• Phase 3 (FREEDOM-1) clinical trial in living donor kidney transplant (LDKT) patients continues; additional data update expected mid-year 2022
• Two Phase 2 (FREEDOM-2 and FREEDOM-3) clinical trials of FCR001 initiated in delayed tolerance and scleroderma
• Robust $244 million cash balance to fund operations through multiple milestones

Talaris Therapeutics, Inc. (Nasdaq: TALS), a late-clinical stage cell therapy company developing therapies with the potential to transform the standard of care in solid organ transplantation and severe immune disorders, today reported financial results for the quarter and year ended December 31, 2021, and provided an update on its business.

“We are excited by what we were able to achieve in 2021 at Talaris,” stated Scott Requadt, Chief Executive Officer of Talaris. “The initial positive data update from our Phase 3 (FREEDOM-1) clinical trial that we provided late last year was a critical step that builds on years of research and development, and provides encouraging signs of FCR001’s potential to induce durable, drug-free immune tolerance in kidney transplant recipients. Inducing immune tolerance for patients without the challenges of taking life-long immunosuppressive drugs is widely seen as the “holy grail” in the transplant field. Taken together with the data from our Phase 2 study, we are encouraged by the body of supportive data that we have produced to date. We are keen to explore the extensibility of our therapy to additional patient populations, starting with our Phase 2 (FREEDOM-2) clinical trial of FCR001 in LDKT delayed tolerance induction and our Phase 2 (FREEDOM-3) clinical trial in our first severe autoimmune disease indication, scleroderma. We look forward to advancing all of our programs and providing additional updates on FREEDOM-1 in 2022.”

Recent Corporate Highlights

• Presented initial positive data update from the ongoing Phase 3 (FREEDOM-1) clinical trial of FCR001 in LDKT. In November 2021, the Company announced that all three evaluable patients treated with FCR001 following kidney transplant demonstrated >50% chimerism at 3-, 6- and 12-month timepoints post-transplant, and that the two patients who were transplanted and dosed more than 12 months prior had successfully discontinued the use of chronic immunosuppressive therapies. The Company continues to enroll patients in this trial and has activated additional sites across the United States.
  
  
• Presented confirmatory data analysis from the Phase II trial demonstrating FCR001 induced durable tolerance in highly mismatched related and unrelated recipients with living donor kidney transplant (LDKT) at the American Society of Hematology (ASH) Annual Meeting in December 2021. High-resolution allele typing at twelve loci found that FCR001 induced durable immune tolerance in highly mismatched related and unrelated recipients based on DNA samples collected in the Phase 2 trial of FCR001 in LDKT recipients. The focus of the analysis was to evaluate the degree of donor/recipient HLA mismatching using high-resolution allele typing and to understand its correlation with the ability to establish durable chimerism in this patient sample. The data analyzed demonstrated that even with a high degree of mismatch, durable chimerism induced by FCR001 allowed for full withdrawal of immunosuppression (IS) in 25 of the 32 subjects evaluated, with time off IS ranging from 3.5 to 11 years.
  
  
• Initiated Phase 2 (FREEDOM-3) clinical trial of FCR001 in scleroderma, its first severe autoimmune disease. FREEDOM-3 is evaluating the safety and efficacy of FCR001 in adults with a severe form of scleroderma, a debilitating, complex and heterogeneous systemic autoimmune disease affecting multiple tissues and organs. In systemic autoimmune diseases, hematopoietic stem cell transplantation (HSCT) has already been observed to be potentially curative. The Company believes that positive proof of concept data from FREEDOM-3 has the potential to both support the use of FCR001 in scleroderma as well as other severe, systemic autoimmune diseases.
  
  
• Initiated Phase 2 (FREEDOM-2) clinical trial of FCR001 in LDKT delayed tolerance induction. FREEDOM-2 is evaluating the potential of FCR001 to induce durable immune tolerance in patients who have previously received a kidney from a living donor (delayed tolerance). Success in FREEDOM-2 would expand the LDKT patient population and market potential for FCR001 by an estimated 6,000-10,000 patients annually.¹
  
  
• Expanded management team with the addition of Andrew Farnsworth as the Chief Human Resources Officer. Mr. Farnsworth has over twenty years of human resource experience in fast-growing private and public companies, bringing with him expertise in leadership development, HR strategy and operations, talent acquisition and retention.
  
  
• Added to the NASDAQ Biotechnology Index. The Company was added to the NASDAQ Biotechnology Index, designed to track the performance of a set of securities listed on the NASDAQ Stock Market® (NASDAQ®) that are classified according to the Industry Classification Benchmark as biotechnology or pharmaceutical companies, in December 2021.

Fourth Quarter and Year-End 2021 Financial Results

• Cash, Cash Equivalents and Marketable Securities: Talaris finished the fourth quarter of 2021 with $244.0 million in cash, cash equivalents and marketable securities compared with $149.5 million as of December 31, 2020.
  
  
• R&D Expenses: Research and development expenses increased to $10.6 million in the fourth quarter of 2021, and $34.3 million for the year ended 2021, compared to $4.4 million and $15.3 million for comparable periods in 2020, respectively. The increase in research and development expenses was primarily due to an increase in employee headcount necessary to support the growth of the Company’s research and development efforts, increased clinical trials costs, increased patient advocacy efforts and an increase in facilities and other expenses.
  
  
• G&A Expenses: General and administrative expenses totaled $3.8 million in the fourth quarter of 2021, and $13.3 million for the year ended 2021, compared to $2.5 million and $7.4 million for comparable periods in 2020, respectively, primarily due to an increase in employee headcount, increased professional fees and an increase in executive risk insurance premiums.
  
  
• Net Loss: The Company reported a net loss of $14.2 million, or $0.35 per share, in the fourth quarter of 2021, and $47.8 million, or $1.64 per share, for the year ended 2021, compared to $6.8 million, or $0.96 per share, and $22.7 million, or $3.40 per share, for comparable periods in 2020, respectively.
