Presentation Transcript

  1. Target Product Claims in Cancer-Associated Fatigue

  2. Target Product Claims • Target product claims are a portion of the target product profile (TPP) approach to drug development • A TPP describes the profile of the drug similar to a package insert. • A Clinical Development Plan describes the program of studies to achieve/support the TPP

  3. TPP vs TPC • The TPP and TPC approach differs from hypothesis-based research. • The end result is described and the program is built around it. • The TPP/TPC is a “living” document and can be altered based on new data

  4. Claim List for Fatigue Therapy

  5. Fatigue Claims and Endpoints

  6. Questions for Discussion • How can we deal with the confounding sources of fatigue? • Depression/ mood disorder • Cancer treatment • Tumor • Surgery • Concomitant medication • Radiation

  7. Questions for Discussion • Are the symptoms of fatigue unidimensional or multidimensional? • If yes will there be subclaims for individual components? • If multidimensional – what would the impact be on claim language and fatigue measurement? • Claim for improvement in function • Claim for subjective improvement in cognitive aspects of fatigue • Claim for subjective improvement in mental aspects of fatigue (other than cognition)

  8. Questions for Discussion • What degree of improvement justifies the claim? MID? how to assess? • Is it feasible to prevent fatigue? • How can it be studied? • How do we limit the claim to cancer and not allow “claim creep” where chronic fatigue syndrome, liver disease etc may be treated without evidence?

  9. Advertisement ‘I’m on chemotherapy for my cancer. Some days, I am so tired I cannot get out of bed. I can’t think clearly, and I have no energy to do the things I love to do like working in my garden or play cards with my grandson. I asked my doctor if there way anything that could help me get over this awful tiredness. She told me that I was experiencing chemotherapy-induced fatigue, and that there was a new medication I could try that might help. After 5 weeks on XXX I can get up in the morning and not feel tired. I’m enjoying time with my grandkids (cut to picture of playing cards with young boy) and even back working in the garden (in garden with hat and gloves, kneeling as put weeds in bucket.

  10. Product Label Indication: XXX is indicated for treatment of chemotherapy-related fatigue in patients with XXX cancers Clinical studies: In three randomized, double-blind, placebo controlled clinical trials in breast, prostate, NSCLC, and CR cancer patients receiving various chemotherapy regimens post surgery, XXX plus standard of care was compared to standard of care alone. Patient-rated alertness, tiredness, and energy NRS were coprimary endpoints for all 3 trials found 3x more likely to have a 10% improvement in the cognitive, physical and emotional measures of chemotherapy-related fatigue for patients who received treatments containing XXX plus standard of care

  11. Clinical Trial Endpoint Concept Fatigue: cognitive Fatigue: physical Fatigue: emotional Measures Alertness NRS Tiredness NRS Motivation NRS (mental – anxiety/depression) Criteria Improvement of 10% of the possible range of the scale (i.e., >1 points on 11 point scale) OR Mean change from baseline with MID defined

  12. Study Design Issues • RCT required • Diagnosis of fatigue at baseline requires severity  2 on all 3 fatigue endpoints to enable range to improve by 2 points for meaningfulness criteria • Assumes we can demonstrate that a change of 2 points on the NRS is meaningful and reliably detectable on NRS for all three endpoints • Timing of fatigue assessment needs to show improvement while patients are still on chemotx to claim chemotx related fatigue. Issues: • how to select patients to ensure chemotx is the cause of fatigue. • how many different types of cancers, prior treatment histories etc would be required for a general chemotx fatigue claim
