To overcome the historical issue of oncolytic viruses being sequestered by the liver, Accession re-engineers a human virus so it cannot infect any human cells. Only after this safety step is it re-targeted to infect only cancer cells, ensuring precise delivery and avoiding systemic side effects.

Previous IL-2 therapies from companies like Nektar and Synthorix broadly targeted beta and gamma receptors, which proved clinically ineffective. Synthakyne represents a strategic shift, designing molecules to selectively target the trimeric alpha-beta-gamma receptor found on potent, antigen-activated T cells, avoiding widespread, toxic stimulation.

The drug exhibits a multimodal mechanism. It not only reverses chemoresistance and halts tumor growth but also 'turns cold tumors hot' by forcing cancer cells to display markers that make them visible to the immune system. This dual action of direct attack and immune activation creates a powerful synergistic effect.

To overcome on-target, off-tumor toxicity, LabGenius designs antibodies that act like biological computers. These molecules "sample" the density of target receptors on a cell's surface and are engineered to activate and kill only when a specific threshold is met, distinguishing high-expression cancer cells from low-expression healthy cells.

Despite pancreatic cancer being notoriously difficult, Actuate prioritized it as a lead indication for strategic reasons. Strong preclinical data allowed the company to bypass later-line trials and move directly into a first-line setting, a 'leapfrog' maneuver that significantly accelerates the drug's overall development and regulatory path.

While personalized cancer vaccines require extracting and processing a patient's tumor, Create Medicines' in vivo approach is entirely off-the-shelf. By delivering the programming directly into the body, they enable the patient's own immune system to do the complex, personalized work of attacking the cancer itself.

Accession's second product is a bispecific antibody that binds to all cancer cells. While this would be dangerously toxic if delivered systemically, their targeted virus delivery system ensures it is only produced inside the tumor. This strategy makes previously "undruggable" therapeutic concepts viable.

Instead of just killing cancer cells, the primary mechanism is to insert a gene that forces the infected cell to produce and secrete a potent drug, like an anti-PD-L1 antibody. This creates a hyper-concentrated therapeutic effect directly in the tumor microenvironment, a concept termed "molecular surgery."

The successful KEYNOTE-564 trial intentionally used a pragmatic patient selection model based on universally available pathology data like TNM stage and grade. This approach avoids complex, inconsistently applied nomograms, ensuring broader real-world applicability and potentially smoother trial execution compared to studies relying on more niche scoring systems.
