TScan Therapeutics, Inc. (TCRX) is a clinical-stage biotechnology company at the forefront of developing innovative T cell receptor (TCR)-engineered T cell (TCR-T) therapies for the treatment of various cancers. The company's novel approach leverages its proprietary platform technologies to discover and engineer highly potent TCRs, positioning it as a leader in the rapidly evolving field of immuno-oncology.
Business Overview and History
Established in 2018, TScan Therapeutics was founded on the premise that by learning from patients who are winning their fight against cancer, the company could develop effective TCR-T therapies to treat those who are not. The company's origins trace back to the groundbreaking research conducted at the Brigham and Women's Hospital, where the founders identified and patented the technology underlying TScan's proprietary TargetScan and ReceptorScan platforms.
In its early years, TScan focused on raising capital, obtaining financing, filing and prosecuting patent applications, organizing and staffing the company, and conducting research and development activities related to identifying novel targets and developing TCR-T therapy candidates. The company has primarily funded its operations through sales of capital stock, revenue received under collaboration agreements, and a debt facility.
In 2020, TScan entered into a Collaboration and License Agreement with Novartis Institutes For Biomedical Research, Inc. to collaborate on research efforts to discover and develop novel TCR-T therapies. This agreement concluded in early 2023. Following this, in May 2023, TScan entered into a new Collaboration Agreement with Amgen Inc. to identify antigens recognized by T cells in patients with Crohn's disease.
Despite being in the early stages of development, TScan has made significant progress in advancing its pipeline. The company has cleared Investigational New Drug (IND) applications for several of its product candidates and initiated clinical trials. However, TScan has continued to incur significant operating losses since its inception as it focuses on its research and development efforts.
These platforms have enabled TScan to build a robust pipeline of TCR-T therapy candidates targeting both hematologic malignancies and solid tumors. The company's lead product candidates, TSC-100 and TSC-101, are in development for the treatment of patients with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and myelodysplastic syndromes (MDS) undergoing allogeneic hematopoietic cell transplantation (HCT). These product candidates target the antigens HA-1 and HA-2, respectively, which were first identified in patients with exceptional responses to HCT-associated immunotherapy.
Additionally, TScan has advanced six TCR-T therapy candidates into Phase 1 clinical trials for the treatment of solid tumors, including TSC-203-A0201 targeting PRAME, TSC-200-A0201 targeting HPV16, and TSC-201-B0702 targeting MAGE-C2. The company is also developing a multiplex TCR-T therapy approach to address the challenge of solid tumor heterogeneity, where patients are treated with a combination of up to three highly active TCR-T therapy candidates customized based on the targets expressed in their tumors and the HLA genes that are still intact.
Financials and Liquidity
As of June 30, 2024, TScan reported cash, cash equivalents, and marketable securities of $297.70 million, which the company believes will enable it to fund its current operating plan into the fourth quarter of 2026. For the six months ended June 30, 2024, the company reported a net loss of $61.80 million, compared to a net loss of $46.60 million for the same period in the prior year. The increase in net loss was primarily attributable to a $8.70 million increase in research and development expenses, driven by costs associated with the company's ongoing clinical trials, as well as a $0.60 million increase in general and administrative expenses.
The company's balance sheet remains strong, with a current ratio of 8.14, a quick ratio of 8.14, and a cash ratio of 4.97, indicating a robust liquidity position. TScan's operating cash flow for the six months ended June 30, 2024, was negative $55.49 million, while its free cash flow was negative $54.95 million.
In December 2024, TScan announced a $30 million registered direct offering at a 37% premium to its then-current stock price, further bolstering its financial position. Additionally, in December 2024, the company refinanced its existing convertible debt facility with a $52.5 million term loan from Silicon Valley Bank, extending the loan maturity to 2029.
For the most recent quarter (Q2 2024), TScan reported revenue of $665,000, a net loss of $35,809,000, operating cash flow of negative $27,412,000, and free cash flow of negative $28,300,000. The decrease in net income, operating cash flow, and free cash flow was primarily due to increased R&D spending to advance the company's TCR-T therapy candidates through clinical trials.
The company's debt-to-equity ratio stands at 0.40, with cash and cash equivalents of $242.16 million. TScan has a $52.5 million term loan facility with Silicon Valley Bank, of which $32.5 million was drawn at closing to retire existing debt.
Recent Developments and Milestones
In 2024, TScan made significant advancements in its clinical pipeline and operational initiatives:
1. ALLOHA™ Phase 1 Heme Trial: The company presented updated data from the ongoing ALLOHA™ Phase 1 trial of TSC-100 and TSC-101 at the 66th American Society of Hematology (ASH) Annual Meeting. The data showed that all TSC-treated patients were relapse-free and minimal residual disease (MRD) negative as of the data cutoff, and TSC-100 and TSC-101 demonstrated the potential to reduce relapse rates and increase relapse-free survival in patients with AML, ALL, or MDS undergoing allogeneic HCT with reduced intensity conditioning.
2. PLEXI-T™ Phase 1 Solid Tumor Trial: TScan received clearance from the FDA for its seventh TCR-T therapy candidate, TSC-202-A0201 targeting MAGE-A4 on HLA-A*02:01, to enter its PLEXI-T™ Phase 1 solid tumor trial. The company also presented three abstracts at the Society for Immunotherapy of Cancer (SITC) 39th Annual Meeting, highlighting its progress in the solid tumor program.
3. Operational Milestones: In addition to its clinical advancements, TScan was named one of the Top Places to Work in Massachusetts by The Boston Globe for three consecutive years, underscoring its commitment to fostering a positive and collaborative work environment.
Risks and Challenges
As a clinical-stage biotechnology company, TScan faces a range of risks and challenges common to the industry, including:
1. Clinical Development Risks: The successful development and regulatory approval of TScan's product candidates are subject to significant uncertainty, as the company must demonstrate the safety, potency, and purity of its TCR-T therapies through rigorous preclinical studies and clinical trials.
2. Manufacturing Challenges: The manufacture of TCR-T therapies is a complex and highly regulated process, and TScan's ability to scale up and consistently produce its product candidates to the required quality standards is crucial to its success.
3. Competitive Landscape: TScan operates in a highly competitive space, with other biotechnology companies and larger pharmaceutical players also developing innovative TCR-T and other cell-based therapies.
4. Regulatory Hurdles: The regulatory approval process for TCR-T therapies is evolving, and TScan must navigate the complex and often uncertain regulatory landscape to bring its products to market.
5. Financing Needs: As a clinical-stage company, TScan will likely require additional financing to support its ongoing research, development, and manufacturing efforts, which could dilute its existing shareholders.
Despite these challenges, TScan's strong cash position, robust pipeline, and experienced management team position the company well to continue advancing its innovative TCR-T therapies and addressing the significant unmet needs in cancer treatment.
