Talaris Therapeutics Announces Third Quarter 2021 Financial Results and Provides Business Update

November 12, 2021

Provided initial clinical update from its Phase 3 (FREEDOM-1) clinical trial evaluating FCR001 in living donor kidney transplant patients

Initiated Phase 2 (FREEDOM-2) clinical trial for FCR001 in delayed tolerance induction patients

BOSTON and LOUISVILLE, Ky., Nov. 12, 2021 (GLOBE NEWSWIRE) -- 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, certain severe autoimmune diseases, and certain severe non-malignant blood, immune and metabolic disorders, today reported financial results for the three- and nine-month periods ended September 30, 2021, and provided an update on its business.

“We made significant progress in the quarter, providing our first Phase 3 clinical update in living donor kidney transplant (LDKT) patients, and presenting additional long-term follow-up data from our Phase 2 trial in the same patient population at the 2021 American Society of Nephrology meeting,” stated Scott Requadt, Chief Executive Officer of Talaris. “Our clinical evidence to date suggests that those patients who achieve >50% T cell chimerism at 3, 6 and 12 months after the administration of FCR001 are likely to be able to be durably weaned from chronic immunosuppression at one year after transplant. We were pleased to report, in our first clinical update from the Phase 3 FREEDOM-1 trial, that all patients who have reached the three-month time point post-transplant have achieved sustained chimerism. These results continue to give us confidence that FCR001 has the potential to transform the standard of care in solid organ transplantation.”

Mr. Requadt continued: “In addition, we are advancing our pipeline with the initiation of our FREEDOM-2 Phase 2 trial of FCR001 to assess its potential to induce durable immune tolerance in LDKT patients who received their kidney transplant up to 12 months prior to administration of our investigational therapy. We also remain on track to initiate another Phase 2 trial in our first severe autoimmune disease indication, scleroderma, before year-end.”

Corporate Highlights

  • Presented initial clinical update on safety and chimerism data from the Phase 3 FREEDOM-1 trial with living donor kidney transplant (LDKT) patients.
    • FREEDOM-1 is a randomized, controlled, open-label Phase 3 registrational trial of FCR001 in 120 adult LDKT recipients in the United States. The primary endpoint of FREEDOM-1 is the proportion of LDKT recipients treated with FCR001 who are free from chronic immunosuppression (IS), without proven biopsy rejection (BPAR), at month 24 post-transplant.
    • The initial data presented includes a total of 11 LDKT donor-recipient pairs enrolled from a total of 5 clinical sites. Five of the seven patients randomized to receive FCR001 had been dosed as of the data cut-off date and three patients were dosed at least three months prior to the data cut-off date and were evaluated for safety, chimerism, and ability to wean patients off chronic IS.
    • All three patients dosed at least three months prior to the data cut-off date successfully achieved >50% chimerism. Chimerism is a condition whereby both the donor’s and the recipient’s hematopoietic stem cells co-exist in the recipient’s bone marrow and was correlated strongly in the Company’s Phase 2 trial with the transplant recipient’s ability to be durably weaned from chronic IS approximately one year after transplant, without subsequent graft rejection in the Company’s Phase 2 trial.
    • Both patients dosed at least 12 months prior to the data cut-off date achieved and maintained >50% T-cell chimerism at each of the 3-, 6- and 12-month timepoints and have discontinued their use of chronic IS.
    • The adverse events (AEs) and serious adverse events (SAEs) observed to date in the FREEDOM-1 study were consistent with kidney and stem cell transplantation involving non-myeloablative conditioning and what was observed in the Phase 2 study. No events occurred to cause the Data Safety Monitoring Board (DSMB) to stop or modify the study protocol, nor was any stopping rule triggered. Furthermore, no FCR001-dosed patients in the Phase 3 study experienced BPAR or developed donor-specific antibodies (DSA), the presence of which post-transplant predicts an increased risk for antibody-mediated rejection of the donated organ.
  • Presented updated long-term follow-up data from its Phase 2 LKDT study at the 2021 American Society of Nephrology meeting (ASN). At ASN, the Company presented updated long-term follow-up data from patients in its Phase 2 LDKT study. Data presented showed that 26 of 26 patients (100%) weaned off IS had continued to remain off chronic IS for the duration of their follow-up (a median >6 years and the longest >12 years post-treatment) without rejection of their donated kidney. Six of these transplant recipients have now exceeded 10 years off all chronic IS without BPAR at the time of the presentation. Through June 11, 2021, the date of the most recent DSMB meeting for the Phase 2 study, there have been no additional AEs or SAEs reported since the prior Phase 2 data cut-off date that were determined to be related to FCR001.

  • Presented potential urinary biomarker of immune quiescence at ASN. Talaris presented findings of urinary mRNA profiling performed in a subgroup of Phase 2 LDKT patients who were tolerized to their donated kidney and a cohort of biopsy-matched, standard of care, LDKT recipients on chronic IS. These data may provide further support that these patients may have been tolerized to their donated kidney due to potential signals of greater immune quiescence in the kidneys of tolerized patients, as compared to the cohort of the biopsy-matched standard of care kidney transplant patients.

  • Initiated patient screening of Phase 2 (FREEDOM-2) clinical trial of FCR001 in delayed tolerance induction. Northwestern University is the first FREEDOM-2 clinical site to have been activated and has now begun screening for eligible patients. Additional sites are expected to be activated in 2022. This trial will explore the safety and efficacy of FCR001 to induce immune tolerance to a transplanted kidney in patients who received a kidney transplant from a living donor up to a year prior to administration of FCR001.

Third Quarter 2021 Financial Results

  • Cash, Cash Equivalents and Marketable Securities: Talaris finished the third quarter of 2021 with $254.7 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 $9.2 million in the third quarter of 2021, from $4.0 million in the third quarter of 2020. 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 and an increase in facilities and other expenses.

  • G&A Expenses: General and administrative expenses totaled $3.9 million in the third quarter of 2021, up from $2.2 million in the third quarter of 2020, 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 $12.9 million, or $0.32 per share, in the third quarter of 2021, compared with a net loss of $6.4 million, or $0.94 per share, in the third quarter of 2020.
