Project description:Hedgehog inhibitors are promising alternative treatments for patients with advanced basal cell carcinomas. Sonidegib (Odomzo®), an oral smoothened (SMO) antagonist, is indicated for the treatment of adult patients with locally advanced basal cell carcinoma (laBCC) who present recurrence following surgery or radiation therapy, or those who are not candidates for surgery or radiotherapy. Several studies and randomized controlled trials have been conducted to evaluate the efficacy, safety, and tolerability of this new molecule that has demonstrated a good response rate (44%). Grade 1-2 adverse events have also been reported. Further studies of real-world experiences are needed to better understand the correct management of the drug, alternative dosing regimens, and differences with other hedgehog inhibitors. This article provides a complete overview of the pharmacology and pharmacokinetics of sonidegib and a report of the trials and studies conducted. The most frequent adverse events and their correct management are also discussed.

Project description:Basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer. If left untreated, BCCs can become locally aggressive or even metastasize. Currently available treatments include local destruction, surgery, and radiation. Systemic options for advanced disease are limited. The Hedgehog (Hh) pathway is aberrantly activated in a majority of BCCs and in other cancers. Hh pathway inhibitors are targeted agents that inhibit the aberrant activation of the Hh pathway, with smoothened being a targeted component. Sonidegib is a novel smoothened inhibitor that was recently approved by the US Food and Drug Administration. This review focuses on BCC pathogenesis and the clinical efficacy of sonidegib for the treatment of advanced BCC.

Project description:Background: Positron emission tomography/computed tomography (PET/CT) with 18F-fluorodeoxyglucose (18F-FDG) is a firmly established tool in oncology and is gaining importance in dermato-oncology. However, its use in advanced basal cell carcinoma (BCC) is limited, with only a few case reports and a single study focused on vismodegib. This study evaluates the role of 18F-FDG PET/CT in advanced BCC treated with sonidegib. Methods: We retrospectively assessed the clinical data of patients with advanced BCC who underwent 18F-FDG PET/CT between January 2022 and January 2024. Inclusion criteria included histologically confirmed BCC, FDG-avid lesions on baseline PET/CT, and a minimum follow-up of 6 months. Metabolic response was assessed using the PET Response Criteria in Solid Tumors (PERCIST). Results: Four patients with advanced BCC treated with sonidegib were included, presenting with a total of 10 hypermetabolic lesions at baseline PET/CT. The mean interval between baseline and follow-up scans was 8.7 ± 1.6 months. According to PERCIST, two patients achieved a complete metabolic response (CMR), while the other two had stable metabolic disease (SMD). Low baseline-standardized uptake values (i.e., SUVmax, SUVmean) and reduced total lesion glycolysis (TLG) were associated with CMR. No relapses were observed during follow-up. Conclusions: This study suggests that 18F-FDG PET/CT may help identify advanced BCC patients who are likely to benefit from sonidegib treatment. Further research is needed to fully explore the potential of PET/CT in this specific clinical context.

Project description:The pivotal BOLT (Basal cell carcinoma Outcomes with LDE225 [sonidegib] Treatment) study established the durable efficacy and manageable toxicity of sonidegib 200 mg once daily (QD) through 42 months in patients with advanced basal cell carcinoma (BCC). This secondary analysis used expression of Glioma-associated oncogene homolog 1 (GLI1) as a biomarker to assess the extent of Hedgehog pathway inhibition by sonidegib in patients with locally advanced BCC (laBCC) and metastatic BCC (mBCC). The study enrolled 230 patients, 79 and 151 receiving sonidegib 200 and 800 mg QD, respectively. At week 17, GLI1 expression was reduced from baseline by a median percentage (95% confidence interval) of 88.7% (54.6%-93.0%) and 97.0% (77.5%-98.9%) for aggressive laBCC, 97.5% (80.3%-98.8%) and 95.0% (80.7%-97.5%) for nonaggressive laBCC, and 99.1% (96.4%-99.6%) and 99.3% (95.9%-99.9%) for mBCC in the 200 and 800 mg groups, respectively. Substantial repression of GLI1 was observed in patient subgroups stratified by age, sex, BCC cytological subtype, Eastern Cooperative Oncology Group performance status, lesion site, baseline number of BCCs, and prior radiotherapy. Results support further studies on the inhibition of Hedgehog pathway genes by sonidegib in patients with laBCC and mBCC.

Project description:PurposeTo assess the tumor response to the smoothened (SMO) inhibitor, sonidegib (LDE225), in patients with an advanced basal cell carcinoma (BCC) resistant to treatment with vismodegib (GDC0449).Experimental designNine patients with an advanced BCC that was previously resistant to treatment with vismodegib were given sonidegib in this investigational, open-label study. Tumor response was determined using the response evaluation criteria in solid tumors. SMO mutations were identified using biopsy samples from the target BCC location.ResultsThe median duration of treatment with sonidegib was 6 weeks (range, 3-58 weeks). Five patients experienced progressive disease with sonidegib. Three patients experienced stable disease and discontinued sonidegib either due to adverse events (n = 1) or due to election for surgery (n = 2). The response of one patient was not evaluable. SMO mutations with in vitro data suggesting resistance to Hh pathway inhibition were identified in 5 patients, and none of these patients experienced responses while on sonidegib.ConclusionsPatients with advanced BCCs that were previously resistant to treatment with vismodegib similarly demonstrated treatment resistance with sonidegib. Patients who have developed treatment resistance to an SMO inhibitor may continue to experience tumor progression in response to other SMO inhibitors.

Project description:IntroductionBasosquamous carcinoma is an uncommon subtype of basal cell carcinoma (BCC), characterized by aggressive local growth and metastatic potential, that mainly develops on the nose, perinasal area, and ears, representing 1.2-2.7% of all head-neck keratinocyte carcinomas. Although systemic therapy with hedgehog inhibitors (HHIs) represents the first-line medical treatment in advanced BCC, to date, no standard therapy for advanced basosquamous carcinoma has been established. Herein, we reported a case series of patients affected by locally advanced basosquamous carcinomas, who were treated with HHIs.Case presentationData of 5 patients receiving HHIs for locally advanced basosquamous carcinomas were retrieved (2 women and 3 males, age range: 63-89 years, average age of 77 years). Skin lesions were located on the head-neck area; in particular, 4 tumors involved orbital and periorbital area and 1 tumor developed in the retro-auricular region. A clinical response was obtained in 3 out of 5 patients (2 partial responses and 1 complete response), while disease progression was observed in the remaining 2 patients. Hence, therapy was interrupted, switching to surgery or immunotherapy.ConclusionIncreasing evidence suggests considering HHIs for large skin tumors developing in functionally and cosmetically sensitive areas, in patients with multiple comorbidities, although their use for basosquamous carcinoma require more exploration, large cohort populations, and long follow-up assessment.

Project description:IntroductionSonidegib is approved to treat locally advanced basal cell carcinoma (laBCC) in the USA, EU, Switzerland, and Australia and metastatic basal cell carcinoma (mBCC) in Switzerland and Australia in patients not amenable to surgery or radiotherapy. Vismodegib is approved to treat patients with mBCC, recurrent laBCC, or those not candidates for surgery or radiation. There is no head-to-head trial comparing Hedgehog inhibitors. We describe time to onset and severity of adverse events (AEs) in two studies reporting cumulative AE incidence every treatment cycle: the sonidegib phase 2 BOLT study and the expanded-access, open-label vismodegib study.MethodsThis analysis included patients with histologically confirmed laBCC or mBCC from BOLT who received sonidegib 200 mg once daily (QD) and patients from the vismodegib study who received vismodegib 150 mg QD. Cumulative occurrence of AEs and median time to AE onset were calculated on 30-day cycles for sonidegib and 28-day cycles for vismodegib. AEs were graded for severity using the Common Terminology Criteria for Adverse Events. Only common (at least 15% incidence) AEs were analyzed in this study.ResultsOver 18 treatment cycles, the most common all-grade AEs for sonidegib and vismodegib were muscle spasm (54.4% vs 70.6%; P = 0.0236), alopecia (49.4% vs 58.0%; no significant difference [NS]), and dysgeusia (43.0% vs 70.6%; P = 0.0003); incidences of diarrhea, nausea, fatigue, and weight decrease were 31.6% vs 25.2% (NS), 39.2% vs 19.3% (P = 0.0032), 32.9% vs 19.3% (P = 0.0429), and 30.4% vs 16.0% (P = 0.0217), respectively. Sonidegib-treated patients had more delayed median time to onset for all AEs than vismodegib-treated patients, except fatigue and weight decrease (NS). Most AEs reported were grade ≤ 2.ConclusionThis post hoc analysis suggests lower overall incidence and slower onset of certain AEs in patients treated with sonidegib compared with vismodegib. In the absence of head-to-head comparisons, the relevance of these findings needs further studies to provide conclusive evidence.

Project description:IntroductionSonidegib is a Hedgehog pathway inhibitor approved to treat locally advanced basal cell carcinoma and, depending on regulatory approval, metastatic basal cell carcinoma. Results from the BOLT study demonstrated robust efficacy and continued tolerability through 42 months. This analysis evaluated the impact of sonidegib dose reductions and interruptions in patients with advanced basal cell carcinoma through 42 months.MethodsBOLT was a randomized, double-blind, multicenter, phase 2 study. Adults with no previous Hedgehog pathway inhibitor therapy were randomized 1:2 to sonidegib 200 or 800 mg once daily. Primary endpoint was objective response rate. Dose modifications were permitted in patients unable to tolerate the dosing schedule or if a treatment-related adverse event was suspected.ResultsThe incidence of dose interruptions was similar between the 200- and 800-mg groups (68.4% vs 65.3%, respectively). Dose reductions occurred more frequently in patients receiving sonidegib 800 mg (36.7%) than 200 mg (16.5%). Overall response rate for all patients receiving sonidegib 200 mg daily was 48.1% and was similar to those of patients without dose reduction or interruption (48.5%) and patients with at least one dose reduction or interruption (46.2%).ConclusionDose reductions and interruptions were practical and did not impact the efficacy of sonidegib. In patients with advanced basal cell carcinoma who necessitate long-term treatment, dose interruptions may be beneficial for continued treatment and disease control.Trial registrationClinicalTrials.gov identifier, NCT01327053.
