A multi-centre, open-label study to assess the safety of Stimuvax (BLP25 liposome vaccine or L-BLP25) in non-small cell lung cancer (NSCLC) patients (pts) with unresectable stage III disease
Bibliographic record
Abstract
3075 Background: L-BLP25 is an innovative cancer vaccine that incorporates a synthetic MUC1 lipopeptide in a liposomal delivery system. L-BLP25 is expected to elicit an immune response to cancer cells that express MUC1. Previous clinical studies have demonstrated that L-BLP25 has the potential to extend survival of pts with stage IIIB locoregional NSCLC (Butts C et al., JCO 2005; 23:6674–6681). The present ph I-II study was designed to assess the safety of the current formulation of L-BLP25 using a monophosphoryl lipid A in pts with unresectable stage IIIA and stage IIIB NSCLC. Methods: Pts with stable disease or an objective response to upfront radical therapy with chemoradiation for unresectable stage III NSCLC, plus ECOG 0–1 were eligible. All pts were vaccinated according to a previously described schedule (1). Maintenance immunizations were administered every 6-wks until disease progression. Primary and secondary endpoints were safety and survival respectively. Results: Twenty-two pts were recruited at 7 sites in Canada. 16 pts were evaluated for this interim safety analysis (8 stage IIIA, 8 stage IIIB, median age; 57, ECOG 0 56%, concurrent chemotherapy; 93.8%). Thirteen pts had a partial response and 3 had stable disease following chemoradiation. Thirteen pts experienced an adverse event (AE) during the first 4 vaccinations of which 7 pts had a L-BLP25 related adverse event. Grade 1/2 AEs related to L-BLP25 ≥10% included fatigue, dyspnea, insomnia, anorexia, headache, diarrhea, paresthesia, abdominal pain, influenza-like illness, urinary tract infection and peripheral neuropathy. No pts discontinued L-BLP25 due to an AE and no grade 3/4 AEs related to L-BLP25 were reported. Six pts (37.5%) had an injection site reaction. As of September 2006, 10 pts were still on study treatment. Conclusions: This formulation of L-BLP25 was well tolerated and the side effect profile was similar to that seen in previous studies (1). A controlled global multi-center phase III trial is underway to further evaluate L-BLP25 in this patient population. No significant financial relationships to disclose.

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.
