2. An early-stage Amgen, specializing in live bacterial therapies.

3. CRISPR Therapeutics, but developing 'living medicines' from gut bacteria.

Synlogic (SYBX) is a clinical-stage biotechnology company focused on the research and development of a novel class of synthetic biotics for the treatment of rare metabolic and inflammatory diseases. As a company in the discovery and clinical development phase, Synlogic does not currently have "major customers" in the traditional sense of selling approved commercial products to either companies or individuals.

Companies at this stage primarily generate capital through equity financing, strategic collaborations, and grants, rather than product sales. If one were to consider entities that have provided significant funding or entered into strategic alliances (which are the closest equivalent to "customers" for a company at this stage of development), these would typically be larger pharmaceutical companies or government/non-profit organizations.

Historically, Synlogic has engaged in collaboration agreements that provided revenue. While specific major revenue-generating collaborations for their current pipeline are not active in a commercial product sales context, a notable past partner that fits the description of a company in a collaboration context was:

• Roche (Genentech): Synlogic had a research collaboration with Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY). This collaboration focused on inflammatory bowel disease and contributed to Synlogic's revenue during its active period, though it was terminated in 2021.

Currently, following a reverse merger, Synlogic's focus is on advancing its pipeline of investigational therapies for rare diseases, and it is not engaged in commercial product sales to other companies or individuals.

The clear emerging threat to Synlogic (SYBX) is the advancement and potential success of gene therapies for monogenic metabolic disorders, particularly Phenylketonuria (PKU).

Synlogic's lead product candidate, SYNB1934, is an engineered living bacterial therapeutic designed for the chronic management of PKU. Gene therapies, such as the investigational gene therapy by PTC Therapeutics for PKU, represent a fundamentally different and potentially curative approach. If gene therapies prove highly effective, safe, and durable, they could offer a one-time treatment for these disorders, significantly altering the standard of care and reducing the long-term market opportunity for chronic management therapies like Synlogic's. This potential shift from chronic treatment to a cure, driven by a rapidly advancing and distinct technological modality, represents a clear emerging threat to the market position of Synlogic's product candidates for monogenic disorders.

Expected Drivers of Future Revenue Growth for Synlogic (SYBX)

Over the next 2-3 years, Synlogic's future revenue growth is expected to be driven by the following key factors:

1. Clinical Development and Potential Commercialization of SYNB1353 for Homocystinuria (HCU): Synlogic's SYNB1353 program, aimed at treating homocystinuria, is a significant potential revenue driver. The candidate has received Fast Track and Rare Pediatric Disease Designations from the FDA, has demonstrated proof of mechanism in a Phase 1 study, and is advancing into a Phase 2 study. Successful progression through clinical trials and eventual market approval would position SYNB1353 as a primary source of product-based revenue.
2. Clinical Development and Potential Commercialization of SYNB8802 for Enteric Hyperoxaluria: Another key pipeline asset, SYNB8802, is currently in Phase 2 clinical trials for the treatment of enteric hyperoxaluria and has demonstrated proof of concept in a Phase 1b study. The successful advancement and potential commercialization of SYNB8802 represent an additional opportunity for future product revenue.
3. Expansion of and New Strategic Collaborations and Partnerships: Synlogic has an existing research collaboration with Roche for a novel Synthetic Biotic aimed at inflammatory bowel disease, which has generated milestone payments. Further expanding existing partnerships or forging new strategic collaborations for its Synthetic Biotic platform or other preclinical and clinical assets could provide significant non-product revenue through upfront payments, research and development funding, and potential future milestone payments and royalties.
