In the previously published PATHFINDER study, adding Galleri to standard of care cancer screening more than doubled the overall number of cancers detected by screening. In PATHFINDER 2, adding Galleri to standard of care screening demonstrated substantially greater additional cancer detection than in PATHFINDER.

In PATHFINDER, Galleri demonstrated a positive predictive value (PPV), or likelihood that a positive Galleri test was confirmed to be cancer, of 43%; specificity of 99.5%; and 88% cancer signal origin (CSO) accuracy. Data from evaluable PATHFINDER 2 participants with 12 months of follow-up showed a substantially higher PPV than that observed in the PATHFINDER study. CSO accuracy and specificity were consistent with that observed in the PATHFINDER study.

There were no serious safety concerns reported in PATHFINDER 2.

"We are delighted to see very encouraging performance of the Galleri MCED test as a cancer screening tool in broad intended use populations of asymptomatic adults over 50 years of age in both the PATHFINDER 2 study and the NHS-Galleri trial’s prevalent screening round," said Josh Ofman, MD, MSHS, President at GRAIL. "We would like to extend our sincere gratitude to all of the participants and investigators in both of these pivotal studies, who are collectively helping to realize the potential of this groundbreaking technology for population-scale multi-cancer early detection and move the field forward. We look forward to sharing the detailed PATHFINDER 2 data at a medical congress later this year."

PATHFINDER 2 study results will be submitted to the U.S. Food and Drug Administration (FDA) as part of the Galleri premarket approval application (PMA), along with data from the prevalent screening round of the NHS-Galleri trial. In addition, GRAIL will submit to the FDA bridging analyses to compare performance of the version of Galleri used in the PATHFINDER 2 study and the NHS-Galleri trial to the updated version that GRAIL plans to submit to the FDA for premarket approval. The PMA for Galleri is currently in process with a modular submission under a Breakthrough Device Designation from the FDA. GRAIL expects to complete the PMA modular submission in the first half of 2026.

Detailed results from the PATHFINDER 2 study will be submitted for presentation at a leading international oncology meeting before the end of the year.

About the PATHFINDER 2 Study (NCT05155605)
PATHFINDER 2 is a prospective, multi-center, interventional study evaluating the safety and performance of Galleri in approximately 35,000 individuals aged 50 years and older who are eligible for guideline-recommended cancer screening in the United States. The primary objectives of the study are 1) to evaluate the safety and effectiveness of the Galleri MCED test based on the number and type of diagnostic evaluations performed in participants who receive a cancer signal detected test result, and 2) to evaluate the performance of the Galleri MCED test across various measures, including PPV, negative predictive value (NPV), sensitivity, specificity, and CSO prediction accuracy. Participants who receive a cancer signal detected result undergo additional diagnostic testing based on the predicted CSO to determine if a cancer is present. Secondary objectives include utilization of guideline-recommended cancer screening procedures after use of the MCED test, and participant reported outcomes (PRO) over several time points, including an assessment of participants’ anxiety and satisfaction with the MCED test.

All patients treated with TG4050 in the Phase I part of the trial remained disease-free after a minimum of two years of follow-up, confirming clinical proof of principle. Translational data showed sustained T cell responses at 24 months in these patients. The results, which met all trial endpoints including safety, feasibility, immune activation and disease-free survival (DFS, defined as survival without recurrence or death for any cause), were presented in an oral presentation at the recent American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) (ASCO 2025) annual meeting.

Transgene expects to complete randomization of all patients in the Phase II part by the end of 2025, following a second screening of patients conducted after surgery and adjuvant (chemo)radiotherapy. These screenings represent key steps during which patients are evaluated to determine whether they meet the eligibility criteria to participate in the clinical trial. In total, approximately 80 patients with a complete response to adjuvant therapy are anticipated to be enrolled and subsequently randomized in the Phase I/II trial. First immunogenicity data from the Phase II part of the trial are expected to be available in H2 2026, and preliminary efficacy data are expected in H2 2027.

Dr. Emmanuelle Dochy, MD, Chief Medical Officer of Transgene added: "Timely completion of first patient screening of the Phase II part of our Phase I/II trial is an important milestone for Transgene and brings us one step closer to providing a new treatment option for patients living with operable squamous head and neck cancer. With meaningful data readouts expected over the next two years, we are preparing to deliver important data for TG4050 and at the same time explore its wider potential. We are grateful to the patients, their families, investigators, and clinical staff whose commitment made this achievement possible."

Dr. Alessandro Riva, CEO of Transgene commented: "The positive results from the Phase I part of our TG4050 trial support the strong potential of our myvac platform. The successful completion of the first screening of the randomized Phase II part in less than a year and ahead of schedule underscores the investigators’ commitment to rapidly advance the development of TG4050. In the ongoing Phase II part of the trial, we have been able to scale efficiently, strengthen our manufacturing capabilities and operate with the agility needed to lead in a highly competitive and fast-moving environment.

The myvac individualized cancer vaccine platform can be applied across a range of solid tumors where in many cases a significant unmet medical need remains. Consequently, Transgene is starting initial preparations for a new Phase I trial in a second, undisclosed indication in an early treatment setting, with the aim to initiate the trial in Q4 2025."
