(Nasdaq: ACET), a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for cancer, today reported financial results and operational highlights for the fourth quarter and year ended December 31, 2022.

“In 2022, Adicet demonstrated strong execution in advancing our gamma delta T cell therapy pipeline and clinical proof of concept for our therapeutic approach that may provide significant benefit for people living with cancer. Following the Phase 1 clinical update in December evaluating ADI-001 for relapsed or refractory non-Hodgkin’s lymphoma, we are continuing to track and enroll patients in the study and expect to report additional efficacy, durability, and safety data in the second quarter of 2023. We plan to discuss the design of our first potential pivotal study with the FDA in the second quarter of this year and initiate the pivotal portion of the study in the second half of the year, potentially in the third quarter,” said Chen Schor, President and Chief Executive Officer of Adicet Bio. “In addition, we plan to build on the preclinical data presented at ISCT, SITC and our R&D event, to expand our pipeline of first-in-class allogeneic, off-the-shelf gamma delta CAR T-cell product candidates, and in the second half of 2023, expect to submit an IND for ADI-925, our novel CAd gamma delta T cell product candidate.”

Fourth Quarter 2022 and Recent Operational Highlights:

• Announced Safety & Efficacy Data from Ongoing Phase 1 Study of ADI-001. In December 2022, Adicet reported interim safety and efficacy data from its ongoing Phase 1 study of ADI-001, Adicet’s investigational therapy targeting CD20 for the potential treatment of relapsed or refractory B-cell NHL. As of a December 5, 2022 data-cut date, treatment with ADI-001 demonstrated a 75% overall response rate (ORR) and a 69% complete response (CR) across all dose levels with a favorable safety and tolerability profile. Additionally, in 5/5 large B-cell lymphoma (LBCL) patients that previously relapsed after prior autologous anti CD-19 CAR T-cell therapy, treatment with ADI-001 demonstrated a 100% ORR and CR rate. Enrollment in the trial is currently ongoing to provide additional durability data and further support the recommended Phase 2 dose. In the second quarter of 2023, Adicet plans to discuss the design of its first potential pivotal clinical study evaluating ADI-001 in post CAR T LBCL patients with the U.S. Food and Drug Administration (FDA), and initiate the study in the second half of the year, potentially in the third quarter.

• Presented Preclinical Data for Four New Pipeline Programs at SITC Annual Meeting. In November 2022 at SITC, Adicet presented four posters highlighting preclinical data for four differentiated CAR and CAd gamma delta T cell programs targeting several hematologic and solid malignancies.

• Hosted R&D Pipeline Event Highlighting Preclinical Candidates. In November 2022, Adicet hosted an R&D event to provide additional detail regarding its emerging pipeline of allogeneic CAR and CAd gamma delta T cell therapy product candidates for a variety of cancer indications, including solid tumors. Adicet expects to submit an Investigational New Drug Application (IND) to the FDA for its lead preclinical candidate, ADI-925, in the second half of 2023.

• Appointed Nancy Boman, M.D., Ph.D., as Senior Vice President and Chief Regulatory Officer of Adicet. In November 2022, Adicet announced the appointment of Dr. Nancy Boman, M.D., Ph.D., as Senior Vice President and Chief Regulatory Officer. Dr. Boman brings nearly 30 years of industry experience in the biotech and pharmaceutical industry with expertise in regulatory, clinical development, chemistry, manufacturing and quality, leading more than 15 drug marketing applications.

• In-House Manufacturing Capacity Established in Redwood City Facility. In the fourth quarter of 2022, Adicet’s new in-house manufacturing capabilities in its Redwood City facility became operational. The facility is designed to enable drug product and vector manufacturing operations for early clinical development of Adicet’s pipeline candidates.

Financial Results for Fourth Quarter and Full Year 2022:

Three months Ended December 31, 2022

• Research and Development (R&D) Expenses: R&D expenses were $25.0 million for the three months ended December 31, 2022, compared to $14.7 million during the same period in 2021. The $10.3 million increase is primarily driven by a $3.4 million increase in payroll and personnel expenses, a net increase of $2.8 million for expenses related to contract manufacturing drug organizations (CDMO), contract research organizations (CRO) and consultant costs related to our lead product candidate ADI-001, and a $2.7 million increase in facility allocation.

The $0.2 million increase is primarily driven by an increase of $0.5 million of professional fees as well as a $0.2 million increase of payroll and personnel expenses. This increase was partially offset by a decrease of $0.1 million in recruiting fees. Payroll and personnel expenses for the three months ended December 31, 2022, includes $2.4 million of non-cash stock-based compensation expense compared to $2.7 million during the same period in 2021.

These increases were primarily due to increased headcount for the period. These increases were partially offset by a net $1.2 million decrease in facilities and other related expense.

The Company expects that current cash and cash equivalents securities as of December 31, 2022 will be sufficient to fund its operating expenses into the first half of 2025.
