• Multiple presentations pending at upcoming American Transplant Congress (ATC), as well as concurrent update on ongoing Phase 3 (FREEDOM-1) clinical trial in living donor kidney transplant (LDKT) patients
  
• Presented data on COVID-19 outcomes among kidney transplant patients treated with FCR001
• Strong $225.5 million cash balance to fund operations

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 and blood disorders, today reported financial results for the three-month period ended March 31, 2022, and provided an update on its business.

“It has been a productive start to the year,” stated Scott Requadt, Chief Executive Officer of Talaris. “We recently presented at the 2022 Cutting Edge of Transplantation (CEoT) meeting and are excited to present five abstracts at the upcoming American Transplant Congress annual meeting that continue to highlight the growing body of scientific evidence supporting FCR001’s potential to achieve durable immune tolerance in kidney transplant patients. Alongside the meeting, we also plan to provide an interim update on our open-label FREEDOM-1 clinical study. With a strong balance sheet to support our development initiatives, we look forward to reporting on additional progress in our pipeline programs.”

Corporate Highlights

• Updated data from the Phase 3 (FREEDOM-1) clinical trial of FCR001 in living donor kidney transplant (LDKT) to be presented mid-year. FREEDOM-1 is a randomized, controlled, open-label, multi-center Phase 3 registrational trial of FCR001 in 120 adult LDKT recipients in the United States. 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. The Company will provide a further update on this trial next month at ATC.
  
  
• Multiple abstracts to be presented at the American Transplant Congress (ATC) taking place June 4-8, 2022. Five abstracts will be presented including new long-term follow-up data from the successful Phase 2 study of FCR001 in LDKT patients. In addition, the Company is presenting a poster reflecting the results of a retrospective real-world evidence analysis of the long-term health outcomes of Phase 2 patients treated with FCR001 compared to a cohort of matched patients treated with standard of care.
  
  
• Presented data on COVID-19 outcomes among kidney transplant patients treated with FCR001. In April, the Company presented data at the 2022 Cutting Edge of Transplantation (CEoT) meeting organized by the American Society of Transplantation highlighting that a low rate of COVID-19 infection was observed in vaccinated, durably chimeric patients off immunosuppression. No evidence of acute kidney injury or impaired renal function was seen in these patients and no patients lost chimerism as a result of COVID-19 vaccination or infection. The Company will present additional updated data on COVID-19 outcomes among kidney transplant patients treated with FCR001 at ATC.
  
  
• 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 The Company recently activated its second trial site for FREEDOM-2.
  
  
• Phase 2 (FREEDOM-3) clinical trial of FCR001 in scleroderma. 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.

First Quarter Financial Results

• Cash, Cash Equivalents and Marketable Securities: Talaris finished the first quarter of 2022 with $225.5 million in cash, cash equivalents and marketable securities compared with $140.1 million as of March 31, 2021.
  
  
• R&D Expenses: Research and development expenses increased to $14.2 million in the first quarter of 2022, up from $6.5 million in the first quarter of 2021. 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 for increased enrollment and additional site activations, and increases in facilities and other expenses.
  
  
• G&A Expenses: General and administrative expenses totaled $4.2 million in the first quarter of 2022, up from $2.5 million in the first quarter of 2021, 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 $18.3 million, or $0.45 per share, in the first quarter of 2022, compared with a net loss of $9.3 million, or $1.30 per share, in the first quarter of 2021.
