Effect of Talactoferrin in Adults With Non-Small Cell Lung Cancer

2018年7月3日 更新者:National Cancer Institute (NCI)

An Open Label Pilot Study to Evaluate the Effect on the Immune System of Talactoferrin in Adults With Non-Small Cell Lung Cancer (NSCLC)

Background:

More effective therapies are needed for patients with non-small cell lung cancer (NSCLC) whose disease has advanced or spread beyond the original site following standard treatment.

Talactoferrin is a genetically engineered form of the human protein lactoferrin, found in body secretions such as breast milk, tears and saliva.

In previous studies, talactoferrin improved life span in patients with NSCLC without causing toxic side effects.

Objectives:

To examine the effects of talactoferrin on the immune system and determine its effectiveness in treating NSCLC.

Eligibility:

Patients with advanced NSCLC who have tissue type HLA-A2 and whose cancer has gotten worse following at least one course of treatment.

Design:

Talactoferrin treatment: Patients take liquid talactoferrin twice a day for 12 weeks, followed by 2 weeks off the drug. Treatment may continue in these 14-week cycles depending on the drug side effects and the response of the tumor.

Evaluations: Patients are evaluated at the clinic with a physical examination, check of vital signs and blood tests every 3 weeks.

CT scans: Patients have CT scans to monitor disease before starting treatment, again at 6 weeks and 12 weeks and then every 12 weeks during the duration of treatment.

Apheresis: Quantities of white blood cells called lymphocytes are collected through a procedure called apheresis in order to measure the immune response to treatment. In this procedure, blood is collected through a needle placed in a vein in the arm (similar to donating blood) and circulated through a cell separator machine. The lymphocytes are extracted and the rest of the blood is returned to the body through the same needle.

調査の概要

詳細な説明

Background:

Patients with locally advanced or metastatic NSCLC have a very poor prognosis even with surgery, chemotherapy, and radiation treatments.

Patients who respond to 1st line chemotherapy invariably develop disease progression, and their median survival is between 6-8 months.

Talactoferrin alfa (TLF) is a recombinant human lactoferrin.

TLF displays anti-infective (against bacteria, viruses, protozoa and fungi) and anti-inflammatory properties, anti-tumor activity and anti-asthma properties.

Preclinical studies have demonstrated an increase in cytokines that stimulate both innate and adaptive immunity, as well as increasing the numbers of NK-T cells and CD8+ T-lymphocytes found in Peyer s Patches.

Previous studies in NSCLC have demonstrated safety and evidence of clinical activity.

Objectives:

Primary: To evaluate the effects of administration of talactoferrin to patients with advanced non-small cell lung cancer on the quantitative and functional changes in CD4, CD8, NK, and Treg populations in peripheral blood mononuclear cells (PBMC) and on the levels of cytokines and chemokines in serum.

Secondary: To evaluate clinical response to talactoferrin. To evaluate the safety of talactoferrin.

Eligibility:

Patients with cytologically or histologically confirmed progressive, recurrent, or refractory stage IIIb or IV NSCLC.

Patients must be HLA-A2 positive.

Design:

Single-arm pilot study

Ten patients will be enrolled to receive daily oral talactoferrin (1.5 g/ bid) for up to 12 weeks.

Patients who benefit from treatment will be able to continue on a 12 weeks on 2 weeks off schedule until progression.

Evaluation will be performed every 3 weeks with CT chest, abdomen, and pelvis at baseline, week 6, and week 12.

Immunologic studies (including apheresis) will be performed at baseline, week 6, and week 12.

説明

  • INCLUSION CRITERIA:

Age greater than or equal to 18 years

Histologically or cytologically confirmed progressive, recurrent, or refractory stage IIIB or IV NSCLC; confirmation of pathologic diagnosis to be conducted at the NCI Laboratory of Pathology

Patients may not be eligible for other curative intent treatment (e.g., surgical resection). For the purpose of eligibility for this trial, the above-cited disease states are defined as follows:

  • Progressive NSCLC defined as increasing measurable disease, or the appearance of new measurable disease by RECIST criteria.
  • Recurrent NSCLC defined as the reappearance of measurable disease or the appearance of new measurable disease by RECIST criteria after prior successful treatment or complete response.
  • Refractory NSCLC defined as achieving less than a complete response and having residual measurable disease by RECIST criteria after prior treatment with chemotherapy, targeted or small molecules, monoclonal antibodies, or any combination of these.
  • Patients may enroll who are not candidates for, or who have documented refusal to receive standard therapy (e.g., chemotherapy) for their disease.

HLA-A2 allele

Patient must have evaluable or measurable disease

Total bilirubin less than or equal to 1.5 mg/dL (OR in patients with Gilbert s syndrome, a total bilirubin less than or equal to 3.0)

Creatinine less than 1.5 times Upper Limit of Normal (ULN) if greater than 1.5 times ULN, creatinine clearance on a 24 hour urine collection of greater than 60 mL/min.

AST (SGOT) and ALT (SGPT) less than or equal to 2.5 times the upper limit of normal (ULN); in case of liver metastases less than or equal to 5 x ULN

Eastern Cooperative Oncology Group (ECOG) score 0, 1, or 2

Able to understand and give informed consent
