Abstract 33P

Background

Peripheral edema (PE), a class effect of MET TKIs, can impact treatment (tx) adherence. We conducted the Powerhouse Insights from Virtual Oncology Therapeutic Specialists (PIVOTS) survey of physicians’ experience with MET TKIs to better understand associated PE and optimize its management.

Methods

An online survey assessed onset, time to resolution, symptoms, prevention, and management of PE during tx with four available MET TKIs for MET exon 14 skipping NSCLC (tepotinib, capmatinib, savolitinib and crizotinib).

Results

In total, 26 physicians participated: Asia (14), Europe (6), UK (2) and North America (4). 24 physicians had experience with tepotinib, 10 with savolitinib, 20 each with capmatinib and crizotinib, and 7 with all four MET TKIs. Six physicians had experience with >20 patients (pts), 9 with 10–20 pts, 6 with 5–10 pts and 5 with <5 pts treated with a MET-TKI. 77% of physicians reported that >50% of pts had PE with MET TKIs. Low mobility, age, and time on tx were reported as common risk factors, and cardiac disease as the most common comorbidity. PE onset, which may take >6 months, and time to improvement was considered similar among MET-specific TKIs, with crizotinib (a multi-kinase TKI) resulting in less frequent, less severe, and less durable PE. Swollen extremities were reported by 96% of physicians as the most bothersome symptom followed by pain (46%) and weight gain (31%), with a resolution time of up to 3 months in mild-moderate PE and up to 6 months in severe PE. Pain (81% vs 23%) and skin lesions (50% vs 23%) were reported as more common in severe vs mild-moderate PE, respectively. 62% of physicians incorporated multiple preventive measures simultaneously (bed/feet elevation [88%], compression stockings [69%], massage [63%], salt intake reduction [50%], exercise/diuretics [25%]); only 13% incorporated at tx initiation. The most common tx were diuretics (89%), non-pharmacologic measures (85%), MET TKI interruption (73%) and dose reduction (65%); 4/5 Chinese physicians reported consulting vascular specialists.

Conclusions

The PIVOTS survey indicates the most important unmet needs for PE management are developing effective tx, incorporating preventive measures at MET TKI initiation (not only at PE onset), and clarity of its mechanism of action associated with MET TKI.
