Alopexx, Inc. today announced a collaboration with India-based Bharat Biotech for the co-development and commercialization of the broad-spectrum antimicrobial vaccine, AV0328.
AV0328 is a synthetic vaccine designed to target poly N-acetyl glucosamine (PNAG), a substance found on the surface of a wide range of bacterial, fungal, and parasitic pathogens.
In preclinical studies, targeting PNAG has shown effectiveness in preventing and treating infections caused by over 15 different pathogens.
A phase I, first-in-human clinical trial, has been completed, demonstrating that AV0328 is well-tolerated with no serious adverse events observed. The vaccine-induced antibodies are capable of killing a wide range of PNAG-expressing pathogens, reaffirming their potential as a broad-spectrum antimicrobial solution.
Dr. Krishna Ella, Executive Chairman of Bharat Biotech, commented in a press release on September 11, "024: We are proud to collaborate with Alopexx to bring AV0328 to the regions (India) where it is most needed."
"Our goal is to develop solutions to reduce antimicrobial resistance through vaccination. This collaboration aligns with our mission to provide safe, affordable, and high-quality vaccines to combat infectious diseases globally."
The companies will co-develop and commercialize AV0328 in India and other licensed territories as part of the collaboration.
This Review discusses evidence that vaccines can play a major role in fighting antimicrobial resistance (AMR).
Different health organizations have highlighted the emergence and spread of AMR as a global threat. Pathogens resistant to AMR cause substantial morbidity and death. As resistance to multiple drugs increases, novel and effective therapies and prevention strategies are needed, wrote researchers in 2022.
Merck today announced positive top-line results from its pivotal Phase 3 clinical trial evaluating the company’s 9-valent Human Papillomavirus (HPV) vaccine, GARDASIL ® 9 vaccine, in Japanese males ages 16 to 26.
This trial (V503-064) met its primary and secondary endpoints demonstrating that administration of a 3-dose regimen of GARDASIL 9 reduced the combined incidence of anogenital persistent infection caused by nine types of HPV compared with a placebo.
“A decade after the first approval of GARDASIL 9, Merck continues to evaluate this important vaccine in additional patient populations and remains committed to helping prevent certain HPV-related cancers through broad and equitable access globally,” said Dr. Eliav Barr, senior vice president, head of global clinical development and chief medical officer, Merck Research Laboratories, in a press release on September 11, 2024.
“These data build on the clinical efficacy of GARDASIL 9 for the prevention of persistent infection in males and can potentially make a significant impact in addressing the global burden of certain HPV-related cancers and diseases.”
This HPV vaccine is generally available at clinics and pharmacies in the U.S. However, Merck says the GARDASIL 9 vaccination may not protect all vaccine recipients.
The Los Angeles County Department of Public Health (LACDPH) recently confirmed a locally acquired case of dengue fever in a person living in the City of Baldwin Park.
Dengue fever is transmitted primarily through the bite of infected Aedes mosquitoes.
As of September 9, 2024, this is the third locally acquired case of dengue fever in California and the first identified by the Los Angeles County Department of Public Health. Previous locally acquired cases of dengue fever in the greater LA area were identified in Long Beach and Pasadena in 2023.
The LACDPH stated the risk of transmission of dengue virus to the general population in Los Angeles County remains low.
As of September 5, 2024, the U.S. CDC reported that 53 jurisdictions, led by Florida, New Jersey, New York, and Puerto Rico, have reported 4,369 dengue cases this year. In 2023, 52 U.S. jurisdictions reported 2,343 dengue cases.
The CDC wrote that these local dengue cases reinforce the presence of infected mosquitoes and underscore the importance of preventive measures to control the spread of this virus.
As of September 10, 2024, dengue vaccines are not offered in the United States.
According to a new modeling study published by the Canadian Medical Association Journal, targeting respiratory syncytial virus (RSV) vaccinations to older adults (70+) with underlying health conditions is the most cost-effective way to reduce disease.
Published on September 9, 2024, this study found RSV vaccinations based on age plus risk for RSV-related complications were projected to avert a median of 20% to 31% of outpatient cases, 38% to 42% of hospital cases, and 39% to 42% of related fatalities.
“Strategies focused on adults with underlying medical conditions that place them at increased risk of RSV disease are more likely to be cost-effective than general age-based strategies,” wrote Dr. Ashleigh Tuite, the Centre for Immunization Programs at the Public Health Agency of Canada and the Dalla Lana School of Public Health, University of Toronto, Toronto, Ontario, with coauthors.
“We found that vaccination of older adults may be less costly and more effective than no vaccination and that vaccinating people aged 70 years and older with chronic medical conditions is likely to be cost-effective based on commonly used cost-effectiveness thresholds.”
Three approved RSV vaccines are available in the United States for the 2024-2025 season. These vaccines are generally available at clinics and pharmacies in the United States.
Evaxion Biotech A/S today announced new clinical phase 2 data for its lead compound EVX-01. The data show that 11 out of 16 patients had objective clinical responses, equaling a 69% Overall Response Rate, and 15 out of the 16 patients had reduced tumors.
This topline data is part of a one-year interim analysis of the ongoing phase 2 trial assessing EVX-01 in combination with Merck & Co., Inc. anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) in patients with advanced melanoma.
EVX-01 is a personalized peptide-based neoantigen cancer vaccine/therapy (immunotherapy) for the first-line treatment of multiple advanced solid cancers. This combo therapy is tailored to target each patient's unique tumor profile and immune characteristics. It engages the patient’s immune system to fight off cancer by mounting a targeted response against tumors.
"A huge unmet medical needs remain in the field of melanoma, and we believe that EVX-01 could be an improved treatment option for patients. We look forward to presenting the complete one-year dataset at ESMO, discussing the data with potential partners, and advancing the phase 2 trial towards its completion next year,” says Christian Kanstrup, CEO of Evaxion, in a press release on September 9, 2024.
In the completed Phase 1/2a clinical trial, vaccine-induced T cells were detected in all patients.
OSE Immunotherapeutics SA today announced the launch of its international Phase 3 clinical trial (Artemia) of Tedopi®, the ‘off-the-shelf’ neoepitope-based therapeutic cancer vaccine, in second-line treatment in patients with metastatic non-small cell lung cancer (NSCLC).
Tedopi® (immunotherapy activating tumor-specific T-cells, off-the-shelf, neoepitope-based) is the most advanced therapeutic cancer vaccine in development.
This pivotal study, accepted in 14 countries by international health agencies (Canada, Europe, U.K., U.S.), supports the registration of the product Tedopi® in parallel with the companion diagnostic for HLA-A2 positive patients.
Nicolas Poirier, CEO of OSE Immunotherapeutics, said in a press release on September 10, 2024, “This international registration trial is now on track, and we look forward to confirming the therapeutic benefit of Tedopi® for metastatic cancer patients."
"Tedopi® is the most advanced therapeutic cancer vaccine in clinical development and the first treatment option to address the high unmet medical need and largely untapped market in advanced and metastatic second-line NSCLC. “
NSCLC accounts for 85% of all lung cancers, and the HLA-A2 phenotype represents about 45% of the population.
Each year, more people die of lung cancer in the U.S. than of colon, breast, and prostate cancers combined. Lung cancer accounts for about 20% of all cancer deaths.
The American Cancer Society (ACS) estimates for lung cancer cases for 2024 are:
- About 234,580 new cases of lung cancer (116,310 in men and 118,270 in women),
- About 125,070 deaths from lung cancer (65,790 in men and 59,280 in women).
On a positive note, the ACS says the number of deaths from lung cancer continues to decrease due to fewer people smoking and advances in early detection and treatment.
Since 2023, outbreaks of Oropouche virus disease have been primarily reported in South America but have recently been reported throughout the Region of the Americas.
Published on September 6, 2024, the Pan American Health Organization (PAHO) Epidemiological Update Oropouche in the Americas disclosed that 9,852 confirmed cases, including two deaths, have been reported this year.
Confirmed cases were reported in eight countries: Bolivia (356), Brazil (7,931, including two deaths), Canada (1 imported case), Colombia (74), Cuba (506), the Dominican Republic (33), Peru (930 cases), and the United States (21 imported cases, in 3 states).
The PAHO reiterated its recommendations on diagnosis and clinical management, laboratory diagnosis, prevention, and vector control of Oropouche virus disease. The disease is spread to people by the bites of infected biting midges, and some mosquitoes can also spread the virus.
The likelihood of Oropouche spreading widely in the continental U.S. is low because of differences in climate, types of biting midges, and mosquitoes. However, public health authorities have assessed the risk to human health in the Americas as very high.
The U.S. CDC Level 2 Travel Health Notice says Oropouche cases have been traced to vertical infection causing congenital malformation or fetal death associated with infection. Investigations on vertical transmission and malformation risk remain under assessment in various countries.
Therefore, the CDC recommends that pregnant women avoid non-essential travel to areas with reporting Oropouche cases.
The clinical presentation of Oropouche virus disease is commonly mistaken for other arboviruses, such as dengue and chikungunya.
Diagnosis of Oropouche virus disease can be challenging. It requires a positive RT-PCR result from blood samples collected within six days of symptom onset. After this period, serology could be diagnostic, but commercial kits for the Oropouche virus are currently unavailable.
While preventive vaccines for chikungunya (IXCHIQ®) and dengue available, no Oropouche vaccine is available in 2024.
