TRUE-PTX Comparative Analysis
TRUE-PTX is a comprehensive study comparing Paclitaxel Drug-Eluting and bare device treatment for Peripheral Artery Disease (PAD) using real-world data*. This analysis, which includes over 10,000 patients in the United States, examines 12-month amputation and readmission rates.
This large-scale, near-real-time clinical evidence leveraging Truveta aggregated electronic health record (EHR) data shows that PAD treatment with paclitaxel drug-eluting devices may reduce the risk of amputation and readmission vs. treatment with non-drug devices, potentially reducing associated healthcare costs.
TRUE-PTX
Treatment with a non-DE device increases odds for any amputation by
30%
Treatment with a non-DE device increases odds for readmission3 by
15%
TRUE-PTX Eluvia
Compared to Eluvia, non-DE devices increased amputation odds by
47%
Compared to Eluvia, non-DE devices increased readmission odds by
23%
TRUE-PTX Study Design and Population
The objective was to compare outcomes in patients with Peripheral Artery Disease (PAD) treated with Paclitaxel Drug-Eluting devices (DCB, DES) versus those treated with non-DE devices (BMS, PTA). The study design involved a comparative propensity score-matched analysis of de-identified electronic health record (EHR) data.
Patients with PAD undergoing endovascular femoropopliteal balloon or stent therapy (± paclitaxel)
N = 10,474
Data source was Truveta, which aggregates normalized EHR data from more than 120 million de-identified patient records across more than 30 U.S. health systems.
In a second pase, TRUE-PTX Eluvia sub group was developed to compare outcomes for patients from the drug-eluting devices who we retreated exclusively with Eluvia to patients who received treatment without a drug coating; this could be a stent or balloon,
TRUE-PTX Comparative Analysis2 Results
Outcomes before propensity score matching
12-month amputations and readmissions occurred significantly less frequently for patients treated with a DE device and with Eluvia specifically
- TRUE-PTX
- TRUE-PTX Eluvia
| DE | Non-DE | P-value | |
| Any Limb Amputation | 7.5% | 8.9% | 0.01 |
| Same Limb Amputation | 1.5% | 2.3% | 0.003 |
| Any Readmission | 53.8% | 57.8% | <0.001 |
Mortality**

| N | 5298 | 5145 | |

| Event rate | 23.4% | 21.7% | 0.296 |
Outcomes after propensity score matching
Patients treated with non-DE devices were more likely to have any amputation, any readmission and readmission associated with a DE or non-DE procedure
TRUE-PTX
Treatment with a non-DE device increases odds for any amputation by
30%
Treatment with a non-DE device increases odds for readmission3 by
15%
TRUE-PTX Eluvia
Compared to Eluvia, non-DE devices increased amputation odds by
47%
Compared to Eluvia, non-DE devices increased readmission odds by
23%
In propensity score-matched patients, above-ankle amputation and any readmission occurred significantly less frequently with Eluvia DES vs non-DE therapy, within 12 months
Results of the TRUE-PTX analysis support use of paclitaxel DE devices, and Eluvia DES specifically, to reduce readmissions and amputations compared with non-DE devices, saving limbs and reducing healthcare costs.
