Excerpts & Highlights from the Report as conveyed by Argus Analyst Steve Silver, follow:
ProMIS Neurosciences, based in Toronto, Ontario, and Cambridge, Massachusetts, is a development-stage biotechnology company focused on the discovery and development of therapeutic antibodies selective for toxic oligomers that result from misfolded proteins. Such proteins are associated with the development and progression of neurodegenerative diseases including Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), and multiple system atrophy (MSA), among others.
The company's scientific platform features two proprietary target discovery engine algorithms that, collectively, can effectively predict the shape of Disease Specific Epitopes (DSEs) on the molecular surface of misfolded proteins that cause disease. Thus, its computational approach enables the development of selective antibody therapies against these targets. ProMIS' platform is based on the research of co-founder Dr. Neil Cashman, a scientist with over 25 years of experience in neurodegenerative diseases. Dr. Cashman, is a recognized leader in the field of protein misfolding diseases, including AD and ALS, and also serves as the ProMIS' chief scientific officer.
ProMIS' scientific thesis is that misfolded proteins, which expose toxic portions of the protein, are the primary culprit behind disease manifestation, and that efforts to inhibit all forms of the protein, including its abundant normal forms, are ineffective in treating diseases. Under such approaches, much of the administered dose is wasted by binding healthy protein or non-toxic aggregates before it reaches the relevant target in the brain. To date, the amyloid inhibition premise has been a primary focus of candidates for Alzheimer's disease, which has resulted in many failed, late-stage clinical studies. In contrast, ProMIS' platform selectively targets and inhibits only those mis-shaped epitopes exposed on the surface of misfolded proteins, and makes replicas of the misfolded regions, sparing the normal forms of proteins. ProMIS believes that immunizations with those epitopes result in more selective antibodies, which enable a lower effective dose that is expected to result in greater efficacy and a safer product profile. To date, ProMIS has achieved a
ProMIS' lead candidate is PMN310, a potential next generation therapy for Alzheimer's disease. It is designed to bind to toxic oligomers, which are misfolded aggregates of smaller units of a healthy protein called monomer. The program is currently undergoing IND enabling activities and is expected to begin a Phase 1b clinical study in AD patients in early 2023. In March 2022, ProMIS announced positive pre-clinical results in a mouse model of AD that showed that PMN310 prevented a cognitive deficit as measured by performance in the water maze task.
Importantly, the Phase 1b study will be an open-label, ascending dose design, and should provide monthly biomarker evidence of effect data that can confirm target engagement as well as safety. We expect the trial to be conducted in a modest five to eight centers, which should enable rapid enrollment.
To prepare for an IND filing to initiate these studies, ProMIS is currently developing its production cell line for antibody manufacturing and is preparing GLP toxicology and pharmacokinetics (PK) studies in nonhuman primates. ProMIS expects to complete the PK studies during the second quarter of 2022. Behind PMN310, ProMIS is advancing a pre-clinical pipeline of candidates for additional neurodegenerative diseases and dementias, including Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), which also share a common biologic cause – misfolded versions of proteins that perform a normal function, and that should not be inhibited broadly. As with PMN310, the platform selectively targets the toxic misfolded proteins with therapeutics and can detect them with diagnostics. In the case of ALS, antibodies are being designed that target misfolded forms of TDP-43, RACK1, SOD1, and ataxin2, with TDP-43 being the most advanced program.
For ALS, ProMIS is exploring different therapeutic modalities, including "intrabody", or inside the neuron, versions of TDP-43 antibodies that can be vectorized in a gene therapy vector, since physiologically important TDP-43 is active inside the neuron and should be avoided by the intrabodies in order to reduce the possibility of harmful side effects. In addition, ProMIS believes that addressing multiple misfolded protein targets could be beneficial to outcomes in ALS potentially with different modalities, including antibodies, vectorized intrabodies, and ASOs. To date, ProMIS has designated PMN267, focused on TDP-43, as its lead product candidate for treatment of ALS.
In our view, ProMIS' approach is validated and differentiated from other treatments and technologies in development due to its accuracy of computational modeling and artificial intelligence that enable the generation of therapeutic antibodies that are highly selective for toxic misfolded proteins and not their normal, physiological forms. The company has run robust simulations that have revealed conformational epitopes that are mostly likely to be exposed on misfolded proteins and provide strong predictability to support its antibody portfolio. Importantly, the company's platform can be applied across multiple degenerative diseases with a common protein misfolding pathogenesis, including Parkinson's Disease (PD), Multiple System Atrophy (MSA), in addition to its more advanced efforts in Alzheimer's and ALS.
ProMIS operates in an extremely attractive market that is among the largest areas of unmet needs across the entire biopharmaceutical industry. To date, neurodegenerative diseases have seen few novel drug approvals, and those approved have provided little more than symptom management or modestly slowed disease progression, rather than significantly impacting the underlying cause of the disease. In particular, Alzheimer's has been associated with multiple high profile failures, which have led to many Big Pharma leaders exiting the field. Before the June 2021 approval of Biogen's Aduhelm, the area had seen only one approval since 2003. However, despite its approval, Aduhelm has seen poor commercial adoption that we attribute to a trial design that failed to capture an unequivocal treatment benefit, which was compounded by its overpricing the drug in the market (it has been subsequently cut in half and seen its Medicare coverage limited) that has drawn considerable scrutiny and cast doubt on the entire field by regulators, insurers and, importantly, biotech investors.
That said, Aduhelm's approval sparked a boost to neurodegenerative disease focused IPO's and other financings for development-stage companies such as ProMIS. With a Phase 3 data readout by Eisai's lecanemab (BAN2401), which has a similar thesis to ProMIS, expected before the end of 2022, we think a positive readout would renew investor interest in the space, as well as enhance increased M&A interest from Big Pharma. We estimate that more than 100 candidates for Alzheimer's disease are currently in the clinic and view PMN310 as potentially representing a best-in-class opportunity.
We think that the ability to learn from earlier programs and approaches that have disproved prevailing thoughts on Alzheimer's has also positioned ProMIS to enhance its platform. Previous clinical programs have focused on amyloid monomer inhibition or targeting plaques in the brain containing amyloid, both of which have failed to yield an impact on disease manifestation, but have fostered a better understanding of the misfolded protein hypothesis. In addition, the advancement in biomarker detection and brain imaging in the pathology of AD has had a significant impact on ProMIS' design plans to use monthly biomarker analysis to determine more efficiently the effect of PMN310 when it begins clinical study. Further, we think that global regulators and specifically the US FDA have embraced the use of biomarkers to support evidence of effect, which we think could provide opportunities to rapidly conduct and advance the program. As such, we see ProMIS as well positioned to attract increased attention and interest from key stakeholders over the coming quarters.
In our view, ProMIS' antibody capabilities are well positioned to remain at the forefront of research in the neurodegenerative disease space, despite the emergence of several genetic technologies that are attracting interest across the biopharmaceutical industry. For example, we think ProMIS' approach is preferable to RNAi interference, as that technology could effectively address the genetic component of disease, but inhibit healthy amyloid in the process. Moreover, we do not view gene therapy as an ideal alternative for AD, given its permanence and potential to result in an unacceptable safety profile.
Another key differentiator for ProMIS is its access to some of the industry's distinguished leaders, both in its executive suite as well as in its scientific advisory board. As mentioned earlier, the executive team, led by Chief Scientific Officer Dr. Neil Cashman, possesses extensive clinical research experience as pioneers in the field of protein misfolding diseases. Its advisory board, which is chaired by Alzheimer's disease globally recognized thought leader Dr. Rudolph Tanzi, includes multidisciplinary specialists in neurodegenerative diseases, as well as experts in biotech business management, diagnostic product development, and monoclonal antibody design and manufacturing.
Lastly, we view favorably ProMIS' robust and growing IP portfolio, which included 47 patents and 67 applications, as of early 2022.
As we see it, ProMIS' progress in advancing its pipeline of candidates for neurodegenerative diseases into human clinical study is more material than its reported financials. During 2021, the company successfully completed several transactions that extended its cash runway and enabled the continuation of execution of its development strategy. Overall, we view its path to clinical value inflection favorably, given that its Phase 1b study will be open label and biomarker checked on a monthly basis, which should provide evidence of effect at a relatively early-stage. In addition, as mentioned earlier, we expect the appetite for M&A and financing for diseases such as Alzheimer's to improve over 2022, as new late-stage data is reported.
As of December 31, 2021, ProMIS had C
We view ProMIS' working capital position of C
Over the longer-term, we see its growing pipeline providing optionality for additional partnering activities. We think its product candidates as well as broad platform discovery capabilities are likely to attract the interest of a Big Pharma industry that is holding its highest level of cash and M&A capabilities in industry history. We expect Big Pharma to be monitoring the field closely before re-entering the market aggressively upon additional validation and maturity of some of these newer therapeutic options. We also think that ProMIS could fortify its balance sheet to keep many of its programs in-house into clinical study, so that it can garner enhanced deal economies, upon program validation.
