Network-Integrated Platform for Clinical Trial Navigation from the New South Wales Early Phase Clinical Trials Alliance

Purpose: Access to early-phase clinical trials (EPCT) is increasingly constrained by delays in genomic testing and lack of coordinated system-level navigation. The New South Wales Early Phase Clinical Trials Alliance (NECTA) was established to improve EPCT access. Practical Assessment of NECTA Network Assistance in Cancer Outpatient Trials Access (PANNA-COTA) prospectively evaluated whether integrating circulating tumor DNA (ctDNA) profiling with a real-time, cross-site molecular tumor board (MTB) facilitates EPCT enrollment. Patients and Methods: In this multicenter prospective study across nine NECTA sites, patients referred for EPCT consideration underwent ctDNA testing using the Guardant360 74-gene assay. The results were reviewed at a fortnightly MTB incorporating cross-site trial mapping and dynamic eligibility review. The primary endpoint was proportion enrolled into EPCTs. Secondary endpoints included ctDNA findings and trial outcomes. Results: Of 104 consented participants, 101 were eligible. Participants had advanced, heavily pretreated solid tumors; 48% lacked prior tumor next-generation sequencing. ctDNA alterations were detected in 85%, with actionable alterations in 44%. Therapeutic options were identified in 88%, and EPCTs were recommended in 76%. Despite this, only 7% of participants received genomically matched therapy. In contrast, 37% enrolled in EPCTs within 3 months and 47% overall [95% confidence interval (CI), 0.37–0.56]. Among evaluable participants on trial, the disease control rate was 81% and objective response rate was 33%. Conclusions: PANNA-COTA demonstrates that integrating liquid biopsy with real-time, network-level trial navigation enables high rates of EPCT enrollment despite low rates of genomically matched therapy. These findings indicate that clinical trial access is influenced by navigation, eligibility, and system-level coordination rather than genomic actionability alone.
