Integral Molecular Launches TiterSafe™ Influenza Virus-Like Particles for Safe and Convenient Vaccine Testing
Non-infectious TiterSafe particles can be used as a virus substitute in hemagglutination inhibition (HAI) assays to test influenza vaccine efficacy.
Non-infectious TiterSafe particles can be used as a virus substitute in hemagglutination inhibition (HAI) assays to test influenza vaccine efficacy.

Philadelphia – Integral Molecular, a leading provider of reagents for vaccine evaluation, announces the launch of TiterSafe™ influenza virus-like particles, an off-the-shelf virus-alternative for key experiments in testing influenza vaccines. Titersafe is a safe and convenient substitute for live virus that is ready for immediate use, reduces biosafety hazards for lab workers, and is well-suited for high-throughput assays. In contrast, traditional assays require the difficult preparation of live influenza virus, potentially expose researchers to infection, and need dedicated containment facilities for pandemic virus strains.

TiterSafe particles mimic the architecture of live virus, featuring surface influenza proteins hemagglutinin (HA) and neuraminidase (NA) along with an interior protein core. Crucially, they lack DNA or RNA components that enable virus replication. The HA protein on TiterSafe particles behaves identically to HA on live virus in experiments, sticking to red blood cells and causing them to clump, or “hemagglutinate”. Inhibition of this clumping by anti-HA antibodies in serum (an “HAI assay”) is the standard FDA-accepted method for influenza vaccine assessment. TiterSafe comes in assay-ready portions for immediate use in HAI assays and is available with HA and NA variants to match seasonal strains of influenza.

“For over 20 years we have responded to viral threats including SARS-CoV-2, dengue, Zika, and now influenza by developing products that allow any lab to work safely with viruses,” said Kyle Doolan, Director of R&D at Integral Molecular. “While the FDA-accepted HAI assay is relatively easy to perform, scaling up reagents and working with highly infectious live viruses requires considerable time and resources. We are pleased to offer this off-the-shelf reagent that will enable vaccine developers to focus their time on more pressing research.”

TiterSafe is currently available for seasonal and pandemic influenza strains. Additional products will be released as new strains are announced.

Integral Molecular Unveils Trispecific Molecules Targeting GPRC5D, BCMA, and CD3 for Multiple Myeloma

Philadelphia – Integral Molecular, a leading biotech company specializing in antibody discovery against undruggable protein targets will present multispecific molecules targeting GPRC5D, BCMA, and CD3 this week during the Society for Immunotherapy of Cancer (SITC) conference in San Diego.

Recent clinical data demonstrate that combination therapy of T cell engaging molecules individually targeting GPRC5D and BCMA on tumor cells offers unprecedented therapeutic benefits in relapsed/refractory multiple myeloma patients. A trispecific antibody that simultaneously engages these molecules while activating T cells is expected to provide comparable and additional benefits as a monotherapy.

Integral Molecular’s oncology drug discovery program has yielded a panel of high affinity bispecific and trispecific molecules targeting GPRC5D, a GPCR target with complex structural biology. The molecules show picomolar cell-killing activity and are highly selective for their targets.

“For decades we have navigated the complexities of molecules like GPRC5D, successfully discovering antibodies against even the most challenging targets,” said Joseph Rucker, PhD, VP of R&D at Integral Molecular. “In just a few short months we were able to simultaneously target GPRC5D and BCMA, and we expect to rapidly advance this molecule into preclinical studies.”

The company leveraged its MPS antibody discovery platform to discover and engineer antibodies for this program. MPS is unique from other platforms in the use of RNA, DNA, and virus-like particles (VLPs, or Lipoparticles) to present properly folded membrane proteins, and the use of divergent species (chickens) to generate diverse antibody responses.

Dr. Rucker will present the company’s bi- and trispecific GPRC5D antibodies in a poster during the SITC 2023 conference. GPRC5D and other antibody assets from Integral Molecular are available for licensing.

Integral Molecular Secures Nearly $900K in NIH Funding to Discover Antibodies Against Difficult and Conserved Protein Targets

PHILADELPHIA–Integral Molecular, a leading biotech company specializing in antibody discovery against challenging protein targets, announces that it has been awarded NIH funding totaling $896,000. The NIH has identified 230 GPCRs and ion channels as underexplored targets with potential to impact human health as part of its project, Illuminating the Druggable Genome. Funding awarded by NIH enables Integral Molecular to discover antibodies against many of these targets. To enable better models of human disease, Integral Molecular has also received NIH funding to discover antibodies that target highly conserved proteins across species.

Integral Molecular will employ its MPS antibody discovery platform to discover antibodies for both initiatives. This platform is tailored to deliver molecules against difficult and conserved targets such as GPCRs and ion channels that are valuable drug targets. Integral Molecular’s strategy of generating antibodies in chickens is key for producing antibodies against conserved targets, a feat not easily achieved with conventional technologies. What additionally sets MPS apart from other platforms is the use of RNA and virus-like particles (VLPs, or Lipoparticles) for presenting properly folded membrane proteins to generate robust responses.

“With our decades-long experience studying complex proteins and an antibody success rate exceeding 95%, we are confident in delivering the desired molecules,” stated Ross Chambers, PhD, Vice President of Antibody Discovery at Integral Molecular. “Our isolation of antibodies reactive with diverse species will help reduce the use of non-human primates in research.”

A Shot in the Arm for Flu Research: Integral Molecular Introduces Off-the-Shelf Reagents to Evaluate 2023/2024 Influenza Vaccine Efficacy

PHILADELPHIA–Integral Molecular, a leader in providing safe, off-the-shelf Reporter Virus Particles (RVPs) to study vaccine efficacy, has expanded its extensive portfolio with RVPs for influenza strains recently recommended by WHO for 2023/2024 seasonal influenza vaccines. These RVPs offer researchers a ready-to-use reagent to reliably test vaccinee serum for influenza neutralization, providing an alternative to the standard assay method requiring laborious preparation of live viruses in cells or eggs.

RVPs are “pseudoviruses” lacking viral components that enable replication, and so are safe under standard (BSL2) laboratory conditions, unlike many viruses or pandemic strains that require restrictive and limited (BSL4) facilities. RVPs display a quantitative and reproducible readout, enabling simple virus infectivity neutralization assays.

Integral Molecular has 20+ years’ experience in RVP production, and all of the company’s RVPs are extensively quality-controlled and validated. With excellent reproducibility and ease of use, RVPs are commonly used as critical reagents for high-throughput testing of hundreds or thousands of samples in vaccine efficacy trials.

“Our experience supplying the industry with RVPs reflecting the rapidly mutating SARS-CoV-2 virus enhanced our ability to quickly respond to evolving viral threats,” said Kyle Doolan, PhD, Director of Research at Integral Molecular. “Our ability to generate a panel of Influenza RVPs so quickly after the WHO announcement, again demonstrates our ability to respond rapidly with research tools that alleviate the burden of producing ‘live’ viruses.”

Integral Molecular’s seasonal Influenza RVPs represent specific strains for influenza A H1N1 and H3N2 and influenza B. Integral Molecular also offers a broad range of RVPs for other influenza strains including A H5N1 and H7N9, along with RVPs for an extensive selection of SARS-CoV-2 variants, and dengue, Zika, chikungunya, Ebola, and Nipah viruses.

Genetic Engineering and Integral Molecular Present – Specificity Testing of Antibody and CAR-T Cell Therapies for IND Using the Membrane Proteome Array

 

Thursday, June 22, 2023
Watch the webinar

Rigorous specificity analysis is critical for successful drug development and a safety requirement for antibody-based therapies, such as CAR-T, entering IND. Tissue cross-reactivity (TCR) studies have been traditionally used to screen for off-target binding; however, their predictive value for in vivo safety and toxicity is poor. Integral Molecular has developed the Membrane Proteome Array (MPA) platform to de-risk antibody-based therapeutics by testing specificity across the full human membrane proteome expressed in live cells. Using sensitive high-throughput flow cytometry to identify binding interactions on a protein level, this technology has emerged as the leading solution for antibody specificity profiling.

In this GEN webinar, our panelists will discuss their experiences using the MPA to rapidly identify potential off-target interactions, resulting in successful IND filings for CAR-T cell therapies where conventional approaches did not suffice. We will also describe the newest additions to this 6,000-protein cell array and the status of its consideration by the FDA as a qualified Drug Development Tool.

With a focus on specificity screening, this webinar assembles experts in antibody discovery and development and features presentations from Integral Molecular, Cabaletta Bio, and The University of Pennsylvania.

  • Understand how Integral Molecular’s MPA is used to identify potential off-target binding liabilities
  • Learn how MPA data supports IND submissions with advantages over traditional tissue cross-reactivity studies
  • Discover how the MPA was used to rapidly evaluate the specificity of novel CAR-T cell therapies for autoimmunity and cancer
