Precigen (NASDAQ:PGEN) is a biotech to regulate due to its part 1/2 research it’s advancing utilizing its lead immunotherapeutic vaccine referred to as PRGN-2012, which is getting used to deal with sufferers with recurrent respiratory papillomatosis [RRP] in an ongoing part 1/2 trial. That’s as a result of there was a number of optimistic developments because it pertains to this program. The primary and most vital development can be the optimistic discuss that it had with the FDA. That’s, the company is permitting the at the moment ongoing part 1/2 single-arm research may very well be used as a pivotal one, whereby an Accelerated Approval Submitting may very well be made. Given this growth, it’s within the technique of initiating a pivotal confirmatory research earlier than the submission of a Biologics Licensing Software [BLA] for this program. A BLA submitting of PRGN-2012 for the therapy of sufferers with RRP is anticipated to happen within the 2nd half of 2024.
Not solely that, however this federal company has additionally already given PRGN-2012 Orphan Drug Designation and Breakthrough Remedy Designation as effectively. ODD was additionally given from the EMA in Europe as effectively on January sixteenth of 2024. This program is in fine condition, as a result of full outcomes from the part 1 portion had been already printed in a peer-reviewed medical journal. The Part 2 portion of this part 1/2 research is anticipated to finish enrollment with 35 sufferers in Q2 of 2024, whereby a part 2 information presentation might be launched. PRGN-2012 makes use of the corporate’s AdenoVerse expertise, which has a number of benefits of being deployed as an immunotherapeutic vaccine over others.
PRGN-2012 Supplies Foundation For AdenoVerse Know-how Development
As I acknowledged above, PRGN-2012 is an immunotherapeutic vaccine, which makes use of the corporate’s off-the-shelf AdenoVerse expertise platform. This platform makes use of its gorilla adenovector expertise that helps it to focus on human papillomavirus [HPV] 6 or HPV 11 for the therapy of sufferers with recurrent respiratory papillomatosis [RRP]. RRP is a dysfunction whereby recurrent growths seem on the vocal cords or the tissues that encompass the vocal cords. This expertise, plus AdenoVerse is extremely ultimate in comparison with different therapeutic vaccine approaches. Why is that? That’s as a result of it could be secure sufficient for repeat administration with none undue toxicities. Secondly, it has the flexibility to ship a big genetic payload, which might presumably improve efficacy. Lastly, the shortcoming to duplicate in vivo means decreased danger of publicity to wholesome human cells. In addition to the truth that this modified remedy doesn’t trigger cytopathic or cytotoxic results in wholesome regular cells in a affected person’s physique. There is no such thing as a treatment for RRP and the present commonplace of care [SOC] just isn’t ultimate, as a result of it includes repeated endoscopic debulking with ablation or excision of the lesion itself.
That is the place the part 1/2 research comes into play, in that it’s utilizing PRGN-2012 as an adjuvant to be given to those sufferers with RRP. By adjuvant, I imply that this remedy goes to be given through subcutaneous injection earlier than commonplace of care [SOC] debulking surgical procedure. As I acknowledged above, the place I imagine worth will be unlocked right here is as a result of Precigen already had a extremely optimistic assembly with the FDA with respect to the info it had achieved up to now. Through the assembly it had, it was established that the continuing part 1/2 research might function a pivotal one. That is big for my part, as a result of which means upon completion of this trial, the corporate can be allowed to file a Biologics Licensing Software [BLA] to the FDA of PRGN-2012 for the therapy of sufferers with RRP. Matter of truth, it believes that it’s on observe to report part 2 information presentation in Q2 of 2024 after which a BLA submitting being completed by the 2nd half of 2024. I feel the reasoning for having such a productive assembly with the U.S. FDA is due to the info it was capable of acquire from this early-stage research. It was proven that sufferers given Dose Stage 2 of PRGN-2012 had helped 50% of sufferers obtain an entire response [CR]. This is superb, as a result of these are sufferers who would want recurrent surgical procedures. With this therapy, such sufferers didn’t require post-treatment surgical procedures to take away lesions. All this that was completed was completed so in a really secure method. That’s, no therapy associated opposed occasions [TAEs] > Grade 2 had been proven to be exhibited for the sufferers given this actual Dose Stage. One key query to ask is that if these sufferers didn’t want surgical procedure after therapy, how lengthy has their CR been ongoing? There’s excellent news on this entrance as effectively, as a result of with common follow-up vary of 18 to 24 months after PRGN-2012 therapy, it was famous that every one those that responded had been nonetheless surgical procedure free.
One other good side to contemplate right here can be the market alternative that’s attainable for RRP. The corporate believes that it might acquire $2 billion in peak annual gross sales globally for PRGN-2012 for RRP. Nevertheless, it gained’t come simple, as a result of one other biotech by the identify of Inovio Prescription drugs (INO) was given the flexibility to file a BLA after solely having accomplished a part 1/2 research. That’s, it expects to file its BLA of INO-3107 by the 2nd half of 2024 and request for Precedence Evaluation as effectively. Regardless, each corporations are going to be required to start out confirmatory research earlier than with the ability to submit a BLA. The excellent news is that they don’t should get such pivotal research accomplished to obtain Accelerated Approval for RRP. There’s an ongoing part 2 research by the NCI utilizing Avastin [bevacizumab] for the therapy of sufferers with RRP. Nevertheless, this research just isn’t anticipated to finish till November of 2025. One other research being completed is a part 2 one, whereby LENVIMA [Lenvatinib] is being mixed with Keytruda [pembrolizumab] for the therapy of sufferers with HPV-associated recurrent respiratory papillomatosis [RRP]. Issues bode effectively for Precigen’s PRGN-2012, as a result of it was simply granted Orphan Drug Designation from the European Fee. As well as, to the truth that this AdenoVerse therapy was given this standing together with Breakthrough Remedy Designation from the FDA.
Financials
In accordance with the 10-Q SEC Submitting, Precigen had money, money equivalents, short-term and long-term investments of $79 million as of September thirtieth 2023 It believes that it has sufficient money available to fund its operations into 2025. The explanation why it is ready to lengthen its money runway for this prolonged time frame is as a result of it has been capable of scale back its bills. Particularly Promoting, normal, and administrative [SG&A] prices have decreased by 9% and 17% for the three months and 9 months ending 2023, respectively. If it does want to boost money, then it can possible accomplish that in the direction of the top of 2024. Nevertheless, what’s encouraging is that administration not solely reprioritized its enterprise but it surely intends to hunt out different means to boost money. That’s as a result of the BLA, together with beginning to put together for commercialization of PRGN-2012, means it wants to start out discovering methods to boost vital capital. To perform this purpose, it needs to increase its runway even additional, which may very well be by way of growing a strategic partnership. A partnership being made with respect to PRGN-2012 or some other medical candidate within the pipeline might imply a technique to acquire non-dilutive capital.
Dangers To Enterprise
There are a number of dangers that buyers ought to concentrate on earlier than investing in Precigen. The primary danger to contemplate can be with respect to the attainable BLA submission of PRGN-2012 for the therapy of sufferers with RRP. Regardless that the corporate obtained steering that it might submit a BLA, there is no such thing as a assurance that the submitting might be accepted by the FDA. A second danger to then take into account can be upon the evaluation of the BLA submitting whether it is finally accepted by the company. There is no such thing as a assurance that will probably be given U.S. advertising approval for the therapy of this affected person inhabitants upon completion of this evaluation.
A 3rd danger to then take into account can be with respect to competitors. Even when Precigen receives regulatory approval of this remedy for RRP, it could should finally compete towards Inovio, with its therapy of INO-3107. The fourth and remaining danger to contemplate can be with respect the confirmatory research of PRGN-2012 for RRP. That’s as a result of if Accelerated Approval is given for it, that can solely be the start. To ensure that Precigen to maintain its drug in the marketplace, it wants to fulfill the first endpoint for a part 3 confirmatory research. Ought to this late-stage confirmatory trial fail, then there’s a good likelihood that the FDA might pull the drug off of the market.
Conclusion
Precigen has a shot at receiving Accelerated Approval from the FDA of PRGN-2012 for the therapy of sufferers with recurrent respiratory papillomatosis [RRP]. Nevertheless, it nonetheless has a variety of work that must be completed with the intention to obtain this finish purpose. First, it has to submit and the FDA has to just accept its regulatory software of PRGN-2012 for evaluation. Secondly, it should obtain U.S. advertising approval for it. I imagine there may be worth right here, as a result of peak international gross sales for focusing on this indication may very well be $2 billion globally. It has one other merchandise in its pipeline, which is PRGN-2009, which is an off-the-shelf AdenoVerse immunotherapy being developed to focus on HPV-associated optimistic stable tumors.
There was a part 1 research accomplished utilizing PRGN-2009 as a monotherapy or together for the therapy of sufferers with recurrent or metastatic HPV-associated cancers. Information from this explicit research was offered on the 2023 ASCO Annual Assembly. It was proven that when PRG-2009 was mixed with bifunctional fusion protein focusing on PD-L1 and TGF-beta [bintrafusp alfa] for the therapy of sufferers with recurrent/metastatic HPV-associated cancers, that there was a 30% goal response charge [ORR] noticed. Having stated that, the corporate is already exploring using PRG-2009 + KEYTRUDA for the therapy of sufferers with newly identified oropharyngeal squamous cell carcinoma [OPSCC] in a part 2 research, with plans to provoke one other one in 2024 to make use of PRGN-2009 + KEYTRUDA to deal with sufferers with recurrent or metastatic cervical most cancers.
