SOUTH SAN FRANCISCO, Calif., Dec. 07, 2016 (GLOBE NEWSWIRE) -- Origent Data Sciences, Inc. (Origent) and Cytokinetics, Inc. (Nasdaq:CYTK) today announced results from the first part of a research collaboration to refine and prospectively validate an Origent computer model to predict the course of ALS disease progression leveraging data from Cytokinetics’ clinical trials of tirasemtiv. The poster, presented by David L. Ennist, Ph.D., MBA, Chief Science Officer, Origent Data Sciences and Jinsy A. Andrews, M.D., Director of Neuromuscular Clinical Trials, Columbia University, at the 27th International Symposium on ALS/MND in Dublin, Ireland, showed that the Gradient Boosting Machine (GBM) algorithm was the optimal model to predict slow vital capacity (SVC) at times subsequent to baseline and that forced vital capacity (FVC) records could be used to predict slow vital capacity (SVC) scores of ALS patients using this machine learning technique.
“We are pleased to have completed this first-ever step toward using machine learning models for prospectively predicting ALS outcomes and disease progression in late-phase human clinical trials and look forward to continuing this important collaboration with Cytokinetics,” said Dave Ennist, Chief Science Officer, Origent Data Sciences.
“These data bring us one step closer to prospectively validating the Origent predictive model using datasets from BENEFIT-ALS and VITALITY-ALS,” said Jinsy Andrews, M.D., Director of Neuromuscular Clinical Trials, Columbia University and Medical Monitor for VITALITY-ALS. “We hope that predictive algorithms arising from this research collaboration may ultimately accelerate clinical trials in patients with ALS by using virtual control arms.”
The objective of this phase of the research collaboration was to develop a model that uses baseline patient characteristics including the results of a screening visit to predict SVC at subsequent times using the PRO-ACT (Pooled Resource Open-Access ALS Clinical Trials) database, a platform that houses the largest ALS clinical trials dataset. The database was used to compare three different predictive models with the GBM algorithm proving to outperform other models in predicting SVC. Using the GBM model, the researchers demonstrated that 22 baseline characteristics including FVC could be used to train a model that predicts SVC at subsequent times. Additionally, the researchers showed that baseline FVC and SVC were highly correlated measures of vital capacity. Finally, the data identified and weighted the predictive value of several variables, demonstrating that FVC at baseline was the most important predictor of vital capacity at subsequent times in patients with ALS.
About the Research Partnership
Funded by Origent’s receipt of a grant from The ALS Association, this joint research program is designed to enable the first prospective validation of predictive models in a clinical trial setting. Previously, the Origent models predicting both function and survival of ALS patients have been validated using internal and retrospective external datasets. Origent will first seek to confirm the retrospective external validation of the existing predictive models (including the ALSFRS-R, respiratory, gross, fine, and bulbar sub-scores, slow vital capacity (SVC) and survival models) using baseline characteristics data from BENEFIT-ALS, Cytokinetics’ completed Phase 2b trial of tirasemtiv, a fast skeletal muscle activator which is being developed for the potential treatment of ALS. If these retrospective validations are confirmed, Origent plans to prospectively validate the models with data to be provided by Cytokinetics following the completion of VITALITY-ALS, an ongoing Phase 3 clinical trial designed to assess the effects of tirasemtiv versus placebo on SVC and other measures of skeletal muscle strength in patients with ALS.
About Origent Data Sciences
Origent Data Sciences, Inc. is a spinoff of Sentrana, Inc., a pioneer in the field of Precision Sales and Marketing and winner of the DREAM Phil Bowen ALS Prediction Prize4Life Challenge. Since 2004, Sentrana has been a market leader in operationalizing new applications using predictive technologies. Founded in 2013, Origent has become the market leader in patient-level predictive modeling and has developed a number of new applications to manage and reduce drug development risks through better foresight. Rather than considering a similar historic patient to act “the same” as a current patient, Origent treats and models each individual patient separately, predicting their behavior individually. By modeling patient-level dynamics rather than the characteristics of a population, Origent’s tools uncover a deep level of insight that allows biostatisticians and researchers to gain clearer understanding and greater knowledge from their data.

Cytokinetics is a late-stage biopharmaceutical company focused on discovering, developing and commercializing first-in-class muscle activators as potential treatments for debilitating diseases in which muscle performance is compromised and/or declining. As a leader in muscle biology and the mechanics of muscle performance, the company is developing small molecule drug candidates specifically engineered to increase muscle function and contractility. Cytokinetics’ lead drug candidate is tirasemtiv, a fast skeletal muscle troponin activator, for the potential treatment of ALS. Tirasemtiv has been granted orphan drug designation and fast track status by the U.S. Food and Drug Administration and orphan medicinal product designation by the European Medicines Agency for the potential treatment of ALS. Cytokinetics retains the right to develop and commercialize tirasemtiv, subject to an option held by Astellas Pharma Inc. Cytokinetics is also collaborating with Astellas to develop CK-2127107, a fast skeletal muscle activator, for the potential treatment of spinal muscular atrophy, chronic obstructive pulmonary disease and ALS. Cytokinetics is collaborating with Amgen Inc. to develop omecamtiv mecarbil, a novel cardiac muscle activator, for the potential treatment of heart failure. Amgen holds an exclusive license worldwide to develop and commercialize omecamtiv mecarbil and Astellas holds an exclusive license worldwide to develop and commercialize CK-2127107. Both licenses are subject to Cytokinetics' specified development and commercialization participation rights. For additional information about Cytokinetics, visit http://www.cytokinetics.com/.
