6 cm of anal verge) rectal adenocarcinoma eligible for radiation therapy to rectal tumor, B) if the treatment is palliative in the metastatic setting, no additional requirements for tumor size or nodal involvement is needed; C) if the treatment is in the neoadjuvant setting, the tumor must ALSO be high-risk locally advanced rectal cancer defined as T3-4, N+, and/or at risk for a positive radial margin (as determined by the surgeon)
- •For dose expansion: Patients must have A) histologically or cytologically confirmed rectal adenocarcinoma eligible for radiation therapy to rectal tumor irrespective of location from anal verge, B) if the treatment is palliative in the metastatic setting, no additional requirements for tumor size or nodal involvement is needed; C) if the treatment is in the neoadjuvant setting, the tumor must ALSO be high-risk locally advanced rectal cancer defined as T3-4, N+, and/or at risk for a positive radial margin (as determined by the surgeon)
