WALTHAM, Mass., Aug. 10, 2023 (GLOBE NEWSWIRE) -- TScan Therapeutics, Inc. (Nasdaq: TCRX), a clinical-stage biopharmaceutical company focused on the development of T cell receptor-engineered T cell therapies (TCR-Ts) for the treatment of patients with cancer, today reported financial results and provided a corporate update for the second quarter ended June 30, 2023.
“The success of the second quarter has been a testament to the hard work here at TScan over the last six months,” said Gavin MacBeath, Ph.D., Chief Executive Officer. “We are encouraged by the initial clinical data from our heme malignancies program and look forward to reaching the recommended Phase 2 dose for both TSC-100 and TSC-101 and providing a more extensive update by the end of this year. We continue to successfully enroll and treat patients in the dose escalation portion of the Phase 1 study and have not observed any dose limiting toxicities to date. Both TCR-T product candidates are now proceeding through dose level 2. With regards to the solid tumor program, we continue to focus our efforts on populating the ImmunoBank with TCR-Ts that address different targets and diverse HLA types to enable tailored, multiplexed TCR-T therapies. Following the close of an underwritten public offering in June, we are well capitalized to execute on upcoming anticipated milestones into 2026, by which time we expect to report data for both clinical programs.”
- In May 2023, the Company presented preliminary data from its ongoing multi-arm Phase 1 clinical trial evaluating TSC-100 and TSC-101, two different TCR-T cell therapy product candidates that are designed to treat residual disease and prevent relapse following hematopoietic cell transplantation in patients with acute myeloid leukemia (AML), myelodysplastic syndromes (MDS), or acute lymphocytic leukemia (ALL). Data were presented at the American Society of Gene & Cell Therapy (ASGCT) 26th Annual Meeting 2023. Both TSC-100 and TSC-101 showed markers of T cell activation and proliferation in patients, with no dose limiting toxicities. The Company also reported donor chimerism data for three patients. Two medium-risk MDS patients in the control arm showed incomplete donor chimerism, whereas the high-risk MDS patient in the TSC-101 arm showed complete donor chimerism within three weeks of receiving the engineered TCR-T cell product. The study is now advancing to dose level 2 in both the TSC-100 and TSC-101 arms. TScan remains on track to reach the recommended Phase 2 dose for both products and report interim clinical data for the program by the end of 2023.
- The Company recently announced the U.S. Food and Drug Administration (FDA) has cleared its investigational new drug (IND) application for TSC-200-A0201, a TCR-T targeting the E7 protein of human papillomavirus 16 (HPV16). TSC-200-A0201 is the third TCR-T cleared to initiate clinical development in the Company’s solid tumor program. TSC-204-A0201 and TSC-204-C0702, which target MAGE-A1 presented on HLA types A*02:01 and C*07:02, respectively, were cleared earlier this year. TScan is on-track to initiate clinical development of all three TCR-T candidates in a multi-arm Phase 1 basket study in the second half of 2023. The clinical trial, which has received clearance from the FDA, is designed to assess the safety and efficacy of each candidate individually at two different dose levels, and then to assess custom combinations of TCR-Ts at dose levels 3 and 4 in patients that qualify to receive more than one therapeutic candidate. TScan plans to file INDs for three additional TCR-T candidates by year end, including a TCR-T that targets the tumor-associated antigen PRAME. Upon FDA clearance, these candidates will be introduced into the ongoing clinical trial, thereby increasing patient eligibility for multiplexed TCR-T cell therapy.
- During the second quarter, TScan announced the closing of an underwritten public offering with net proceeds of approximately $134.7 million. The Company intends to use the proceeds for general corporate purposes. Following this offering, the Company expects that its existing cash and cash equivalents, along with proceeds from the collaboration agreement with Amgen, will fund its operating expenses and capital expenditure requirements into 2026.
- In June 2023, TScan presented a trial in progress poster for its solid tumor program at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting. A copy of the poster can be found on the “Publications” section of the Company’s website at www.tscan.com.
Upcoming Anticipated Milestones
Heme Malignancies Program:
- Expects to reach the recommended Phase 2 dose for both TSC-100 and TSC-101 and report interim clinical data for the program by the end of 2023.
- Plans to complete Phase 1 dosing and report prevention of relapse data in 2024.
Solid Tumor Program:
- Anticipates further expansion of the ImmunoBank with the recent filing of an IND for TSC-203-A0201, an HLA-A*02:01-restricted TCR targeting PRAME, and IND filings for two additional TCRs by year-end.
- Plans to initiate Phase 1 solid tumor clinical study in the second half of 2023 and anticipates sharing preliminary data by the end of 2023.
- Expects to report initial multiplexed therapy data for its first combinations of TCR-Ts under T-Plex, as well as response data for singleplex cohorts, in 2024.
Second Quarter 2023 Financial Results
As of June 30, 2023, TScan Therapeutics had cash and cash equivalents of $208.8 million, excluding $5.0 million of restricted cash. Based on current operating plans, the Company believes that existing cash and cash equivalents, along with proceeds from the collaboration with Amgen, will be sufficient to fund its operating expenses and capital expenditure requirements into 2026.
Revenue for the second quarter ended June 30, 2023, was $3.1 million, compared to $4.1 million for the second quarter ended June 30, 2022 (2022 Quarter). This decrease is primarily due to timing of research activities related to the collaboration agreement with Amgen in the second quarter of 2023 versus timing of research activities related to a collaboration and license agreement with Novartis Institutes for Biomedical Research, Inc. in the 2022 Quarter.
Research and development expenses for the second quarter ended June 30, 2023, were $21.2 million, compared to $14.5 million for the 2022 Quarter. The increase of $6.7 million was primarily driven by increased costs associated with clinical trial start-up fees and patient enrollment, increased personnel costs, and expansion of facilities.
General and administrative expenses for the second quarter ended June 30, 2023, were $6.5 million, compared to $4.8 million for the 2022 Quarter. The increase of $1.7 million in general and administrative expenses was primarily driven by increased legal fees related to transactions entered into during the second quarter of 2023.
For the second quarter ended June 30, 2023, TScan Therapeutics reported a net loss of $24.0 million, compared to a net loss of $15.1 million for the 2022 Quarter.
As of June 30, 2023, the Company had issued and outstanding shares of 47,818,766, which consists of 43,542,178 shares of voting common stock and 4,276,588 shares of non-voting common stock, and outstanding pre-funded warrants to purchase 47,010,526 shares of common stock at an exercise price of $0.0001 per share.
