Duchenne Muscular Dystrophy The most common muscular dystrophy of childhood

1 in 3500-5500 boys BMD is about 1 in 18000-35000

X-linked recessive inheritance (Xp21.2) males affected & females carriers However, 1/3 cases are de novo mutation

Caused by mutation of dystrophin gene

Dystrophin gene is the largest gene in genome: 2.4 mb 14 kb mRNA coding sequence 3685 amino acid 427kDa protein 6

Page 7: CAP-1002 for Advanced DMD: A New Treatment Option

Duchenne Muscular Dystrophy Is a Devastating Progressive Disease with Significant Unmet Need

‣ Rare recessive x-linked disorder caused by mutation in the DMDgene

‣ Leads to dystrophin deficiency in muscle tissue and subsequently chronic activation of NF-kB

‣ Progressive disease that leads to devastating deteriorating muscle strength and early death

‣ Only supportive treatments are available– Physical therapy– Orthopedic Surgery for contractures and scoliosis– Assisted ventilation– Heart failure management (e.g., afterload reduction) – Off-label / labeled use of corticosteroids– Eteplirsen in the US for exon-51 mutations – Ataluren in the EU for nonsense mutations

Disease Progression Is Characterized by Muscle Damage and Replacement of Muscle Fibers with Fat Infiltration and Sclerosis, Resulting in Loss of Function

Normal muscle tissue Muscle tissue 19 year old DMD patient Post-Mortem

Fat infiltration, sclerotic changes and loss of muscle

fibers

Lack of dystrophin cause shearing of the sarcolemma and activation of NF-kB,

increasing cellular damage and muscle fiber loss

Progressive loss of muscle fibers and replacement of functional muscle units by

fat infiltration and sclerosis

Loss of function; walking capacity preserved in spite of significant loss of

muscle strength due to ‣ Reserve capacity in muscle function‣ Biomechanical compensations

Dystrophin Gene & Protein

• 8 different promoters• Differential tissue expression of dystrophin isoforms

• 79 exons (0.6% of gene) and most of the gene composed of non-coding introns

• Dystrophin protein organization:• N-terminal actin binding domain• 24 spectrin like repeats in the rod domain• Cysteine rich and c-terminal

• Dystrophin is an important component of DAG complex at muscle membrane• Muscle membrane stability• Cell signalling pathway

Duchenne dystrophy =Absence of dystrophinComplete loss of function

Becker dystrophy = Present, but abnormalPartial loss of function

Large in-frame deletionsCan be clinically very mild, asymptomatic BMD (hyperCKemia)

12

Page 13: CAP-1002 for Advanced DMD: A New Treatment Option

Types of mutations in Dystrophinopathies Deletions account for majority of mutations

~65-72% of DMD~85 % of BMDmost in “hotspot” region of exon 45-53

Point mutations and splicing region mutations~25-30%most result in nonsense/frameshift (stop); rare missense

Duplications~5-10%in minor “hotspot” region of exon 2-20

Premature stop codon mutation~13-15% 13

Page 14: CAP-1002 for Advanced DMD: A New Treatment Option

Reading Frame Rule

Out-of-frame mutations result in disruption of ORF→ premature stop codon→ truncated dystrophin/non-functional protein→ Absence of dystrophin→ DMD

In-frame mutations that preserve the ORF→ replacements of amino acids in dystrophin→ partially functional protein→ BMD

Majority of DMD and BMD follow this rule 14

Glucocorticoids target NF-κB which is Chronically Activated in DMD

• miRNAs in muscle microenvironments cause variable dystrophin in muscular dystrophy

• miRNAs are elevated in dystrophic myofibers and increase with disease severity

• Inflammatory cytokines induce miRNAs, and antiinflammatories block their expression

• miRNAs provide a precision medicine target in dystrophy and exon skipping

Steroid use and all-cause mortality in DMD

• Forty-five deaths occurred over almost 10 years of follow-up

• The odds ratio for death for those on GC treatment ≥ 1 year showed a reduced death risk by over 50%

• (odds ratio 0.47, 95% CI 0.22-1.00, p = 0.05).

Potential for Combination Treatments in DMD

‣ Six main categories for therapeutic targets for DMD

‣ One addresses primary genetic defect; rest address downstream aspects of the pathogenesis

‣ Targeting any single pathway may be an approvable mono-therapy

‣ Future treatment paradigm may involve targeting multiple pathways to have greater patient impact

Capricor’s Regulatory Designations - DMD

Rare Pediatric Disease Designation

Orphan Drug Designation

RMAT Designation

Goal: to facilitate efficient development and expedite review of a drug

Similar to breakthrough therapy designation: RMAT provides benefits that include more

frequent meetings with FDA to discuss the development plan for the product candidate

eligibility for rolling review and priority review Products may also be eligible for accelerated

approval on the basis of a surrogate or intermediate

endpoint reasonably likely to predict long-term clinical benefit

reliance upon data obtained from a meaningful number of sites

December 2018 RMAT Meeting Summary

71

Interdisciplinary meeting with FDA (CBER)

FDA suggested using PUL v2.0 as primary efficacy endpoint– Interim analysis was positive for PUL 2.0

FDA stated that the trial would need to show:– Evidence of clinically meaningful changes in the PUL– Stabilization or improvement in other measures of skeletal, respiratory

and/or cardiac function Interim analysis for HOPE-2 shows all of these improving in treated

patients over placebo

FDA advised CAPR to request an end of phase meeting after completion of the trial to determine whether HOPE-2 could serve as the registration study.

– Discussions with FDA are ongoing regarding CAP-1002 and DMD

‒ CAP-1002 is a biologic consisting of allogeneic cardiosphere-derived cells (CDCs)

Manufactured from donated heart muscle

Does not act by “stemness” – the cellsdo not engraft into host tissue

MOA: cells secrete exosomes: Contain miRNA, non-coding RNAs and proteins Internalized by target cells Stimulate diverse and lasting changes in cellular behavior 3 known miRNAs drive CAP-1002 potency

CAP-1002 has been investigated in multiple independent clinical trials and more than 150 human subjects

HOPE-2 Interim Analysis Safety Results

75

A total of 57 infusions were performed in HOPE-2 as of July 31, 2019 With the exception of two serious adverse events1,2 in the form of

immediate allergic reactions, no safety signals were identified To reduce the risk of future adverse events, Capricor initiated a

commonly used pre-medication regimen including oral steroids and antihistamines Since initiation of the pre-treatment regimen, approximately

40 infusions of CAP-1002 or placebo have been administered with only one serious adverse event1 reported that required an overnight observation of the patient.

Conclusions and Future DirectionsConclusions:

First placebo-controlled trial in DMD to use PUL 2.0 for evaluation of efficacy First placebo-controlled trial

showing upper limb functional improvements in non-ambulant DMD patients Directionally consistent

improvements in function, strength, pulmonary and cardiac endpoints

Moving Forward:

Meet with FDA to determine if CAP-1002 potentially qualifies for accelerated approval based on RMAT standards
