Senti Bio Announces Third Quarter 2023 Results and Pipeline Updates

– IND for SENTI-202, a potential first-in-class logic-gated treatment for cancer, on track for clearance in Q4 2023 –

– Established new strategic collaboration with Celest Therapeutics for clinical development of SENTI-301A to treat liver cancer in China –

– Cash and receivables from GeneFab transaction expected to fund operations into Q4 2024 –

SOUTH SAN FRANCISCO, Calif., November 13, 2023 — Senti Biosciences, Inc. (Nasdaq: SNTI) (“Senti Bio”), a biotechnology company developing next-generation cell and gene therapies using its proprietary Gene Circuit platform, today reported financial results for the third quarter of 2023.

“The third quarter was highly productive for Senti as we continued advancing SENTI-202 towards IND clearance and further developed our platform technology,” said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. “Earlier this year, we set out to partner SENTI-301A and are pleased to have established a collaboration with Celest Therapeutics that could provide a differentiated treatment option for patients with liver cancer in China. The progress we made on Senti’s wholly-owned and partnered programs, which were highlighted at the SITC annual meeting, reinforces the potential applications of Gene Circuits to battle cancer.”



Senti Bio remains on track for having the Investigational New Drug (IND) application for SENTI-202 cleared by the FDA in the fourth quarter of 2023.
The Company expects to initiate the Phase 1 clinical trial for SENTI-202 in early 2024, with a focus on relapsed/refractory acute myeloid leukemia (AML) patients in the United States and Australia.
SENTI-202 is a first-in-class logic gated off-the-shelf chimeric antigen receptor natural killer (CAR-NK) cell therapy program designed to potentially overcome AML disease heterogeneity by targeting leukemic stem cells while sparing healthy cells, a key limitation of current therapies.

SENTI-301A for HCC

Last week, Senti Bio announced it has entered a strategic collaboration agreement with Celest Therapeutics (Shanghai) Co. Ltd (“Celest”), a China-based biotechnology company, for the clinical development of SENTI-301A to treat solid tumors in China. The Company has previously highlighted the significant prevalence of HCC and market opportunities for HCC treatments in Asia.
Through this collaboration, Celest will lead clinical development, operations, and manufacturing for the advancement of SENTI-301A with technical support from Senti Bio. Celest plans to enroll patients initially through a pilot trial in mainland China and expects to enroll the first patient in the first half of 2024.
Under the terms of the collaboration, Senti Bio will be eligible to receive up to $156 million in certain milestone payments, in addition to potential tiered royalty payments. Other terms of the transaction were not disclosed.
SENTI-301A is a calibrated release (cr) IL-15 multi-armed off-the-shelf CAR-NK cell therapy designed for the treatment of GPC3 expressing tumors, including HCC, the most common type of primary liver cancer.


Senti Bio and Celadon Partners Establish GeneFab

In August, the Company announced the transaction with GeneFab, LLC (“GeneFab”), a newly formed, independent contract manufacturing and synthetic biology biofoundry focused on next-generation cell and gene therapies. GeneFab will continue to be actively engaged in the CMC and manufacturing components for the clinical manufacturing of Senti Bio’s Gene Circuit product candidates.
In connection with the transaction, Senti Bio will receive total consideration of $37.8 million before the end of 2025 from GeneFab. Approximately $18.9 million was payable at closing, which was netted against an $18.9 million advanced payment owed by Senti Bio to GeneFab for future manufacturing and research activities. The remaining $18.9 million will be paid to Senti Bio in installments in 2024 and 2025, subject to satisfaction of certain conditions.
As part of the transaction, Senti Bio subleased its current good manufacturing practice (cGMP) facility in Alameda, CA to GeneFab. Approximately 35% of Senti Bio’s employees transitioned from Senti Bio to GeneFab, which will support the clinical manufacturing of Senti Bio’s chimeric antigen receptor natural killer (CAR-NK) programs, including SENTI-202.
Senti Bio will be entitled to receive 10% of the realized gains arising and resulting from any cash or in-kind distributions from GeneFab in connection with a dividend or sale event under the economic share agreement. GeneFab was also granted an option to purchase up to $20 million of Senti Bio’s common stock at a price of $1.01867 per share.


Four Presentations Highlighted at SITC Annual Meeting

Last month, The Company announced four poster presentations at the Society for Immunotherapy of Cancer (SITC) Annual Meeting. Two posters highlighted new preclinical data with BlueRock Therapeutics, and two posters demonstrated the application of Senti Bio’s proprietary Gene Circuit platform.


As of September 30, 2023, Senti Bio held cash, cash equivalents and short-term investments of $39.4 million. Inclusive of the receivables from the GeneFab transaction upon satisfaction of certain conditions, the Company expects to fund operations into Q4 2024.
Research and development expenses were $9.1 million for the quarter ended September 30, 2023, compared to $6.5 million for the same period in 2022. The increase was primarily related to manufacturing costs to support development of Senti Bio’s wholly-owned programs.
General and administrative expenses were $9.4 million for the quarter ended September 30, 2023, compared to $10.0 million for the same period in 2022. The decrease was mainly attributed to a reduction in professional services costs.
Net loss was $14.9 million, or $0.34 per basic and diluted share, for the quarter ended September 30, 2023, which included a non-recurring $21.7 million gain from discontinued operations, as well as a non-recurring $25.7 million impairment for leasehold improvements, both related to the GeneFab transaction.
Going forward, the Company expects stabilization in operating expenses, with higher spending on clinical expenses, offset by reduced research and development expenses from the GeneFab transaction.


Senti Bio plans to participate in the following upcoming scientific/medical conference:
