While attending the 2018 Workshop...
Protein characterization is a broad term describing the profile or fingerprint of a large molecule’s (or biologic’s) physical, chemical, and biological properties. Characterization of the protein will test the purity, activity, and the quantity of the protein. Methods for quantification include chromatography methods such as high-performance liquid chromatography (HPLC) or...
Adoption of technology has a life cycle that typically follows a bell-shaped curve. There are early adopters, early majority, late majority, and laggards. Adopting technology early comes with a risk, as not all technologies are widely adopted and many are very short lived. Adopting late also comes with a risk,...
The FDA has not approved marijuana for any indication, as it continues to retain Schedule I designation. However, a key component of marijuana (D9-Tetrahydrocannabinol or THC) and several synthetic analogues have been approved by the FDA or are under clinical investigation. Whether the FDA will consider approving marijuana in the...
The FDA has regulated cigarettes, smokeless and loose tobacco since 2009 under the Tobacco Control Act. In 2016, the FDA finalized a rule for the regulation of all tobacco products, making it illegal to sell e-cigarettes, cigars and hookah tobacco to anyone under 18 and requiring retailers to check photo...
Immuno-oncology is a growing field. The goal is to augment the patient’s immune system to attack the cancer cells. The current lines of treatment for cancer are radiation, chemotherapy, and surgical resection. If these treatments do not work, physicians can seek alternative treatments, such as immune-oncology therapeutics. Two emerging immune-oncology...

Several important classes of drugs are inherently unstable in biological fluids. Examples include alkylating agents, cytostatic nucleosides, drugs with ester, aldehyde, thiol, nitroxyl or lactone functional groups, and small molecule compounds with unstable metabolites, such as acylglucuronides. The rate at which an analyte degrades in blood, other biological fluids,...
The 505(b)(2) drug development path, in contrast to traditional development of a new, never been approved drug (described under 505(b)(1) of the Federal Food, Drug, and Cosmetic Act) or ANDA (described under Section 505(j) of the Act) for a generic drug that is no longer under patent protection, is an...
Designing a tissue assay in accordance to the FDA bioanalytical method validation (BMV) guidance involves three key questions. First, can control tissue be easily obtained in bulk quantities or should a surrogate tissue approach be considered? Second, what sample processing procedures should be considered relative to the known stability of...

Immunogenicity, why do we keep talking about it? Immunogenicity can, in the simplest of terms, be described as a subject’s ability to generate antibodies specific to the dosed protein therapeutic. While stating it this way understates the complexity of the immune system and the methods needed to detect and characterize...
Surprisingly, there are a number of drug development companies that do not obtain stable isotope-labeled internal standards (SIL-IS) for their bioanalytical methods. Instead they settle for using a surrogate internal standard (a compound that closely resembles the measured analyte) which can lead to unreliable data and be detrimental to a...
What you don’t know about how an off-the-shelf Biomarker kit is evaluated and qualified can significantly compromise your biomarker data. Running the kit using the manufacturer’s instructions without systematically testing the accuracy/precision (A/P), range of quantification (ROQ), dilutional linearity (DL), stability, and selectivity can jeopardized the interpretation of the results. The...
There is regulatory requirement that the cumulative time a frozen pharmacokinetic sample has been thawed – from the time it’s removed from the freezer to the time it’s returned – be documented. Freeze/thaw cycle data is not deemed sufficient alone, since a study sample might have been thawed for extended...
