Methodology of the SORENTO clinical trial: Assessing the efficacy and safety of high exposure octreotide subcutaneous depot in patients with GEP-NETs.
Bibliographic record
Abstract
TPS4178 Background: Somatostatin receptor ligands (SRLs) are first-line standard of care therapies for gastroenteropancreatic neuroendocrine tumors (GEP-NETs), showing efficacy in tumor/symptom control with an established safety profile. Yet, disease progression may occur despite standard-dose SRL treatment, requiring more aggressive and toxic therapies. Retrospective/non-randomized data suggest higher-dose SRLs may benefit patients with GEP-NETs who do not respond to standard-dose treatment and provide improved disease control. Octreotide depot (CAM2029) is a novel high-exposure, subcutaneous (SC) formulation. Clinical trials showed ̃500% higher CAM2029 bioavailability versus octreotide long-acting release (LAR) (Tiberg et al. 2015), and maintenance/reduction of NET symptoms (Pavel et al. 2019). Prospective, randomized data are needed to confirm the efficacy/safety of novel SRLs with higher bioavailability such as CAM2029, vs standard-dose SRLs including octreotide LAR and lanreotide Autogel (ATG). Methods: SORENTO is a randomized, multi-center, open-label, active-controlled Phase 3 trial, aiming to enroll 302 adults with GEP-NETs. Key eligibility criteria: advanced, well-differentiated NET of GEP/presumed GEP origin; ≥1 measurable SR positive (by nuclear imaging) lesion according to RECIST 1.1; no or < 6 months consecutive treatment with long-acting SRLs. Notably, patients with Grade 3 GEP-NETs (excluded by CLARINET/PROMID trials) are eligible. Patients will be randomized 1:1 to CAM2029 20 mg Q2W, or active comparator (octreotide LAR 30 mg intramuscular or lanreotide ATG 120 mg SC, Q4W). CAM2029 self/carer administration is allowed after ≥3 successful supervised administrations. Randomization stratified by: histological grade, tumor origin, intended comparator. Primary outcome: progression free survival (PFS; time from randomization to date of first documented disease progression [RECIST 1.1] or death), assessed by a Blinded Independent Review Committee. The study is powered to detect a hazard ratio of 0.65. Key secondary outcomes: overall survival; response rate; rescue medication use; patient satisfaction; adverse events. After primary PFS analysis, patient overall survival will be followed for up to 2 years. If CAM2029 displays superiority in the primary analysis, the comparator group may switch to CAM2029 20 mg Q2W. Patients in any treatment group experiencing progressive disease in the randomized part of the study may proceed to an open-label extension with intensified CAM2029 treatment, to investigate effects of higher frequency dosing. First patient randomized in Nov-2021, with readout (following 194 events) expected by 2024 end. This novel head-to-head superiority trial is anticipated to demonstrate the potential benefits of CAM2029 as a first line-therapy in patients with well-differentiated GEP-NETs. Clinical trial information: NCT05050942.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
