Description: |
Erythropoietic protoporphyria (EPP) is an autosomal recessive porphyria that can cause severe sensitivity to sunlight, gallstones, cholestatic hepatitis, and liver damage. EPP is caused by a deficiency of ferrochelatase in the heme biosynthetic pathway. This results in accumulation of protoporphyrin in the bone marrow, red blood cells, plasma, skin, and liver. Severe neuropathic pain is caused when the accumulated phototoxic protoporphyrin is activated by visible light, including sunlight and some artificial light, and triggers singlet oxygen free radical reactions. The pain can last for hours to days. Cholestatic hepatitis and gallstone results from accumulation of protoporphyrin in the liver in amounts that are damaging to hepatocytes and cholangiocytes. Liver damage caused by EPP is rare and affects fewer than 5% of cases. In severe cases, cholestatic hepatitis can progress to liver failure requiring transplantation.
Afamelanotide is a synthetic tridecapeptide and structural analog of α-melanocyte stimulating hormone. It is a melanocortin receptor agonist and binds predominantly to melanocortin 1 receptor increasing pain free light exposure in adult individuals with a history of phototoxic reactions from erythropoietic protoporphyria. Afamelanotide increased the production of eumelanin in the skin independently of exposure to sunlight or artificial ultraviolet light sources.
Regulatory Status
Afamelanotide (e.g., Scenesse™) was approved by the U.S. Food and Drug Administration (FDA) on October 8, 2019 to increase pain free light exposure in adult individuals with a history of phototoxic reactions from erythropoietic protoporphyria.

Policy/ Coverage: |
Does Not Meet Primary Coverage Criteria Or Is Investigational For Contracts Without Primary Coverage Criteria
The use of Afamelanotide (e.g., Scenesse™) to increase pain free light exposure in adult individuals with a history of phototoxic reactions from erythropoietic protoporphyria or for any other indication or circumstance does not meet primary coverage criteria that there be scientific evidence of effectiveness in improving health outcomes.
For members with contracts without primary coverage criteria, the use of Afamelanotide to increase pain free light exposure in adult individuals with a history of phototoxic reactions from erythropoietic protoporphyria or for any other indication or circumstance is considered investigational.
Investigational services are specific contract exclusions in most member benefit certificates of coverage.

Rationale: |
The FDA approval of Afamelanotide (e.g., Scenesse™) was based on two Phase 3 multicenter, randomized, double-blind, placebo-controlled trials. The first study was completed in the European Union and patients received Afamelanotide (e.g., Scenesse™) or placebo for 9 months. The second study was completed in the United States and patients received Afamelanotide (e.g., Scenesse™) or placebo for 6 months. Eligibility criteria were the same in the two trials; patients must be 18 years of age or older, must have a biochemically confirmed erythropoietic protoporphyria, and must not have a clinically significant hepatic or other organ dysfunction, skin cancer, or premalignant lesions or other photodermatoses. Patients with a history of drug or alcohol abuse and pregnant females were excluded from the trials. In both studies patients were randomly assigned to receive either an implant formulation of 16 mg of Afamelanotide (e.g., Scenesse™) or a placebo implant formulation in a 1:1 ratio. Implants were inserted in the subcutaneous fat above the iliac crest with a 14-gauge catheter needle and then pushed into the fat tissue with a 16-gauge stylet.
Mild to moderate adverse events occurred in both study groups and included headache, nausea, nasopharyngitis, and back pain. Serious adverse events in both the Afamelanotide (e.g., Scenesse™) and placebo group were considered by the principal investigator to be unrelated to the study drug. There was no evidence in either study that Afamelanotide (Scenesse™) had any impact on gallstones, cholestasis, cirrhosis, or liver failure (Langendonk 2015). Afamelanotide (e.g., Scenesse™) does provide treatment of symptoms in patients with erythropoietic protoporphyria in regard to light exposure. However current evidence does not indicate that high levels of protoporphyrin are affected with Afamelanotide (e.g., Scenesse™) treatment. The evidence for efficacy is insufficient to meet primary coverage criteria.
2021 Update
Annual policy review completed with a literature search using the MEDLINE database through June 2021. No new literature was identified that would prompt a change in the coverage statement.
2022 Update
Annual policy review completed with a literature search using the MEDLINE database through June 2022. No new literature was identified that would prompt a change in the coverage statement.
2023 Update
Annual policy review completed with a literature search using the MEDLINE database through June 2023. No new literature was identified that would prompt a change in the coverage statement.
2024 Update
Annual policy review completed with a literature search using the MEDLINE database through June 2024. No new literature was identified that would prompt a change in the coverage statement.
