TRTRM (ACTTOP) -Guided Dosing Strategy in Older Patients With Cancer
Hong Kong400 participantsStarted 2026-05-04
Plain-language summary
Older adults receiving systemic cancer treatments are at increased risk of developing severe treatment-related toxicities (TRT). Existing prediction tools such as CARG and CRASH have limited applicability in Chinese populations and do not fully address toxicities associated with newer therapies, including immunotherapy and targeted agents. The Treatment-related Toxicity Risk Model (TRTRM) was recently developed and validated in Hong Kong using data from 700 older cancer patients and has demonstrated better predictive accuracy and clinical relevance compared with existing tools.
This multi-center, open-label, randomized controlled trial aims to evaluate the clinical utility of the TRTRM by guiding treatment dose intensity and monitoring strategies. Participants aged 65 years or older who are starting a new systemic anti-cancer treatment will be randomized in a 1:1 ratio to receive either usual care or TRTRM-informed care. In the intervention arm, patients identified as having intermediate or high risk of toxicity will receive a "start-low, go-slow" dosing strategy with close monitoring, while low-risk patients will receive standard dosing.
The primary outcome is the incidence of grade 3 or higher treatment-related toxicities within the first two months of treatment initiation. Secondary outcomes include emergency visits, unplanned hospitalizations, premature treatment termination, early mortality, quality of life, and overall survival.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
