BACKGROUND: The Hedgehog (Hh) pathway is upregulated in cervical cancer and associated with poor outcome. We explored the effects of Hh pathway inhibition in combination with RTCT in a patient derived orthotopic cervical cancer xenograft model (OCICx). METHODS: 5E1, a monoclonal antibody for SHH, or Sonidegib (LDE225), a clinical SMO inhibitor (Novartis) were added to RTCT. We investigated tumour growth delay, metastasis and GI toxicity using orthotopic cervical cancer xenografts models...

The Hedgehog (Hh) signaling pathway is associated with diverse aspects of cellular events, such as cell migration, proliferation, and differentiation throughout embryonic development and tissue patterning. An abnormal Hh signaling pathway is linked to numerous human cancers, including basal cell carcinoma (BCC), medulloblastoma (MB), lung cancer, prostate cancer, and ovarian cancer, and it is therefore a promising target in cancer therapy. Using a structure-hopping approach, we designed new Hh signaling pathway inhibitors with isoindolinone or quinazolinone moieties, which were synthesized and biologically evaluated using an 8xGli-luciferase (Gli-Luc) reporter assay in NIH3T3 cells...

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...

PURPOSE: Sonidegib prevents activation of the Hedgehog signal transduction pathway. This PK-QT analysis has been performed to test for potential prolongation of the QT/QTc interval during extended use, and to understand the exposure-QT relationship for sonidegib in patients and in healthy volunteers (HV). METHODS: A pooled analysis of the change in QT interval corrected for heart rate according to Fridericia's formula was conducted across four patient studies from a total of 341 patients (n = 211, 102, 21, and 7 from the phase II pivotal study A2201, study X2101, study X1101, and study B2209, respectively), and across four healthy volunteer studies from a total of 204 healthy volunteers (n = 146, 36, 16, and 6 from study A2114, study A1102, study A2108, and study A2110, respectively)...

INTRODUCTION: Basal cell carcinomas (BCCs) are the commonest malignancy in the Western world. Locally advanced BCCs (laBCCs) represent tumours that have developed in difficult-to-treat facial sites, aggressively recurrent tumours, large neglected tumours and those in which current treatment options are excluded by clinical or patient-driven criteria. It is estimated laBCCs represent 1% of BCCs. AREAS COVERED: Sonidegib is an oral hedgehog pathway inhibitor with a novel structure...

OBJECTIVES: The Hedgehog pathway has been implicated in small cell lung cancer (SCLC) tumor initiation and progression. Pharmacologic blockade of the key Hedgehog regulator, Smoothened, may inhibit these processes. We performed a phase I study to determine the maximum tolerated dose (MTD) of sonidegib (LDE225), a selective, oral Smoothened antagonist, in combination with etoposide/cisplatin in newly diagnosed patients with extensive stage SCLC. MATERIALS AND METHODS: Patients received 4-6 21-day cycles of etoposide/cisplatin with daily sonidegib...

INTRODUCTION: Advanced and metastatic basal cell carcinomas (BCCs) are rare but still present a severe medical problem. These tumors are often disfiguring and impact the quality of life by pain or bleeding. Based on discovery of the hedgehog (Hh) signaling pathway and its role in the pathogenesis of BCCs, smoothened (SMO) inhibitors have been developed with Sonidegib being the 2nd in class. It is the only Hh pathway inhibitor investigated in a randomized trial accompanied by pharmacodynamic investigations...

: : Abnormal activation of hedgehog pathway signaling is a key driver in the pathogenesis of basal cell carcinoma (BCC). Vismodegib, a first-in-class small-molecule inhibitor of hedgehog pathway signaling, is approved by regulatory authorities for the treatment of adults who have metastatic BCC or locally advanced BCC that has recurred after surgery, or who are not candidates for surgery and who are not candidates for radiation. A second inhibitor, sonidegib, was also recently approved for the same patient group with locally advanced BCC...

Basal cell carcinoma (BCC), although mostly locally confined, is the most common cancer. Most BCCs harbor inactivating mutations in the membrane receptor/gene Ptch, thereby activating the Hedgehog signaling pathway (Hh) via the essential signaling molecule Smoothened (SMO). Novel small-molecule inhibitors or antagonists of SMO have shown excellent response rates in patients with locally advanced, unresectable and metastatic BCC in roughly 35-60% of patients, with disease control rates and clinical benefit being even higher...

Targeting the Hedgehog (Hh) pathway represents a potential leukaemia stem cell (LSC)-directed therapy which may compliment tyrosine kinase inhibitors (TKIs) to eradicate LSC in chronic phase (CP) chronic myeloid leukaemia (CML). We set out to elucidate the role of Hh signaling in CP-CML and determine if inhibition of Hh signaling, through inhibition of smoothened (SMO), was an effective strategy to target CP-CML LSC. Assessment of Hh pathway gene and protein expression demonstrated that the Hh pathway is activated in CD34(+) CP-CML stem/progenitor cells...

Sonidegib selectively inhibits smoothened protein, suppresses the growth of Hedgehog pathway-dependent tumors, and has recently been approved in the indication of locally advanced basal cell carcinoma. A comprehensive exposure-response analysis was conducted to further characterize the relationship of sonidegib exposure to efficacy and safety. Minimum observed plasma concentration at pre-dose (Cmin), peak concentration (Cmax), and area under the curve were used as exposure endpoints. Exposure-efficacy analyses included data from 190 patients who received sonidegib 200 mg or 800 mg once daily in the primary efficacy study...

The Hedgehog (HH) pathway has been linked to the formation of basal cell carcinoma (BCC), medulloblastoma, and other cancers. The recently approved orally active drugs vismodegib (GDC-0449) and sonidegib (LDE-225) were not only efficacious for the treatment of advanced or metastatic BCC by antagonizing the smoothened (SMO) receptor, but also produced important side effects, limiting their use for less invasive BCC. Herein, we compared a large series of SMO antagonists, including GDC-0449 and LDE-225, the clinically tested BMS-833923, CUR-61414, cyclopamine, IPI-926 (saridegib), itraconazole, LEQ-506, LY-2940680 (taladegib), PF-04449913 (glasdegib), and TAK-441 as well as preclinical candidates (PF-5274857, MRT-83) in two SMO-dependent cellular assays and for G-protein activation...
