Study Notes
Monoclonal Antibodies
- Drug examples: ipilimumab (Yervoy), nivolumab (Opdivo), pembrolizumab (Keytruda)
- Mechanism: Bind to cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4), enhancing T-cell activation against melanoma cells.
- Monitoring:
- Liver function tests (LFTs) and thyroid function tests
- Symptoms of enterocolitis, hepatotoxicity, and dermatitis
- Motor and sensory deficits
- Adrenal insufficiency, hyper- or hypothyroidism
- Patient Education:
- Risk of severe and fatal immune-mediated reactions
- Immediate notification of healthcare provider (HCP) if symptoms occur
- Report symptoms of enterocolitis, hepatitis, skin reactions, neuropathies, endocrinopathies, pneumonitis, nephritis, or encephalitis.
Oncolytic Virus
- Drug example: talimogene (Imlygic)
- Mechanism: Genetically modified attenuated herpes simplex virus (HSV 1) that infects and kills melanoma cells.
- Monitoring:
- Flulike symptoms (fatigue, nausea, fever, chills) or pain at the treatment site.
- Patient Education:
- Potential for virus spread to other body areas or close contacts
- Pregnant and breastfeeding women should avoid this medication
- Avoid direct contact between treatment site, dressings, or body fluids and close contacts
- Wear gloves for dressing changes
- Keep treatment sites covered for at least a week after each treatment and replace loose or fallen dressings
- Dispose used dressings in sealed plastic bags.
- Do not touch or scratch the treatment site
- Immediate notification of HCP if symptoms of herpes infection develop (pain, burning or tingling in a blister around the mouth, genitals, fingers, or ears), eye pain, discharge, blurred vision or sensitivity to light, weakness in arms or legs, extreme drowsiness, or mental confusion.
