Trends in cell therapy clinical trials 2011 – 2013

Since last year, I’m sharing some trends in cell therapy clinical trials. Real time tracking of all registered trials allows to identify trends in multiple dimensions. Today I”m posting a snapshot of trending for the last 3 years – from 2011 to 2013. There could be some minimal discrepancies in numbers between this and previous reports (due to accidental detection of trials which were not captured initially). Please refer to this report as the latest update.

Total number of trials
Total number of cell therapy trials, registered in international databases, continue to increase. From 2011 to 2013 a total number of trials increase about 2 times.

The value of US NCT database (ClinicalTrials.gov) remains constant over the years, representing 74% of all registered cell therapy trials internationally.

Sponsorship
The number on industry-sponsored clinical trials significantly increased in 2013, compared to previous two years. In the same time, the number of academic trials continue to grow even more rapidly.

Demographics
As in the previous 2 years, US and China dominated all other countries in number of cell therapy trials in 2013. However, the US trend is positive, but China’s trend is negative. Interestingly, Japan made a biggest jump up in 2013. South Korea, UK and Iran stay pretty much flat over last 3 years.

This graph shows a value of the most representative countries in % of total trials number.

If we look at regions in general, we will not able to see significant fluctuations in the last few years. I’d only notice a shrinkage of Europe in 2013.

Cell types
In order to demonstrate some interesting trends I’ve picked the most frequently used cell types in clinical trials. Mesenchymal stromal cells (MSC) trials continue to surpass all other cell types. In 2013, T-cell trials continued to grow slowly and represented the second most frequent cell type after MSC. The mostly rapidly growing cell types were bone marrow mononuclear cells (BM MNC) and dendritic cells (DC). DC were the “biggest movers” in 2013. Interest to hematopoietic stem/ progenitor cells (including mobilized blood, cord blood and bone marrow) dropped significantly in 2013. NK cells and adipose stromal vascular fraction (SVF) went up in 2013. Embryonic stem cell trials plunged to zero.

Indications
Malignancies is the most frequent indication for cell therapy trials. It skyrocketed in the last 3 years (increase about twice every year)! Of course, it coupled with interest to cellular immunotherapy and strictly correlates with use of immune cells (T-cells, DC, NK cells…). Interest to cell therapy in neurology, cardiovascular medicine and ophthalmology remains pretty much flat. Muskoloskeletal diseases have a prominent positive trend. Interest to cell therapy for liver diseases seem to be decreasing.

It was a snapshot of dataset analysis for the last 3 years. I’ve picked only some trends to demonstrate that the data could be “sliced and diced” in many different ways.
