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…

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…

Measuring new biotherapeutic modalities such as cellular therapies are not well defined in the regulatory landscape. Currently no white papers or guidelines are available to help navigate the murky waters of quantifying new modalities, which is why the AAPS PK focus group has set a course toward providing the field…

In pursuit of KCAS’ Mission to provide reliable and defendable data, quality is one of our core values. It is the responsibility of every employee to provide an always improving, high-level performance in all we do. Our independent Quality Assurance Unit (QAU) assures management that Operations is performing in conformance…

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.

Like the old adage, “you get out of it what you put into it,” good study design is a prerequisite of good data. To boost the chances of generating accurate and informative facts over the course of a study, it is key to consider all of the supporting parameters that…

Finding a laboratory to successfully transfer and GLP validate your PK method can be a challenge. Yes sure the big labs can do it, but if you are not a preferred provider you may find yourself working with the B team that doesn’t move as fast as you need, and…

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…

The challenges and obstacles to including flow cytometry in multi-center clinical trials are well-known. The solutions the KCAS team offers can eliminate risks commonly associated with lost or delayed shipments and allow for batching, which reduces the overall cost of conducting flow cytometric testing. As a result, our customers can…

The Department of Health and Human Services (HHS) has issued long awaited, comprehensive update on how medical research should be conducted. The Common Rule, 45 CFR 46 subpart A, issued 26 years ago and established basic protections for human subjects in research conducted by or supported by the HHS and…
