简要总结

Objective:

To collect information on how often a solid tumor cancer might lose the Human Leukocyte Antigen (HLA) by next generation sequencing and perform apheresis to collect and store an eligible participant's own T cells for future use to make CAR T-Cell therapy for their disease treatment.

Design:

This is a non-interventional, observational study to evaluate participants with solid tumors with a high risk of relapse for incurable disease. No interventional therapy will be administered on this study. Some of the information regarding the participant's tumor analysis may be beneficial to management of their disease. Participants that meet all criteria may be enrolled and leukapheresed (blood cells collected). The participant's cells will be processed and stored for potential manufacture of CAR T-cell therapy upon relapse of their cancer.

详细描述

Background:

Human Leukocyte Antigen (HLA) is a protein on the outside of cells that allows the immune system to recognize it's own cells as normal and leave them alone or respond if infected with a virus or bacteria, or a tumor cell. HLA might not be expressed normally on cancer cells. This may be why cancer can grow undetected by the immune system and is referred to as a tumor escape mechanism. Tumor escape can occur for many reasons, but one reason is Loss of Heterozygosity (LOH). LOH is the loss of one of the genes that encodes HLA protein. A2 Biotherapeutics, Inc. (A2 Bio) is developing therapies to recognize, target, and kill cancer cells that do not express HLA normally, and minimize any damage to normal cells that express normal HLA.

Once participants are identified as having LOH on their tumors, apheresis, a procedure to separate and collect white blood cells will be performed. It is the first required step in manufacturing CAR T-cell therapy. The collected T cells will be stored for patients that are likely to benefit from CAR T-cell therapy during their disease care.

Study Design:

Approximately 3000 participants will be screened for part 1 of the study, including HLA typing, approximately 1500 participants will have NGS testing on their tumor samples and be followed for up to 2 years on the study, and up to 500 participants will be screened for part 2 of the study and enrolled if eligible and apheresed and be followed for up to 2 years on the study.

  • Participants who have received any cancer therapy on any investigational therapy for any indication, including but not limited to chemotherapy, small molecules, monoclonal antibodies, or radiotherapy (with bone marrow impact) within 2 weeks of planned apheresis or 3 half-lives, whichever is shorter.
  • Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) at study enrollment necessitating specific treatment, or any major episode of infection requiring treatment with Intravenous (IV) antimicrobials (e.g., IV antibiotics) or hospitalization (relating to completion of antibiotic course).
  • Has known active central nervous system metastases. Subjects with previously treated brain metastases may participate upon medical monitor agreement.
  • In the Investigator's judgement, any other condition or reason the subject would not complete the required study visits and procedures, and follow up visits, or comply with the study requirements for participation.
