Intravenous Immunoglobulin (IVIG) from Bio Products Laboratory / Kedrion.
Gammaplex is an IVIG product available in 5% and 10% formulations, manufactured by Bio Products Laboratory (BPL) and distributed by Kedrion. It is FDA-approved for primary humoral immunodeficiency, with the 5% formulation also approved for chronic ITP. The dual formulations support flexibility in infusion rate and patient tolerance.
Gammaplex is FDA-approved for the following indications:
Gammaplex is administered intravenously every three to four weeks. The 5% formulation may be selected for patients who require slower infusion rates; the 10% allows shorter infusion times.
The manufacturer offers a patient support program — BPL Patient Support — that can help with insurance navigation, copay assistance for eligible patients, nursing support, and ongoing education. More information is available at https://www.bpl-us.com.
Treatment with Gammaplex is initiated and monitored by Dr. McNeil. Prior authorizations are handled in-house — patients are not asked to navigate insurance approvals on their own. Infusion logistics are coordinated through trusted partner infusion providers — including Horizon Infusions, where the practice is co-located — or arranged for home infusion when appropriate. The team handles scheduling, nursing coordination, and prior-authorization renewals.
