Third Quarter & Recent Business Updates:

• ADI-001 Phase 1 Clinical Trial Enrolling in Dose Level 2. The dose-escalation portion of the Phase 1 study of ADI-001 for patients with B Cell Malignancies relapsed or refractory after at least two prior regimens has completed dosing in Dose Level 1. Enrollment is ongoing for Dose Level 2. The Company expects to report interim clinical data from the initial dose-escalation portion of the study by the end of 2021.

Neelapu, MD from UT MD Anderson Cancer center will present a Trials in Progress Poster for ADI-001 at the 63rd American Society of Hematology (ASH) Annual Meeting and Exposition on December 12 from 6:00pm to 8:00pm ET.

In September, Adicet announced that it entered into a collaboration with Twist Bioscience Corporation (Twist) to accelerate the discovery of gamma delta T cell therapies against five undisclosed targets.

Financial Results for Third Quarter 2021:

• Research and Development (R&D) Expenses: R&D expenses were $11.9 million for the three months ended September 30, 2021, compared to $8.9 million during the same period in 2020. The $3.0 million increase is primarily driven by an increase of $1.3 million incurred for contract research organizations, and consultant costs related to ramping up of clinical development activities related to our first product candidate, ADI-001 and other externally sponsored research expenses, an increase of $1.4 million in facility and other expenses and an increase of $0.4 million of contract manufacturing organization costs. These increases were partially offset by decreases in lab materials and supplies of $0.1 million and payroll and personnel expenses of $0.1 million. Payroll and personnel expenses for the three months ended September 30, 2021, includes $0.8 million of non-cash stock-based compensation expense compared to $1.0 million during the same period in 2020.

The $2.5 million decrease is primarily driven by a decrease in professional fees of $1.7 million, which includes a $1.9 million decrease related to legal and audit fees incurred due to our reverse merger in 2020 offset by $0.2 million increase in other administrative costs. In addition, there was also a decrease of $0.8 million related to payroll and personnel expenses, primarily related to consultant fees of $0.7 million. Payroll and personnel expenses for the three months ended September 30, 2021, includes $1.7 million of non-cash stock-based compensation expense compared to $2.0 million during the same period in 2020.
