January 23, 2026, became a landmark date for digital pharmaceuticals. The U.S. Food and Drug Administration (FDA) issued an official Investigational New Drug (IND) clearance for clinical trials of ISM8969. Designed to combat Parkinson’s disease, this therapeutic agent was developed, modeled, and optimized using generative artificial intelligence.
The Goal: Stopping Brain Inflammation
The drug’s developer, Insilico Medicine, positions the new molecule as a potentially “best-in-class” oral treatment for neurodegenerative disorders.
The mechanism of action of ISM8969 targets the inhibition of the NLRP3 protein. Excessive activation of this protein leads to the release of pro-inflammatory cytokines, causing chronic neuroinflammation and neuronal death—processes underlying both Parkinson’s and Alzheimer’s diseases.
A key advantage achieved through AI is the molecule’s ability to cross the blood-brain barrier (BBB):
“Most existing drugs are unable to cross the barrier separating the brain from the bloodstream. AI technologies allowed scientists to design a molecular structure that freely penetrates brain tissue while simultaneously inhibiting the NLRP3 protein.”
Preclinical studies in mice demonstrated that the drug not only reaches its target in the CNS but also significantly slows disease progression, improving motor functions and physical strength in the animals.
Acceleration by Orders of Magnitude
The drug was created using the generative platform Pharma.AI (Chemistry42 module). The use of neural networks reduced the development cycle to record-breaking times. While traditional candidate discovery takes an average of 4.5 years, Insilico completed the task in 12–18 months, synthesizing only a limited number of molecules for testing.
“We hope to induce a genuine paradigm shift with AI breakthrough in novel drug discovery. We are excited to get the greenlight from FDA to advance this novel therapeutic to human clinical trials.”

Phase I clinical trials, set to take place in the U.S., will evaluate the safety, tolerability, and pharmacokinetics of ISM8969 in healthy volunteers.
Commercialization and Partnership
To bring the drug to the global market, Insilico Medicine has entered into a strategic co-development agreement with Hygtia Therapeutics.
- The parties have split global rights to the program 50/50.
- Insilico is eligible to receive up to $66 million in upfront and milestone payments.
- The partnership covers registration, manufacturing, and commercialization of the product worldwide.
Technological Roots
Insilico Medicine Founder and CEO Alex Zhavoronkov emphasized the role of technological partnership in the company’s success. He noted that Insilico’s history began at the NVIDIA GTC conference and thanked Jensen Huang and the NVIDIA team for early access to hardware that made deep learning possible.
Today, thanks to these technologies, Insilico’s portfolio includes 27 candidates in development and 11 programs that have reached the clinical stage.
