Association Between Drug-related Cutaneous Adverse Events and Progression Free Survival in Patients Treated with Enfortumab Vedotin

Completed
Conditions
Cutaneous Adverse
Registration Number
NCT06682845
Lead Sponsor
Hospices Civils de Lyon
Brief Summary

Enfortumab vedotin (EV) is an antibody-drug conjugate (ADC) targeting nectin-4. In patients with metastatic urothelial carcinoma, EV in combination with pembrolizumab (anti-PD1) provides significantly better progression-free and global survival than platinum-based chemotherapies, with the benefit observed from the first line of treatment. However, EV is associated with a high frequency of cutaneous adverse events (AE), which may be due to physiological Nectin-4 expression in keratinocytes. These cutaneous toxicities include bullous/blistering toxicities and toxic epidermal necrolysis-like AE. While the association between cutaneous AE and survival has been demonstrated with anti-PD1, its association with survival in patient treated with ADC remains unknown. The objective of this retrospective dual-centric study is to determine whether there is an association between drug-related cutaneous AE and progression free survival in patients treated with EV.

Primary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS) according to the occurrence of cutaneous adverse events (AE)From the start of EV treatment until disease progression or death, with data collected from 01/01/2015 to 02/05/2024.

Progression-Free Survival (PFS) is defined as the time from the start of EV treatment to the occurrence of disease progression or death from any cause, whichever occurs first. This measure will assess the impact of any grade cutaneous adverse events (AEs) on PFS.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS) according to the occurrence of cutaneous adverse events (AE)From the start of EV treatment until death from any cause, with data collected from 01/01/2015 to 02/05/2024.

Overall Survival (OS) is defined as the time from the start of EV treatment to death from any cause. This measure will assess the impact of any grade cutaneous adverse events (AEs) on OS.

PFS/OS according to blistering toxicityFrom the start of EV treatment until disease progression, death, or first occurrence of blistering toxicity, with data collected from 01/01/2015 to 02/05/2024.

This measure will assess PFS and OS in relation to the occurrence of blistering toxicity. Blistering toxicity is defined as a dermatosis with vesicular, bullous, and/or exfoliative lesions.

PFS/OS according to cutaneous AE in patients co-treated with anti-PD1From the start of combined EV and anti-PD1 treatment until disease progression or death, with data collected from 01/01/2015 to 02/05/2024.

This measure will assess PFS and OS in relation to the occurrence of cutaneous adverse events in patients who are also receiving anti-PD1 treatment.

Identification of predictive risk factors for cutaneous AERetrospective analysis of data from the treatment initiation until the last recorded follow-up, with data collected from 01/01/2015 to 02/05/2024.

Identification of potential predictive risk factors associated with the occurrence of cutaneous adverse events (defined as any grade skin rash, excluding isolated pruritus).
