8 Use in Specific Populations

8.4 Pediatric Use

Additions and/or revisions underlined

The safety and effectiveness of Lymphoseek have been established in pediatric patients 1 month of age and older. Use of Lymphoseek for this population is supported by evidence from adequate and well- controlled studies in adults with additional safety and diagnostic data from an open-label, single-arm trial in 23 pediatric patients with either melanoma (5), rhabdomyosarcoma (4), or other solid tumors (14) who received Lymphoseek (18.5 MBq and 50 mcg) and underwent intraoperative lymphatic mapping, with or without additional use of preoperative scintigraphic imaging and/or blue dye [see Clinical Studies (14.1)].

Review of the clinical data, including evaluation of the frequency of adverse reactions and localization of lymph nodes, has not identified differences in safety or efficacy between pediatric patients and older patients.

8.5 Geriatric Use

Additions underlined

Of the 553 adult patients enrolled in clinical studies of breast cancer, melanoma, and squamous cell carcinoma (SCC) of oral cavity, skin, and lip, 179 (32%) were aged 65 or older. Review of the clinical data, including evaluation of the frequency of adverse reactions, has not identified differences in safety or efficacy between elderly patients (65 to 90 years of age) and younger adult patients (18 to 65 years of age).
