Sangamo Therapeutics - Chapter 11 Case Summary

Sangamo Therapeutics has filed for Chapter 11 bankruptcy following the termination of its principal collaboration revenue streams from Biogen, Novartis, Kite, and Pfizer and more than $478 million in aggregate net losses over fiscal years 2023 through 2025, pursuing a dual-track Section 363 sale of its neurological technology platform assets to Eli Lilly at a $50 million stalking horse bid plus assumed liabilities, and its Fabry disease gene therapy program to Astellas Gene Therapies for $25 million at closing plus up to $25 million in milestones, backed by a DIP facility of up to $30 million from Northridge ATM.

Business Description

Headquartered in Richmond, California, Sangamo Therapeutics, Inc. ("Sangamo," the "Company," or the "Debtor") is a genomic medicine company focused on translating science into medicines for patients afflicted with serious neurological diseases. Genomic medicine refers to therapies that treat disease by directly targeting the genes that cause or drive it, rather than addressing its symptoms alone.

In 2023, Sangamo announced a strategic transformation into a neurology-focused genomic medicine company centered on two complementary areas:

These efforts are built on three proprietary technology platforms — the zinc finger protein ("ZFP") platform, the SIFTER AAV capsid engineering platform, and the Modular Integrase ("MINT") genome editing platform — which together form the scientific and technological foundation of the business. Sangamo applies these platforms across a pipeline of wholly owned, partnered, and other programs targeting serious diseases with limited or no adequate treatment options.

Sangamo's Chapter 11 case is anchored by two parallel sale processes, each supported by a stalking horse bidder:

Certain assets fall outside both transactions, including the Chronic Neuropathic Pain Program, the Hemophilia A Program, the Sickle Cell Disease Program, and the Tregs Platform. The Debtor intends to evaluate all available options for these assets through a postpetition marketing and sale process, under which it is also seeking authority to designate one or more additional stalking horse bidders.


Corporate History

Sangamo was incorporated in the State of Delaware in June 1995 and completed its initial public offering of common stock on the Nasdaq National Market on April 6, 2000.

The Company maintains three wholly owned subsidiaries, none of which are part of the Chapter 11 proceedings:

In 2023, Sangamo repositioned itself as a neurology-focused genomic medicine company, narrowing its strategic focus to epigenetic regulation therapies and engineered AAV capsid delivery. Against a backdrop of liquidity pressure, the Company undertook a series of restructuring actions that progressively reduced its operating footprint and headcount — including the closure of its Valbonne, France facility and efforts to exit its Brisbane, California facility — culminating in the Chapter 11 filing and the proposed Lilly and Astellas sales.


Operations Overview

Sangamo's operations center on three proprietary technology platforms that collectively form the scientific and technological foundation of its business and support a pipeline of clinical- and preclinical-stage programs.

Core Technology Platforms

Pipeline Programs

Sangamo's pipeline spans wholly owned programs, programs advanced with licensing and collaboration partners, and other programs being positioned for commercialization.

Wholly owned programs include:

Partnered programs are advanced under licensing and collaboration arrangements (the "Outlicensing Agreements"), which collectively represent potential recurring licensing revenue, milestone payments, and royalties on commercial sales:

Other programs, for which the Company is pursuing commercialization opportunities, include:

Intellectual Property

Sangamo protects its proprietary rights through a combination of patents, copyrights, trademarks, proprietary know-how, trade secrets, and confidentiality, materials transfer, research, and licensing agreements. Its portfolio comprises approximately 90 patent families directed to the design, composition, and use of zinc finger proteins and other technologies underlying its programs.

Manufacturing

Sangamo relies primarily on contract manufacturing organizations ("CMOs") to produce preclinical and clinical supply for its pipeline, and intends to continue using third parties for later-stage clinical trials and commercial-scale manufacturing of any approved product. The Company maintains a technical operations staff across process and analytical development, quality control, quality assurance, supply chain, project management, and external manufacturing to oversee its CMOs, support regulatory filings, and supply clinical trials.

Real Property

As of the Petition Date, the Debtor was party to three real property leases, all located in California:

Employees and Workforce Reductions

Sangamo has implemented a series of significant workforce reductions in recent years as it worked to lower operating expenses and preserve liquidity:

Following the June RIF, the Debtor's remaining workforce consists solely of employees specifically identified and selected by Lilly and Astellas in connection with their respective sales, together with those employees and independent contractors needed to assist with administration of the Chapter 11 case.


Prepetition Obligations

As of the Petition Date, the Debtor has no funded debt obligations—including no prepetition secured debt, unsecured notes, or credit facility obligations. The Debtor’s prepetition liabilities consist principally of general unsecured trade, lease, and employee-related claims, summarized below.
