A recently granted patent (Publication Number: US11903965B2) outlines a method for preserving pre-beta high density lipoprotein for administration to patients. The method involves obtaining delipidated plasma containing the pre-beta high density lipoprotein, testing the concentration of the protein, preserving the plasma for a period ranging from one week to three years, and then preparing it for administration. The preserved plasma is tested again to ensure the concentration of the pre-beta high density lipoprotein is above an acceptable threshold level before being administered to the patient. The process includes steps such as modifying the protein concentration, freezing the batch at temperatures below -30°C, and thawing the plasma in a specific temperature range before administration.

Additionally, the patent describes a method for preserving modified high density lipoproteins for patient administration. This method involves obtaining delipidated plasma containing the modified high density lipoproteins, testing the concentration of the protein, preserving the plasma for a specified period, and preparing it for administration after confirming the protein concentration is within an acceptable range. Similar to the previous method, steps such as modifying the protein concentration, freezing the batch at temperatures below -30°C, and storing the thawed plasma at specific temperatures for a limited time are outlined. The patent aims to provide a detailed process for preserving and administering high density lipoproteins to patients, ensuring the efficacy and safety of the treatment.
