Abstract:
The Canadian Cancer Clinical Trials Network (3CTN) was established in 2014 to address the decline in academic cancer clinical trials (ACCT) activity. Funding was provided to cancer centres to conduct a Portfolio of ACCTs. Larger centres received core funding and were paired with smaller centres to enable support and sharing of resources. All centres were eligible for incentive-based funding for recruitment above pre-3CTN baseline. Established performance measures were collected and tracked. The overall recruitment target was 50% above pre-3CTN baseline by Year 4. An analysis was completed to identify predictive success factors and descriptive statistics were used to summarize site characteristics and outcomes. From 2014-2018, a total of 11,275 patients were recruited to 559 Portfolio trials, an overall increase of 59.6% above pre-3CTN baseline was observed in Year 4. Twenty-five (51%) adult centres met the Year 4 recruitment target and the overall recruitment target was met within three years. Three factors that correlated with sites' achieving recruitment targets were: time period, region and number of baseline trials. 3CTN was successful in meeting its objectives and will continue to support ACCTs and member cancer centres, monitor performance over time and seek continued funding to ensure success, better trial access and outcomes for patients.
Insights
The Canadian Cancer Clinical Trials Network (3CTN) successfully boosted academic cancer clinical trials (ACCT) recruitment by 59.6% within four years. This initiative met its goals, enhancing patient access to vital cancer research and improving outcomes.
Area of Science:
- Oncology
- Clinical Research
- Health Services Research
Background:
- Academic cancer clinical trials (ACCT) activity faced a decline.
- The Canadian Cancer Clinical Trials Network (3CTN) was established in 2014 to address this issue.
- Funding models were implemented to support ACCTs across Canadian cancer centers.
Purpose of the Study:
- To evaluate the effectiveness of the 3CTN in increasing ACCT activity.
- To identify factors predicting successful patient recruitment in ACCTs.
- To assess the impact of the 3CTN on cancer trial access and patient outcomes.
Main Methods:
- A portfolio approach to funding cancer centers for ACCTs.
- Implementation of core and incentive-based funding structures.
- Tracking of established performance measures, including patient recruitment.
- Statistical analysis to identify success factors for recruitment targets.
Main Results:
- From 2014-2018, 11,275 patients were recruited to 559 trials.
- Overall recruitment increased by 59.6% above the pre-3CTN baseline by Year 4.
- The overall recruitment target was achieved within three years, with 51% of adult centers meeting the Year 4 target.
- Time period, region, and number of baseline trials were identified as key factors for achieving recruitment targets.
Conclusions:
- The 3CTN successfully met its objectives for increasing ACCT activity.
- The network demonstrated a significant positive impact on patient recruitment and trial access.
- Continued support and funding are recommended to sustain and enhance ACCTs for improved patient outcomes.
