Abstract P2-09-01: MBC alliance: Coordinating metastatic research from lab bench to clinical trials
Bibliographic record
Abstract
Abstract The Metastatic Breast Cancer (MBC) Alliance[1] consists of non-profit advocacy, funding organizations and industry partners who seek to transform and improve the lives of women and men living with MBC. There is no cure for MBC and metastasis is the cause of virtually all breast cancer deaths. One objective of the Alliance is to understand the MBC research landscape from basic lab research through translational and clinical trials, to epidemiology, quality of life and patient reported outcomes. The MBC Alliance partnered with the International Cancer Research Partnership (ICRP[2]), an alliance of governmental and charitable organizations from the USA, Canada, Europe, Australia and Japan that fund regional, national and international cancer research grants and awards. The ICRP database of member’s funded grants contains >60,000 grants since 2000, from >80 member organizations, totalling over $14 billion USD. Each project is coded to a Common Scientific Outline (CSO), a classification system of broad areas of cancer research. Objective: To review the last ten years of breast cancer research grant funding related to metastasis and clinical trials to identify the most promising molecular targets, pathways and therapeutics in development for MBC. Methods: ICRP partner-funded grants related to MBC were queried from the ICRP database and clinical trials were queried from Clinicaltrials.gov and breastcancertrials.org. We also conducted interviews with 75 experts including advocates, scientists, clinicians, and leaders of professional societies and cooperative groups. The database searches resulted in a pool of 150 open clinical trials for MBC and 17,985 breast cancer-relevant grant awards. Relevant grant awards and clinical trials were then coded with the assistance of keywords and manual review, to one or more, of 6 categories relevant to the hallmarks of cancer (Hanahan & Weinberg[4]) and metastasis (Steeg[5]). Results: The ICRP database contained 2,250 unique awards related to MBC. The awards are predominantly basic research (70%) and translational (24%) and that profile has not changed significantly over a 5-year period 2008-2012. Awards active in 2012/2013 show that the main areas of focus are: i) early steps to invasion (10%) and, ii) metastatic colonization (15%). Data from 130 trials have been assigned to the Hanahan/Weinberg framework: sustaining proliferative signal, resisting cell death, enabling replicative mortality, genome instability and mutation, tumor promoting inflammation, activating invasion and metastasis, avoiding immune destruction, and other categories like cancer stem cells. Within these categories, the molecular targets of the drugs being used in the trial were further subdivided (e.g., PI3, RAF, CDK). Of the trials analyzed, 71 were Ph I or PhI/II, 47 Ph II and 11 Ph III. Conclusion: Using publicly available databases we were able to develop a comprehensive list of molecular targets, pathways and therapeutics for MBC that will enable improved coordination of MBC research.

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; both teacher heads agree on what is shown here.
