Meet Valar Labs, a biotech startup focused on revolutionizing cancer care through AI technology, has introduced a new tool designed to predict treatment outcomes more accurately. This innovative approach aims to save valuable time for patients by identifying the most effective therapies from the outset. The company has secured $22 million to expand its reach to new cancers and therapies.

The landscape of cancer treatment is complex, with each type of cancer requiring unique approaches honed over years of clinical testing. However, many treatments still involve a trial-and-error approach, which can be time-consuming and stressful for patients. Valar Labs seeks to streamline this process, beginning with a focus on bladder cancer and a common treatment called BCG therapy, which has a 50% success rate. By using AI to predict treatment responses, Valar aims to improve these odds and reduce the time spent on ineffective therapies.

The Valar team, led by CEO Anirudh Joshi, met at Stanford while researching AI applications in clinical decision-making. They discovered that many cancer patients face uncertainty regarding their treatment plans, often resorting to trial-and-error methods. Valar’s goal is to provide more informed decisions, particularly in cases where only half of the patients respond to standard treatments.

Valar’s first product, Vesta, targets this issue by utilizing AI to analyze histology images from cancer patients. This process involves a computer vision model trained on thousands of high-resolution images of affected tissue, which helps identify cellular-level changes that are critical in predicting treatment outcomes. The AI extracts numerous features from these images, some of which pathologists may visually recognize but cannot quantify precisely.

The aim is not to replace pathologists but to augment their capabilities, providing them with detailed, quantifiable data to support their assessments. This “smart microscope” approach enhances the precision of measurements related to cellular damage, immune responses, and other critical indicators of disease progression or inhibition.

The predictive power of Valar’s models surpasses traditional risk factors such as age, health history, and smoking status. These AI-driven insights are intended to complement, rather than replace, existing metrics, providing a more comprehensive view of a patient’s likelihood to respond to specific treatments.

Valar Labs emphasizes the interpretability of its results, ensuring that both doctors and patients understand the underlying reasons behind the AI’s predictions. This transparency is crucial for gaining trust and ensuring that the technology is effectively integrated into clinical practice.

The startup was founded in 2021, as Valar Labs has focused its initial efforts on developing and validating its image analysis model and its first clinical application for BCG therapy in bladder cancer patients. Their studies, conducted in collaboration with medical centers worldwide, have demonstrated the tool’s effectiveness in identifying patients with a higher risk of non-response to BCG therapy, potentially guiding them towards alternative treatments sooner.

With the recent $22 million Series A funding led by DCVC and Andreessen Horowitz, Valar is poised to commercialize Vesta and expand its application to other types of cancer. COO Damir Vrabac noted that their commercial lab model follows the precedent set by genomic testing, aiming to integrate seamlessly into the healthcare system without adding friction. This approach should enable cost coverage by insurance providers and ultimately reduce overall healthcare costs by avoiding ineffective treatments.

Valar Labs is committed to providing a powerful tool in the fight against cancer, enhancing the decision-making capabilities of healthcare professionals and improving the treatment journey for patients.
