ST-920 appears well-positioned in Fabry disease, in our view.Today, we have established market model assumptions in Fabrydisease in which we estimate gene therapies (GTs) could generateglobal peak annual revenues in excess of $4.5B or more than $30B inaggregate from 2H24 to 2035. We believe ST-920, Sangamo's wholly-owned GT and among the most advanced AAV-based treatments indevelopment, could vie for market leadership. We reiterate our $25 pricetarget and Buy rating on SGMO shares, which we find very compellingat current levels.
Initial STAAR trial data expected by end of 2021. The STAAR studyrepresents the first in human treatment with ST-920, a recombinantAAV2/6 vector encoding the cDNA for human α-Gal A (αGLA). Asa reminder, in preclinical studies, ST-920 showed supraphysiologicalαGLA activity in several key tissues including the kidney, heart,spleen, and liver of mice, and reduced lyso-Gb3 below 10% of thatseen in untreated mice within two months post-treatment. In STAAR,Sangamo is to evaluate safety and tolerability of ascending doses ofST-920, which aims to provide stable, long-term production of αGLAat therapeutic levels in subjects with Fabry disease. The constantproduction of αGLA in humans should, importantly, enable reductionand potentially clearance of Fabry disease substrates Gb3 and lyso-Gb3. On Day 1, patients will be infused intravenously with a singledose of ST-920 and followed for a period of 52 weeks, per the protocol.Separately, we note that on May 3, AVROBIO, a biotechnology companydeveloping AVR-RD-01, an ex vivo lentiviral gene therapy for Fabrydisease, provided an adverse program update; specifically, AVROBIOcan no longer pursue an accelerated approval with a Phase 2 trial (FAB-GT) and instead intends to discuss with FDA a registration trial witha primary efficacy endpoint of clearance of GL-3 (also referred to asGb3) inclusions in biopsied renal peritubular capillaries (PTCs) as thebasis for full approval. AVROBIO noted that on March 11, approximatelythree weeks before a planned End-of-Phase 1 meeting, FDA grantedfull approval of Fabrazyme (agalsidase beta), an enzyme replacementtherapy (ERT), more than 18 years after it received accelerated approvalon the basis of a surrogate endpoint: reduction of GL-3/Gb3 inclusionsin biopsied renal PTCs. Sangamo has noted the following: (1) threepatients are enrolled and dosed in STAAR, with a fourth patient enrolledwhom should be dosed soon; (2) Sangamo is collecting biomarker dataas well as conducting kidney biopsies at the appropriate time; (3) theAVROBIO update is not germane to the STAAR program; Sangamois collecting the necessary data for a potential full approval of ST-920in Fabry disease, including Gb3 reduction in the kidney and long-termeGFR benefit; (4) Sangamo is collecting data in a range of patientsincluding those on ERT, those naive to ERT, and those pseudo-naiveto ERT, which should provide a broad dataset with which to discuss thepath forward for the program with the FDA, which we believe could occurin 2022 after data from STAAR is generated.
Model update. We fine-tuned our ST-920 estimates to better reflect ournew market model assumptions. Refer to pages 18-20 of this report foradditional details.
For definitions and the distribution of analyst ratings, analyst certifications, and other disclosures, please refer to pages 25 - 28 of this report.
Valuation and risks. We have assessed Sangamo using a discounted cash flow (DCF)-based and sum-of-the-parts (SOTP)-based valuation methodology. We assign probabilities of success to SB-525 in hemophilia A of 60%, to ST-920 in Fabry diseaseof 45%, to ST-400 in beta thalassemia of 30%, and to SAR445136 in sickle cell disease of 25%. We model a build in continuedmilestone payments tied to Sangamo's ZFP platform from 2021 and onward, and revenues tied to Sangamo's ZFP platform inthe late 2020s, leading to a moderate present value. We employ a 12% discount rate and a terminal multiple of 6.0x. Takentogether, these assumptions yield a total firm value of approximately $3.7B and price target of $25. Risks include, but arenot limited to: (1) clinical development risk tied to SB-525 and ST-920, among other programs; (2) commercialization risk; (3)reimbursement risk; (4) capital markets and dilution risk; (5) pricing risk; and (6) risk from COVID-19 should a renewed wavelead to a re-enactment of broad lock-downs globally.

Reiterate $25 Price Target and Buy Rating
• We value Sangamo using a DCF model based on net income per asset and free cash flow to the firm (FCFF), respectively.
The discount rate of 12% in the SOTP and DCF is comparable to clinical stage companies we cover. In our SOTP model, we
value each asset that we assign value to, including SB-525, ST-920, ST-400, and SAR445136, and Sangamo’s ZFP platform
value based on discounted net income, which includes an allocation of operating expenses and taxes to each asset.
• In our DCF, we start with GAAP net income and then add back selected non-cash items to arrive at FCFF for 2021 to 2035.
We think this timeframe extends long enough to capture the value from Sangamo’s pipeline and to reflect competitive
dynamics we anticipate over time. These cash flows are discounted back to approximately one year from now, as is the
present value of the terminal value, which is based on EBITDA in 2035 and a terminal multiple of 6.0x. This compares to the
long-term SMID biopharmaceutical average of approximately 10.5x and the 6.0x we are assuming for other
biopharmaceutical companies in our coverage.
• After adding back cash and securities of approximately $692M and subtracting debt of $38.4M we arrive at an implied equity
value of $3.7B. On diluted shares of approximately 149.1M, Sagnamo’s implied value is approximately $25/share or more
than 125% higher than the current share price.
• Hence, we reiterate our Buy rating on SGMO shares.

Brief Background on Selected Viral Gene Therapy Modalities
Source: Company filings, Bulcha, Wang, et al., H.C. Wainwright & Co.
Viral gene therapy modalities. In vivo gene therapy entails the direct administration
of vector carrying a therapeutic transgene into the patient. Ex vivo gene therapy
involves the extraction of a patient’s cells or from an allogenic source, genetic
modification by a vector carrying a therapeutic transgene, selection and expansion in
culture, and infusion to re-introduce the engineered cells back into the patient.
• Gene therapy (GT) is the treatment of a genetic disease by the introduction of
specific cell function-altering genetic material into a patient. The key step in
GT is efficient gene delivery to the target tissue/cells, which is carried out by
gene delivery vehicles called vectors.
• There are two types of vectors: viral and non-viral. Contemporary viral vector-
based gene therapy is achieved by in vivo delivery of the therapeutic gene into
the patient by vectors based on retroviruses, adenoviruses (Ads) or adeno-
associated viruses (AAVs). Alternatively, a therapeutic transgene can be
delivered ex vivo, whereby cells of a patient are extracted and cultured outside
of the body. Cells are then genetically modified by introduction of a therapeutic
transgene and are then re-introduced back into the patient.
• There are four basic gene therapy approaches as follows: gene replacement,
the delivery of a functional gene to replace a non-working gene; gene
silencing, inactivation of a mutated gene that has become toxic to cells; gene
addition, over expression of a “foreign” or exogenous gene to impact cellular
function; and gene editing, a permanent manipulation of a gene in a patient’s
genome.
• AAV vectors have been universally recognized as versatile vectors for gene
therapy. Much of this is owed to their wide-ranging tropism profiles, even by
the contemporary serotypes. As a result, most AAV vector platforms have
been developed to target diseases of the central nervous system, the eyes,
liver, heart, and muscle. The main consideration for AAV vector design is that
the wild-type genome is approximately 4.7 kb in size. Thus, vectors based on
them are irrevocably limited to an approximate 5 kb capacity. Additional
important aspects of vector design: (1) promoters or regulatory cassettes used
in AAV vectors, which drive transgene expression; and (2) capsids, which are
critical for recognition of cell surface proteins that impact tissue and cell
tropism, and also serve as the epitope for antibody recognition.
Summary of viral vectors used in clinical trials. (a) shows a pie chart with the
percentage of adenovirus, adeno-associated virus, or lentivirus vectors in use; (b)
shows a table including the current number of clinical trials employing the different
viral vectors.

Selected Vectors: Advantages, Disadvantages, and Future Directions
Source: Company filings, Nature, H.C. Wainwright & Co.
Vector Ad AAV Lentivirus
Advantages
• Delivery of many genome copies per target cell, that
typically translates into very high expression.
• Relatively large therapeutic genes (25-30 kb with the
latest generation vectors).
• Vector genomes are genetically stable.
• In vivo administration.
• Extensive clinical experience.
• Minimal issues with insertional mutagenesis.
• Several genome copies per target cell.
• Stable expression in some settings.
• In vivo administration.
• Generally safe at doses tested.
• Transduction rates of up to 90% of HSCs.
• High levels of transgene's expression.
• High titers (>108 TU/ml)
• Extensive clinical experience owing to HIV.
• High fidelity gene transfer due to intact integration
and absence of chromosomal rearrangements.
• Reduced genotoxicity vs. gammaretroviral vectors.
Challenges
• Since adenoviruses are non-integrating viruses, the
transgene expression typically lasts 1-2 months in non-
dividing cells, while is much shorter in dividing cells.
• High worldwide prevalence of pre-existing immunity
against common Ad serotypes including HAd5.
• Prevalence rates for NAbs against HAd5 range from
35% in the U.S. to more than 90% in Cote d'lvoire.
• Immunogenicity.
• Cellular toxicity.
• Small transgenes (approximately 4.7 kb)
• Transfer and expression are not always stable.
• Immunogenicity towards the vector remains the
largest challenge for AAV-based gene therapies.
• Managing the right treatment doses, which which
could be the cause of strong immunological responses
and subsequent toxicities seen in recent trials.
• Sensitive to chromosomal position effects.
• Limits on the size of the therapeutic gene (<10 kb)
insert.
• Potential problems with insertional mutagenesis due
to integration inside or near a proto-oncogene.
• Even self-inactivating lentiviral vectors with strong
promoter and enhancer elements can activate
neighboring genes.
• Integration can potentially form chimeric gene fusions
made up of proviral and host sequences.
• Lentiviral vectors have been shown to cause aberrant
splicing of cellular transcripts.
Future
Directions
• Several “rare” human serotypes with low
seroprevalence, such as HAd2, HAd26, and HAd35.
• Various non-human Ad vectors were developed to
limit cross-reactive immunity.
• High-capacity (HCAd) vectors can achieve long-term
transgene expression in vivo, since they have
dampened host immune responses against viral
proteins that may be residually expressed.
• Despite some setbacks, AAV vectors still hold
significant promise for correcting disease.
• Expect improvements to vector design to optimize
transgene expression while minimizing
immunogenicity.
• Continued efforts in guaging the long-term and short-
term safety for AAV vectors.
• Due to their ability to transduce non-dividing cells,
such as dendritic cells, recombinant lentiviral vectors
have been shown to elicit B cell- and T cell-mediated
immunity against infectious diseases and different
tumors.
• Recent advances in the development of non-
integrating lentiviral vectors have greatly reduced
insertional mutagenesis.
• Application of non-integrating lentiviral vectors to
circumvent immune responses mounted against
prolonged expression of genome editing tools, such as
CRISPR/Cas, facilitates the use of such systems in
therapeutic gene editing.

• Fabry disease is a rare, X-linked disease characterized by a congenital error of
glycosphingolipid metabolism caused by an abnormal gene encoding the α-Gal A
enzyme, which breaks down glycosphingolipids. Deficiency of αGLA results in the
accumulation of glycosphingolipids, such as Gb3, and its deacetylated form,
globotriaosylsphingosine, or Lyso-Gb3, that are associated with the
pathophysiology of the disease.
• There are several mutations underlying Fabry disease, which can be divided into
two categories: classic phenotype, the most severe form of the disease, which only
affects men without residual enzyme activity, and a generally milder nonclassic
phenotype also known as the atypical or late-onset form of the disease, which is
suffered by both men and women and is characterized by a more variable disease
course, in which patients are generally less severely affected and disease
manifestations may be limited to a single organ such as the kidneys or the heart.
• Fabry disease is associated with major disability, organ failure and premature
death, generally before the age of 60 years. Late-onset variants present later in life
with organ dysfunction which can be as severe as in the classic form of the
disease, but without the peripheral stigmata of pain, sweating abnormalities and
angiokeratoma. Fabry disease also affects heterozygote females with the defective
gene, where symptoms can develop about a decade later than males.
• Fabry disease is also a pan-ethnic disorder, meaning that it occurs in all racial and
ethnic populations affecting males and females. It is estimated that classic type
Fabry disease affects approximately one in 40,000 males. However, newborn
screening initiatives have suggested an even higher prevalence of the disease
(one in 3,100 male newborns found by a study conducted in Italy).

Fabry Disease: Additional Details

• Treatments and limitations: ERT. Currently no curative
therapies exist, and alternatives to enzyme replacement
treatment (ERT) for patients with Fabry disease are limited.
Fabry disease is primarily treated with periodic infusions of
ERT consisting of αGLA over the patient’s lifetime. The most
commonly prescribed ERTs for Fabry disease include
Sanofi’s Fabrazyme (agalsidase beta) and Takeda’s Replagal
(agalsidase alpha). ERT is beneficial for patients, reducing
Gb3 substrate levels and extending life expectancy for
patients, though requires chronic every other week infusions
over a life span and over time can lead to antibodies that limit
treatment effectiveness; 40% of male patients with classic
Fabry disease could develop anti-GLA antibodies. Moreover,
because of suboptimal pharmacokinetics and very short half-
life of a few hours, ERTs only temporarily increase plasma
enzyme levels and as a result patients continue to have
disease progression, including ongoing decline in renal
function, potentially resulting in renal failure, cardiovascular
disease and ongoing debilitating pain including periods of
severe pain crisis. ERT is also expensive, costing hundreds
of thousands of dollars annually.
• Treatments and limitations: Chaperone therapy. Amicus’
Galafold (migalastat) was approved by the EMA in May 2016
and FDA in September 2018. Galafold is a pharmacologic
chaperone that can bind to, stabilize, and enhance the
residual enzymatic activity of certain missense mutations.
Amicus reports that 35% to 50% of the gene mutations
associated with Fabry disease are amenable to migalastat,
implying a significant portion of the patient population is
ineligible.
Note: As shown above, therapies are directed at either replacing or generating deficient enzyme,
or blocking the accumulation of substrate. Clinical trials with gene therapy approaches to the
treatment of Fabry disease are ongoing. Chaperone therapy is now available for amenable
mutation with migalastat. Enzyme replacement therapy remains the mainstay of treatment for
most patients with Fabry disease, with agalsidase α and agalsidase β, while pegunigalsidase is
in clinical trials. Substrate reduction therapy (SRT) consists of glucosylceramide synthase
inhibitors and aims to reduce the accumulation of toxic substrate; SRT agents are currently in
clinical trials.

• ST-920. ST-920 is a recombinant adeno-
associated virus (rAAV) 2/6 vector encoding the
cDNA of human α-Gal A (AGA), which has a
sequence identical to the wild type enzyme. The
constant production of AGA in humans should
enable reduction and potentially clearance of
Fabry disease substrates Gb3 and lyso-Gb3 from
target organs. Importantly, we note that the same
rAAV capsid liver-targeted gene therapy has
been previously administered in patients with
hemophilia A (SB-525), demonstrating a positive
risk-benefit profile in data generated to-date.
• Compelling preclinical data. A detailed 3-
month pharmacology and toxicology study
showed that administration of a clinical-scale-
manufactured AAV2/6 vector resulted in
markedly increased plasma and tissue α-Gal A
activities, and essentially normalized Gb3 and
Lyso-Gb3 at key sites of pathology. Further
optimization of vector design identified the clinical
lead vector, ST-920, which produced several-fold
higher plasma and tissue α-Gal A activity levels
with a good safety profile.

STAAR design.
• Eligibility (screening up to eight weeks). STAAR includes men aged
18 years and older with diagnosis of classical Fabry disease. Patients
are to be enrolled from 10-15 clinics in the U.S. and UK. Patients can
continue on ERT during the trial.
• Key exclusion criteria. Known to be unresponsive to ERT;
neutralizing antibodies to AAV2/6; eGFR ≤ 60 ml/min/1.73m2;
contraindication to use of corticosteroids for immunosuppression; non-
classical Fabry disease.
• Primary endpoint. Incidence of treatment-emergent adverse events
(TEAEs) during 12 months after ST-920 infusion. Additional safety
evaluations are to include routine hematology, chemistry and liver
tests, vital signs, ECG and ECHO, serial alpha fetoprotein (AFP)
testing and liver MRI to monitor for any liver mass formation.
• Secondary endpoints. Change from baseline at specific time points
during the follow-up period: AGA activity in plasma; Gb3 and lyso-GB3
plasma levels; frequency of ERT; estimated glomerular filtration rate
(eGFR) calculated by creatinine levels in blood; and vector clearance
measured by level of vector genome in blood, saliva, urine, stool, and
semen.
• Exploratory endpoints. Left ventricular mass (measured by cardiac
MRI); quality of life; Fabry symptoms and neuropathic pain scores;
immune response to AAV and to AGA.
• Our view. Based on the data generated to-date we believe ST-920
could demonstrate the ability to normalize AGA activity in plasma in
adult males with classical Fabry disease.

Benchmarking the Competition: Freeline’s FLT190 Appears Promising

• FLT190. Freeline is developing FLT190 for treatment of Fabry disease. FLT190, based on the AAVS3 capsid, could provide sustained levels of functional
αGLA at a lower vector dose than other gene therapy programs for this indication, according to Freeline. To be sure, Freeline’s goal for FLT190 is to
bring αGLA activity in patients into the normal range with sustained steady state levels of between five to nine nmol/hr/ml, and potentially to a level that is
above the normal range, thus providing a treatment for Fabry disease that has the potential to be more efficacious, better tolerated and less burdensome
than ERT. We note that FLT190 builds on experience with FLT180a; both candidates utilize the same manufacturing process, and the capsid and
promoter are identical. As a result, we believe Freeline should be able to take learnings from the HB program, including predicted dose response and
immune management, into the Fabry program to potentially streamline and improve the clinical development program.
• Initial efficacy signal at lowest dose could imply next
doses in escalation phase enable patients to achieve
normal plasma GLA level. As of February 11, 2021, one
patient has been dosed with FLT190 in MARVEL-1. The first
patient was administered FLT190 at a dose of 7.5e11 vg/kg;
the infusion has been generally well-tolerated with no infusion-
related reaction, and no dose-limiting toxicity events (DLTs)
have been observed. Plasma GLA activity rose from a
baseline trough of 0.3 nmol/hr/ml to 1.2 nmol/hr/ml by week
four.
• Stable, elevated GLA expression after one year. The first
patient dosed continues to show stable elevated GLA
expression at 1 nmol/hr/cc at 12 months post treatment which
is approximately a 3-fold increase compared to their baseline
level. The subject restarted ERT from week six as the GLA
levels remained below the lower threshold of normal and
some peripheral nerve-related symptoms were reported.
Based on the dose response seen in B-AMAZE, a Phase 1/2
dose finding trial in hemophilia B evaluating FLT180a,
Freeline believes a dose of either 1.5e12 or 4.5e12 vg/kg has
the potential to bring patients into, or above, the normal range
of GLA expression.
FLT190 produced a 3-fold increase in plasma GLA, sustained over one year post-
treatment
Note: Data as of June 15, 2020; normal range for GLA in plasma is 5-9 nmol/hr/ml; below 1 nmol/hr/ml is
diagnostic for Fabry disease.

• AVROBIO. Lead candidate, AVR-RD-01, is derived from hematopoietic
stem cells to which the gene encoding plasma AGA is added in an ex vivo
process using a lentiviral vector.
• Positive data updates. In February 2021, AVROBIO reported that a kidney
biopsy taken at 12 months post-treatment from the fourth patient in the
Phase 2 trial (FAB-GT), who was the first in the trial dosed with AVROBIO’s
“plato” platform, showed a 100% reduction from baseline in the average
number of Gb3 inclusions per peritubular capillary (PTC). In addition, in
February 2021, AVROBIO reported data from the first four patients in the
FAB-GT trial measured as of 29, 24, 18 and 12 months, respectively,
indicating sustained increased leukocyte and plasma enzyme activity,
suggesting that these patients are now producing an endogenous supply of
AGA, as well as decreased plasma lyso-Gb3 levels in three of four patients.
These data followed a 2019 announcement that at 12 months post-
treatment the first patient in the FAB-GT clinical trial exhibited an 87%
reduction in the average number of Gb3 inclusions per PTC as compared to
baseline.
• Safety and tolerability. Preliminary interim safety data from Phase 1 and 2
trials indicate AVR-RD-01 has been generally well-tolerated with no SAEs
related to the study drug. Grade 3 or 4 AEs have generally been attributed
to the melphalan conditioning regimen prescribed by the study protocol.
• Adverse regulatory update. On May 3, AVRO announced it can no longer
pursue an accelerated approval with a Phase 2 trial (FAB-GT) and instead
intends to discuss with FDA a registration trial with a primary efficacy
endpoint of clearance of GL-3 (also referred to as Gb3) inclusions in
biopsied renal peritubular capillaries (PTCs) as the basis for full approval.
AVRO noted that on March 11, approximately three weeks before a planned
End-of-Phase 1 meeting, FDA granted full approval of Fabrazyme
(agalsidase beta), an enzyme replacement therapy (ERT), more than 18
years after it received accelerated approval on the basis of a surrogate
endpoint: reduction of GL-3/Gb3 inclusions in biopsied renal PTCs.

• Amicus. Amicus’ orally administered precision medicine monotherapy, Galafold, is designed to bind to and stabilize an endogenous αGA
enzyme in those patients with genetic variants identified as amenable in a GLP cell-based amenability assay. Amicus believes 35-50% of
Fabry disease patients may benefit from treatment with Galafold. Given the aforementioned advantages of GT treatment, to us, the
competition from Amicus vis a vis ST-920 comes more so from its GT candidate. In February 2021, Amicus presented initial preclinical
data from its investigational AAV gene therapy program, in development in collaboration with Penn. The initial preclinical study assessed a
range of single doses of AAV in Gla knockout mice with either wild-type hGLA (unmodified hGLA) or an Amicus/Penn engineered hGLA
transgenes (engineered hGLA or AT-GTX-701). The engineered hGLA AAV gene therapy demonstrated stable homodimer formation,
enhanced temperature, plasma and neutral ph stability compared to the unmodified hGLA AAV gene therapy. In the lowest tested dose of
AT-GTX-701, Gla knockout mice showed partial substrate reduction, while highest tested dose resulted in near complete substrate
reduction. Additionally, AT-GTX-701 demonstrated significantly greater lyso-Gb3/GL-3 substrate reduction across all Fabry disease
relevant tissues including the dorsal root ganglia (DRG), kidney, and heart, with reductions at low dose being equal to or greater than the
reductions observed at higher doses with wild-type transgene and provided the first evidence for DRG storage reduction in a Fabry mouse
model treated with an AAV gene therapy according to Amicus.
• uniQure. In September 2020, uniQure selected a lead gene therapy candidate (AMT-190) for the treatment of Fabry disease to advance
into IND-enabling studies. The lead candidate is a one-time administered AAV5 gene therapy incorporating the GLA transgene. In
preclinical studies comparing multiple product candidates, including constructs incorporating a modified alpha-N-acetylgalactosaminidase
transgene (modNAGA), AMT-190 demonstrated the most robust and sustained increases in GLA activity according to uniQure.
• Our view. We anticipate a robust market for GTs to emerge in Fabry over the next 10 years and believe ST-920 should vie for a leading
share of the market based on the preclinical data generated to date and the positive read through to the platform based on compelling
data generated to date on Sangamo’s most advanced compound, SB-525, partnered with Pfizer and in Phase 3 development (AFFINE).

Economic Case for GT in Fabry Disease Appears Clear to Us
Consensus estimates suggest ERT and chaperone
treatments could increase from $1.8B globally in 2020 to
$2.7B in 2026, a 50% increase.
If we assume a Fabry patient could receive SOC for 50 years, at
branded pricing, the global cost is near $120B, all else being
equal. Even if we assume biosimilars and generics enter the
market at a 50% and 80% reduction in cost, respectively, the
potential lifetime cost could still be more than $50B for SOC.

Market Model Assumptions: GT in Fabry
Of the compounds in development we believe
FLT190 and ST-920 could end up being the most
competitive given the advantages of the AAV
approach (non-integrating), and the safety and
efficacy demonstrated to-date. AAV and AMT-190
are behind the other programs, which is why we
model a lower share, at this time.
The market for GT is still wide open in Fabry, in
our view. For now, we are assuming parity pricing
among the many potential competing GT
treatments, if approved, at $3M per treatment,
before payments of discounts and rebates to
payors.
