GRAIL Advances the Galleri® Registrational Clinical Trial Program
GRAIL (NASDAQ: GRAL) has announced significant progress in its clinical trials for the Galleri® multi-cancer early detection (MCED) test. The company has completed enrollment of over 35,000 participants in the PATHFINDER 2 study across North America and finished the final study visits for the NHS-Galleri trial with more than 140,000 participants in England.
Results from the first 25,000 PATHFINDER 2 participants are expected in the second half of 2025, while final results from the NHS-Galleri trial are anticipated in 2026. These studies aim to expand GRAIL's clinical validation and performance evidence for the Galleri test, with a focus on diverse participant populations. The data will support GRAIL's premarket approval application to the FDA, which is currently in process under a Breakthrough Device Designation.

Insights
GRAIL's recent developments in its clinical trial program have several important financial implications. The completion of enrollment for the PATHFINDER 2 study and final study visits for the NHS-Galleri trial indicates significant progress toward the company’s goal of achieving FDA premarket approval for the Galleri test. This clinical milestone enhances GRAIL’s credibility and may lead to increased investor confidence.
The scale of these trials, involving over 35,000 participants for PATHFINDER 2 and 140,000 for NHS-Galleri, is substantial. Large-scale trials often generate robust data that can support regulatory submissions and improve market adoption upon approval. Additionally, these achievements may attract strategic partnerships or funding, positively influencing GRAIL’s balance sheet.
However, investors should be mindful of the timeline. Results from the first 25,000 participants in the PATHFINDER 2 study are expected in the second half of 2025 and final results from the NHS-Galleri trial in 2026. The long wait may lead to volatility and speculative trading. In the short term, market sentiment might be cautious, but the long-term prospects seem promising.
The scale and scope of GRAIL’s clinical trials provide a comprehensive assessment of the Galleri test's efficacy and safety. Completing enrollment for PATHFINDER 2 with over 35,000 participants and concluding the NHS-Galleri trial involving 140,000 individuals underline the extensive validation efforts. These studies involve diverse populations, enhancing the generalizability of results.
The modular submission for FDA approval under the Breakthrough Device Designation highlights the innovative nature of the Galleri test. It accelerates the review process, potentially allowing earlier market entry. However, the long timeline before results are available necessitates ongoing scrutiny of interim data and other related studies to ensure positive outcomes.
Key considerations include the test's sensitivity and specificity across different cancers and population subsets. If the Galleri test demonstrates high accuracy and clinical utility, it may revolutionize early cancer detection, offering significant public health benefits and economic savings by reducing cancer treatment costs through early intervention.
The successful enrollment and study progress for GRAIL's trials are strategic milestones that could reshape the market for multi-cancer early detection (MCED) tests. The Galleri test's potential FDA approval would position GRAIL as a leader in this emerging field. The large and diverse trial populations provide robust validation that may support market penetration and adoption.
GRAIL’s emphasis on diversity in its study populations addresses a critical market need. Diverse clinical data can reassure healthcare providers and payers regarding the test's effectiveness across various demographic groups, potentially facilitating broader market acceptance and integration into standard screening protocols.
Moreover, these developments might spur competitive responses from other companies in the MCED space, influencing overall market dynamics. Investors should consider the competitive landscape and GRAIL’s strategic positioning in relation to its rivals. Potential headwinds include regulatory hurdles and the need for extensive education to drive adoption among clinicians and patients.

About the NHS-Galleri Trial (NCT05611632)
In 2020, NHS England selected GRAIL to assist with the
The trial is designed for participants to provide three blood draws over a two-year period, with the first draw taken at enrollment. As a randomized controlled trial, half of the trial participants have received the Galleri test, and half have had their blood sample stored for future analysis. Any participant in the interventional arm with a cancer signal detected result has been referred for further diagnostic workup within the NHS. All other participants and their physicians remain blinded as to which arm of the study they are in. The NHS-Galleri trial design was published in Cancers in 2022.

About Galleri®
The Galleri multi-cancer early detection test is a proactive tool in finding cancer early. With a simple blood draw, the Galleri test can identify DNA shed by cancer cells (unique "fingerprints") to help screen for some of the deadliest cancers that don't have recommended screening today, such as pancreatic, esophageal, ovarian, liver, and others.* The Galleri test can be used to screen for cancer before a person becomes symptomatic, when cancer may be more easily treated and potentially curable. The Galleri test can indicate the origin of the cancer, giving healthcare providers a roadmap of where to explore further. The Galleri test requires a prescription from a licensed healthcare provider and should be used in addition to recommended cancer screenings such as mammography, colonoscopy, prostate-specific antigen (PSA) test, or cervical cancer screening. It is recommended for people over the age of 50, or those with an elevated risk for cancer due to genetics, family history, environmental exposure, or other risk factors.

Important Galleri Safety Information
The Galleri test is recommended for use in adults with an elevated risk for cancer, such as those aged 50 or older. The Galleri test does not detect all cancers and should be used in addition to routine cancer screening tests recommended by a healthcare provider. Galleri is intended to detect cancer signals and predict where in the body the cancer signal is located. Use of Galleri is not recommended in individuals who are pregnant, 21 years old or younger, or undergoing active cancer treatment.
Results should be interpreted by a healthcare provider in the context of medical history, clinical signs and symptoms. A test result of Cancer Signal Not Detected does not rule out cancer. A test result of Cancer Signal Detected requires confirmatory diagnostic evaluation by medically established procedures (e.g., imaging) to confirm cancer.
If cancer is not confirmed with further testing, it could mean that cancer is not present or testing was insufficient to detect cancer, including due to the cancer being located in a different part of the body. False-positive (a cancer signal detected when cancer is not present) and false-negative (a cancer signal not detected when cancer is present) test results do occur. Rx only.
Laboratory/Test Information
The GRAIL clinical laboratory is certified under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) and accredited by the College of American Pathologists. The Galleri test was developed, and its performance characteristics were determined by GRAIL. The Galleri test has not been cleared or approved by the
