CDC Publishes COVID-19 Vaccination 'Playbook'

The U.S. CDC published a 'playbook' on September 16, 2020, which says 'immunization with a safe and effective COVID-19 vaccine is a critical component of the United States strategy to reduce COVID-19-related illnesses, hospitalizations, and deaths and to help restore societal functioning. The goal of the U.S. government is to have enough COVID-19 vaccine for all people in the United States who wish to be vaccinated.'

'Early in the COVID-19 Vaccination Program, there may be a limited supply of vaccines, and vaccination efforts may focus on those critical to the response, providing direct care, and maintaining societal function, as well as those at highest risk for developing severe illness from COVID-19.'

Information in this interim playbook will be updated as new information (e.g., recommendations for pregnant women or pediatric populations) becomes available, said the CDC.

Combination Treatment Reduces Coronavirus Viral Load by Nearly 100%

Innovation Pharmaceuticals reported on September 15, 2020, receiving additional data from a U.S. Regional Biocontainment Laboratory (RBL) collected during ongoing in vitro testing supporting Brilacidin as a potential treatment for SARS-CoV-2, the novel coronavirus responsible for COVID-19. 

In human lung epithelial cell line experiments performed at the RBL, Brilacidin in combination with Remdesivir, compared to Remdesivir-only treated conditions, showed statistically significant and synergistic inhibition of SARS-CoV-2.

Of particular note, overall viral load was reduced by 99.85 percent in one combination experiment, with the remaining coronavirus dropping to nearly undetectable levels.

Brilacidin is one of the few drugs targeting COVID-19 that has been tested in human trials (a total of 8) for other clinical indications, providing an established safety and efficacy database on over 460 subjects, thereby potentially enabling it to rapidly help address the SARS-CoV-2 coronavirus pandemic.

Scientists Debate Russia's Coronavirus Vaccine's Fast-Track Process

An open letter to the study authors who recently published clinical trial results in The Lancet on September 4, 2020, says that 'the paper presents its results only as box plots without providing a detailed breakdown of the data on which they are based.'

“While the research described in this study is potentially significant, the presentation of the data raises several concerns which require access to the original data to fully investigate”, the letter in Nature says. This letter has been signed by 38 scientists, as of September 15, 2020.

In August 2020, Russian authorities approved the Sputnik V vaccine for widespread use, and have said that it could be available to the general public in November 2020. This fast-track approval caused consternation among researchers, who argued that the decision to roll out the vaccine before larger safety and efficacy trials had been completed was rushed.

Shingles Vaccine Candidate Produced 'Robust Antibody Responses'

Curevo Vaccine, a Washington-based biopharmaceutical company announced on September 15, 2020, antibody response data from its completed Phase 1 study investigating the safety, tolerability, and immune system response of the CRV-101 vaccine candidate targeted against the Shingles virus in several formulations.

The administration of Curevo’s adjuvanted sub-unit Shingles investigational vaccine resulted in a robust antibody response against a key component of the shingles virus at 1 month after 2nd vaccination, and at 1-year. The Phase 1 study included 89 subjects, with solicited reactogenicity adverse events consisting of no grade 3 local injection site events and only one grade 3 systemic event (fever) in the highest dose group.

“The frequency of grade 2 individual solicited reactogenicity events, including pain at the injection site, were less than 6.5% overall CRV-101 doses. Currently licensed adjuvanted gE subunit vaccine studies have shown higher reactogenicity in younger populations, so we do not expect to see increased reactogenicity in the target age group of 50 years or older,” said Lisa Shelton, ARNP, Associate Director of Clinical Operations.

Curevo's press release stated it will present results from their Phase I trial at the virtual World Vaccine Congress Washington conference.

Pittsburgh Takes the Lead of the NIH's Blood Thinner Studies

The US National Institutes of Health announced on September 10, 2020, it has selected the University of Pittsburgh to lead a trio of Phase 3 clinical trials involving COVID-19 patients. Collectively known as ACTIV-4 Antithrombotics, these late-stage trials will explore the use of blood thinners in saving lives and improving care, particularly among adult COVID-19 patients who are at risk of developing life-threatening blood clots.

Researchers and clinicians have noted that many patients who have died from COVID-19 formed blood clots throughout their bodies, including in their smallest blood vessels. This unusual clotting causes multiple health complications, from lung and other organ damage to heart attacks, pulmonary embolism, and strokes.

Antithrombotics, also known as blood thinners or anticoagulants, keep blood protein and platelets from turning into clumps or sticking to each other. However, doctors have not yet figured out if, and at what point in the course of COVID-19 disease, blood thinners might be effective at treating patients with this new condition.

The Lancet published a new study on September 3, 2020, reporting on a phase 1/2 clinical trial evaluating a vaccine composed of capsular polysaccharide conjugated to cross-reactive material 197 (CRM197) and directed against 6 capsular polysaccharide serotypes of group B streptococcus (GBS). These serotypes (Ia, Ib, II, III, IV, and V) account for the vast majority of isolates causing invasive GBS disease worldwide.... in neonates, as well as in adults.

These authors report that 3 different doses of this Pfizer hexavalent vaccine candidate formulated with or without aluminum phosphate as its adjuvant were safe and well-tolerated in healthy, non-pregnant, adult volunteers. And, the vaccine elicited a robust immune response for at least 6-months.

Chikungunya Vaccine Candidate Launches Phase 3 Clinical Study

France based Valneva SE announced on September 8, 2020, the initiation of a pivotal Phase 3 clinical trial for its differentiated, single-shot chikungunya vaccine candidate VLA1553, the first chikungunya vaccine to be eligible to receive an FDA Priority Review Voucher. This vaccine candidate is designed for prophylactic, active, single-dose immunization against chikungunya. As a live-attenuated vaccine, VLA1553 is particularly well suited to target long-lasting protection. 

The safety profile is anticipated to be similar to licensed vaccines for active immunization in adults and children.

Wolfgang Bender, M.D., Ph.D., Chief Medical Officer of Valneva, commented in a press statement, “Developing a vaccine against chikungunya is critical as the virus represents a major public health threat and there are currently no preventive vaccines or effective treatments available."

Intranasal Pertussis Vaccine Candidate Found Safe and Immunogenic

The Lancet reported the early-stage vaccine candidate BPZE1 was found safe, induced a high colonization rate in an adult population, and was immunogenic at all doses. 'These findings justify further clinical development of the live attenuated, intranasal pertussis vaccine BPZE1, to ultimately be used as a priming vaccine for newborn children, or a booster vaccine for adolescents and adults, or both,' concluded this study.

The BPZE1 strain was developed at the Institute Pasteur de Lille and Inserm by a team of scientists led by Dr. Camille Locht. BPZE1 contains genetic modifications to eliminate, attenuate, or inactivate (3) different B. pertussis toxins. BPZE1 is an investigational vaccine that has not been approved by the U.S. FDA.

Mexico Launches Coronavirus Vaccine Development Effort

Esther Orozco, the coordinator of the scientific group that represents Mexico at the Coalition for Epidemic Preparedness Innovations, told Reuters on September 6, 2020, 'research based on a virus that transmits the avian Newcastle Disease is the most viable candidate to produce the first vaccine in Mexico. ND is caused by infections with one of the different strains of virulent avian Newcastle disease virus, recently renamed Avian avulavirus.

And, the vaccine is being developed by Laboratorio Avimex with researchers from Mexico’s UNAM, and the Mexican Social Security Institute. Orozco said it is 'ready to start the first phase of testing with humans.'

SARS-CoV-2 Pandemic Significantly Decreased Shingles Vaccinations

Since the declaration of the COVID-19 pandemic in January 2020, ordering rates across adult vaccines decreased an average of 62%, reported IQVIA. This data is most concerning for seniors who incur the most illnesses, hospitalizations, and deaths from vaccine-preventable illnesses that occur among adults.

To counter this trend, GSK launched a media campaign on August 5, 2020, to help increase vaccination among older adults. GSK has launched a website where adults ages 50 and older can learn about the value and importance of vaccines and see a list of vaccines routinely recommended for their age group. The vaccine awareness campaign will run through 2021.

A highlighted shingles vaccine for seniors is Shingrix, since nearly most adults 50+ years of age carry the inactive chickenpox virus that can cause shingles. Through March 2020, about 17 million people had received the Shingrix vaccine, with about 80% of them completing their 2-dose series, reported GSK.

Hydroxychloroquine Found Not Associated with Lupus Patient's Hospitalized Infections

A study published on August 24, 2020, compared the risk of hospitalized infection (HI) between users and non-users of the antimalarial drug hydroxychloroquine (HCQ) in systemic lupus erythematosus (SLE).

These researchers from Japan found that the use of HCQ, also known by the brand name Plaquenil, is not associated with short-term risk of HI, which refers to both hospitalizations that occur due to infections, as well as infections that occur during hospitalization. The use of HCQ was not approved for lupus treatment in Japan until 2015.

This study has heightened relevance regarding the ongoing debate of treatment options for non-severe COVID-19 disease patients.
