Further study details as provided by Ascenta Therapeutics:
Primary Outcome Measures:
- Phase 1: Safety and tolerability of AT-101 in combination with chemoradiotherapy, and determine a dose for Phase 2. Phase 2: Determine the pathologic complete response (pathCR) rate and to correlate tumor biomarker expression with clinical response. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- To assess the safety and toxicity of chemoradiotherapy and AT-101 in patients with esophageal or gastroesophageal junction cancer. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Intervention Details:
-
Drug: AT-101
Patients will receive AT-101 starting at 10 mg once daily for 5 of 7 days in conjunction with RT (50.4 Gy for 28 fractions) for approximately 5.5 weeks. Concurrently, patients will receive docetaxel (20 mg/m2) IV weekly (Monday) and 5-fluorouracil (300 mg/m2) as a 24 hour continuous infusion for 5 of 7 days (Monday-Friday) of each RT week for approximately 5 weeks. Patients will continue for full 5.5 weeks unless unacceptable toxicity occurs.
Eligibility| Ages Eligible for Study: | 18 Years and older |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
Criteria
Inclusion Criteria:
- Male or female patients age ≥18 years
- Histologically confirmed primary (non-recurrent) adenocarcinoma (AC) or squamous cell carcinoma of the esophagus or AC of the gastroesophageal (GE) junction.
- For Phase 1: Phase 1 patients must have unresectable disease (Stage II to IVa). A patient can be unresectable for medical reasons or technical reasons but eligible for chemoradiation.
- For Phase 2: Phase 2 patients must have resectable cancer defined as: T2, T3, N0; OR T1-3, N+
- Patients must have archived tumor tissue to correlate tumor biomarker expression with clinical response. Availability of tumor specimens in paraffin blocks or at least two unstained slides must be confirmed prior to study entry. Results will not be used to determine patient eligibility for the study.
- ECOG performance status 0-1
- Adequate hematologic function
- Adequate liver and renal function
- Ability to swallow and retain oral medication.
Exclusion Criteria:
- Patients with distant metastasis, including M1b lymph node status. (M1b status allowed on Phase I only for patients appropriate for chemoradation). Lymph nodes suspicious of M1b status by diagnostic imaging must be verified by fine-needle aspiration cytology. (Phase 2 only)
- For Phase 2: Patients with positive pleural, pericardial, or peritoneal cytology.
- For Phase 2: Patients with carcinoma of the cervical esophagus.
- For Phase 2: Patients with clinical evidence of metastasis to cervical or supraclavicular lymph nodes.
- Prior chemotherapy or radiotherapy for esophageal or gastroesophageal junction cancer. Phase 1 patients with prior chemotherapy are permitted to enter.
- Prior radiotherapy that would overlap the anticipated study treatment fields or radiotherapy to >30% of the marrow cavity (no prior chest irradiation).
- Patients with malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel are excluded. Subjects with ulcerative colitis, inflammatory bowel disease, or partial or complete small bowel obstruction are also excluded.
- Pregnant or nursing females. Fertile patients (male and female) must use effective contraception.
