During this year's AAPS National biotechnology conference, Navigate BioPharma Services, Inc., a Novartis subsidiary and a leading provider of innovative biomarker solutions for drug development, announced the launch of its new multiplex digital PCR assays for comprehensive quantification of multiple chimeric antigen receptor (CAR) T cells, a type of cancer immunotherapy that involves genetically modifying T cells to recognize and destroy certain cancers. These assays are based on the Qiagen QIAcuity digital PCR System, which offers a powerful yet easy-to-use digital PCR experience through its unique nanoplate system.
The new multiplex digital PCR assay enables simultaneous measurement of the number, function and persistence of CAR-T cells in clinical blood and bone marrow samples, without the need for a standard curve. It can detect as low as 0.01% of CAR-T cells among normal T cells, with a turnaround time of less than two hours. These assays can measure up to five different CAR-T cell markers in a single reaction, using specific probes for different CAR targets, to quantitate multiple CAR-domains, or combinations of commonly used therapeutic targets for CAR-T therapies. The assay can help clinicians monitor response or safety events during clinical trials to enable the development of new therapies.
"CAR-T therapy is a promising and innovative approach to treat cancer, but it requires accurate and reliable quantification of CAR-T cells for successful drug development," said Dr. Nathan Riccitelli, Associate Director of Innovative Technologies at Navigate BioPharma Services, Inc. "Our new proprietary multiplex digital PCR assay provides a comprehensive and robust solution for measuring CAR-T cells in clinical samples with high sensitivity, specificity and reproducibility."
Navigate BioPharma Services, Inc. has developed this assay for use in sponsors-led clinical trials. If interested, contact them about how this assay can be used in upcoming clinical trial studies.

Mission Bio, Inc., the pioneer in high-throughput single-cell DNA and multi-omics analysis, announced breakthrough improvements to the Tapestri® Platform and its core chemistry that enable highly confident detection of rare cells for a range of applications. With Tapestri® v3 chemistry, researchers can discover tiny numbers of single cells that, until now, easily escaped detection and influenced disease in invisible ways. At the same time, drug developers can use the new capabilities for a more complete understanding of their advanced therapies, potentially leading to safer, more effective medicines.
The new Tapestri® v3 chemistry increases the number of cells captured per sample by up to four times compared to the prior chemistry, a notable enhancement. With enhanced cell capture, the Tapestri® Platform can more reliably detect rare cells, opening incredible new possibilities like improving the assessment of measurable residual disease (MRD), a key metric used increasingly in clinical settings to estimate the risk of relapse with certain cancers.
In the case of MRD in hematological cancers, rare subclonal variants are commonly missed by bulk NGS due to its averaging effect, hindering the detection of relapse-driving clones that potentially offer new therapeutic targets. With Tapestri®'s expanded capabilities, new integrated multi-omics tools like the Tapestri® scMRD Assay for Acute Myeloid Leukemia (AML) will offer clinicians additional therapeutic insights, rather than providing a binary 'yes or no' answer to the presence of residual disease. A team of investigators from Memorial Sloan Kettering Cancer Center (MSK) using the assay has reported a high sensitivity of 0.01% limit of detection in data presented at Mission Bio's Tapestri® scMRD for AML Summit last year.
Tapestri®'s new capabilities also hold promise for cell and gene therapy developers looking to improve quality assessment throughout the therapy development process. Powered by Tapestri® v3 chemistry, the increase in cell throughput means Tapestri® Genome Editing Solution can measure gene editing outcomes at single-cell resolution – even for very low-frequency events like translocations, which can have significant effects on the safety of the therapy.
Tapestri® v3 is the latest example of Mission Bio's continued focus on customer-centric product and service development. The company has recently implemented additional quality control measurements including design and development, release, and documentation processes compliant with the ISO 9001 standard.
"Our customers' success is at the forefront of our mind," said Adam Abate, PhD, Co-founder and Interim Chief Executive Officer of Mission Bio. "Researchers and drug developers are demanding ever-greater sensitivity and highly robust products to effectively progress their research or advanced therapeutic program, and we are committed to serving our customers and helping them achieve their goals."
The new v3 reagents will be available for shipping starting in mid-June.

Guardant Health, Inc. announced that Singapore's Health Sciences Authority has granted regulatory approval of Guardant360® CDx, a liquid biopsy test for tumor mutation profiling, also known as comprehensive genomic profiling in patients with advanced solid cancers. The Guardant360 CDx test was also approved as a companion diagnostic to identify patients with advanced non-small cell lung cancer with epidermal growth factor receptor alterations who may benefit from treatment with TAGRISSO®.
Guardant360 CDx is the first blood test to be approved by Singapore's HSA for comprehensive genomic profiling for all solid tumors. Since being introduced as a laboratory developed test the Guardant360 liquid biopsy has become widely accepted for blood-based CGP with more than 400 peer-reviewed publications.
"We are delighted to receive regulatory approval from HSA for our Guardant360 CDx test, as it supports the value liquid biopsy brings to oncologists and the patients they treat," said Simranjit Singh, CEO of Guardant Health AMEA. "With a simple blood draw from the patient, the Guardant360 CDx test provides CGP results in approximately seven days from receipt of the blood sample in the laboratory, enabling physicians to make faster treatment decisions compared to tissue biopsies. Our hope is that this approval will drive clinical adoption of liquid biopsy testing in Singapore and enable more patients to be matched to potentially life-changing precision medicines."
In 2020, over 23,600 people in Singapore were diagnosed with cancer and there were slightly over 12,000 cancer-related deaths. The most prevalent cancer types among men and women in Singapore include breast (15.5%), colorectal (15.1%) and lung (12.3%) cancer. According to the Singapore Cancer Registry Annual Report 2020, over 70% of all lung cancer cases among men and women were diagnosed at the advanced stage. Pancreatic, stomach and colorectal cancer cases among men and women were also diagnosed at the advanced stage respectively To improve cancer outcomes in Singapore, Guardant Health AMEA is currently collaborating with National Cancer Centre Singapore and National University Cancer Institute, Singapore for several clinical trials using the Guardant360 test in efforts to accelerate clinical trial enrollment by identifying genomic biomarkers in patients with cancer.
The Guardant360 CDx test was the first blood test to be approved by the U.S. Food and Drug Administration (FDA) for comprehensive genomic profiling for all solid tumors, and it is now FDA approved as a companion diagnostic test for four targeted therapies in NSCLC and one in advanced breast cancer. In March 2022, the test was also granted regulatory approval by Japan's Ministry of Health, Labour and Welfare for tumor mutation profiling in patients with advanced solid cancers as well as a companion diagnostic to identify patients with microsatellite instability-high (MSI-High) solid tumors who may benefit from Keytruda® and patients with MSI-High advanced colorectal cancer who may benefit from Opdivo®. In addition, Guardant Health is currently involved in multiple studies with drug development companies to develop Guardant360 CDx as a companion diagnostic for new therapies.
