Generic Medicine Info
Indications and Dosage
Oral
Locally advanced basal cell carcinoma
Adult: In cases that have recurred following surgery or radiation therapy, or in those who are not eligible for surgery or radiation therapy: 200 mg once daily. Continue until disease progression or unacceptable toxicity occurs. Dose reduction, dosing interruption, or discontinuation may be required according to individual safety or tolerability (refer to detailed product guidelines).
Administration
Should be taken on an empty stomach. Take at least 1 hr before or 2 hr after a meal.
Contraindications
Women of childbearing potential who cannot comply with pregnancy prevention programme (i.e. using 2 methods of recommended contraception). Pregnancy and lactation. Concomitant use with strong CYP3A inhibitors, and strong and moderate CYP3A inducers.
Special Precautions
Patient with neuromuscular disorders (e.g. inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis, spinal muscular atrophy).
Adverse Reactions
Significant: Musculoskeletal toxicity (including muscle spasms, musculoskeletal pain, and myalgia), increased serum creatine kinase levels.
Blood and lymphatic system disorders: Anaemia, lymphocytopenia.
Gastrointestinal disorders: Diarrhoea, abdominal pain, nausea, vomiting, dysgeusia, dyspepsia, constipation, GERD.
General disorders and administration site conditions: Fatigue, pain.
Investigations: Decreased weight; increased serum creatinine, lipase, ALT/AST and amylase.
Metabolism and nutrition disorders: Decreased appetite, dehydration, hyperglycaemia.
Musculoskeletal and connective tissue disorders: Myopathy.
Nervous system disorders: Headache.
Reproductive system and breast disorders: Amenorrhoea.
Skin and subcutaneous tissue disorders: Alopecia, abnormal hair growth, pruritus, rash.
Monitoring Parameters
Obtain serum creatine kinase and serum creatinine at baseline and periodically during treatment. Verify pregnancy status of women of childbearing potential prior to initiation of treatment. Monitor liver function; signs or symptoms of musculoskeletal adverse reactions (e.g. unexplained muscle pain, tenderness, weakness).
Drug Interactions
Increased plasma concentrations with moderate CYP3A inhibitors (e.g. erythromycin).
Potentially Fatal: Concomitant use with strong CYP3A inhibitors (e.g. ketoconazole, ritonavir, telithromycin, nefazodone) increases the plasma concentration and efficacy of sonidegib. Strong and moderate CYP3A inducers (e.g. rifampicin, carbamazepine, phenytoin, efavirenz) decreases the plasma concentration and efficacy of sonidegib.
Food Interaction
Increased bioavailability with food. Increased systemic exposure with a high-fat meal. Concomitant use with St. John's wort decreases the plasma concentration and efficacy of sonidegib.
Action
Description: Sonidegib selectively inhibits Hedgehog (Hh) pathway by binding to the Smoothened (SMO) transmembrane protein, thereby inhibiting Hh signalling and consequently blocking signal transduction.
Synonyms: erismodegib; LDE-225.
Pharmacokinetics:
Absorption: Poorly absorbed from the gastrointestinal tract. Increased systemic exposure with a high-fat meal. Bioavailability: <10%; increased with food. Time to peak plasma concentration: 2-4 hours.
Distribution: Plasma protein binding: >97%.
Metabolism: Metabolised mainly in the liver by CYP3A4 isoenzyme.
Excretion: Mainly via faeces (approx 70%); urine (30%). Elimination half-life: Approx 28 days.
