    Indication

    Vismodegib is indicated for patients with basal cell carcinoma (BCC) which has metastasized to other parts of the body, relapsed after surgery, or cannot be treated with surgery or radiation.[2][4]

    Mechanism of action

    The substance acts as a cyclopamine-competitive antagonist of the smoothened receptor (SMO) which is part of the hedgehog signaling pathway.[3] SMO inhibition causes the transcription factors GLI1 and GLI2 to remain inactive, which prevents the expression of tumor mediating genes within the hedgehog pathway.[5] This pathway is pathogenetically relevant in more than 90% of basal-cell carcinomas.[6]

    Side effects

    In clinical trials, common adverse effects included gastrointestinal disorders (nausea, vomiting, diarrhoea, constipation), muscle spasms, fatigue, hair loss, and dysgeusia (distortion of the sense of taste). The effects were mostly mild to moderate.[1]

    gollark: I mean, you can buy basic food products around that cost here as far as I know, although you would still have to pay rent and utilities.
    gollark: I do get coverage basically anywhere I go on my network, so it seems fine.
    gollark: Oh, our internet connection is £35 a month or so.
    gollark: I would compare it to coffee cup costs but I realized I don't know how expensive they are.
    gollark: Anyway, £9 a month is cheap by UK standards I think.
