Overview

Tr1X focuses on cellular immunotherapies for autoimmune and inflammatory diseases. Using a proprietary platform, it creates first-in-class cell therapy products that aim to rebalance the immune system and restore homeostasis, achieving long-term tolerance. The company develops and commercializes these therapies, generating revenue through partnerships, licensing, and direct sales, with a business base in La Jolla, CA. How it works: the core product is a cell therapy designed to modulate immune responses so the body reaches stable immune balance rather than ongoing suppression. This differs from many competitors by emphasizing durable immune tolerance via a proprietary platform and by pursuing partnerships and licensing to bring therapies to healthcare providers and patients. The goal is to deliver durable immune tolerance for autoimmune and inflammatory diseases through first-in-class cell therapies.

Simplify's Take

What believers are saying

  • FDA cleared INDs for TRX103 in GvHD and TRX319 in MS, trials advancing with positive safety data.
  • Secured $75M Series A from Column Group and $50M financing plus $8M CIRM grant.
  • San Diego biotech hub provides talent access near UCSD and 400+ local companies.

What critics are saying

  • Manufacturing scale-up fails, halting TRX103 and TRX319 GMP production within 12-24 months.
  • TRX319 Phase 1 triggers cytokine release safety signal, terminating MS program in 6-18 months.
  • Regeneron and AstraZeneca displace Tr1X with faster Treg efficacy readouts in 18-36 months.

What makes Tr1X unique

  • Tr1X engineers allogeneic Tr1 Treg cells mimicking natural Tr1 cells for superior inflammation homing.
  • Proprietary platform enables scalable off-the-shelf CAR-Treg therapies like TRX319 for progressive MS.
  • Founded on Dr. Maria Grazia Roncarolo's Tr1 cell discovery, first in clinical trials.

Tr1X Awarded $8 Million Cirm Grant To Support Trx103 Phase 1/2A Clinical Trial For Graft-Versus-Host Disease

SAN DIEGO, April 04, 2025 (GLOBE NEWSWIRE) -- Tr1X, Inc. (pronounced "Trix"), a clinical-stage biopharmaceutical company developing first-in-class allogeneic engineered Treg and CAR-Treg cell therapies with the potential to cure autoimmune and inflammatory diseases, today announced that the California Institute for Regenerative Medicine (CIRM) has awarded the Company an $8 million grant to support its ongoing Phase 1/2a clinical trial of TRX103, an engineered Tr1 Treg cell therapy for use in the prevention of graft-versus-host disease (GvHD) in blood cancer patients undergoing mismatched stem cell transplants. This award follows a $4 million CIRM grant received by Tr1X in early 2024 for late-stage preclinical research that helped to advance TRX103 to human trials. The TRX103 Phase 1/2a clinical trial is being led by Maria Grazia Roncarolo, MD, co-founder, president and head of RD at Tr1X, with patients enrolling at leading stem cell transplant centers across the country. The trial is designed to treat patients receiving a mismatched or haploidentical transplant with a one-time infusion of TRX103. The Company has reported positive initial persistence and safety data in the first two patient cohorts, with additional data anticipated to be reported in 2025
