Sarepta Therapeutics, Inc. (NASDAQ:SRPT) is a smart speculative biotech play to seem into. The explanation why is as a result of I consider further upside is imaginable at the premise that it might be able to download speeded up popularity of its gene remedy SRP-9001, which is being evolved for the remedy of sufferers with Duchenne muscular dystrophy (DMD).

The item is this corporate is already producing income the usage of its different FDA licensed medicine for DMD referred to as eteplirsen, golodirsen and casimersen. Alternatively, it holds attainable to put up its BLA to the FDA for SRP-9001 for DMD q4. If all is going neatly with the evaluate thereafter, then it is reasonably imaginable that it would download speeded up approval by means of mid-2023. There is not any ensure of this, however nonetheless stays a just right chance.

Regardless, internet product revenues in probably the most just lately reported quarter for the already licensed RNA-based PMO medicine used to be $211.2 million. This determine is necessary as it represents a expansion of internet product revenues by means of 50% in comparison to the second one quarter of the 12 months prior. If such expansion continues, then I feel the inventory will do neatly regardless. Talking of which, Sarepta even raised full-year steering on account of the expansion it’s been seeing with admire to gross sales. But even so SRP-9001, the corporate just lately authorized MyoAAV from The Wide Institute. The purpose of doing so is the power to seize an AAV this is way more environment friendly at decrease doses, whilst most likely having awesome efficacy. In essence, Sarepta holds the prospective to broaden an progressed gene remedy, one that might probably be awesome in comparison to SRP-9001.

Excellent Remarks Thus A long way For SRP-9001 For Duchenne Muscular Dystrophy

Sarepta has finished neatly to procure FDA speeded up approval previously for its DMD drug eteplirsen. It has additionally been ready to procure a couple of regulatory approvals thereafter with golodirsen and casimersen. The worldwide marketplace alternative for Duchenne Muscular Dystrophy is anticipated to succeed in $4.11 billion by means of 2023. How can it most likely advance the DMD remedy area even additional? Neatly, it could possibly accomplish that with SRP-9001. This can be a gene remedy which Sarepta has been advancing in collaboration with its spouse Roche (OTCQX:RHHBY). Sarepta had gained an prematurely cost of $1.15 billion and holds attainable to earn $1.7 billion in regulatory and gross sales milestones. Plus, the power to earn the everyday royalties on internet gross sales of this gene remedy as neatly.

I feel that issues might be able to move neatly for traders for the development of SRP-9001. Why do I say that? That is as a result of Sarepta had already spoken to the FDA about with the ability to report an utility for attainable speeded up approval of this gene remedy product for the remedy of DMD sufferers. Unusually, it were given some lovely just right comments. Topic of reality, with the comments it gained from the FDA, it intends to put up a Biologics Licensing Utility (BLA) to the FDA q4. This may be one main catalyst for traders to stay up for, one by which I feel may just purpose the inventory to upward thrust.

A 2d catalyst can be if Sarepta in the long run receives FDA popularity of SRP-9001, that could be imaginable by means of mid-2023. I consider those two occasions are going to be large for the biotech, as such I view them as just right business alternatives. It used to be ready to get to the purpose of with the ability to report a BLA within the fall for SRP-9001, on account of a couple of a success research. For example, in one of the crucial research, which is referred to as SRP-9001-103 (ENDEAVOR learn about). It used to be proven that sufferers who gained this gene remedy outshined those that gained exterior regulate. This used to be confirmed each in unadjusted method and least squared method in 20 sufferers elderly 4 to 7 as follows:

  • The use of unadjusted method at 1-year NSAA ranking – 4 issues development for SRP-9001 in comparison to 0.2 issues for exterior regulate
  • The use of least squared method at 1-year NSAA ranking – 3.9 issues development for SRP-9001 in comparison to 0.2 issues for exterior regulate

What does this knowledge imply and why do I consider there’s a just right likelihood SRP-9001 might be licensed? In essence, the purpose enhancements contain one thing referred to as North Famous person Ambulatory Evaluate (NSAA) ranking. This is a scale that determines if an individual can serve as independently on their very own in relation to muscle motion. The ratings are as follows:

  • 2 issues – customary process
  • 1 level – Changed approach however can nonetheless succeed in function impartial of bodily the help of someone else
  • 0 level – Not able to succeed in independently

The utmost ranking is 34 issues. Taking one instance from above with admire to NSAA, let’s take a look at the Unadjusted method at 1-year ranking. Once more, there used to be a 4 level development (development used to be 22.1 issues to 26.1 issues). This won’t appear to be a lot, however such an development is lovely large whilst you examine what the exterior regulate achieved. For individuals who took exterior regulate they went from 21.9 issues to 22.1 issues (0.2 level build up). As well as, the corporate launched pooled long-term effects from learn about SRP-9001-101. After 4 years of remedy, 4 sufferers accomplished a favorable imply 7.0 level distinction on overall NSAA ranking in comparison to baseline. When having a look at it in comparison to a propensity-weighted exterior regulate, overall NSAA ratings for the ones given the gene remedy remedy have been 9.9 issues (unadjusted method) and 9.4 issues (least sq. method).

The purpose here’s that remedy with gene remedy helped sufferers see a really perfect development in NSAA over an extended time frame. I consider there’s a just right likelihood that SRP-9001 would possibly obtain FDA speeded up popularity of SRP-9001 for the remedy of sufferers with DMD.

Possible Growth Of AAV Gene Supply With Capsid Enhancement

Whilst it’s up within the air whether or not or now not SRP-9001 might be licensed for sufferers with DMD, that does not imply Sarepta is not advancing different medicine for the exact same indication. Topic of reality, it evolved a license settlement with the Wide Institute (Wide Institute of MIT and Harvard) for using MyoAAV for Duchenne Muscular Dystrophy (DMD) and different positive sorts of neuromuscular and cardiac indications.

Straight away, you’ll be able to see that now not simplest can the corporate probably succeed in an enhancement for AAV gene remedy supply, however it additionally positive aspects an expanded pipeline against different indications. Why do I consider that this license settlement is a worth including match? This is because it relates to the likelihood that MyoAAV can’t simplest be way more efficient in comparison to SRP-9001, however is also more secure. All of it has to do with MyoAAV the usage of a changed outer protein shell of AAV (referred to as the capsid). The use of this, it is in a position to some distance outpace different adeno-associated viruses ((AAVs)). This used to be confirmed in knowledge printed in a clinical magazine referred to as Mobile in 2021, by which used to be proven that MyoAAV used to be ready to determine extra environment friendly of genetic payloads and supply of gene remedy. This resulted in muscle serve as being restored utterly and progressed survival charges in mouse fashions.

Secondly, in preclinical knowledge in non-human privates, MyoAAV accomplished many purposes of superiority over herbal AAV serotypes. One development of this sort of AAV is that it delivers 25-50 occasions larger gene expression in skeletal muscle tissue and 10-15 occasions larger gene expression in cardiac muscle. How can this lend a hand? Neatly, a lot decrease dosing achieves awesome efficacy. Protection enhancements famous are:

  • Decrease accumulation within the liver
  • 50% aid in decreased supply to the liver
  • MyoAAV can also be evolved for use as much as a log decrease dose in comparison to conventional AAV vectors (That is as a I described above in that efficacy is considerably higher extra in spite of a decrease dose being applied)

Even supposing this program is within the early phases, there’s hope that it would yield some distance awesome knowledge in comparison to SRP-9001. As well as, if it finally ends up understanding, then two probabilities may just come about. Some other partnership for MyoAAV with prematurely cost and milestones/royalties for starters. Secondly, talent to stay innovating to fend off any attainable pageant that can exist. Why the will for MyoAAV? That is as a result of present AAV choices are poisonous and don’t seem to be successfully delivered. Secondly, it may be delivered in doses as much as 250 occasions less than what is located for normal AAVs. It is all made imaginable due to the amendment of the capsid (outer shell of the AAV).

The tech used to be changed to be delivered way more successfully to muscle tissue. Alternatively, it might additionally most likely be finished with different organs as neatly. What is left now? It really works neatly in animal fashions and non-human primates. What must be finished now could be to peer the similar results in people. The one factor is that below the phrases of this license settlement is that Sarepta must pay an prematurely cost to the Wide Institute on most sensible of long term royalties and milestone bills.


In step with the 10-Q SEC Submitting, Sarepta Therapeutics had $1.9 billion in money, money equivalents, limited money and investments as of June 30, 2022. As I famous above, Sarepta Therapeutics already has 3 RNA-based PMO medicine licensed for the remedy of sufferers with DMD. It acquired internet product revenues of $211.2 million in Q2 of 2022, which used to be a 50% expansion over the similar quarter remaining 12 months. In line with the expansion it has noticed up to now, it has up to date its full-year steering for internet product income.

The brand new full-year steering vary for internet product income is now between $825 million and $840 million. It believes it has sufficient money to fund its operations for no less than June 30, 2023. Past that, it extremely is dependent what different methods it advances within the pipeline or could have to in the long run take away. If it does search money previous than anticipated, it’ll be because of a trade transaction or any other strategic cause now not but recognized.

Dangers To Industry

There are a number of chance elements that traders of Sarepta Therapeutics want to concern about. The largest chance of all of them can be whether or not or now not SRP-9001 might be licensed for the remedy of sufferers with DMD. Whilst I consider there’s a just right likelihood it’ll obtain FDA speeded up approval, there’s no ensure of this. As well as, if it’s not licensed by means of mid-2023, there might be two problems. The primary is that I be expecting the inventory to most likely drop by means of 20% or extra for starters. Secondly, relying upon the deficiencies famous, eventual regulatory approval would possibly take longer than anticipated.

A 2d chance can be because it pertains to the just lately authorized MyoAAV. Whilst it has carried out neatly in preclinical fashions and non-human primates, there’s no assurance that this generation will carry out the similar when human checking out is began.

The general chance is in keeping with the financials. Whilst it neatly capitalized for now, that does not imply it may not benefit from a pointy upward thrust within the inventory worth. I consider the sort of upward thrust may just happen when it information the BLA for SRP-9001 within the fall of this 12 months. As well as, it is imaginable it would carry previous to succeed in a strategic transaction.


I consider that Sarepta Therapeutics is a smart speculative biotech play to seem into. That is as it already has 3 RNA-based PMO medicine that have already been licensed for the remedy of sufferers with DMD. As I famous sooner than, internet product revenues had been hiking, with the newest quarter appearing a 50% 12 months over 12 months build up to $211.2 million.

There are two catalysts for traders to stay up for, which I consider can be large for the corporate and its inventory. The primary is the real submitting of the BLA for SRP-9001 for the remedy of sufferers with DMD. The second one catalyst may well be the imaginable FDA speeded up approval of this gene remedy for this affected person inhabitants in mid-2023.

Finally, it’s not simply pinning its hopes on SRP-9001 by myself. It has already taken the step to license MyoAAV from The Wide Institute. The prospective to make use of as much as a log decrease dose and most likely succeed in awesome protection/efficacy may well be groundbreaking. This would not even simplest be for DMD both, since the license settlement accounts for extra goal indications as neatly. I see many positives for this corporate and such, those are the the explanation why I consider this can be a nice speculative biotech play to seem into.
