We help pharmaceuticals address two specific challenges

Challenge

CAX Solution

When

Minimize Patient Enrollments Revive ‘Failed’ Trials

Many clinical trials fail to enroll the required # of patients on time

Trials that fail due to unmet efficacy end points are hard to recover from and can be devastating

Identify minimal number of patients needed for a statistically relevant trial; reducing no. of patients to be tested by 20-30%

Identify sub-group of patients that meet efficacy end points and define patient inclusion/ exclusion criteria for a trial targeted at the selected sub-group

Typically, post Phase II Success Typically, post Phase III Failure

CAX Unique Approach Hundreds of machine learning and statistical algorithms are compared to arrive at the most accurate patient selection criteria

How it works

• Client provides de-identified clinical trial data from Phase II/ Phase III trials

• Includes demographic, genetic, clinical, imaging and other biomarker data

• CAX further transforms the data to remove context before sharing with the Solver community

• CAX defines competition to score patients based on their response to a drug

• 300+ Solvers submit 1000+ independent predictive models to score patients and identify the most important patient characteristics

• The top 10 models are selected based on their prediction accuracy

• Heat map of the top 10 models is created

• Business sanity checks are done to further narrow the models

• Results are compared to minimize the statistical variance and improve the reliability of the outcomes

• Outcome of the top models are used to develop a simplified decision tree

• Decision tree paths are labeled as inclusion or exclusion criteria

Compared to traditional analytics, CAX approach is significantly better

Accuracy

Reliability(rigor employed to solve your

problem)

Time(time to deliver value)

Capacity

• Matching current parameters

• Single approach to a problem

• Matching current parameters

Our solvers often exceed accuracy levels in published journals

• Multiple approaches to the same problem

Hundreds of different approaches result in statistically more robust results, especially in cases with limited data efficacy data available from Phase II trials

• 6 weeks• 15-20 weeks

• On-demand

>90% of projects completed with 6 weeks. Traditional analytics teams often take this time to “mobilize resources”

• Allocated by project

Cost• Outcome based

Payment based on achievement of milestones

• FTE / Hour model

As a recent example, the CAX platform was used to predict which patients are likely to have an exacerbation, so that client can select similar patients for future trials

“One of the greatest advantage of the crowdsourcing approach was that there was available talent ready to work on my problem. I can almost guarantee that the crowdsourcing approach dedicated significant more man-hours on this project than I would ever been able to get through internal resources.”

Principal Research Scientist at a Major Pharma company

“The fresh perspective from one of the analysts triggered a key insight that had eluded us”
