PBI-1402: A New Candidate for the Treatment of Anemia.
Bibliographic record
Abstract
Abstract PBI-1402 is an orally active low molecular weight synthetic compound which is currently in a phase Ib/II clinical trial in patients with anemia associated with cancer and/or chemotherapy. PBI-1402 stimulates the in vitro/ex vivo proliferation and maturation of hematopoietic progenitors (erythroid and myeloid populations) with an activity comparable to EPO. Furthermore, an additive effect is observed in combination with EPO. PBI-1402 enhances the differentiation of pluripotent stem cells: CFU-GEMM, CFU-GM with a predominant effect on BFU-E. Clinical phase I study showed that PBI-1402 is devoid of significant side effects. In addition, the clinical phase I results showed statistical increase (100%, p<0.0001) of relative and absolute reticulocyte count in healthy volunteers after 21 days of oral treatment compared to placebo. Preclinical results demonstrated that PBI-1402 yields an increase in erythrocytes in the systemic circulation. In myeloblated mice that received a syngeneic bone marrow transplant, oral treatment with PBI-1402 resulted in a significant increase in peripheral erythrocyte count, hemoglobin, platelet and bone marrow erythroid progenitor cells. PBI-1402 is targeted as an adjunct to cytotoxic drugs, radiotherapy and bone marrow transplantation for the treatment of anemia.

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.
