Winston Score History

The full picture

TScan Therapeutics is a clinical-stage biotechnology company focused on developing T-cell receptor (TCR) therapies to treat cancer. Instead of using traditional drugs, it engineers patients' own immune cells to recognize and attack cancer cells. The company's main focus is on blood cancers, particularly in patients who have received stem cell transplants.

TScan does not yet sell any approved products, so it earns no product revenue. Its income comes primarily from research collaborations and grants. The company operates mainly in the United States and is small, with a market cap near zero, reflecting the early and high-risk nature of its pipeline. Its proprietary platform for identifying T-cell receptors is its key differentiator, but like most clinical-stage biotechs, it burns cash steadily while funding trials. The biggest risk is that its lead programs could fail in clinical trials, which would likely exhaust its remaining capital and threaten the company's survival.

Growth Profile

When traditional metrics don't capture the full picture, these are the signals growth stock investors use instead.

Cash watch

TScan Therapeutics has less than a year of cash at its current burn rate. Growth investors should watch for potential share dilution from future fundraising — that directly reduces your ownership.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
