Metastatic Breast Cancer: Recruitment Rates and Trials Performance Statistics

In our last article, we discussed the past experience and competition of metastatic breast cancer clinical trials worldwide. There is a tradition in conducting of metastatic breast cancer clinical trials. 

As of today, there are 931 completed or expanded access clinical trials. In this article, we will analyze their performance in regards to their average recruitment rate. 

Here’s the TrialHub map comparing countries based on their average recruitment rates (ARR) focusing only on metastatic breast cancer clinical trials:

As you can see the ARR varies between 0,07 and 1,08 patients/site/month. This is taking into account all trials being done so far. If we are to limit ourselves for the last 3 years, here’s how the landscape would look like:

The clinical trial targeting women with metastatic breast cancer with the highest recruitment rate is a trial conducted by the University of Alabama at Birmingham (USA). 

The trial was observational and needed 100 patients with metastatic breast cancer to gain knowledge about out-of-pocket (OOP) expenses and lost opportunity costs.

The top-performing trial focused on treatment in the last 3 years was an open-label, single-arm, multi-center, Phase II study. The study aimed to determine the activity of nab-paclitaxel plus lapatinib in the first and second-line setting in women with ErbB2 overexpressing MBC. 

The study was sponsored by Novartis and was looking to recruit 60 patients. Its recruitment rate was 138,46 and it was performed only in the USA.
