Toward a Comprehensive Supportive Care Intervention for Older or Frail Men With mCRPC

Official Title

Toward a Comprehensive Supportive Care Intervention for Older or Frail Men With mCRPC


1. Multicentre pilot study (n=90) which aims to study a prevalent population of elderly or frail patients with mCRPC whom are often excluded from clinical trial participation. (Data is sorely needed in this population) 2. The study aims to determine: 1. if symptom monitoring (daily) is feasible using telephone or electronic means of communications in the elderly or frail patient with mCRPC 2. The time course/pattern of symptoms important to quality of life for patients undergoing chemotherapy, abi/enza, or Radium 223 3. If changes in physical activity (quantified by fitbit) predict for changes to ESAS in men undergoing treatment d) Qualitatively assess the supportive care needs of older/frail men with mCRPC

Trial Description

Primary Outcome:

  • Daily monitoring with Edmonton Symptom Assessment Scale (ESAS)
  • Using a personal physical activity tracker step counts are monitored daily.
  • Brief Pain Inventory-Short Form (BPI-SF) to measure pain severity
  • Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF) to measure fatigue
  • Insomnia Severity Index (ISI) to measure treatment related insomnia
  • Patient Health Questionnaire 9-item (PHQ-9) to measure treatment related depression
  • Generalized Anxiety Disorder 7-item (GAD) to measure treatment related anxiety
Secondary Outcome:
  • Participants symptom experience by Qualitative interview
  • Study Completion Questionnaire to measure participant burden and satisfaction
Study Aim: The previous multi-centre observational study (TOPCOP), funded by Prostate Cancer Canada, demonstrated important declines in multiple areas of quality of life, and fatigue and functional decline which were common issues that often limited further treatment. Emerging data from other settings demonstrate that (a) close monitoring of symptoms may reduce treatment toxicity and improve survival; (b) improving physical activity and targeting pain and sleep may improve fatigue and function. Whether these are feasible in the setting of older or frail men with mCRPC is unclear. Incorporating what the investigators have learned from TOPCOP and emerging supportive oncology literature, our main aim is to examine the emergence of key symptoms (fatigue, pain, insomnia) and explore whether reductions in daily physical activity are early indicators of toxicity over one treatment cycle (3-4 weeks) and therefore targetable in a subsequent intervention study.

Study Design: This is a prospective multicentre observational study. The investigators will enroll English-speaking men with mCRPC who are either age 75 or older or age 60-74 and frail using (a) chemotherapy; (b) abiraterone or enzalutamide; (c) Radium.

Daily telephone-based brief symptom screening will be done with the Edmonton Symptom Assessment Scale (ESAS). Daily monitoring of physical activity (step counts) will be done with commercial smartphone apps or a Fitbit device. Moderate or higher symptoms (>3/10) on ESAS or a decrease in daily step count of 15% or more triggers more detailed telephone-based toxicity assessment and measures of pain, sleep, and fatigue as appropriate. The study duration is 3 weeks (1 cycle of chemotherapy) or 4 weeks (abiraterone/enzalutamide/radium). Qualitative interviews will be done to explore challenges with treatment tolerability and adherence.
