The Ave-CRT Study for Newly Diagnosed Metastatic Esophageal Squamous Cell Carcinoma

Chemotherapy/Avelumab Plus Radiotherapy to Primary Esophageal Tumor for Newly Diagnosed Metastatic Esophageal Squamous Cell Carcinoma: The Ave-CRT Study

This is a single institutional, single arm, open labeled phase II study to assess the overall radiographic response of adding Avelumab to chemotherapy and palliative radiotherapy in patients with metastatic advanced esophageal squamous cell carcinoma.

Study Overview

• Status: Enrolling by invitation
• Conditions: Metastatic Esophageal Squamous Cell Carcinoma; Esophageal Tumor
• Intervention / Treatment: Drug: Avelumab

Detailed Description

Avelumab belongs to the group of immune checkpoint blockade cancer therapies. Avelumab binds to the programmed death-ligand 1 (PD-L1) and therefore inhibits binding to its receptor programmed cell death 1 (PD-1). In the case of avelumab, the formation of PD-1/PDL1 ligand pairs is blocked and CD8+ T cell immune response should be increased. This study comprises 2 phases, the concurrent immune-chemoradiotherapy (Ave-PF-CRT) phase and the immune-chemotherapy (Ave-PF) phase. In the immune-chemoradiotherapy phase, patients are treated with PF-CRT and concomitant Avelumab. In the immune-chemotherapy phase, patients are treated with PF plus Avelumab. Overall radiological response, time to progression, overall survival and adverse events will be evaluated. Subjects' health-related quality of life will be assessed as well.

Exclusion Criteria:

• Patients fulfill any of the following criteria will be excluded from this trial

  1. Prior radiotherapy to head and neck, chest, or abdomen
  2. Tumor invasion to adjacent structures (T4 lesion)
  3. Adenocarcinoma of esophagus or gastroesophageal junction.
  4. No measurable metastatic target lesion(s) by RECIST criteria

  8. Current use of immunosuppressive medication, EXCEPT for the following:

     1. intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection)
     2. systemic corticosteroids at physiologic doses '≤ 10 mg/day of prednisone or equivalent
     3. steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication).
  9. Active autoimmune disease that might deteriorate when receiving an immuno-stimulatory agent. Patients with diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid diseases not requiring immunosuppressive treatment are eligible.

  10. Severe, active comorbidities which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and adverse events of the protocol, or limit compliance with study requirements, defined as follows:

      1. Uncontrolled active infection requiring intravenous antibiotics at the time of registration
      2. Transmural myocardial infarction < 6 months prior to registration
      3. Unstable angina or congestive heart failure requiring hospitalization < 6 months prior to registration
      4. Life-threatening uncontrolled clinically significant cardiac arrhythmias
      5. Cerebral vascular accident/stroke (< 6 months prior to enrollment)
      6. Congestive heart failure (≥ New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication.
      7. Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects
      8. Chronic obstructive pulmonary disease exacerbation or other respiratory illness including pulmonary fibrosis requiring hospitalization or precluding study therapy at the time of registration
      9. Uncontrolled psychiatric disorder including recent (within the past year) or active suicidal ideation or behavior
      10. Laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results
      11. Immune colitis, inflammatory bowel disease, immune pneumonitis
  11. Known history of testing positive for HIV or known acquired immunodeficiency syndrome."
  12. Hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or HCV RNA if anti-HCV antibody screening test positive)
  13. Vaccination within 4 weeks of the first dose of avelumab and while on trials is prohibited except for administration of inactivated vaccines
  14. Known prior severe hypersensitivity to investigational product or any component in its formulations, including known severe hypersensitivity reactions to monoclonal antibodies (NCI CTCAE v4.03 Grade ≥ 3)"
  15. Women of childbearing potential and male participants who are sexually active and not willing/able to use medically acceptable forms of contraception; this exclusion is necessary because the radiation treatment involved in this study may be significantly teratogenic

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
overall radiographic response	overall radiographic response at six-month will be determined by iRECIST	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Best radiographic response	The best radiographic response of in-field irradiated and out-field non-irradiated (abscopal effect) target lesions will be determined by iRECIST.	up to 2 years
Progression-free survival	Kaplan-Meier survival estimator will be used to determine the median time to progression for study population (along with 95% confidence interval). The log-rank test will be performed to evaluate the equality of survivor functions across stage, and other covariates of interest on progression-free survival.	up to 2 years
Overall survival	Kaplan-Meier survival estimator will be used to determine the median time to death for study population (along with 95% confidence interval). The log-rank test will be performed to evaluate the equality of survivor functions across stage, age, and other covariates of interest on overall survival.	up to 2 years
Frequency of adverse events	The tabulations will count the number of subjects reporting individual adverse events. Adverse events are collected/assessed during treatment period (every week in the Ave-PF-CRT phase [one cycle, 4 weeks], the first and third week of each cycle in the Ave-PF phase [5 cycles, each cycle is 4 weeks]), every 3 months during evaluation, and in 2 years.	up to 2 years
Heath-related quality of life	The self-reported health-related quality of life specific to esophageal cancer is a 44-item functioning scale captured using the Functional Assessment Of Cancer Therapy-Esophageal (FACT-E) Traditional Chinese version. Each question uses a 5-point Likert scale ranging from 0 to 4, and higher scores indicate better quality of life (0-176 for FACT-E total score). The FACT-E is assessed before treating is given, in the third week of Ave-PF-CRT phase (one cycle, 4 weeks), in the first week of every cycle (4 weeks) during the Ave-PF phase (5 cycles), and in the 2 years. Changes in total score of FACT-E from baseline to each assessment point will be calculated.	up to 2 years
New metastasis-free survival	Kaplan-Meier survival estimator will be used to determine the median time to development of new metastasis for study population (along with 95% confidence interval). The log-rank test will be performed to evaluate the equality of survivor functions across stage, and other covariates of interest on new metastasis-free survival.	up to 2 years
