RESEARCH PARTNERSHIPS “For the loved ones we've all lost, for the family we can still save, let's make America the country that cures cancer once and for all.”
“Imagine if you all worked together. I’m not kidding.”

MSKCC protocol 08-123. The patient remains on drug with no evidence of disease 24
months after starting treatment. This patient was one of only 2 who responded to drug (of 45
patients). The drug did not achieve it’s pre-trial statistical endpoint (>70% of patients progression free at 2 months).

The Challenge of Trials for Genomically-Defined Populations
• Phase 2 study in advanced BRAF V600E NSCLC• >2,000 subjects screened to enroll 23 patients
• Randomized Phase 3 trial• >15,000 subjects to identify 300 eligible patients• ~14 years projected to complete study
Under a master protocol, patients are screened for various biomarkers and assigned to trials (arms) for drugs that are most likely to be effective
• Patients may have more clinical trial options as there is more efficient use of small biopsy specimens by centrally performing many at the same time
• Patients are enrolled from a large, centrally screened pool, doing away with the need for patients to undergomultiple screenings to enter different trials
Maximize success of the trial by studying subtypes of disease for which targeted therapies should provide dramatic benefit

• Trial is open and enrolling in every state, DC, and Puerto Rico• 50% of the 1100 sites have enrolled at least one patient for
screening
In patients tested so far, the tumor gene variants we are studying are
less common than expected,
from 3.47 percent to zero
The discovery that prevalence rates for tumor gene abnormalities being studied in the trial are lower than expected sheds light on the fact that for several of the treatment arms to reach their 35‐patient goal, we really need to look at tens of thousands of patients
MD reviews results of genomic test performed in CLIA certified/CAP accredited lab
MD determines if drug match exists in protocol
Patient enrolled on study
Matched therapy administered; safety and efficacy outcomes recorded
Data monitoring committee regularly reviews RR of tumor-variant-drug groups
Results released when protocol-specified endpoints met
No match, Rx at MD discretion

Improving quality for Patients, Providers, Researchers
So many questions, so few patients in clinical trials!
Making the most of every opportunity Trial designs to test biology‐driven hypotheses Learning how to learn from clinical care
Sharing is an obligation The power of the many: many patients, crowd‐sourced analyses
