STABILITY TESTING AS A QUALITY CONTROL MEASURE White Paper

Stability testing is, in essence, a quality control process and is therefore a vital component of every phase of clinical development for both large and small molecules – from early phase through to and including post approval. It should be treated as an ongoing program rather than as a periodic exercise.

Frontage Simoa

VALIDATING THE SIMOA TECHNOLOGY White Paper

Most of the advanced instruments used in bioanalysis—such as Gas Chromatography (GC), High Performance Liquid Chromatography (HPLC), and Liquid Chromatography-Mass Spectrometry (LC-MS) for example—are automated. Thus, they are controlled by complex computer systems, and the information they generate is stored electronically. If these systems are to be used in regulated research studies in the US, EU, and Japan, the instruments themselves must be qualified and their supporting software and processes must be validated as meeting regulatory requirements.

CMC 5m 60x78 - Outsourcing Analytical Testing For Biologics - A CRO’S Perspective White Paper

Outsourcing Analytical Testing For Biologics – A CRO’S Perspective White Paper

Biologics are complex large molecules derived from living organisms or manufactured from cells, and they have inherent structural heterogeneity. Indeed, proteins, given their chemistry, are the “most structurally complex and functionally sophisticated molecules known.”1
Thus, the analytical testing required to support Chemical, Manufacturing, and Controls (CMC) activities of biologics is highly sophisticated, and is becoming more so as the modalities of biologics grow more complex (with antibody drug conjugates, conjugate vaccines, PEGylated proteins, fusion proteins, gene therapies, and cell-based therapies).

Capture 1 60x78 - Pre-Existing Antibodies within Immunogenicity Testing

Pre-Existing Antibodies within Immunogenicity Testing

Monoclonal antibodies and next generation molecules such as antibody-drug conjugates (ADC) are being developed and moved into early phase clinical testing. These new molecules bring challenges for measuring immunogenicity within human serum samples.
Challenges:
• Therapeutic monoclonal antibodies could have structural regions which could contain ADA binding domains [Figure 1].
• ADC molecule has a mAb joined to a small drug by a linker region [Figure 2]. This may lead to a highly potent drug which is also a selective binder of a specific tumor antigen; however, the structure may also present a neoepitope to the immune system.
• Development of anti-drug antibody (ADA) assays to both mAb’s and ADC’s very commonly has demonstrated the presence of pre-existing antibodies (PEXA) in a small percentage of drug naïve normal human serum samples. It is currently unclear as to the evolutionary mechanism that has allowed PEXA to develop. Their presence may serve as a regulatory mechanism to suppress the immune system under certain conditions.
Approach:
• Regardless of how pre-existing antibodies may have developed, measuring an anti-drug antibody (ADA) response in serum samples may present additional challenges with these pre-existing molecules present. Here, we outline a strategy to determine where on the molecule the ADA reactivity is directed against.

Capture 60x78 - Characterization of Interchain Cysteine Linked Antibody Drug Conjugates in Mouse Plasma by LC/MS

Characterization of Interchain Cysteine Linked Antibody Drug Conjugates in Mouse Plasma by LC/MS

Antibody drug conjugates (ADCs) has become promising therapy for the treatment of cancers. Among all the ADCs under developing, 2/3 of them are interchain cysteine linked ADCs. The ADCs are manufactured by partially reduce the 4 pairs of interchain disulfide bond followed by conjugate cytotoxic payloads to the thiols, as a consequence, the antibodies are linked with 0, 2, 4, 6, 8 drugs. The drug to antibody ratio (DAR) and the drug linking position are important parameters that affect the therapeutic effects and need to be well characterized.
Sample preparation:
The ADCs in the mouse plasma were purified by affinity capture with anti-human IgG beads followed wash with PBS supplied with 0.1% tween-20. The ADC was eluted with 0.1% TFA and neutralized with 1M tris (PH=8).
Challenges:
1. Heavy chain positional isomers separation and Identification.
2. Heavy chain positional isomers abundance determination.
Methods:
1. Reduced ADC HRMS analysis. The Purified ADC was deglycosylated and reduced and then analyzed with HRMS.
2. Bottom up analysis. Purified ADC was treated with IdeS to remove Fc part followed by denaturation, reduction, alkylation, chymotrpsin digestion and then subject to LC/MS analysis.
3. LC-MS/MS analysis. Isomer fraction were collected and digested with trypsin, the digest was analyzed by LC/MS/MS for drug linking position identification.
