Embryo-Fetal Toxicity

• Erivedge can cause embryo-fetal death or severe birth defects when administered to a pregnant woman. Erivedge is embryotoxic, fetotoxic, and teratogenic in animals. Teratogenic effects included severe midline defects, missing digits, and other irreversible malformations

• Verify pregnancy status of females of reproductive potential within 7 days prior to initiating Erivedge therapy. Advise females of reproductive potential to use effective contraception during and after Erivedge therapy. Advise males of the potential risk of Erivedge exposure through semen and to use condoms with a pregnant partner or a female partner of reproductive potential. Advise pregnant women of the potential risks to a fetus

• Advise female patients and female partners of male patients to contact their healthcare provider with a known or suspected pregnancy. Report pregnancies to Genentech at (888) 835‑2555
  

Female Patients

• Advise females of reproductive potential to use effective contraception during therapy with Erivedge and for 24 months after the final dose
  

Male Patients

• Advise males of the potential risk to an embryo or fetus if a female partner of reproductive potential is exposed to Erivedge. Advise male patients to use condoms with a pregnant partner or a female partner of reproductive potential, even after a vasectomy, during therapy and for 3 months after the final dose of Erivedge
  

Blood Donation

• Advise patients not to donate blood or blood products while receiving Erivedge and for 24 months after the final dose of Erivedge
  

Semen Donation

• Vismodegib is present in semen. It is not known if the amount of vismodegib in semen can cause embryo-fetal harm. Advise male patients not to donate semen during and for 3 months after the final dose of Erivedge
  

Premature Fusion of the Epiphyses

• Premature fusion of the epiphyses has been reported in pediatric patients exposed to Erivedge. In some cases, fusion progressed after drug discontinuation

Adverse Reactions

• The most common adverse reactions (≥10%) were muscle spasms, alopecia, dysgeusia, weight loss, fatigue, nausea, diarrhea, decreased appetite, constipation, arthralgias, vomiting, and ageusia
• Amenorrhea can occur in females of reproductive potential. Reversibility of amenorrhea is unknown. In clinical trials, a total of 3 of 10 pre-menopausal women developed amenorrhea while receiving Erivedge
• Treatment-emergent Grade 3 laboratory abnormalities observed in clinical trials were hyponatremia in 6 patients (4%), hypokalemia in 2 patients (1%), and azotemia in 3 patients (2%)
• Additionally, in a post-approval clinical trial conducted in 1232 patients with locally advanced or metastatic BCC treated with Erivedge, a subset of 29 patients had baseline values for CPK reported. Within the subset of patients, 38% had a shift from baseline, and one of the patients had a Grade 3 value. The prevalence of Grade 3/4 CPK elevation across the entire study population with any CPK measurement was 2.4% (11 out of 453 patients)

Use in Specific Populations

Lactation

• No data are available regarding the presence of vismodegib in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production. Because of the potential for serious adverse reactions in breastfed infants from Erivedge, advise a nursing woman that breastfeeding is not recommended during therapy with Erivedge and for 24 months after the final dose
