The Branford, Connecticut-based company said that it will use the funds to commercialize its IsoLight platform for use in quality control and guidance of CAR T therapy.

IsoPlexis Closes $25M Series C Round

“We are pleased to lead the financing of IsoPlexis, an emerging leader in single cell analysis, which is catalyzing research in immunotherapy as well as a number of other high value applications,” Chris MacGriff of Northpond Ventures said in a statement.


MD Anderson, IsoPlexis Link T-Cell Functionality to Immunotherapy Response in AML

In work presented at the recent American Association for Cancer Research annual meeting, they found that T-cell cytokine production predicted patient response.


Improving Preclinical Discovery of CRISPR Engineered Immune Cell Therapies

There is an urgent need to characterize the potency and efficacy of CRISPR-Cas9-modified inducible pluripotent stem cell-derived natural killer cells for preclinical cancer immunotherapy research. IsoPlexis’ single-cell proteomics system addresses this challenge by connecting each immune cell to cytokine secretion and thereby correlating them to in vivo outcome across a range of disease areas.


Q&A: Evolution of CAR-T Cell Therapy and Future Directions

James Heath, PhD., is president and professor at the Institute for Systems Biology in Seattle. He also has the position of Professor of Molecular and Medical Pharmacology at UCLA, and he has directed the NCI-funded NSB Cancer Center since 2005. GEN recently spoke with him on current issues and future trends regarding CAR T-cell therapeutics.


The Polyfunctional Strength Index: From Concept to Solution

Unlike a small molecule or antibody that always has the same structure, each time an autologous cell therapy is developed the starting material comes from a different patient, making it virtually impossible to reproducibly develop an identical “drug”. Having the ability to drive better outcomes by profiling the complete function of each cell would be a significant advantage for bioengineers—a challenge the IsoPlexis single-cell proteomic system has been designed to address.


The Power of PSI in Evaluating CAR-T Therapy

Researchers and clinicians urgently need new approaches to understand the functional profile of cell therapy products to accelerate discovery and development, to achieve manufacturing consistency, and to predict which patients will derive the most value from these drugs while minimizing side-effects. IsoPlexis’ Polyfunctional Strength Index (PSI™) can be utilized to address these challenges, in particular to provide metrics that uniquely relate the CAR-T cell product response to in vivo preclinical and clinical outcome measures.


Signs, Portents, and Immuno-Oncology Biomarkers

Single-cell suspensions don’t present spatial context like needle biopsies do, but the cytokines each individual cell produces still tell a compelling story. For example, cytokine secretion profiles correlate with, and can help predict, clinical outcomes in immunotherapy, said Will Singleterry, PhD, director of business development at IsoPlexis. To back this assertion, he presented data from the company’s many collaborations.


Quality and Polyfunctionality in Cell Therapy Development Can Broaden Therapeutic Options

There are no currently well-defined methods to predict or characterize adverse effects, such as severe cytokine release syndrome (CRS) or neurotoxicity. Although circulating cytokine levels in blood are monitored, often that is too late, and drugs, such as IL-6, cannot prevent the patient’s death. In addition, the CAR T-cell infusion product may contain some cells with bizarre functions. IsoPlexis’ technology can comprehensively evaluate the cells with almost no bias, so you get a full portrait of the whole infusion product, even small subsets of the cells with bizarre functions.


Optimizing Immunotherapy Lead Selection

An urgent need exists for novel detection strategies to better understand mechanistic function and efficacy at the single-cell level in a way that correlates to clinical outcomes. Population level studies do not provide the necessary insight into immune response heterogeneity at the single-cell level. IsoPlexis’ single-cell proteomics systems address this challenge by connecting each immune cell to the many cytokines they secrete, which orchestrate the immune system.


IsoPlexis has been Recognized with Pharma Tech Outlook’s Cover Story for the Top 10 Analytics Solution Providers in 2018

The award focuses on IsoPlexis’ IsoSpeak software suite’s ability to clarify results, reports, and associations from large, complex patient data sets, thereby delivering leading biopharma and clinical researchers better data by which to determine effective cancer immunotherapies.


IsoPlexis Uses Single-Cell Platform to Assess T Cell Activity in CAR-T Cancer Therapy

The work was part of a larger study looking at the effectiveness of ACT in combination with the cytokine agonist NKTR-214. The study, led by Antoni Ribas, director of the tumor immunology program at UCLA’s Jonsson Comprehensive Cancer Center, found that the ACT-NKTR-214 combination improved the induction of cytotoxic T cells and increased their polyfunctionality, indicating that addition of NKTR-214 could boost the performance of ACT. NKTR-214 is produced by San Francisco-based biopharma company Nektar Therapeutics, which also participated in the study. “The finding in a preclinical model that the IsoPlexis assay can detect a remarkable increase in polyfunctionality in tumor-infiltrating lymphocytes recovered from tumors of mice treated with NKTR-214 compared to IL-2 is the most conclusive data we have obtained in this model system,” said Ribas.


IsoPlexis Takes on Cancer, One Cell at a Time

As IsoPlexis prepares to take its production to the next level in 2018, two science news publications have honored the company for technology that tailors optimum treatments for cancer patients. The Scientist magazine named the company’s IsoCode chip and IsoLight platform, an all-in-one system that reads the individual cells of tumors, as the Top Innovation of 2017. One week later, FierceBiotech named the same system the 2017 Fierce Innovation Award for Technology Innovation.


The Power of ‘Poly’ in CAR-T

Research recently published in the journal Blood — conducted in a collaborative effort with Kite Pharma, a Gilead company — demonstrates a significant association between the functionality of an anti-CD19 CAR-T cell product before treatment, as defined by IsoPlexis’ Polyfunctional Strength Index (PSI), and the objective response in patients with non-Hodgkin lymphoma (NHL). “The results highlight the potential to predict whether cancer patients will respond to CAR-T cell therapy before treatment, as well as to improve both pre-infusion product potency testing and guide cell product optimization.”


IsoPlexis Wins 2017 Fierce Technology Innovation Award

The Life Sciences Innovation Report showcases outstanding innovation that is driving improvements and transforming the industry. “Our ability to measure a lot more functional data per individual patient immune cell has provided a pathway to understanding how immunotherapy works, said Sean Mackay, Co-Founder and CEO of IsoPlexis. Mackay said there are three elements that make IsoPlexis  fierce; its thought leadership in technology that stems from the company’s scientific founders and advisory board; a very strong technology platform; and its employees. “All of those elements allow us to maintain our ferocity.”


The Scientist Names IsoPlexis Technology The Top Innovation of 2017

This new single-cell technology allows researchers to characterize cells based on the proteins they secrete—as many as 42 different cytokines, chemokines, and other molecule types at once. “The IsoLight single-cell technology, with its ease-of-use, has the potential to impact cancer research for both biomarker discovery and patient monitoring.”


In Branford, Finding Precision In Cancer Treatments

A Branford life sciences company is working to take the guesswork out of cancer treatments with technology that may predict how patients will respond to drugs before being exposed to them. IsoPlexis is developing a system that analyzes patients’ tumors cell by cell to determine how effective or toxic a treatment would be and to help guide doctors’ decisions about mixing different cancer therapies.


IsoPlexis, a Branford medical technology company, developed some highly advanced hardware and software that allows oncologists to essentially read the information inside a cancer patient’s cells to see whether they would react well to immunotherapies

That means before treating a patient, doctors would be able to tell whether the immunotherapy would be effective and whether it would cause unpleasant side effects.
