Unfortunately, none of the provided sources contain information about the expiration date of the Yervoy discount. However, the sources provide valuable information about the drug and its use.

Yervoy (ipilimumab) is a biologic drug used to treat advanced melanoma, a type of skin cancer. It works by activating the immune system to attack cancer cells [1]. The drug was first approved by the FDA in 2011 [3].

A recent study showed that the combination of Yervoy and Opdivo (nivolumab), another immune checkpoint inhibitor, demonstrated long-term survival benefits in patients with advanced melanoma [2]. The study showed that the combination therapy resulted in a 52% overall survival rate at six and a half years [2].

The FDA-approved label for Yervoy contains information about the dosage, administration, and potential side effects of the drug [3]. Patients should consult with their healthcare provider for specific information about their treatment plan and any available discounts or financial assistance programs.

In conclusion, while the sources do not provide information about the expiration date of the Yervoy discount, they do provide valuable information about the drug and its use in the treatment of advanced melanoma. Patients should consult with their healthcare provider for specific information about their treatment plan and any available discounts or financial assistance programs.
