Senti Biosciences, Inc. (SNTI) is an early clinical-stage biotechnology company at the forefront of developing innovative cell and gene therapies using its proprietary Gene Circuit platform. With a focus on addressing major challenges in cancer treatment, the company has made significant strides in advancing its pipeline of next-generation therapies that aim to outsmart complex diseases.

Business Overview and Detailed Company History Senti Bio was founded in 2016 by a team of experienced scientists and entrepreneurs, with the goal of harnessing the power of synthetic biology to create more effective and targeted treatments. The company’s origins trace back to the pioneering work of its co-founders, who were inspired by the potential of gene circuits to reprogram cellular behavior and enhance the efficacy of cell-based therapies.

In the early years, Senti Bio dedicated its efforts to building a robust platform technology, conducting extensive research, and developing a pipeline of product candidates. The company’s Gene Circuit platform, which combines novel DNA sequences to create genetic programs that can sense inputs, compute decisions, and respond accordingly, became the foundation for its innovative approach to cell and gene therapy development.

As Senti Bio advanced its research, it attracted the attention of industry leaders and secured key partnerships. In 2021, the company entered into a collaboration agreement with Spark Therapeutics, a subsidiary of Roche, to leverage Senti Bio’s platform for the development of specific gene therapies. This partnership, valued at over $1 billion in potential milestone payments and royalties, further validated the company’s technology and its potential to transform the field of gene therapy.

In June 2022, Senti Bio completed a business combination with Dynamics Special Purpose Corp., a special purpose acquisition company (SPAC), and began trading on the Nasdaq Capital Market under the ticker symbol SNTI. This transformative event provided the company with additional capital to accelerate its clinical development efforts and expand its pipeline of next-generation cell and gene therapies.

Prior to the merger with Dynamics Special Purpose Corp., Senti Bio had successfully raised aggregate gross proceeds of $302.5 million through various funding sources, including share issuances, convertible notes, collaboration agreements, and government grants. This substantial funding allowed the company to organize and staff its operations, conduct comprehensive business planning, and carry out crucial preclinical studies.

In 2023, Senti Bio underwent a significant operational change by completing a transaction with GeneFab, LLC, a contract manufacturing and synthetic biology biofoundry. As part of this strategic move, Senti Bio divested its non-oncology business and in-house manufacturing services, while also subleasing its manufacturing facility to GeneFab. While this transaction provided Senti Bio with additional capital, it also necessitated adjustments to the company’s operations and workforce, reflecting the dynamic nature of the biotechnology industry and the company’s ability to adapt to changing circumstances.

Financial Snapshot As of September 30, 2024, Senti Bio reported a cash and cash equivalents balance of $10.5 million, which the company believes is not sufficient to fund its operations for the next 12 months. The company has incurred significant losses since its inception, with a net loss of $52.2 million and $52.3 million for the nine months ended September 30, 2024 and 2023, respectively. Senti Bio’s accumulated deficit as of September 30, 2024 stood at $296.5 million.

The company’s quarterly financial performance has been characterized by fluctuations in revenue, which amounted to $0 and $2.6 million for the three and nine months ended September 30, 2024, respectively, compared to $0.3 million and $2.0 million for the same periods in 2023. This decline in revenue is primarily due to the completion of the Spark Therapeutics collaboration in 2023.

Senti Bio’s research and development expenses have been a significant driver of its financial performance, accounting for $26.6 million and $23.0 million for the nine months ended September 30, 2024 and 2023, respectively. The company’s general and administrative expenses have also been substantial, totaling $18.0 million and $27.9 million for the same respective periods.

For the fiscal year 2023, Senti Bio reported revenue of $1.98 million, a net loss of $71.06 million, operating cash flow of -$52.40 million, and free cash flow of -$64.43 million. The most recent quarter (Q3 2024) saw revenue drop to $0, with a net loss of $28.87 million, operating cash flow of -$7.87 million, and free cash flow of -$7.87 million. The decrease in revenue compared to the prior year quarter was due to the completion of services provided under the Spark collaboration agreement in 2023. The decreases in net income, operating cash flow, and free cash flow were primarily due to continued investment in research and development for the company’s product candidates.

Liquidity The company’s financial condition and liquidity position remain a concern, as it continues to invest heavily in the development of its pipeline and the expansion of its platform technology. Senti Bio’s ability to achieve profitability and secure sustainable long-term funding will be crucial in determining its future success.

As of September 30, 2024, Senti Bio’s debt-to-equity ratio was 0, indicating no long-term debt on its balance sheet. The company’s current ratio and quick ratio were both 1.92, suggesting a reasonable short-term liquidity position. However, the company has concluded that substantial doubt exists about its ability to continue as a going concern for at least one year from the issuance date of its latest 10-Q filing, given its current cash position and expected future cash needs to fund its operations and product development activities.

Senti Bio maintains a $2.80 million letter of credit with JPMorgan Chase Bank related to the Alameda facility lease and a $0.50 million letter of credit with JPMorgan Chase Bank related to the headquarters facility lease, both of which are recorded as restricted cash.

Pipeline and Recent Developments Senti Bio’s pipeline is anchored by its lead product candidate, SENTI-202, a chimeric antigen receptor natural killer (CAR-NK) cell therapy targeting CD33, a clinically validated target for the treatment of acute myeloid leukemia (AML) and other hematological malignancies. In December 2023, the company received clearance from the U.S. Food and Drug Administration (FDA) for its Investigational New Drug (IND) application for SENTI-202, allowing it to initiate a Phase 1 clinical trial.

The Phase 1 trial for SENTI-202 commenced in the second quarter of 2024, with the company reporting the first patient dosed in May 2024. Senti Bio expects to provide initial clinical data from this trial by the end of 2024. The successful advancement of SENTI-202 through clinical development would be a significant milestone for the company, as it seeks to establish the potential of its Gene Circuit platform in the field of cancer immunotherapy.
