Quotient Limited Reports Blood Grouping Concordance Data From MosaiQ Verification and Validation Studies and Updates on the Completion of Its Sale Leaseback Transaction

JERSEY, Channel Islands, March 26, 2018 (GLOBE NEWSWIRE) -- Quotient Limited (NASDAQ:QTNT), a commercial-stage diagnostics company, today reported: (i) concordance data for the MosaiQ blood grouping microarray generated in recent V&V head-to-head studies; and (ii) completion of the sale and lease back of the newly constructed BioCampus facility.
  • Verification & Validation (“V&V”) “head-to-head” data exceeds target concordance for blood grouping
  • Overall concordance for antigen typing – 99.8%, demonstrating robustness of the MosaiQ platform
  • Completion of the BioCampus sale and leaseback transaction

“Further optimization of the MosaiQ microarray manufacturing process was successfully undertaken in January, designed to improve the robustness of the MosaiQ blood grouping microarray.  We are pleased to report that concordance data for the subsequent V&V head-to-head studies demonstrates continued strong performance across all antigen typing and antibody detection assays, with overall concordance of 99.8% and 99.1% respectively. I congratulate the Quotient team for achieving this milestone for the MosaiQ platform,” said Franz Walt, Interim Chief Executive Officer of Quotient. “Results of the head-to-head studies are a key element of the V&V studies, completion of which represents one of the final steps prior to commencing field trials for the initial MosaiQ blood grouping microarray.”

Assay Performance

Results of the V&V head-to-head studies for the MosaiQ IH Microarray (the initial blood grouping microarray) indicate that MosaiQ achieved the required targeted performance compared with predicate technologies for all assays. The V&V data were derived in accordance with established protocols using microarrays manufactured in Quotient’s validated, high-volume manufacturing facility and run on field trial-ready instruments.

MosaiQ IH Microarray - Antigen Typing

A summary of the V&V head-to-head study results for antigen typing compared with the predicate technology is set out below:

Blood Group Antigen A B D C c E e Cw K k
Concordance 100.0% 100.0% 99.3% 100.0% 99.2% 100% 99.6% 100.0% 100.0% 99.8%

The above results imply overall concordance of 99.8% for MosaiQ.  In this study 1,282 donor samples were tested and the results compared with predicate technologies, except for little-k where 157 MosaiQ test results were confirmed manually and Cw where 592 MosaiQ test results were confirmed manually.

MosaiQ IH Microarray - Antibody Detection

The V&V head-to-head study for antibody detection achieved 99.1% concordance compared with the predicate technology.  In this study 1,255 donor samples were tested.

Completion of BioCampus Sale and Leaseback

On February 20, 2018 Quotient announced it had entered into definitive agreements for the sale and leaseback of its recently completed BioCampus facility located near Edinburgh, Scotland.  This sale and leaseback transaction was completed on March 23, 2018.

Upcoming Regulatory and Commercial Milestones

  • European Field Trials – Quotient expects to commence European field trials shortly
  • European Regulatory Approval – Upon the successful completion of European field trials Quotient expects to file promptly for European regulatory approval for the MosaiQ IH Microarray
  • European Commercialization – Quotient will facilitate internal validation of MosaiQ by key target European customers following completion of the European field trial, prior to entering formal contract discussions
  • U.S. Field Trials – Quotient expects U.S. field trials for the MosaiQ IH2 Microarray (incorporating a more comprehensive antigen typing menu) to follow the successful completion of European field trials for the MosaiQ IH Microarray later in CY18, with US and European Regulatory submissions following thereafter 

MosaiQ Platform

MosaiQ, Quotient's next-generation platform is designed to deliver fast, comprehensive antigen typing, antibody detection and disease screening results, using a single low volume sample in a high throughput automated format.
