A team of researchers from the MIT Sloan School of Management, the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital (MGH), Questrom School of Business at Boston University, and QLS Advisors have introduced a new approach to funding clinical trials for amyotrophic lateral sclerosis (ALS) therapies. The study, “Financing Drug Development via Adaptive Platform Trials,” published today in PLOS One, outlines a financing model that merges the efficiencies of adaptive platform trials — lower costs and shorter durations — with an innovative, royalty-based investment structure designed to accelerate therapeutic development for ALS and other serious diseases.

ALS — also often called Lou Gehrig’s disease — is a progressive, neurodegenerative disease with no cure. Despite its devastating impact, the pace of new therapy development has remained sluggish—largely due to the high cost, duration, and risks associated with traditional clinical trials. This bottleneck has often discouraged conventional investors, leaving promising research to languish.

To tackle this challenge, the authors propose an investment fund that finances half the cost of an adaptive platform trial in exchange for future royalties from successful drugs that emerge from the trial. Adaptive platform trials allow multiple drug candidates to be tested simultaneously under a single master protocol, and results are interpreted on a real-time basis to determine efficacy or futility. Drawing on data from the HEALEY ALS Platform Trial administered by the Healey & AMG Center for ALS at MGH, and realistic assumptions, their simulated fund generated an expected return of 28%, with a 22% probability of total loss, which may be attractive to more risk-tolerant and impact-driven investors such as hedge funds, sovereign wealth funds, family offices, and philanthropists. Their findings suggest that generating returns more palatable for mainstream investors could be achieved by funding multiple platform trials simultaneously and by employing financial tools such as securitization — a method that bundles future income from assets like loans or royalties into investment products.

“ALS clinical trials face significant hurdles — from high costs and long timelines to limited funding pools,” said Merit E. Cudkowicz, MD, MSC, Executive Director at Mass General Brigham Neuroscience Institute and Director of the Healey & AMG Center for ALS. “Our platform trial model has already shown that we can test more therapies more efficiently. What’s still missing is sustainable financing. This novel approach could be a game-changer, enabling us to launch trials faster, include more promising therapies, and bring us closer to our shared goal: delivering effective treatments to people with ALS as quickly as possible.”

While their study focused on ALS, the authors believe such a funding model could be applied to other disease areas as well, especially those with well-defined endpoints, where treatment success can be measured clearly and reliably.

A New Wave of Academia Spinouts is Shaking up Drug Development

In recent times, new drug discoveries by independent large pharmaceutical companies have become increasingly rare, with almost 60% of new drugs discovered through mergers and acquisitions and drug licensing. Fortunately, an emerging trend of spinouts from academia and R&D investments heralds a promising shift in the industry’s interorganisational deal networks to improve research and development in the future. Researchers explore this new trend in Drug Discovery Today.

Launching a new drug in the market is risky, thanks to a low probability of success during the research and development (R&D) phase and the high costs involved. But through an improved understanding of disease biology, decision-making can be more streamlined through the effective use of scientific information.

With this in mind, researchers from Ritsumeikan University, Japan, led by Associate Professor Kota Kodama are uncovering how the trends in interorganisational deals in the pharmaceutical industry are changing to improve R&D productivity and drug discovery. “The network structure of innovation creation in the pharmaceutical industry has changed with the increasing emergence of start-up companies spinning out from academia and research institutions as players in the source of innovation,” explains Dr Kodama.

Their research suggests that the knowledge necessary for breakthrough innovation in drug discovery is more often than not obtained through alliance networks. Over the past decade, large research-based pharmaceutical companies have used research collaborations, innovation incubators, academic centres of excellence, public-private partnerships, mergers and acquisitions (M&As), drug licensing, and corporate venture capital funds as typical methods for external innovation. The researchers now aim to define the changes in the network structure and nature of such alliances that have occurred over the past decade to provide future strategic insights for industry and academic players involved in drug discovery.

Using data from the Cortellis Competitive Intelligence database, the researchers identified nearly 50 000 deals of various kinds related to pharmaceutical R&D across pharmaceutical, digital health software, animal drug, and medical device companies to uncover trends in the creation of new drugs for human use. They also studied the trends of 13 of the largest pharmaceutical companies with annual revenues of more than US$10 billion, who saw an improvement in their CAGR (compound annual growth rate) since 2015. The researchers noticed that the rising CAGR correlated to a significant change in M&A-related deals after 2015, indicating that M&A-related deals drive revenue growth for large pharmaceutical companies.

Furthermore, the number of organisations involved in interorganisational deals has been increasing yearly from 2012 to 2021. Although the number of organisations involved and the number of deals may be increasing, the density of the deal networks is decreasing annually, suggesting that networks are becoming more non-cohesive. The concentration of business relationships between organisations of certain areas in the network changed to dispersion around 2015, and new networks connecting different groups started to form after 2017. These trends are an important illustration of how the industry landscape is gradually evolving away from the traditional network in which large pharmaceutical companies drove drug discovery output. Now, interorganisational deals among more diverse players have become active and are driving R&D productivity for startups in biotechnology and pharmaceuticals.

A clear increase in the number of academia-owned spinouts of advanced technology and expansion of investment in start-ups is a positive sign. The emergence of new chemical modalities, such as biologics, oligonucleotides, and peptides that differ from traditional small molecule drug discovery indicate remarkable changes that have taken place over the past two decades. The trend of increased financing for start-up companies in personalised drug development is beneficial for patent creation and will positively impact innovation creation in the coming years.

“The presence of academia to support the technologies of these start-ups is becoming very important, and government and private support and investment in this area is boosting innovation. Our study shows that such medium- and long-term support may ultimately benefit the health and well-being of humankind,” concludes an optimistic Dr Kodama.

Discovery Offers New Treatment for Sickle Cell Anaemia

On By ModernMedia

In a promising step towards a new treatment for sickle cell anaemia, researchers have discovered a small molecule that boosts levels of foetal hemoglobin, a healthy form that adults normally do not make.

Current treatment options are few, including bone marrow transplants and gene therapy, and only address a subset of symptoms. Opioids are used for pain management, with their hazard for addiction and abuse.
The researchers presented their results at the spring meeting of the American Chemical Society (ACS).

“Using our proprietary small molecule probe and CRISPR guide RNA libraries, we screened a disease-relevant cell model that allowed us to pinpoint a treatment target,” said Ivan V Efremov, PhD, senior director, head of medicinal chemistry of Fulcrum Therapeutics.

Sickle cell disease occurs when genes for two of haemoglobin’s four proteins contains an error, resulting in a rigid, sickle-like shape. This has consequences in reduced oxygen transport, and painful blockages of the irregularly shaped cells called vaso-occlusive crises. The red blood cells die fast, leading to anaemia. These patients are also at high risk of developing stroke, heart disease, kidney failure and other potentially deadly conditions.

While in the womb, humans make “foetal” haemoglobin that carries oxygen normally but three or four months after birth, cells switch to an adult haemoglobin version. Although the adult haemoglobin expressed by sickle cell patients is defective, stem cells in their bone marrow still have the capacity to produce foetal haemoglobin.

Some individuals have a hereditary persistence of foetal hemoglobin, and so tap this resource automatically. “They have the sickle cell mutation, but additional mutations result in continued expression of fetal hemoglobin into adulthood,” said Christopher Moxham, PhD, chief scientific officer of Fulcrum Therapeutics. With foetal hemoglobin levels of around 25-30%, he said, enough red blood cells function well enough that patients may become asymptomatic.

The team developed a drug, called FTX-6058, that mimics the effect seen in patients with the hereditary persistence of foetal hemoglobin. It attaches to a protein inside bone marrow stem cells that will mature into red blood cells and reinstates their foetal haemoglobin expression. “What is really key is FTX-6058 upregulates fetal hemoglobin across all red blood cells, a pancellular distribution,” Dr Efremov said. “If some red blood cells did not express this, they could still sickle and cause disease symptoms.” Fulcrum began a phase 1 safety trial in healthy adult volunteers last year after preclinical experiments showed an increase in fetal hemoglobin levels to around 25-30%.

“What distinguishes FTX-6058 is that we are targeting the root cause of sickle cell disease,” Dr Moxham said. “Other drugs approved in this space, particularly since 2019, are treating the disease’s symptoms, either the anemia or the vaso-occlusive crises.”

Preclinical experiments showed that FTX-6058 outperformed another foetal heamoglobin booster, hydroxyurea, approved in the 1990s.

A phase 2 clinical trial is planned for people living with sickle cell disease which should begin by the end of 2021. The researchers are also further characterising the therapeutic molecule. Fulcrum is also considering exploring the use of FTX-6058 in people living with β-thalassemia, a blood disorder in which haemoglobin production is reduced.
