Phase II Evaluation of Lonidamine in Patients with Advanced Malignancy
Bibliographic record
Abstract
Lonidamine, a substituted indazole carboxylic acid with unique effects on cellular respiration, was studied in 27 patients with advanced malignancies. Of the 18 evaluable patients, 5 had small-cell lung cancer, 3 had non-small-cell lung cancer, 3 sarcoma, 2 breast cancer, and 5 other tumour types. All but 1 had had extensive prior treatment. A partial response was seen in 1 patient with metastatic synovial sarcoma, and tumour growth inhibition was demonstrated in 2 other cases. The major toxicity encountered was myalgia (66.6%) which was incompletely ameliorated by prednisone and required dose reduction in 2 patients and cessation of drug in 3. Other toxicities included auditory changes, anorexia, nausea and vomiting, diarrhoea, skin sensitivity, and conjunctivitis. No added toxicity was seen, when Lonidamine was combined with other chemotherapeutic agents. No correlation between Lonidamine dose and serum lactate levels was seen, although 4 patients showed a progressive increase in lactate levels over time, thought to be related to their increasing tumour burden. 5 patients demonstrated a dramatic fall in serum testosterone levels 4-8 weeks after starting Lonidamine which was accompanied by an increase in luteinizing hormone levels in 3 patients. In summary, modest antitumour activity was demonstrated in 3 patients; moderate toxicity was seen in most patients, but was usually tolerable. Further studies of Lonidamine are warranted in less heavily treated patients, alone or in combination with other chemotherapeutic agents.

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.
