Prelude Therapeutics is a clinical-stage precision oncology company that has been making significant strides in developing novel cancer treatments. Founded in 2016, the company has built an impressive pipeline of drug candidates, leveraging its expertise in cancer biology and medicinal chemistry to create a diverse portfolio targeting various oncogenic pathways.

Business Overview and History

Prelude Therapeutics was established with the goal of addressing the unmet medical needs in the oncology space. The company's approach focuses on developing therapies that target primary and secondary resistance mechanisms, aiming to serve patients with limited or no treatment options. Since its inception, Prelude has made remarkable progress in advancing its pipeline, receiving multiple IND clearances from the FDA and successfully initiating several clinical trials.

In its early years, Prelude faced typical challenges of a startup biotech company, including uncertainties in the drug development process, competition from other companies developing similar technologies, and the need to secure adequate funding to support its operations. Despite these obstacles, the company persevered and made significant strides in its research and development efforts.

One of Prelude's key assets is its first-in-class, highly selective SMARCA2 degrader, PRT3789. This molecule has demonstrated promising anti-tumor activity and a favorable safety profile in early-stage clinical trials for patients with SMARCA4-mutated cancers, a subset of non-small cell lung cancer (NSCLC) and other solid tumors. Prelude has presented interim data from the ongoing Phase 1 study of PRT3789, showcasing objective responses in patients with SMARCA4-mutated NSCLC and esophageal cancer. The company believes PRT3789 has the potential to benefit up to 10% of non-small cell lung cancer patients in the United States, as well as patients with SMARCA4 mutations in other tumor types.

In addition to PRT3789, Prelude is advancing its CDK9 inhibitor, PRT2527, which has the potential to become a best-in-class treatment for hematological malignancies. Preclinical studies have shown that PRT2527 can effectively deplete oncogenic drivers, such as MYC and MCL1, while demonstrating a favorable safety profile. The company has completed a Phase 1 multi-dose escalation study in solid tumors and is now focusing on the development of PRT2527 in hematologic malignancies, with plans to report interim Phase 1 data in Q4 2024. PRT2527 has demonstrated high target engagement and a potentially better tolerability profile compared to less selective CDK9 inhibitors.

A significant milestone in Prelude's history was the initiation of a multi-year, multi-program collaboration agreement with AbCellera Biologics in 2023. This partnership allowed Prelude to combine its small molecule and degrader expertise with AbCellera's antibody capabilities to develop precision antibody drug conjugates (ADCs). This program leverages Prelude's expertise in selective degraders as payloads for novel antibodies targeting tumor-specific antigens, with the potential to extend the therapeutic utility of this class.

In 2024, Prelude encountered a setback when it decided to discontinue the development of its CDK46 inhibitor, PRT1419, in order to prioritize its CDK9 inhibitor, PRT2527. This decision reflects the company's ability to adapt and focus its resources on the most promising programs in its pipeline.

Prelude's pipeline also includes PRT7732, another oral SMARCA2 degrader that recently received IND clearance and began Phase 1 testing in SMARCA4 mutated cancers. This further demonstrates the company's commitment to developing novel therapies targeting the SMARCA family of proteins.

Throughout its history, Prelude has faced the common challenges of a clinical-stage biotech company, including the need to manage its cash runway, navigate the regulatory landscape, and prioritize its research and development efforts. However, the company has also achieved several key milestones, including the advancement of multiple programs into the clinic and the establishment of strategic partnerships to enhance its capabilities.
