ALI Post Radiation Therapy in Patients With Lung and Esophageal Canter

Phase 2
Active, not recruiting
Conditions
Solid Tumor Malignancies
Interventions
Procedure: Autologous lymphocyte infusion (ALI)
Registration Number
NCT04668833
Lead Sponsor
M.D. Anderson Cancer Center
Brief Summary

The goal of this clinical research study is to learn if giving autologous lymphocyte infusions to patients who are receiving chemotherapy and radiation for non-small cell lung cancer or esophageal cancer is safe and effective.

Detailed Description

The purpose of this study is to determine the safety and preliminary efficacy of un-manipulated autologous lymphocyte infusion (ALI) using the patient's own lymphocytes collected using apheresis, and infused after the completion of radiation/chemoradiation. Primary Objective To investigate the preliminary efficacy of autologous lymphocyte infusion (ALI) in improving the absolute lymphocyte counts in lung and esophageal cancer patients who had undergone chemo-radiation (CRT). Secondary Objectives

1. To evaluate the feasibility and safety of ALI in patients who had undergone chemoradiation.

2. To identify lymphocyte clonal populations in the tissue that are specific for tumor cells

3. To identify immune reconstitution in the peripheral blood shaped by ALI.

4. To conduct clonal analysis using T-cell receptor (TCR) sequencing from tumor and from peripheral blood.

Primary Outcome Measures
NameTimeMethod
To evaluate the absolute lymphocyte counts in lung and esophageal cancer patients who had undergone chemoradiation. (CRT)Baseline to 6 weeks

The primary outcome is the change between the two measures, i.e., absolute lymphocyte counts at week 6 (+/- 14 days) minus baseline ALC, referred as ALC change. Recently, we reviewed 755 patients with stage I-III esophageal carcinoma who received concurrent CRT with or without surgery in 2004-2015 \[1\]. The means of the absolute lymphocyte counts were 1,570 cells/µL (SD=610) and 980 cells/µL (SD=600) at based line and at the first follow-up visit post-CRT, respectively. We incorporate this clinical evidence in our sample size justification.

Secondary Outcome Measures
NameTimeMethod
To evaluate the safety of ALI in patients who had undergone chemoradiation.Baseline to 6 weeks

The method of Thall, Simon and Estey (1995) will be used for toxicity monitoring for this study. Denote the probability of toxicity by PT. We assume a priori, PT \~ beta (0.2, 1.8).

We will stop the arm if Pr(PT\> 0.1 \| data)\>0.80. That is, we will stop the arm for new patient enrollment if at any time during the study, we determine that there is more than 80% chance that the toxicity rate is more than 10%. This toxicity stopping rule will be applied starting from the 10th patient.

To evaluate the feasibility of ALI in patients who had undergone chemoradiation.Baseline to 6 weeks

The number of patients who fail to complete the planned ALI treatment (i.e., inability to collect cell dose or receive cell infusion), will be counted and used as the summary of feasibility for this study. We will evaluate the feasibility of this study for future research and, it will be considered as feasible if less than 5 patients fail planned ALI treatment, while it will be stopped if 10 or more patients fail the planned ALI treatment during any time of the trial. The primary outcome of ALC will be summarized by means and standard deviations along with box-and-whisker plots.
