Imageable Radioembolization Microspheres for Treatment of Unresectable Hepatocellular Carcinoma: Interim Results from a First-in-Human Trial.

PURPOSE: To determine 6-month interim safety, effectiveness, and multimodal imageability of imageable glass microsphere yttrium-90 (90Y) radioembolization for unresectable hepatocellular carcinoma (HCC) in a first-in-human trial. MATERIALS AND METHODS: Imageable microspheres (Eye90 Microspheres; ABK Biomedical, Halifax, Nova Scotia, Canada), a U.S. Food and Drug Administration (FDA) Breakthrough-Designated Device consisting of glass radiopaque 90Y microspheres visible on computed tomography (CT) and single photon emission CT (SPECT), were used to treat 6 subjects with unresectable HCC. Patients underwent selective (≤2 segments) treatment in a prospective open-label pilot trial. Key inclusion criteria included liver-only HCC, performance status ≤1, total lesion diameter ≤9 cm, and Child-Pugh A status. Prospective partition dosimetry was utilized. Safety (measured by Common Terminology Criteria for Adverse Events [CTCAE] v5), multimodal imageability on CT and SPECT, and 3- and 6-month imaging response by modified Response Evaluation Criteria in Solid Tumors on magnetic resonance (MR) imaging were evaluated. RESULTS: Seven tumors in 6 subjects were treated and followed to 180 days. Administration success was 100%. Microsphere distribution measured by radiopacity on CT correlated with SPECT. Ninety-day target lesion complete response (CR) was observed in 3 of 6 subjects (50%) and partial response (PR) in 2 (33.3%). At 180 days, target lesion CR was maintained in 3 subjects (50%) and PR in 1 (16.7%). Two subjects could not be reassessed, having undergone intervening chemoembolization. All subjects reported adverse events (AEs), and 5 reported AEs related to treatment. There were no treatment-related Grade ≥3 AEs. CONCLUSIONS: Radioembolization using imageable microspheres was safe and effective in 6 subjects with unresectable HCC at 6-month interim analysis. Microsphere distribution by radiopacity on CT correlated with radioactivity distribution by SPECT, providing previously unavailable CT-based tumor targeting information.

Efficacy and Safety of Naftifine HCl Cream 2% in the Treatment of Pediatric Subjects With Tinea Corporis.

BACKGROUND: Tinea corporis is fungal infection of body surfaces other than the feet, groin, scalp, or beard. Naftifine hydrochloride is a topical antifungal of the allylamine class used to treat tinea corporis, displaying fungicidal activity and clinically significant anti-bacterial and anti-inflammatory effects.
OBJECTIVE: To evaluate the efficacy and safety of two-weeks once daily application of naftifine cream 2% in the treatment of tinea corporis among pediatric subjects.
METHODS: At baseline, 231 subjects were randomly assigned 1:1 to naftifine cream 2% (n=116) and vehicle (n=115). Treatment effect consisting of mycologic determination (KOH and dermatophyte cultures) and scoring of clinical symptom severity was evaluated at baseline, week 2 (end of treatment) and week 3. Efficacy was analyzed in 181 subjects (n=88, naftifine; n=93, vehicle) with a positive baseline dermatophyte culture and KOH for whom week 3 assessments were available. Safety was evaluated by adverse events (AE) and laboratory values in 231 subjects (n=116, naftifine; n=115, vehicle).
RESULTS: Children with tinea corporis treated with naftifine cream 2% demonstrated significantly greater improvements from baseline over vehicle for mycological cure (P<0.0001) and treatment effectiveness (P=0.003) as early as 2 weeks (end of treatment). Response rates continued to increase post-treatment and were the highest 1-week after completion of the therapy (P=0.003 for complete cure; and P<0.001 for mycological cure and treatment effectiveness). Treatment related adverse events were minimal.
CONCLUSIONS: Treatment with naftifine cream 2% applied once daily for two weeks was well-tolerated and was effective in treating tinea corporis in children. Further improvement was observed 1-week after treatment completion for all key outcome measures (complete cure, mycological cure, treatment effectiveness, clinical cure, and clinical success) and clinical signs and symptoms (erythema, induration, and pruritus).
