IMPORTANT REMINDER
We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan or government program (e.g., TennCare), the express terms of the health plan or government program will govern.
POLICY
I. INDICATIONS
The indications below including FDA-approved indications and compendial uses are considered a covered benefit provided that all the approval criteria are met and the member has no exclusions to the prescribed therapy.
A. FDA-Approved Indications
1. Nplate is indicated for the treatment of thrombocytopenia in:
a. Adult patients with immune thrombocytopenia (ITP) who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy.
b. Pediatric patients 1 year of age and older with ITP for at least 6 months who have had an insufficient response to corticosteroids, immunoglobulins, or splenectomy.
2. Nplate is indicated to increase survival in adults and in pediatric patients (including term neonates) acutely exposed to myelosuppressive doses of radiation (Hematopoietic Syndrome of Acute Radiation Syndrome [HSARS]).
B. Compendial Uses
1. Myelodysplastic syndromes, for lower risk disease in patients with severe or refractory thrombocytopenia following disease progression or no response to hypomethylating agents, immunosuppressive therapy, or clinical trial
2. Chemotherapy-induced thrombocytopenia (CIT)
All other indications are considered experimental/investigational and not medically necessary.
II. DOCUMENTATION
Submission of the following information is necessary to initiate the prior authorization review for immune thrombocytopenia and chemotherapy-induced thrombocytopenia (CIT):
A. For initial requests: pretreatment platelet counts
B. For continuation requests: current platelet counts
III. EXCLUSIONS
Coverage will not be provided for members with the following exclusion: concomitant use of Nplate with other thrombopoietin receptor agonists (e.g., Promacta, Doptelet, Mulpleta) or with spleen tyrosine kinase inhibitors (e.g., Tavalisse)
IV. PRESCRIBER SPECIALTIES
This medication must be prescribed by or in consultation with a hematologist or oncologist.
V. CRITERIA FOR INITIAL APPROVAL
A. Immune thrombocytopenia (ITP)
Authorization of 6 months may be granted for treatment of ITP when both of the following criteria are met:
1. Inadequate response or intolerance to prior therapy with corticosteroids, immunoglobulins, or splenectomy.
2. Untransfused platelet count at any point prior to the initiation of the requested medication is less than 30x109/L OR 30x109/L to 50x109/L with symptomatic bleeding (e.g., significant mucous membrane bleeding, gastrointestinal bleeding or trauma) or risk factors for bleeding (see Section VII).
B. Hematopoietic syndrome of acute radiation syndrome (HSARS)
Authorization of 1 month may be granted for treatment of hematopoietic syndrome of acute radiation syndrome (acute exposure to myelosuppressive doses of radiation).
C. Myelodysplastic Syndromes
Authorization of 12 months may be granted for treatment of myelodysplastic syndromes when both of the following criteria are met:
1. Member has lower risk disease defined as Revised International Prognostic Scoring System (IPSS-R) (Very Low, Low, Intermediate), International Prognostic Scoring System (IPSS) (Low/Intermediate-1), WHO classification-based Prognostic Scoring System (WPSS) (Very Low, Low, Intermediate).
2. Member has severe or refractory thrombocytopenia following disease progression or no response to hypomethylating agents (such as azacitidine and decitabine), immunosuppressive therapy, or clinical trial.
D. Chemotherapy-induced thrombocytopenia
Authorization of 6 months may be granted for treatment of chemotherapy-induced thrombocytopenia (CIT) when either of the following criteria are met:
1. The platelet count is less than 100x109/L for at least 3-4 weeks following the last chemotherapy administration, or
2. Chemotherapy administration has been delayed related to thrombocytopenia
VI. CONTINUATION OF THERAPY
A. Immune thrombocytopenia (ITP)
1. Authorization of 3 months may be granted to members with current platelet count less than 50x109/L for whom the platelet count is not sufficient to prevent clinically important bleeding and who have not received a maximal Nplate dose for at least 4 weeks.
2. Authorization of 12 months may be granted to members with current platelet count less than 50x109/L for whom the current platelet count is sufficient to prevent clinically important bleeding.
3. Authorization of 12 months may be granted to members with current platelet count of 50x109/L to 200x109/L.
4. Authorization of 12 months may be granted to members with current platelet count greater than 200x109/L to less than or equal to 400x109/L for whom Nplate dosing will be adjusted to achieve a platelet count sufficient to avoid clinically important bleeding.
B. Hematopoietic syndrome of acute radiation syndrome (HSARS)
All members (including new members) requesting authorization for continuation of therapy must meet all initial authorization criteria.
C. Myelodysplastic Syndromes
Authorization of 12 months may be granted for continued treatment of myelodysplastic syndromes in members who experience benefit from therapy (e.g., increased platelet counts, decreased bleeding events, reduced need for platelet transfusions).
D. Chemotherapy-induced thrombocytopenia
Authorization of 6 months may be granted for continued treatment of chemotherapy-induced thrombocytopenia (CIT) when all of the following criteria are met:
1. Member is experiencing benefit from therapy (e.g., increased platelet counts, decreased bleeding events, reduced need for platelet transfusions) to maintain a target platelet count goal of 100x109/L – 200x109/L.
2. The requested drug is used to maintain dose schedule and intensity of chemotherapy.
VII. APPENDIX
Examples of risk factors for bleeding (not all inclusive)
· Undergoing a medical or dental procedure where blood loss is anticipated
· Comorbidity (e.g., peptic ulcer disease, hypertension)
· Mandated anticoagulation therapy
· Profession (e.g., construction worker) or lifestyle (e.g., plays contact sports) that predisposes member to trauma
APPLICABLE TENNESSEE STATE MANDATE REQUIREMENTS
BlueCross BlueShield of Tennessee’s Medical Policy complies with Tennessee Code Annotated Section 56-7-2352 regarding coverage of off-label indications of Food and Drug Administration (FDA) approved drugs when the off-label use is recognized in one of the statutorily recognized standard reference compendia or in the published peer-reviewed medical literature.
ADDITIONAL INFORMATION
For appropriate chemotherapy regimens, dosage information, contraindications, precautions, warnings, and monitoring information, please refer to one of the standard reference compendia (e.g., the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) published by the National Comprehensive Cancer Network®, Drugdex Evaluations of Micromedex Solutions at Truven Health, or The American Hospital Formulary Service Drug Information).
