The Impact of Intelligent Patient Management Model on Medication Adherence of Pyrotinib Compared to Traditional Patient Management Model: a Prospective, Multicenter, Randomized Controlled Clinical Study
- Conditions
- HER2 Positive Breast CancerPyrotinib Treatment
- Interventions
- Registration Number
- NCT06958627
- Brief Summary
This is a prospective, multicenter, randomized controlled clinical study to evaluate the effect of using intelligent patient management system on medication adherence of HER2 positive breast cancer patients receiving pyrotinib treatment. Pyrotinib is a small molecule tyrosine kinase inhibitor that can irreversibly inhibit HER1, HER2, and HER4.

- Primary Outcome Measures
Name Time Method medication adherence at 1-year 1-year medication adherence at 1-year is assessed using the tablet counting method and Eight-Item Morisky Medication Adherence Scale Evaluation Method 1: Tablet Counting Method
1. Definition/Formula:
Adherence percentage = (Actual tablets taken / Total tablets prescribed) \* 100% (Actual tablets taken = Total prescribed tablets - Remaining tablets - Lost tablets)
2. Procedure:
At the screening phase and Day 21 of each cycle, calculate the adherence percentage based on APP check-ins, and confirm the actual remaining tablets through follow-up.
Evaluation Method 2: MMAS-8 Scale
（1）Definition:
The Morisky Medication Adherence Scale-8 (MMAS-8) is a validated 8-item questionnaire. The total score ranges from 0 to 8, with higher scores indicating better adherence:
8: Good adherence 6-7: Moderate adherence \<6: Poor adherence （2）Procedure: Administer the MMAS-8 scale at the screening phase and Day 21 of each cycle. The total score is calculated as the sum of scores from the 8 questions.
- Secondary Outcome Measures
Name Time Method The time to deterioration (TTD) time from the date of randomization to the date of the first clinically significant deterioration through study completion, an average of 2 year TTD is defined as the time from randomization to confirmation of the first clinically significant deterioration (deterioration ≥ 10 points) in subsequent follow-up or death
Event-free survival (EFS) From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 3 years. EFS (defined as the time from randomization to the first documentation of progressing disease while on study therapy, postoperative disease recurrence, or death from any cause)
Overall survival (OS) From date of randomization until the date of death from any cause, assessed up to 4 years the time from randomisation to death from any cause
PRO From date of randomization until the date of death from any cause, assessed up to 4 years EORTC QLQ-C30 and NCC-BC-A1.0 questionnaire：
1. Outcome Measure 1 （1）Description: Scale Full Name: European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30).
Score Range:Global Health Status/QoL Scale: 0-100. Functional Scales (e.g., Physical, Role): 0-100. Symptom Scales (e.g., Fatigue): 0-100. （2）Interpretation: Higher scores on Global Health Status/QoL and Functional Scales indicate better outcomes.Higher scores on Symptom Scales indicate worse outcomes.
2. Outcome Measure 2 （1）Description: Scale Full Name: National Cancer Center Breast Cancer-Specific Patient-Reported Outcome Scale Version 1.0 (NCC-BC-A1.0).
Score Range:Total Score: 38-190 points (each item scored 1-5). （2）Interpretation:Higher total scores indicate poorer quality of life (for symptom-related items).Lower scores on positive function items (e.g., confidence, support) indicate worse outcomes.
3. Time Frame: Baseline, every 2 cycles, and at end of treatment.
