Why Do We Need Separate Clinical Trials for Older Adults? Arti Hurria, MD Director, Cancer and Aging Research Program Associate Professor City of Hope US Population Age > 65 (millions) Year U.S Census Bureau, 2010 Cancer and Aging Rates per 100,000 Population 60% of cancer occurs in people > age 65 Age Groups CDC, Morbidity and Mortality Weekly Report, 2013 Cancer and Mortality 31% 69% Age < 65 Age ≥ 65 Majority of Cancer Deaths Occur in Older Adults Howlader et al., SEER Cancer Statistics Review 1975-2010 Life Expectancy is Increasing Age Year National Vital Statistics Report Projected Rise in Cancer Incidence from 2010 to 2030 Cancer Incidence (million) 67% in patients 65+ 11% in patients <65 Year Smith et al, J Clin Oncol, 2009 The Population is Aging The Number of Older Adults With Cancer is on the Rise Are we prepared?

JCO 2004 The Questions We Face in Daily Practice are Not Addressed in Clinical Trials Who will die of disease vs. with disease? Who is vulnerable to cancer therapy toxicity? How should I adjust the therapy based on: - their functional status - their comorbid illnesses - their social situation U13: Background Foundation for research planning in Cancer & Aging - 1997 Geriatric Oncology Education Retreat - 2001 NIA/NCI workshop “Exploring the Role of Cancer Centers for Integrating Aging and Cancer Research” Advances in evidence based knowledge in Geriatric Oncology Training and mentoring is essential to move the field forward - ASCO/ Hartford combined fellowship in Geriatric Oncology - The Cancer & Aging Research Group Planning for the Next 10 Years: U13 Grant “Geriatric Oncology Research to Improve Clinical Care” Collaboration NIA, NCI, The Cancer & Aging Research Group Mission: 1. 2. 3.

Disseminate Key Publications from the U13 JNCI, 2012 Nat Rev Clin Oncol, 2012 J Natl Compr Canc Netw, 2012 Conference 2: Design and Implementation of Therapeutic Clinical Trials for Older and/or Frail Adults with Cancer Goals: 1. Identify gaps in knowledge of cancer therapy in older adults 2. Study design of therapeutic clinical trials 3. Methods to optimize patient accrual 4. Propose opportunities for multidisciplinary studies 5. Disseminate Two Major Deficiencies Need to: accrue older adults to existing clinical trials develop specific trials for the “oncologically frail” older adults Phase III Trial Randomize Standard Clinical Trial Design: Is More Better? Arm A Drug X Arm B Drug X + Y Patients age ≥ 65 not enrolled onto the study due to: 1) Doctors’ concerns regarding toxicity 2) Patient may not be “fit” for the study Kemeny et al., JCO 2003 Barriers to Participation of Older Women with Breast Cancer in Clinical Trials CALGB Retrospective Case-Control study 77 patients age ≥ 65 vs. 77 patients age < 65 with breast cancer Matched based on physician and stage Offered Trial Accepted Participation Age < 65 51% 56% Age ≥ 65 34% 50% Age was: The only risk factor for if a patient was offered a clinical trial Not a predictor of whether a patient would agree to enroll in a trial Kemeny et al., JCO 2003 Barriers to Participation of Older Women with Breast Cancer in Clinical Trials Reasons Older Adults Eligible for Clinical Trials Were Not Offered Participation (N=33) % MD thought treatment was too toxic 33 Not the best treatment option available 27 MD unaware a trial was available 21 MD thought patient was not eligible 18 MD concerned with patient’s comorbid conditions 18 The patient is not the barrier. Kemeny et al., JCO 2003 Factors to Consider in Clinical Trial Design Incorporation of geriatric principles: Start low, go slow Include endpoints of relevance for older adults: Ability to live independently Impact of therapy on function or cognition Need for family caregiver Is biology of cancer different across the age spectrum? If so, separate trials are needed Can incorporation of geriatric principles in oncology trials help? Chronological Age ≠ Functional Age To weigh the risks and benefits Functional Age vs. Chronological Age The Extra Challenge: The Ultimately Efficient Clinic Vitals Taken Patient in Gown Sitting on Exam Table What is old? 65 Understanding the Grey Factors other than chronological age that predict morbidity & mortality in older adults Functional status Comorbid medical conditions Cognition Nutritional status Psychological state Social support Medications (polypharmacy) Geriatric Assessment Can Geriatric Assessment Predict Chemo Toxicity?
