An update and appraisal of the cilomilast Phase III clinical development programme for chronic obstructive pulmonary disease
Bibliographic record
Abstract
Cilomilast (Ariflo, SB 207499) is an orally active, second-generation phosphodiesterase (PDE) 4 inhibitor that is being developed by GlaxoSmithkline for the treatment of chronic obstructive pulmonary disease (COPD). The results of Phase I and Phase II studies have demonstrated that cilomilast significantly improves lung function and quality of life to a clinically meaningful extent, which has led to a comprehensive Phase III programme of research evaluating efficacy, safety and mechanism of action. However, the results of those Phase III studies are unremarkable and disappointing, raising doubt over the future of cilomilast as a novel therapy for COPD. This review summarizes data obtained from the Phase III clinical development programme, highlights some of the potential concerns both specific to cilomilast and to PDE4 inhibitors in general and assesses the likelihood that cilomilast will reach the market.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
