Production and delivery tracking and sample verification of patient-specific therapeutics
Systems and methods for tracking biological samples are presented. Intrinsic and extrinsic biological sample data and/or intrinsic and extrinsic patient data may be used to label a biological sample obtained at a point-of-care facility, which may be sent to a processing facility, wherein the labeled biological sample undergoes analysis and/or processing into a labeled therapeutic. The labeled therapeutic is delivered back to the point-of-care facility, wherein the labeled therapeutic is tested for the presence of the additives prior to administration to a patient. Multi-factor validation is performed, including validating the identity of the patient to a container, validating the identity of the labeled biological sample/therapeutic to the container, and thus, validating the identity of the labeled therapeutic to the patient. The entire life cycle of a biological sample used to generate a personalized therapeutic is validated, and ensures that mix-ups or errors in administration are reduced or eliminated.
1 . A method of tracking a labeled biological sample through a manufacturing process, the method comprising:
receiving the labeled biological sample at a manufacturing facility, wherein the biological sample is labeled with one or more first additives by inserting the one or more first additives into a container comprising the biological sample, wherein the one or more first additives uniquely label the biological sample among a population of biological samples, and wherein the one or more first additives include at least one of a primer, a monoclonal antibody, a rare earth metal, an isotope, or an autologous mitochondria;
validating the labeled biological sample by detecting a presence of the one or more first additives and comparing the detected one or more first additives to a listing of additives provided in first identifying data corresponding to the labeled biological sample;
generating an initial block of a sample tracking chain using a sample tracking engine, wherein the initial block comprises the first identifying data;
storing the initial block as part of the sample tracking chain in a sample database, wherein the sample tracking chain is indexed and thereby searchable for the first identifying data and the one or more first additives;
for each manufacturing step of a manufacturing process for generating a labeled therapeutic:
accessing the sample tracking chain from the sample database;
retrieving a previous sample state object from the sample tracking chain;
generating a current state of the labeled therapeutic, wherein the current state includes manufacturing data unique to a corresponding manufacturing step for generating the labeled therapeutic;
instantiating a current sample state object in memory as a function of the current state and the previous sample state object;
linking the current sample state object to the previous sample state object in the sample tracking chain; and
updating the sample tracking chain in the sample database with the current sample state object; and
subsequent to completion of all manufacturing steps of the manufacturing process, sending the labeled therapeutic comprising one or more second additives to a point of care for administration to a patient; and
performing an assay on the labeled therapeutic at the point of care, thereby validating the labeled therapeutic for administration to the patient, by detecting the presence of the one or more second additives via an assay which uniquely labels the therapeutic among a population of therapeutics, wherein the validation is added to the sample tracking chain, wherein the validation includes validating a timestamp of a state block of a distributed digital ledger associated with second identifying digital data, based on an external public ledger, to confirm the state block associated with the second identifying digital data has not been modified or tampered with, and the sample tracking chain is indexed and thereby searchable for the second identifying digital data and the one or more second additives.
