Brief summary
In this Phase 2 study, we will conduct an efficacy and safety study of the combination of investigational drug BMX-001, with short-course radiotherapy (SCRT) or long-course chemoradiotherapy (LCCRT) as part of total neoadjuvant therapy in newly diagnosed rectal adenocarcinoma (RAC) patients.
Detailed description
In this trial, we will enroll patients in two cohorts: Cohort 1: A 6 patient safety lead-in for patients receiving capecitabine prior to beginning a randomized trial for the Long Course Chemo-radiation (LCCRT) cohort. There will be trial stopping rules to review safety and PK data prior to initiating the randomized trial of patients receiving LCCRT. Cohort 2: The Randomized Short Course Radiation (SCRT) cohort. Cohort 1 and 2 will begin enrolling concurrently. Cohort 1 will have a safety lead-in of patients receiving LCCRT (with capecitabine). Cohort 2 will begin with the randomized study of patients receiving SCRT, while the LCCRT cohort is going through the safety lead-in portion. There are stopping rules for the LCCRT cohort 1 pending PK analysis as well as an AE review from the treatment period plus 1 week post BMX-001 treatment for the 6 patients prior to moving on with the randomized portion of the study for the LCCRT cohort. All patients in the safety lead-in portion of the trial will receive BMX-001 (A loading dose of 28 mg/subject followed by maintenance doses of 14 mg/subject twice a week) with either SCRT or LCCRT. Patients will receive 3 cycles of FOLFOX or 2 cycles of CAPOX and then be assigned to SCRT or LCCRT prior to randomization. Patients will be randomized (stratified by gender) to BMX-001 or no BMX-001. The randomized trial in each cohort will involve SCRT or LCCRT with or without BMX-001. After conclusion of radiation, patients will then receive 6 more cycles of FOLFOX or 4 more cycles of CAPOX. Skin, GI, and GU symptoms will be measured on the day of screening, before and after RT.

Inclusion criteria
1. Patients with pathologically confirmed locally advanced rectal adenocarcinoma who will be receiving total neoadjuvant therapy regimen with curative intent. 2. AJCC stage II to III rectal adenocarcinoma that will require total neoadjuvant therapy. 3. Adult, age \> or equal to 18 years (for Nebraska, age of consent is ≥19 years old) 4. ECOG Performance Status 0-2 5. Hemoglobin ≥ 9.0 g/dl, ANC ≥ 1,500 /dl, platelets ≥ 100,000 /dl (The use of transfusion or other intervention to achieve Hgb \> 9.0 g/dl is acceptable) 6. Serum SGOT and bilirubin ≤ 1.5 times upper limit of normal 7. Adequate renal function defined as follows: 1)Serum creatinine \< 1.5 mg/dl within 2 weeks prior to enrollment or 2)Creatinine clearance (CC) ≥ 50 ml/min within 2 weeks prior to enrollment determined by 24-hour collection or estimated by Cockcroft-Gault formula: CCr male = \[(140 - age) x (wt in kg)\]/\[(Serum Cr mg/dl) x (72)\], CCr female = 0.85 x (CrCl male) 8. Signed, written informed consent prior to completing any study specific procedures 9. Negative pregnancy test for women of child-bearing potential at the time of screening 10. Women of childbearing potential and male participants must agree to use two forms of a medically effective means of birth control throughout their participation in the treatment phase of the study and until 12 months following the last study treatment 11. Chest/Abdominal/Pelvic (CAP) CT/ pelvic MRI done within 8 weeks prior to randomization.
Exclusion criteria
1. Breast-feeding or pregnant 2. Active infection requiring IV antibiotics 7 days before enrollment 3. Prior, unrelated malignancy requiring current active treatment with the exception of cervical carcinoma in situ, basal cell or carcinoma of the skin, invasive cancers with a 5-year disease-free interval, resected cancer of the bladder or low-grade (Gleason 6 or less) prostate cancer 4. Prior history of rectal adenocarcinoma (RAC) 5. Prior history of pelvic radiotherapy for any other type of malignancy 6. Known hypersensitivity or contraindication to any agent in FOLFOX or CAPOX regimen. 7. Because corticosteroids are anti-inflammatory and could interrupt oxidative stress, patients will be excluded unless they are on stable or decreasing corticosteroids dose at the time of randomization.
