Erivedge (Vismodegib) and Odomzo (Sonidegib) in Skin Cancer Treatment


In the evolving landscape of skin cancer treatment, targeted therapies have emerged as promising options, bringing new hope to patients facing challenging diagnoses. Among these advancements, Erivedge (Vismodegib) and Odomzo (Sonidegib) stand out as oral medications designed to combat specific types of skin cancer. This blog post will explore the mechanisms of action, efficacy, cure rates, side effects, precautions, and contraindications associated with these therapies, offering a comprehensive comparison to aid in understanding their respective roles in skin cancer treatment.

Mechanism of Action:

Both Erivedge and Odomzo belong to a class of medications known as hedgehog pathway inhibitors. “The hedgehog pathway is involved in cell growth regulation,” explains Dr. Adam Mamelak, skin cancer specialist in Austin, Texas.  Aberrations in this pathway are often implicated in the development of certain skin cancers, particularly basal cell carcinoma (BCC).

Erivedge (Vismodegib): It works by selectively inhibiting the hedgehog pathway, thereby suppressing the growth of cancer cells.

Odomzo (Sonidegib): Similar to Erivedge, Odomzo inhibits the hedgehog pathway, blocking signals that drive the uncontrolled growth of cancer cells.

Efficacy and Cure Rates:

Both medications have demonstrated efficacy in the treatment of locally advanced and metastatic basal cell carcinoma. Studies have reported high response rates, with a significant number of patients experiencing tumor shrinkage or stabilization. While these therapies show promise in managing advanced BCC, the concept of “cure rates” may vary, and long-term outcomes are still being studied.

Side Effects:

Erivedge and Odomzo may cause common side effects, including muscle spasms, hair loss, fatigue, and nausea. However, it’s crucial to note that each patient’s response to the medication is unique, and side effects can vary in severity. Skin-related adverse events, such as changes in hair texture and loss of taste, have also been reported.

Precautions and Contraindications:

Both medications come with precautions and contraindications that must be considered before initiation. Pregnant women or those planning to become pregnant should avoid these medications, as they may cause harm to the developing fetus. Close monitoring and contraception are recommended during and after treatment.

Comparison and Contrast:

1. Administration: Erivedge is typically taken once daily, whereas Odomzo is taken once daily on an empty stomach.

2. Efficacy: Both drugs have demonstrated efficacy in treating advanced BCC, but individual patient responses may vary.

3. Side Effects: While both medications share common side effects, the intensity and specific side effects experienced can differ among patients.

4. Precautions: Pregnancy avoidance and contraception are crucial considerations for both drugs due to potential teratogenic effects.

5. Contraindications: Both drugs are contraindicated in pregnancy, and caution should be exercised in patients with a history of certain medical conditions.


Erivedge (Vismodegib) and Odomzo (Sonidegib) represent significant strides in the treatment of advanced basal cell carcinoma. While both medications share similarities in mechanism of action and indications, individual patient factors and preferences may influence the choice between them. Close collaboration with a healthcare professional is essential to weigh the risks and benefits, ensuring that patients receive the most appropriate and effective treatment for their specific condition.
