ZYNYZ is a medicine that may treat a certain type of skin cancer by working with your immune system. ZYNYZ can cause your immune system to attack normal organs and tissues in any area of your body and can affect the way they work. These problems can sometimes become severe or life-threatening and can lead to death. You can have more than one of these problems at the same time. These problems may happen anytime during treatment or even after your treatment has ended.
Call or see your healthcare provider right away if you develop any new or worsening signs or symptoms, including:
Lung problems
Intestinal problems
Liver problems
Hormone gland problems
Kidney problems
Skin problems
Problems can also happen in other organs and tissues. These are not all of the signs and symptoms of immune system problems that can happen with ZYNYZ. Call or see your healthcare provider right away for any new or worsening signs or symptoms, which may include:
Infusion reaction that can sometimes be severe. Signs and symptoms of infusion reactions may include:
Rejection of a transplanted organ. Your healthcare provider should tell you what signs and symptoms you should report and monitor you, depending on the type of organ transplant that you have had.
Complications, including graft-versus-host disease, in people who have received a bone marrow (stem cell) transplant that uses donor stem cells (allogeneic). These complications can be serious and can lead to death. These complications may happen if you underwent transplantation either before or after being treated with ZYNYZ. Your healthcare provider will monitor you for these complications.
Getting medical treatment right away may help keep these problems from becoming more serious. Your healthcare provider will check you for these problems during your treatment with ZYNYZ. Your healthcare provider may treat you with corticosteroid or hormone replacement medicines. Your healthcare provider may also need to delay or completely stop treatment with ZYNYZ if you have severe side effects.
ZYNYZ is a prescription medicine used to treat a type of skin cancer called Merkel cell carcinoma in adults. ZYNYZ may be used to treat your skin cancer when it has spread or returned.
It is not known if ZYNYZ is safe and effective in children.
ZYNYZ was evaluated in a clinical study in people with Merkel cell carcinoma. The initial assessment that led to the approval of ZYNYZ included 65 people who had Merkel cell carcinoma that had spread or returned. Some people in the study had surgery or radiation for their condition before treatment with ZYNYZ. None of the 65 people in the initial assessment received prior therapies like chemotherapy.
The study measured:
*Disappearance of all signs of cancer in response to treatment does not always mean the cancer has been cured.
