16/09/2020: Theradiag announces the launch of a new range of assays for automated Therapeutic Drug Monitoring of Biologics for use on IDS-iSYS

On September 16, 2020 THERADIAG (ISIN: FR0004197747, Ticker: ALTER, eligible for the French PEA-PME personal equity plan), a company specializing in in vitro diagnostics and theranostics, reported the launch of four new i-Tracker assays designed to run on the automated IDS-iSYS analyser (Press release, Theradiag, SEP 16, 2020, View Source [SID1234565221]). These assays were developed by Theradiag to address the rapidly growing market of biologics drug monitoring.

The four i-Tracker assays: i-Tracker Infliximab, i-Tracker Anti-Infliximab, i-Tracker Adalimumab and
i-Tracker Anti-Adalimumab were previously launched on the i-Track10 analyser, an instrument manufactured by IDS for Theradiag.

In the six months since the Theradiag launch, the assays have undergone validation on the IDS-iSYS analyser and are now available for use on the installed base of IDS-iSYS analysers in countries accepting the CE mark.

About Therapeutic Drug Monitoring (TDM) of Biologics

Biologic drugs such as Infliximab and Adalimumab have revolutionized the management of Chronic Inflammatory Diseases such as Inflammatory Bowel Disease, Rheumatoid Arthritis, and Psoriasis. A significant proportion of patients may still experience either non-response to the therapy or a loss of response over time.

TDM assays provide information for therapeutic decisions to maximize response and minimize overexposure to the drugs, and their use is included in many clinical guidelines. It is estimated that around 2 million patients worldwide are treated with Infliximab and Adalimumab.

About the i-Tracker tests

The i-Tracker tests are the first random access automated chemiluminescent (CLIA) tests for TDM of Biologics and give precise results in a very short time for an immediate adjustment of treatment by clinicians.

The drug measurement kits measure the serum/plasma levels of biologics which are used in the treatment of many inflammatory diseases. The Anti-drug kits measure the antibodies that a patient may raise against the drugs, causing a decrease in treatment efficacy. The kits are validated both on the princeps molecules and on biosimilars and are standardized according to the international standards of the World Health Organization (WHO).

Bertrand de Castelnau, CEO of Theradiag commented: "Theradiag was the first to introduce the random access approach and the CLIA technology for its range of TDM of Biologics and we are glad to now make these products available for the many users of IDS-iSYS instruments. Access to this large installed base will help increase adoption of TDM for the well-being of patients."

Jaap Stuut, CEO of IDS added: "We are pleased to see that validation of these biologics monitoring markers has been completed successfully. IDS has distribution rights for these unique assays in a number of key markets, and making the kits available to our installed base of customers is a crucial step in the distribution strategy. These tests also complement our continued focus on auto-immune diseases, as therapeutic drug monitoring is often performed by the same immunology teams."

Competitive New Data from ADCs Based on Synaffix Proprietary Exatecan Linker-Payload

On September 16, 2020 Synaffix B.V., a biotechnology company enabling antibody-drug conjugates (ADCs) with best-in-class therapeutic index, based on proprietary GlycoConnect, HydraSpace and toxSYN technology platforms, reported promising findings from its latest in vivo benchmarking study (Press release, Synaffix, SEP 16, 2020, View Source [SID1234565220]).

In this mouse BT-474 xenograft study, trastuzumab-based ADCs prepared using Synaffix’s proprietary SYNtecan E linker-payload demonstrated an efficacy profile equivalent to deruxtecan-based ADCs. SYNtecan E is an exatecan-based linker-payload that contains the HydraSpace polar spacer technology, a conventional dipeptide cleavable linker and is conjugated, in this study, to the native antibody glycan using GlycoConnect. Deruxtecan is the linker-payload used in Enhertu, the FDA-approved ADC indicated for previously treated, HER-2 positive unresectable or metastatic breast cancer.

Following just a single dose, both HER-2-targeting ADCs, which have the same drug-to-antibody ratio (DAR) and administered at the same dose level, achieved complete tumor regression.

A poster of the data will be presented at the World ADC Digital conference on Thursday, 17 September 2020 at 3:30p-4:00p EDT.

Floris van Delft, CSO of Synaffix said:

"Given the recent clinical and commercial success observed with deruxtecan-based ADCs, we have been very excited with our first data for ADCs with the same mechanism of action."

"Exatecan mesylate has completed Phase 3 studies as a single agent already and comes with a well-understood toxicology profile. That said, its relatively challenging biophysical properties have likely contributed to limited exploration within the ADC context to date, despite its high potency and putative bystander killing potential. We have resolved the ADC aggregation issue by combining exatecan with our highly polar HydraSpace technology, providing highly stable and efficacious ADCs. We look forward to presenting further data on this new linker-payload and introducing it to our collaborators in due course."

Deruxtecan and SYNtecan E both belong to the family of camptothecins and are potent DNA topoisomerase 1 inhibitors that release DXd and exatecan as the active catabolite respectively.

SYNtecan E represents one of multiple options within the toxSYN linker-payload platform, which spans multiple mechanisms of action and can be evaluated in combination with GlycoConnect and HydraSpace technologies. This consolidated ADC platform enables any company with an antibody to rapidly co-discover an ADC with Synaffix and then develop and market the resulting ADC as part of its own pipeline under a license agreement.
