Here are 1-3 brief analogies for TScan Therapeutics (TCRX):

• Like Kite Pharma (now Gilead) or Juno Therapeutics (now Bristol Myers Squibb), but focused on developing TCR-T cell therapies for cancer and infections instead of CAR-T.
• Similar to a company like Moderna or BioNTech, but their proprietary platform discovers and engineers T-cell receptors (TCRs) for treating cancer and chronic infections, rather than developing mRNA-based therapies.

• TCR-T Cell Therapies (e.g., TSC-100, TSC-101, TSC-200, TSC-204): These are a pipeline of T cell receptor (TCR)-engineered T cell (TCR-T) therapies designed to treat various cancers, including hematologic malignancies and solid tumors.
• T-Precision Platform / ImmunoBank: This proprietary technology platform identifies and banks potent, tumor-specific T-cell receptors (TCRs) for use in developing their TCR-T cell therapies.

Major Customers of TScan Therapeutics (TCRX)

TScan Therapeutics (TCRX) is a clinical-stage biopharmaceutical company focused on developing T-cell receptor (TCR) engineered T-cell therapies for the treatment of cancer and other serious diseases. As a company in the drug development phase, it does not sell products directly to individuals (patients). Instead, its primary "customers" are other pharmaceutical or biotechnology companies with whom it forms strategic collaborations for the development, funding, and potential commercialization of its therapeutic candidates.

Their major identified strategic partner and a significant source of funding through collaboration is:

• AstraZeneca (Symbol: AZN)

TScan Therapeutics entered into a significant collaboration and license agreement with AstraZeneca in 2022. This partnership is focused on identifying novel TCR T-cell therapies for five cancer targets. The agreement includes potential upfront payments, research funding, milestone payments, and future royalties, making AstraZeneca a key strategic partner and primary revenue source for TScan Therapeutics at this stage.

The accelerating development and potential widespread adoption of allogeneic (off-the-shelf) T-cell therapies. TScan Therapeutics currently focuses on autologous (patient-specific) T-cell receptor (TCR) engineered T-cell therapies. Allogeneic therapies aim to provide readily available, standardized treatments, potentially overcoming the complex manufacturing, logistical challenges, and high costs associated with autologous therapies. If allogeneic approaches demonstrate comparable efficacy and safety in clinical trials, their inherent advantages in accessibility and scalability could significantly disrupt the market for autologous cell therapies, potentially reducing the addressable market or competitive edge for TCRX's pipeline.

TScan Therapeutics (TCRX) is developing T-cell receptor (TCR)-engineered T cell (TCR-T) therapies for various cancers and is also conducting early-stage research in autoimmune diseases. The addressable markets for their main products or services are as follows:

• For TSC-101, a lead candidate targeting acute leukemia, the potential market is estimated to be $100-$200 million in the U.S.
• TScan Therapeutics targets sizable markets for Acute Myeloid Leukemia (AML) and Human Papillomavirus (HPV)-associated cancers, which are estimated at $1.8 billion and $5.9 billion, respectively. The region for these market sizes is not specified in the provided sources.

The global TCR therapy market, which encompasses the type of therapies TScan Therapeutics is developing, was an estimated US$362 million in 2024 and grew to US$410.6 million in 2025. This market is projected to reach approximately US$1264.73 million by 2034, with a compound annual growth rate (CAGR) of 13.44% between 2025 and 2034. North America accounted for approximately 45% of the TCR therapy market revenue share in 2024.

1. Advancement and Potential Commercialization of TSC-101: TScan's lead T cell receptor (TCR)-engineered T cell (TCR-T) therapy candidate, TSC-101, designed to prevent relapse in patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) after allogeneic hematopoietic cell transplantation, is a primary revenue driver. The company has reached an agreement with the U.S. Food and Drug Administration (FDA) on the pivotal study design for TSC-101. A pivotal trial for TSC-101 is planned for launch in the second quarter of 2026, with a readout supporting full approval anticipated in the second half of 2027. The FDA's Regenerative Medicine Advanced Therapies (RMAT) designation for TSC-100 and TSC-101 could also accelerate the development and approval pathway.
2. Expansion of the Hematologic Malignancies Pipeline: TScan plans to broaden its hematologic malignancies program by submitting Investigational New Drug (IND) applications for two additional TCR-T product candidates in the fourth quarter of 2025. These new candidates aim to expand the human leukocyte antigen (HLA) coverage, potentially increasing the addressable patient population. Phase 1 development for these new candidates is projected to begin in the second half of 2026, subject to additional funding. This expansion could lead to a more robust pipeline and additional revenue streams in the future.
3. Strategic Collaborations: Existing and future strategic collaborations are a significant source of revenue for TScan. The company has a collaboration agreement with Amgen Inc., which has already contributed to substantial increases in collaboration and license revenue. For example, revenue from collaborations and licenses increased to $2.2 million in Q1 2025 from $566,000 in Q1 2024, primarily due to the Amgen partnership. Additional partnerships leveraging TScan's proprietary platform and ImmunoBank of validated TCRs could generate further milestone payments and potential royalties, contributing to revenue growth.
4. Progression of Solid Tumor Therapies through Preclinical Development and Partnerships: While TScan has paused further enrollment in its PLEXI-T solid tumor trial to prioritize its hematologic malignancies program, the company is continuing with preclinical development of in vivo engineering to treat solid tumors. TScan has also partnered with a third party specializing in the development of a lentiviral-based platform for in vivo engineering of T cells. This strategic shift, although leading to a near-term clinical pause, could lay the groundwork for future revenue streams through new collaborations or the advancement of innovative solid tumor programs within the 2-3 year timeframe. Initial safety and efficacy data from the PLEXI-T trial are still expected in Q1 2026, which could validate the platform for future efforts.
