Insights
Analyzing Sangamo Therapeutics' recent business highlights and financial results, several key points emerge with potential implications for investors. The company's focus on developing genomic medicines for neurological diseases, particularly their proprietary AAV capsid technology (STAC-BBB), is noteworthy. This technology has shown promise in penetrating the blood-brain barrier, which is a significant hurdle in treating neurological conditions. The potential for this technology to advance into clinical trials with IND and CTA submissions planned for 2024 and 2025 could mark a substantial milestone in the company's pipeline progression.
The financial results indicate a net loss increase year-on-year, which is a concern for profitability outlooks. However, the rise in revenues in 2023 compared to the previous year suggests that the company's collaborative agreements, particularly with Biogen, are yielding financial benefits despite the termination of other collaborations. The company's cash position, which is expected to fund operations into the third quarter of 2024, signals a need for additional capital raising to sustain its research and development endeavors. The projected operating expenses for 2024, alongside the potential for non-dilutive funding through partnerships or additional capital raises, will be critical for Sangamo's financial sustainability and progression of its clinical programs.
From a medical research perspective, the preclinical data for Sangamo's STAC-BBB capsid technology represents a significant advancement in the field of gene therapy. The ability to deliver zinc finger payloads effectively across the blood-brain barrier could revolutionize the treatment of neurological diseases such as prion disease, tauopathies and chronic neuropathic pain. The reported 700-fold increase in transgene expression in neurons over the benchmark capsid AAV9 and the potent repression of target genes in non-human primates are particularly promising findings.
Moreover, the potential for Sangamo's technology to modify disease progression in prion diseases and various tauopathies could meet a high unmet medical need, as current therapeutic options are limited. The safety profile of the capsids in NHP studies, alongside their manufacturability at a commercial scale, is also encouraging for the transition to clinical trials. The FDA's alignment on an abbreviated pathway for the Fabry disease program and the EMA's PRIME eligibility indicate regulatory confidence in the potential of the company's gene therapies, which could expedite the approval process and bring these treatments to market sooner.
From a market perspective, the neurological disease treatment sector is rapidly evolving, with a growing emphasis on gene therapies that can overcome the blood-brain barrier. Sangamo's STAC-BBB technology positions the company at the forefront of this market segment. The anticipation of an IND submission for the chronic neuropathic pain program and a CTA for prion disease, along with the potential resumption of the tau program, could have significant market implications if successful.
The company's strategic decision to seek a partnership for the Fabry disease program reflects a trend in the biotech industry to leverage external expertise and resources to advance complex therapies. Sangamo's alignment with the FDA for a potentially abbreviated approval pathway for its Fabry disease treatment could be a game-changer, reducing the time and cost associated with bringing a new therapy to market. Furthermore, the potential milestone payments and royalties from the collaboration with Pfizer for hemophilia A treatment, if approved, represent a notable future revenue stream that could bolster the company's financial position and appeal to investors.
- Data from novel proprietary neurotropic adeno-associated virus (AAV) delivery capsid, STAC-BBB, demonstrated industry-leading blood-brain barrier (BBB) penetration in non-human primates (NHPs) following intravenous administration, with capsid-enabled delivery of zinc finger payloads targeting prion disease and tauopathies resulting in potent and widespread repression of target genes.
- Chronic neuropathic pain and prion disease preclinical programs advance, with investigational new drug (IND) and clinical trial authorization (CTA) submissions expected in the fourth quarters of 2024 and 2025, respectively.
-
Announced
U.S. Food and Drug Administration (FDA) alignment on an abbreviated pathway to potential approval, and grant by European Medicines Agency (EMA) of priority medicines (PRIME) eligibility for isaralgagene civaparvovec in Fabry disease. - Pfizer anticipates Biologics License Application (BLA) and marketing authorization application (MAA) submissions for Hemophilia A collaboration by early 2025 if the pivotal readout is supportive.
“In 2023, Sangamo announced the prioritization of its pipeline programs that support our focus as a neurology-focused genomic medicine company,” said Sandy Macrae, Chief Executive Officer of Sangamo. “With the meaningful preclinical data announced today, we believe our ability to combine potent zinc finger epigenetic regulation payloads with exciting new industry-leading capsid delivery technology could unlock significant potential for the treatment of devastating neurological diseases, indications for which delivery of treatments to the central nervous system has historically proved challenging. In the near-term, we are also seeking to create value by partnering our Fabry disease program, for which we aligned with the FDA on a potentially abbreviated and more cost-effective timeline and received EMA PRIME eligibility. We look forward to advancing our pipeline into the clinic to develop therapies designed to target neurological diseases with high unmet medical needs.”
Recent Business Highlights
Prioritized Neurology Pipeline
Sangamo is developing epigenetic regulation therapies to treat serious neurological diseases and novel proprietary AAV capsids designed to deliver our therapies to the intended neurological targets, including across the blood-brain barrier.
Novel AAV Capsid Delivery Technology – Data demonstrated industry-leading BBB penetration and brain transduction in NHPs, with capsid-enabled delivery of zinc finger payloads targeting prion disease and tauopathies resulting in potent and widespread repression of target genes.
- Novel STAC-BBB capsid demonstrated robust penetration of BBB with 700-fold higher transgene expression in neurons compared to the benchmark capsid AAV9 and outperformed all other known published capsid variants evaluated in the study.
- STAC-BBB mediated robust expression of zinc finger cargo in neurons, with potent and widespread repression of prion and tau genes observed across key brain regions, demonstrating the potential for modification of disease progression in prion disease and various tauopathies.
- Visualization of gene expression in individual brain cells by RNAscope revealed highly potent repression of tau in neurons expressing the zinc finger cargo, across multiple brain regions.
- Capsid biodistribution profile is optimal for the treatment of neurological diseases with AAV-based treatments, highlighted by the observed enrichment in the CNS and de-targeting from the liver, dorsal root ganglia (DRG) and other peripheral organs.
- STAC-BBB was well tolerated in NHPs, with no notable treatment related pathological findings in brain, spinal cord or peripheral tissues.
- We believe that STAC-BBB is manufacturable at commercial scale using standard cell culture and purification processes, is soluble using known excipients, and can be characterized using available analytics.
Chronic Neuropathic Pain – Preclinical data demonstrated potent and specific repression of Nav1.7 expression without impacting other sodium channels and that zinc finger repressors (ZFRs) were well tolerated in NHPs; IND submission expected in fourth quarter of 2024.
- IND-enabling toxicology studies are nearing completion.
- An IND submission is expected in the fourth quarter of 2024.
Prion Disease – Preclinical data demonstrated that AAV-delivered ZFRs significantly reduced expression of the prion protein in the brain, extended lifespan and limited formation of toxic prion aggregates in mice; CTA expected in the fourth quarter of 2025.
- CTA-enabling studies continue to advance.
- Prion-targeted zinc finger repressor, delivered via an intravenous administration of the STAC-BBB novel capsid, resulted in a dose-dependent repression of prion genes in NHPs.
- A CTA submission is expected in the fourth quarter of 2025.
Tauopathies – Preclinical data demonstrated that AAV-delivered ZFRs significantly reduced expression of tau mRNA in brain of NHPs; intend to resume development of this program, leveraging STAC-BBB; IND submission expected as early as the fourth quarter of 2025.
- Intend to resume development of our previously paused tau program, leveraging the newly identified STAC-BBB capsid variant, subject to additional funding.
- Tau clinical-lead zinc finger repressor, delivered via an intravenous administration of the STAC-BBB novel capsid, resulted in a dose-dependent repression of tau genes in NHPs. Visualization of gene expression in individual brain cells by RNAscope revealed highly potent repression of tau in neurons expressing the zinc finger cargo across multiple brain regions.
- We expect the IND submission could occur as early as the fourth quarter of 2025.
Other Programs
Fabry Disease – Dosed total of 32 patients in Phase 1/2 STAAR study, with updated clinical data presented at 20th Annual WORLDSymposium showing sustained benefit and differentiated safety profile; announced FDA alignment on abbreviated pathway to potential approval; actively seeking collaboration partner to advance asset toward potential registration and commercialization.
- Dosed seven additional patients in the dose expansion phase of the Phase 1/2 STAAR study evaluating isaralgagene civaparvovec, our wholly owned gene therapy product for the treatment of Fabry disease, for a total of 32 patients dosed to date.
-
Presented updated clinical data at the 20th Annual WORLDSymposium in
San Diego, CA in February 2024, showing that elevated levels of α-Gal A activity were sustained in all 24 patients evaluated as of the September 19, 2023 data cutoff date and accompanied by the reduction and/or long-term stabilization of lyso-Gb3 levels, with the largest reductions in plasma lyso-Gb3 seen in patients with the highest levels at baseline. - All 13 patients who were withdrawn from Enzyme Replacement Therapy (ERT) remain off ERT as of March 12, 2024.
- In the 13 patients followed for 12-months or more after treatment, renal function remained stable, and significant improvements in overall disease severity, quality of life, and gastrointestinal symptoms compared to baseline were reported.
- Aligned with the FDA that data from a single, adequate, and well-controlled study may form the primary basis of approval of a BLA for isaralgagene civaparvovec, enabling a potentially abbreviated and more cost-effective pathway to BLA submission than originally anticipated. The study would enroll up to 25 patients, both male and female, without the need for a control arm. A head-to-head comparison with ERT is not part of the proposed study design deemed acceptable by the FDA.
- Granted PRIME eligibility from the EMA for isaralgagene civaparvovec, which aims to enhance support for the development of medicines that target an unmet medical need and is intended to optimize development plans and expedite review and approval processes.
-
Granted Innovative Licensing and Access Pathway (ILAP) for isaralgagene civaparvovec from
U.K. Medicines and Healthcare products Regulatory Agency (MHRA) which aims to accelerate time to market and facilitate access to medicines. Isaralgagene civaparvovec has already received Orphan Medicinal Product designation from the EMA as well as Orphan Drug, Fast Track and Regenerative Medicine Advanced Therapy (RMAT) designations from the FDA. - Completed screening and enrollment in the Phase 1/2 STAAR study and expect to complete dosing of remaining patients in the first half of 2024.
- Deferring additional investments in planning for a potential registrational trial until a collaboration partnership or financing for this program is secured.
Hemophilia A (Pfizer) – Pivotal data read-out in Phase 3 AFFINE trial expected in mid-2024; BLA and MAA submissions anticipated by early 2025 if pivotal readout is supportive.
- A pivotal readout is expected in mid-2024 in the Phase 3 AFFINE trial of giroctocogene fitelparvovec, an investigational gene therapy we are developing with Pfizer for patients with moderately severe to severe hemophilia A.
- Pfizer anticipates BLA and MAA submissions by early 2025 if the pivotal readout is supportive.
- Presented updated data with Pfizer from the Phase 1/2 ALTA study of giroctocogene fitelparvovec in an oral presentation at the 65th American Society for Hematology Annual Meeting and Exposition in December 2023.
-
Eligible to earn from Pfizer up to
$220.0 million 14% -20% if giroctocogene fitelparvovec is approved and commercialized, subject to certain reductions.
CAR-Tregs – In alignment with previously announced strategic transformation, announced winddown of the Company’s French research and manufacturing operations and a corresponding reduction in workforce; continuing to seek a potential collaboration partner or external investment in the CAR-Treg cell therapy programs.
-
Announced a winddown of Sangamo’s French operations and a corresponding reduction in workforce, including closure of Sangamo’s cell therapy manufacturing facility and research labs in Valbonne,
France , which is expected to commence in April 2024 and be complete by end of year. We expect this restructuring to result in the elimination of all roles inFrance (approximately 93). - Dosed two additional patients in the Phase 1/2 STEADFAST study evaluating TX200, our wholly owned autologous CAR-Treg cell therapy treating patients receiving an HLA-A2 mismatched kidney from a living donor, including the first patient in the new fourth, highest dose cohort.
- Expect to dose up to two additional patients in the fourth highest-dose level cohort by the end of the second quarter of 2024.
- Plan to continue seeking a potential collaboration partner or external investment in our autologous CAR-Treg cell therapy programs.
