Progression-free Survival Disease-Specific Survival
Joseph Connors, 2012 (unpublished)
Clinical aspects of HL• Common cancer in younger people
• In about 20-25%, primary therapy with ABVD will fail to cure the patients
• High-dose therapy (autoBMT) salvages ~ 50%
• Late toxicities are a problem and thus it would be ideal if we could identify those patients who are being over-treated, in addition to those patients destined to fail their primary treatment
• Clinical translation will require that we identify robust biomarkers that can predict both treatment success and treatment failure

Can we translate biomarker discovery in Hodgkin lymphoma into the clinic?
2011
There is a clear clinical need
• The only tool to inform on an expectation of survival in CHL is the International Prognostic Score (IPS)
• This is only used to design and interpret clinical trials and is NOT used to make treatment decisions for individual patients
• No biological tool is available to reproducibly assign risk or be used as a predictive test on which up-front treatment decisions could be made
Hodgkin lymphoma: The current state of play
• 10-20% of patients with advanced stage CHL succumb to disease
• “One size fits all” approach to treatment
• Lack of reliable tests at diagnosis that can guide management
Scott and Gascoyne, 2013
At the heart of the debate
• There are differing opinions about the up-front chemotherapy regimen for advanced-stage classical HL
• To some extent this represents a European vs North American bias (ABVD vs escalated BEACOPP)
• ABVD fails to cure a sizable minority of patients while escBEACOPP visits unnecessary toxicity on a significant percentage of patients
Study outline• Develop a gene-expression based predictor of OS
in advanced stage CHL treated with standard intensity treatment
• Train on data from a phase III randomized control clinical trial (E2496)
• Validate in an independent cohort treated with ABVD, enriched for primary treatment failure and including a weighted analysis
LI Gordon et al, JCO 2013, 31: 684-91DW Scott et al, JCO 2013, 31: 692-700
The E2496 intergroup trial• Phase III randomized controlled trial comparing
ABVD and Stanford V (n ~ 854 patients)
• Locally extensive and advanced stage cHL
• Identical outcomes between the 2 arms– FFS and OS

Where does it stand?• An internally validated prognostic test for ABVD
treated patients
• Requires external validation
• Requires testing in patients treated with other regimens
• The real value is in a predictive test

Target subjects for biological studies
Other predictors in use
• PET scan after 2 cycles– Defines a high-risk group– Studies ongoing to determine predictive value– “Penalty” for not being at diagnosis
• Opportunity to correlate the NanoString predictor with PET results– Intergroup trial (SWOG 0816) (Phase II Trial)– BC Cancer Agency data
Scott and Gascoyne, 2013
Take home messages
• A fundamental understanding of the biology & genomics of CHL clearly informs on potential diagnostic & prognostic strategies
• Doing science in the context of a clinically relevant question provides value-added information
• Clinical translation using robust technologies that impact treatment decision making is the path forward, even for relatively low incidence cancers
