GLA-SE adjuvant remains stable after four years

Dr. Shan Lu’s laboratory working with the Infectious Disease Research Institute (IDRI) completed another test as part of the stability program for its GLA-SE adjuvant manufactured in 2016. The results show the adjuvant is very stable and can be used in more clinical trials.

PDPHV vaccine candidate was developed in the laboratory of Dr. Shan Lu at the University of Massachusetts Medical School (UMMS). In 2015, using the funding provided by NIAID’s IPCAVD program, IDRI manufactured the adjuvant specifically for PDPHV vaccine as part of the HVTN 124 clinical trial. At the time, a 4-year program was launched to monitor the stability of GLA-SE to support its continued use in the clinical trial. With the pending completion of HVTN124, the 48-month time point stability data review showed no noticeable degradation of the product.

WHV will use the remaining GLA-SE in more WHV planned clinical studies. Accordingly, WHV will work with IDRI to extend the stability study to further monitor the preservation of this adjuvant.

End of the five-year program demonstrates stability of WHV’s DNA vaccine

Dr. Shan Lu’s laboratory working with Waisman Biomanufacturing and Eurofins completed the stability program for its DNA vaccine manufactured in 2015. The results show vaccine is very stable and can be used in clinical trials.

PDPHV vaccine candidate was developed in the laboratory of Dr. Shan Lu at the University of Massachusetts Medical School (UMMS). In 2015, using the funding provided by NIAID’s IPCAVD program, the laboratory manufactured the DNA vaccine to be used in the HVTN 124 clinical trial. At the time, a 5-year program was launched to monitor the stability of the five-valent vaccine to support its continued use in the clinical trial. The program recently ended, and the data review showed no noticeable degradation of the product.

WHV will use the remaining DNA product in its planned Phase 1 study. In parallel, it will extend the stability study to further monitor the preservation of this DNA vaccine.

WHV advances to manufacture 4-valent protein for Phase 2a trial

Working with Waisman Biomanufacturing, WHV demonstrated that protein bulk drug substances manufactured in 2015 remain stable and will advance to formulating them into a 4-valent drug product for the first time.

Recombinant gp120 proteins from HIV-1 clades A, B, C, and AE were manufactured in 2015 at Waisman Biomanufacturing in Madison, WI with support from NIAID’s Integrated Preclinical/Clinical AIDS Vaccine Development (IPCAVD) program. At the time, some of the proteins were vialed individually as Final Drug Product for use in the Phase clinical trial HVTN 124. The trial completed vaccinations in October of 2019 and demonstrated good safety profile (the immunogenicity data are expected in early 2021).

The remaining bulk drug substances have been stored at -70C degree. Now, WHV and Waisman Biomanufacturing tested the proteins and found them to be stable and potent, supporting the decision to formulate the proteins into a Final Drug Product to be used in the planned Phase 2a clinical trial.

For the first time, the proteins will be formulated as a 4-valent mixture, greatly simplifying storage and administration of the vaccine. WHV and Waisman Biomanufacturing already defined release and stability assays to be used to characterize and monitor the 4-valent mixture. The US Food and Drug Administration (FDA) was consulted regarding the proposed plans and provided positive feedback for WHV’s plans.

Mollie Ockene joins WHV as an intern

WHV researchers believe in the need to train the next generation of leaders to tackle health challenges around the world. Thus, it is our great pleasure to announce that Mollie Ockene joined our team as an intern looking to learn more about HIV vaccine development and to assist with a variety of projects at the company.

Mollie is a rising senior from Boston studying Environmental Policy, Global Health, and pre-medical sciences. At Middlebury College in Vermont she gained experience as a volunteer EMT, joined the leadership board of her sailing team, and is the president of Middlebury Nutrition Outreach and Mentorship, a student organization focused on community engagement with local youth. She has also served on the Environmental Advisory Committee and worked as a research assistant for professors there.

Mollie spent last fall in New Zealand sailing on a tall ship, studying climate science and the health impacts of climate change on the local Māori population. Her academic interests focus on the intersection between medicine and social issues, making her particularly interested in our mission of developing a vaccine to prevent HIV infections worldwide.

WHV Advances Toward Filing IND for the Next Clinical Trial

WHV cleared the path toward filing its own IND and hired Target Health to assist with preparing and filing the necessary documents with US FDA.

WHV is preparing to file a new IND for PDPHV, its investigational DNA-prime/protein-boost vaccine.  PDPHV is comprised of five DNA plasmids and four gp120 recombinant proteins and is being tested in a Phase I clinical trial (HVTN 124) as a prime-boost regimen or co-administered in repeated doses, in healthy adult volunteers. Results of the HVTN 124 trial are expected in the next several months. 

The Division of AIDS (DAIDS) of the National Institutes of Allergy and Infectious Diseases (NIAID) holds the current IND for the vaccine candidate and NIAID-supported HVTN is running the Phase I HVTN 124 trial.  DAIDS expressed support for WHV’s plans to file its own IND and will facilitate the process by transferring several key documents to WHV.

Target Health, LLC, a New York-based CRO with many years of regulatory experience, joined the WHV team and will assist in preparing and filing the IND with the US FDA.

WHV advances with an Exploratory Study of Immune Responses in HVTN 124

HVTN approved WHV proposal to conduct an exploratory study to better characterize the immune responses observed in volunteers in the HVTN 124 clinical study testing WHV’s PDPHV vaccine candidate.

HIV Vaccine Trials Network is conducting immunogenicity assays to assess the peak immune responses observed two weeks after the last immunization in the HVTN 124 trial. At the same time, WHV plans to supplement HVTN’s work by conducting its own investigation into the dynamics of immune responses, as well as conducting additional assay to better assess the breadth and potency of antibodies elicited by the PDPHV vaccine candidate. WHV formally applied to HVTN to request the samples from volunteers needed for the study and the request has been approved.

This work will be conducted in collaboration with Dr. Shan Lu’s Laboratory of Nucleic Acid Vaccines (LNAV) at the UMMS in Worcester, MA. Dr. Lu is the co-inventor of the PDPHV vaccine candidate and his laboratory has extensive expertise in assessing immune responses to the DNA/protein vaccines. Another co-inventor, Dr. Shixia Wang, will lead the studies. The results from both the HVTN study and the exploratory study by WHV will be available later this year.

2020 HIV Vaccine Awareness Day

Right now, the world is focused on COVID-19, which already claimed hundreds of thousands of lives and paralyzed the economies of many countries. The low- and medium-income countries are less prepared to deal with the public health and economic challenges associated with the COVID-19 spread. Many of these countries are already struggling with diseases like malaria, tuberculosis, and HIV and will be severely impacted by the additional strain on their healthcare systems.

The pandemic of SARS-CoV-2 virus once again highlights the need to prepare for potential zoonotic infections that my spread around the world, just like HIV did 40 years ago. The worldwide response to HIV pandemic brought together scientists, doctors, advocates, and public health experts, just like COVID-19 pandemic has been met with international response. Indeed, many of the experts now working on COVID-19 have come from the HIV field. They are bringing the experience and the valuable lessons to accelerate the discovery of preventive measures and treatments for COVID-19.

In these challenging times, WHV remains committed to the development of a preventive HIV vaccine to reduce HIV infections around the world. HIV remains a major public health challenge around the world and a safe and effective vaccine is the best way to stop the virus.

WHV researchers are actively working to better understand the immune responses observed in the HVTN 124 trial, to advance our vaccine manufacturing, and to plan further clinical trials of our vaccine candidate.

WHV collaborates with UMMS to conduct preclinical vaccine studies

In preparation for further clinical testing of its PDPHV vaccine candidate, WHV is working closely with Dr. Shan Lu’s Laboratory of Nucleic Acid Vaccines (LNAV) at the University of Massachusetts Medical School to conduct immunogenicity studies of the vaccine in small animal models. The studies will test the immunogenicity of newly manufactured vaccine products for a planned Phase IIa study and help refine the design of the next clinical trials by exploring different vaccine formulation, dosing, and administration schedules.

Phase I clinical study HVTN 124 is testing safety and immunogenicity of WHV’s DNA-prime/protein-boost vaccine candidate PDPHV in healthy volunteers. The results of the trial will be available later this year, but WHV is already planning the next steps in its clinical program. Additional questions about vaccine formulation, dosing, and schedule will be answered in the follow-up clinical trials.

Testing in small animal models can be extremely helpful in down-selecting among many potential avenues of vaccine improvement. Because the PDPHV vaccine candidate has been developed at LNAV, the researchers there, including Drs. Shan Lu and Shixia Wang have extensive expertise in assessing immunogenicity of this vaccine in preclinical models. Several animal studies are being conducted to investigate immune responses to the current vaccine candidate, to help better interpret the expected results of the current HVTN 124 trial, and to bridge the findings to future clinical trials.
