Summary

• TScan Therapeutics reported its third quarter 2024 financial results, with revenue of $1.0 million, down from $3.9 million in the same period last year due to the timing of research activities with Amgen.
• Research and development expenses increased to $26.3 million from $22.7 million year-over-year, driven by clinical trial costs and increased personnel.
• General and administrative expenses rose to $7.4 million from $5.9 million, also due to increased headcount.
• The company reported a net loss of $29.9 million for the quarter, compared to a $23.0 million loss in the third quarter of 2023.
• As of September 30, 2024, TScan had $271.1 million in cash, cash equivalents, and marketable securities, which they believe will fund operations into the fourth quarter of 2026.
• The company is on track to dose the first patient with multiplex TCR-T therapy and will provide an update on their Phase 1 study by the end of the year.
• TScan is also planning to open expansion cohorts for their ALLOHA trial and report one-year clinical data by the end of 2024.
• An IND filing for a TCR targeting MAGE-A4 is planned by the end of the year, with response data for multiplex therapy anticipated in 2025.

Industry Context

This announcement is relevant to the broader biotechnology industry, particularly companies focused on cell therapies and immuno-oncology. The positive data from the ALLOHA trial and progress in the solid tumor program position TScan as a notable player in the TCR-T therapy space. The company's focus on multiplex therapies and addressing tumor heterogeneity aligns with current trends in cancer treatment.

Comparison to Industry Standards

• The relapse-free survival data in the ALLOHA trial is promising compared to standard hematopoietic cell transplantation outcomes, where relapse rates can be significant.
• Companies like Kite Pharma and Juno Therapeutics, which have developed CAR-T therapies, have shown the potential of cell therapies in hematologic malignancies, but TScan's TCR-T approach targets a different set of antigens and may offer advantages in certain patient populations.
• The development of multiplex therapies to address tumor heterogeneity is a key area of focus in the industry, and TScan's approach is comparable to other companies exploring similar strategies.
• The company's cash runway into the fourth quarter of 2026 is relatively strong compared to many other clinical-stage biotech companies, providing financial stability for ongoing development.

Stakeholder Impact

• Shareholders will likely react positively to the strong clinical data and the company's financial stability.
• Employees may be encouraged by the progress of the clinical programs and the company's growth.
• Patients with hematologic malignancies and solid tumors may benefit from the development of new treatment options.
• The company's collaboration with Amgen and other partners may be strengthened by the positive results.

Next Steps

• The company plans to present updated data from the ALLOHA trial at the ASH Annual Meeting.
• TScan will host a virtual KOL event on December 10th to discuss the ALLOHA trial data and heme development strategy.
• The company is on track to dose the first patient with multiplex therapy and provide an update on their Phase 1 study by the end of the year.
• TScan plans to open expansion cohorts for the ALLOHA trial at the proposed Phase 2 dose level by the end of 2024.
• One-year clinical and translational data on initial patients from the ALLOHA trial will be reported by the end of 2024.
• An IND filing for TCR targeting MAGE-A4 is planned by the end of the year.
• Response data for multiplex therapy is anticipated in 2025.
• The company plans to initiate a registration trial for the ALLOHA program in 2025, pending regulatory feedback.
