Dr. Kartik Chandran and Dr. Liise-anne Pirofski give 2024 Montefiore-Einstein Presidential Lecture

Einstein scientists Kartik Chandran, Ph.D., and Liise-anne Pirofski, M.D., were the honored speakers at Einstein’s fifth Presidential Lecture.

Einstein scientists Kartik Chandran, Ph.D., and Liise-anne Pirofski, M.D., discussed their research advances on SARS-CoV-2 and other emerging viruses during the fifth Presidential Lecture, held Wednesday, Sept. 25, in Robbins Auditorium. The annual lecture series was established to spotlight the outstanding research conducted at Albert Einstein College of Medicine and Montefiore Health System.

This year’s honored speakers worked on two urgent missions during the height of the COVID-19 pandemic: Dr. Pirofski described her studies of convalescent plasma, which was taken from people who had recovered from the infection and was then transfused into hospitalized patients; Dr. Chandran described his group’s work with emerging viruses—including SARS-CoV-2—aimed at preparing for and responding to new epidemics and pandemics.

Pamela Stanley, Ph.D., professor of cell biology and chair of the faculty interactions committee that selected this year’s featured speakers, introduced Philip O. Ozuah, M.D., Ph.D., president and CEO of Montefiore Einstein, and Yaron Tomer, M.D., the Marilyn and Stanley M. Katz Dean of Einstein and chief academic officer at Montefiore Einstein, who each delivered welcoming remarks.

PROVIDENT goes live!

The ReVAMPP network will support monoclonal antibody and vaccine research on pathogens from many different groups of viruses, including those shown here: hantavirus, yellow fever virus, Nipah virus, picornavirus, and Chikungunya. NIAID

Albert Einstein College of Medicine has received a five-year, $14 million per year grant from the National Institute of Allergy and Infectious Diseases (NIAID) to participate in a broad national effort to develop "plug-and-play" vaccines and antibody-based therapies against a wide range of emerging viruses. The grant is part of NIAID’s new Research and Development of Vaccines and Monoclonal Antibodies for Pandemic Preparedness (ReVAMPP) Network, which was announced earlier today.

“COVID-19 taught us a lot about pandemic preparedness, and we want to make sure we build on what worked well,” said Kartik Chandran, Ph.D., the principal investigator on the grant and professor of microbiology & immunology, the Gertrude and David Feinson Chair in Medicine, and the Harold and Muriel Block Faculty Scholar in Virology at Einstein. “One of the key lessons from the COVID pandemic is that having existing research on a viral family allows scientists to develop vaccines and therapeutics for a particular virus much more quickly. In our project, we plan to create a base of critical knowledge about groups of similar viruses and then—should a related “virus X” pose a health threat—develop specific countermeasures as quickly as possible to save as many lives as possible.”

The Einstein-led consortium, called PROVIDENT (Prepositioning Optimized Strategies for Vaccines and Immunotherapeutics Against Diverse Emerging Infectious Threats), will link 13 teams in academia, government, and industry that will conduct four projects designed to:

  • Discover and analyze virus-host interactions and the molecular mechanisms involved in viral disease;

  • Design proteins to elicit antiviral immune responses and then evaluate and optimize those responses;

  • Create “road maps” for quickly developing RNA vaccines against microbes with pandemic potential; and

  • Map the antibody responses observed in people infected with viruses and use this knowledge to design vaccines and therapeutics.

PROVIDENT builds on NIAID’s 2021 Pandemic Preparedness Plan, a sweeping federal program designed to address the uncertainties inherent in safeguarding global health from communicable diseases. The two-part plan focuses on “priority pathogens” and “prototype pathogens”—basically, the knowns and unknowns of the viral world. Priority pathogens include viruses that are known to cause significant human illness or death, such as dengue virus and Ebola virus.

Prototype pathogens—the focus of PROVIDENT—are representative viruses in families that have the potential to cause significant human disease. “We plan to select and study one or two prototype viruses from each family and then develop countermeasures that will work against as many viruses within that family as possible,” said Dr. Chandran. “That strategy of quickly responding to an emerging virus with an approach and tools that have already been developed is what we mean by ‘plug and play’.” A part of PROVIDENT’s strategy will be to carry out “sprints” in which countermeasures that are developed for the prototype pathogens will be tested against other viruses in the same family to see how well they work and to improve them.

PROVIDENT will concentrate on three virus families: nairoviruses, transmitted by ticks (e.g., Crimean-Congo hemorrhagic fever virus), hantaviruses, borne by rodents and other small mammals (e.g., Sin Nombre virus and other agents causing hantavirus pulmonary syndrome), and paramyxoviruses, borne by bats and other mammals, including domesticated animals (e.g., Nipah virus).

“This approach allowed researchers to move quickly during the COVID-19 pandemic,” said Dr. Chandran. “What we had learned from previous outbreaks caused by coronaviruses, including SARS [severe acute respiratory syndrome] in 2002 and MERS [Middle Eastern respiratory syndrome] a decade later, helped us create diagnostics, vaccines, and therapeutics against SARS-CoV-2, the virus that causes COVID-19.”

“Recent outbreaks of mpox, Nipah virus, and Eastern equine encephalitis, among other viral infections, underscore the need for an even broader preparedness program,” said Eva Mittler, Ph.D., research assistant professor at Einstein and leader of one of the PROVIDENT components. “We don't know what virus will cause the next pandemic.”

“The overarching goal of PROVIDENT and the other centers in the ReVAMPP Network is to coordinate their efforts to increase our odds of mounting a timely and effective response,” added Dr. Chandran.

Developing a Broad-Spectrum Ebola Treatment

Einstein Magazine profiles our work on the development of a broadly active human antibody therapeutic cocktail against Ebola virus and related agents in their feature entitled “Translating Discoveries Into Therapies.” This cocktail is being developed by our biotech partner Mapp Bio with support from the US Biomedical Advanced Research and Development Authority (BARDA).

Human Antibody Broadly Protects Against Hantavirus Infection

Read our paper in Science Translational Medicine describing our work on the isolation of human monoclonal antibodies against the glycoprotein spikes of rodent-borne hantaviruses associated with severe human disease in Northern Europe. Our investigations led us to a single antibody that is a promising candidate for clinical development as a broad countermeasure against hantaviruses. The way this antibody binds to the hantavirus spike also informs the development of broadly protective hantavirus vaccines.

This work was the product of our NIH-funded international consortium, Prometheus, whose goal is to to develop antibody-based therapies against hantaviruses and other highly lethal viruses for which there are no approved vaccines or treatments.

Improving Triage for COVID-19 Patients by Predicting the Timing of Clinical Outcomes

Read our paper in PLoS Pathogens describing our work to develop a computational model that uses immunological and standard clinical biomarkers to predict patient outcomes. We found that data collected during hospitalization—including spike-protein antibody levels as well as white blood cell, neutrophil, and lymphocyte counts—more accurately predicted whether or not COVID-19 patients would live or die.

Yellow Fever Vaccine’s Potency Against South American Viral Strains

Read our paper in Cell Host & Microbe describing our work on the the human antibody response induced by the widely used yellow fever vaccine.

Yellow fever is a mosquito-borne viral infection with no known treatment that affects some 200,000 people each year in Africa and South America. The disease has been surging in recent years, including an epidemic in Brazil in 2017-19 that was the largest outbreak in 70 years. Current yellow fever vaccines are based on a virulent African strain of the virus and considered to be equally effective against all yellow fever variants, including the emerging Brazilian strain.

In this paper, we report that the yellow fever vaccine has reduced activity against the recent Brazilian strain. Similar to what we have seen with the COVID-19 variants of concern, we show that the Brazilian strain (and most other South American strains) have undergone key amino acid changes that make them less susceptible to vaccine-induced neutralization. Our research provides a roadmap to improve assessments of the antiviral antibody response in South American vaccines and for developing next-generation yellow fever vaccines.

Confronting the COVID-19 Crisis

When COVID-19 came to NYC in the spring of 2020, most labs at Einstein were shut down, but we were allowed to keep working with half of our team, under the condition that we switched our entire program to the emergency COVID response. Thus, the ‘COVID Crew’ was born. Pretty soon, we were busier than we could ever have imagined …

Einstein Magazine features our work to ‘spike the coronavirus’ during those early, traumatic days of COVID-19.

PhD and MD/PhD students in our lab were key players in our response and their efforts are profiled in the same issue.

One year into the pandemic, I spoke with our Dean, Dr. Gordon Tomaselli, and my amazing colleagues at Einstein and Montefiore, Drs. Liise-anne Pirofski and Michelle Gong, about our involvement in the COVID-19 response at our institution, our experiences, and what we thought was to come.

New $22 Million Project Targets Deadly Viruses

April 3, 2019—(BRONX, N.Y.)—The National Institute of Allergy and Infectious Diseases (NIAID) has awarded an international consortium led by Albert Einstein College of Medicine a five-year, $22 million grant to develop antibody-based therapies against four highly lethal viruses for which there are no approved vaccines or treatments.

The viruses are the tick-borne Crimean-Congo hemorrhagic fever virus (CCHFV) and three hantaviruses, which are spread by rodents: Andes virus (ANDV), Sin Nombre virus (SNV), and Puumala virus (PUUV). The NIAID has designated all but PUUV as Category A agents—emerging infectious diseases or pathogens that pose the highest risk to national security and public health.

The project, called the Prometheus Center for Excellence in Translational Research (Prometheus), focuses on viruses that spread from animals to people. It builds on a 2017 study involving ebolaviruses, believed to spread to people from fruit bats or primates. In addition to Einstein, the participating institutions leading the project are the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID), Mapp Biopharmaceutical, Inc., The University of Texas at Austin, and Adimab, LLC, a biotech company.

Einstein Responds to the Urgent Need for Effective Ebola Treatments

kartik-chandran-effective-ebola-treatments.jpg

Our back-to-back papers in Cell Host & Microbe describe the development of an antibody cocktail that can protect animals against all three ebolaviruses associated with human disease outbreaks. This cocktail, MBP134, has set new benchmarks in both antiviral breadth and therapeutic efficacy.

Our industrial partner, Mapp Biopharmaceutical, is developing MBP134 for human use in collaboration with the U.S. Biomedical Advanced Research and Development Authority (BARDA). in rodent and large-animal models of lethal ebolavirus disease.

This work represents the efforts of an amazing international consortium of scientists from academia, government, and industry, including Einstein, Mapp Biopharmaceutical, Adimab LLC, Public Health Agency of Canada, United States Army Medical Institute of Infectious Diseases (USAMRIID), University of Texas-Medical Branch, and Massachusetts General Hospital. Stay tuned for more exciting work from our posse!

Go here for my Q&A about our findings and their importance for developing a broadly protective therapy against ebolavirus disease.

Study Identifies How Hantaviruses Infect Lung Cells

Check out highlights of our work to discover a new receptor for hantaviruses that cause severe pulmonary syndrome (HPS) in the New World on the Einstein and NIH websites. We believe that this receptor could provide a target for the development of therapeutics to protect against HPS.

This study is a great example of the power of dispersed collaborative teams to do interdisciplinary science. The Chandran Lab’s Rohit Jangra and other lab members drove these efforts, but other labs from three continents also played key roles. Thank you to John Dye, Zhongde Wang, Thijn Brummelkamp, Jason Moffat, Félix Rey, Nicole Tischler, Dev Sidhu, and Jon Lai and all of their participating group members for making this happen.

Listen to Rohit and me discuss our new discovery on the This Week in Virology (TWiV) podcast with Dr. Vincent Racaniello and colleagues.

Read about how our NIAID-funded study could lead to broad, versatile treatments for many different Ebolaviruses.

Researchers funded in part by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), have studied the blood of an Ebola survivor, searching for human antibodies that might effectively treat not only people infected with Ebola virus, but those infected with related viruses as well. Now the researchers have identified two such antibodies that hold promise as Ebola treatments.

How to turn competitors into collaborators

Commentary in Nature highlights the power of cross-institutional collaborations and lessons learned by the team as they make headway on finding better treatments for Ebola virus infection. The Chandran Lab is an integral part of the Viral Hemorrhagic Fever Immunotherapeutic Consortium, contributing key functional assays that characterize neutralization activity of monoclonal antibodies and help predict their therapeutic potential.
