CDC Prepares New Vaccine in Response to New Strain of Swine Flu

Posted: September 25th, 2012 | Author: | Filed under: Passport Health Sarasota-Bradenton Announcements | Tags: , , , | Comments Off on CDC Prepares New Vaccine in Response to New Strain of Swine Flu

The U.S.Centers for Disease Control isn’t taking any chances when it comes to swine flu. A new strain of the flu–H3N2–includes an element seen in the H1N1 swine flu pandemic of 2009, so the CDC is preparing a candidate vaccine and clinical trials for later this year.

Doctors have identified 29 human cases of the new strain in the past two years, with all such cases containing the matrix (m) gene found in the H1N1 pandemic virus. “This ‘m’ gene may confer increased transmissibility to and among humans, compared with other variant influenzas viruses,” said Joseph Bresee, from the CDC’s influenza division, as quoted by HealthDay. Part of the concern comes from the rate of infection; of the 29 cases reported, 16 occurred in the past three weeks, Bresee said.

Person-to-person transmission of the disease has yet to take place, which should ease some concerns at this time. In the reported cases, the individuals had close contact with animals carrying the virus, including time spent at a fair. But the CDC takes comfort in preparation.

“Because influenza viruses are always evolving, we will watch closely for signs that the virus has gained capacity for efficient and sustained human-to-human transmission,” Bresee said. “Thus far, we have not seen this type of transmission and therefore are not seeing features consistent with an influenza pandemic.”


Breakthrough in the Search for a Malaria Vaccine

Studies show people immune to the disease develop antibodies that home in on a protein known as PfEMP1, produced by Plasmodium falciparum, the organism behind most cases of malaria, according to Medical Xpress. The findings prove valuable in determining for which malaria proteins–known as variant surface antigens–a vaccine should aim. The study also showed that when the immune system takes action against other proteins produced by malaria, it does not effectively protect the body, further underscoring the need for a vaccine to seek out the appropriate target.

“The new findings support the idea that a vaccine could be developed that stimulates the immune system so that it specifically mounts a strong response (or attack) against the PfEMP1 protein that malaria produces,” James Beeson, senior author of the study, tells Medical Xpress.

More than 40% of the world’s population live in areas where there is a risk of contracting the mosquito-borne illness, which will make developing a vaccine both profitable to the manufacturer and beneficial to world health. Nearly 1 million individuals die of malaria each year, according to the NIH.

Finally! A Vaccine for Allergy Relief

Posted: September 18th, 2012 | Author: | Filed under: Passport Health Sarasota-Bradenton Announcements | Tags: , , , , | Comments Off on Finally! A Vaccine for Allergy Relief

Allergy Therapeutics will court a partner to market its Pollinex Quattro Grass vaccine now that the FDA lifted a clinical hold on the grass pollen allergy shot.

The company can move forward with a Phase III efficacy study, which will take place in an environmental exposure chamber, according to a release. The vaccine–commercialized in some European countries–comes as a four-shot series, requiring the injections over the course of a year.

The FDA froze the vaccine in 2007, after a volunteer experienced numbness and weakness during a trial. Allergy Therapeutics’ stock tumbled 22% at the time, according to FierceBiotech. But the U.K.-based company’s shares jumped almost 30% after the FDA lifted the hold.

“This product has the potential to greatly benefit allergy sufferers in the U.S.in the absence of registered products by being the first subcutaneous immunotherapy vaccine to reach the U.S.market,” said CEO Manuel Llobet. “Additionally, lifting the hold will allow for discussions with potential partners with whom we will finalize the clinical development and start the commercialization of Pollinex Quattro in a market estimated to be around $2 billion.”


Client Story: Healthy Travels in Chennai

Posted: September 17th, 2012 | Author: | Filed under: Passport Health Sarasota-Bradenton Announcements | Tags: , , , , | Comments Off on Client Story: Healthy Travels in Chennai

I recently visited Passport Health in anticipation of a two-week trip to India.  The purpose of my trip was to improve upon the meditation that I practice here at home.  My main destination of interest was a large celebration at an ashram in Chennai.  A couple of weeks before leaving, the location of the celebration was changed.  At first I was worried about the sudden change of plans, but it ended up allowing me the opportunity to visit three different locations and have a very interesting and wonderful time.

My travels started with a series of flights stopping in New York, Brussels, and then finally in Chennai, India.  I then caught a domestic flight to Coimbatore, and a taxi ride from Coimbatoreto Tiruppur.  I was fairly tired after almost 35 hours of traveling, but I was immediately welcomed with a delicious lunch and a cup of chai tea as I arrived in Tiruppur.  There was already a large gathering of nearly 60,000 people from around India and the rest of the world.

Meditating at an Ashram

This is the interior of the main meditation tent.

The accommodations were just large tents shared with fellow travelers, but were completely comfortable and even cozy.  I also really looked forward to the three healthy, freshly cooked meals served each day.

This is a photo of my accommodations

My accommodations were nice, even cozy.

After three days of relaxing meditations and inspiring lectures, I had the fortunate opportunity to spend some time at a mountain retreat center located in the jungles of Kerala.  It is one of the most beautiful places I have ever seen.  It was also a perfectly tranquil atmosphere that allowed for plenty of introspecting, relaxing, and recharging.

The Mountain Retreat was the perfect place to relax and recharge

It was easy to make new friends at the retreat center, and we traveled together to the ashram in Chennai, where I spent my last two days in India.  I didn’t do very much traditional tourism while in India, but I did get to spend a few hours traveling to markets in the city center.  We traveled via an open, motorized rickshaw in heavy traffic, which was a bit of an adventure.  After returning to the ashram, I enjoyed some great conversations with people from around the world.  While everyone had different experiences and perspectives in their lives, there is a definite bond and camaraderie in a place like the ashram.  Overall it was a pretty amazing journey, and I would encourage anyone who is at all interested to pursue a similar experience for themselves.

Vaccine Company Fights Antitrust Allegations

Posted: September 13th, 2012 | Author: | Filed under: Passport Health Sarasota-Bradenton Announcements | Tags: , , , , , | Comments Off on Vaccine Company Fights Antitrust Allegations

Sanofi Pasteur may find itself in the thick of an antitrust case after a judge ruled that a lawsuit alleging that the company illegally monopolized the market for meningococcal vaccines in theU.S. can move forward.

In December, several doctors said the company created a “web of noncompetitive contracts” with physician buying groups that blocked competition in an effort to sell its vaccine MenactraPharmalot reports. Using its market authority, Sanofi grouped price contracts, forcing purchasers to buy 90% or more of childhood vaccines to avoid potential cost penalties on Menactra, according to the news service. So, in theory, a buyer could end up paying 15% to 35% more for all Sanofi vaccines if they elect not to buy Menactra. The doctors surmise Sanofi’s idea here was to promote its Menactra vaccine after Novartis ($NVS) joined the game with rival Menveo.

Furthermore, the lawsuit says the doctors were told, under contract, not to purchase vaccines from other makers–such as GlaxoSmithKline ($GSK) and Novartis–or they would face penalties.

A Sanofi Pasteur spokesman wrote to Pharmalot, “naturally we are disappointed in the judge’s ruling, but we are confident that once the court sees the evidence of competition in the marketplace, it will rule against the plaintiffs. We continue to defend our company and our product, and we maintain that allegations in the class action complaint are without merit.”


Tuberculosis Vaccine May be Used to Cure Diabetes

Posted: September 11th, 2012 | Author: | Filed under: Passport Health Sarasota-Bradenton Announcements | Tags: , , , , , , | Comments Off on Tuberculosis Vaccine May be Used to Cure Diabetes

A tuberculosis vaccine may help reverse Type 1 diabetes, a disease for which there is no cure. Harvard University researchers are raising money to conduct human studies using the 90-year-old vaccine bacillus Calmette-Guérin, also known as BCG, to help produce a protein that kills insulin-attacking cells, Bloomberg reports.

Three million Americans suffering from Type 1 diabetes use insulin injections to control the illness. In the study with the BCG vaccine, researchers administered two doses to three patients with Type 1 diabetes and found signs of increased insulin production after 20 weeks in two of the patients. A rise in C-peptide levels suggested the production of insulin, Bloomberg reported.

“These patients have been told their pancreases were dead,” Denise Faustman, director of Harvard-affiliatedMassachusetts GeneralHospital’s immunobiology laboratory, told Bloomberg. “We can take those people, give them a very low dose twice and see their pancreases kick in and start to make small amounts of insulin.”

Faustman and her colleagues are now trying to raise the $25 million necessary to conduct larger human trials. In an effort to bring the vaccine to market, she found every major drugmaker expressed no interest in using an inexpensive, generic drug as a cure for diabetes because there was not enough money to be made, according to Bloomberg. All money for the study is coming from private donors.

Hospital patients, particularly those on respirators, can contract infections from bacteria known as Pseudomonas aeruginosa. However, researchers at Brigham and Women’s Hospital in Boston say they discovered a new vaccine candidate that aims to fight such infections.

Researchers observed protection from lethal pneumonia in mice after either active or passive immunization, according to a study published in the American Journal of Respiratory and Critical Care Medicine.

No known vaccine exists to stomp out the bacteria, which is also responsible for some lung infections in people with cystic fibrosis.

The vaccine is based on a new system of immunity to Pseudomonas assisted by T helper 17 (Th17) cells, according to a release. The Th17 cells secrete the cytokine IL-17 and boost antibacterial mucosal defenses.

“People have been trying to make vaccines for Pseudomonas for more than 40 years,” Dr. Gregory Priebe, assistant professor of anesthesia in the Division of Infectious Disease at Brigham and Women’s, told FierceVaccines. “Most bacterial vaccines use kind of the other armor of the immune system, meaning antibodies. You really need both; you need antibody and these T helper 17 cells.”

Researchers have been working on vaccines for both the acute infections and for Pseudomonas and cystic fibrosis, Priebe said.

PsiOxus Therapeutics amassed $34 million for its Series B. The round will allow the London-based company to move forward with clinical development of a systemically available oncolytic vaccine for the treatment of colorectal and other forms of cancer, ColoAd1, through a series of Phase I and Phase II clinical trials, according to a release.

The lead vax is designed to replicate in and kill only cancer cells. The infected cells then reproduce, fanning out as cancer-fighting agents. The so-called “self-amplifying” cancer therapy both kills tumors and acts as a cancer vaccine.

Money for the trials comes from existing investors, Imperial Innovations Group and Invesco Perpetual. And PsiOxus has brought on new investments from GlaxoSmithKline’s venture unit SR One and Lundbeckfond Ventures.

“This financing comes at a pivotal time for our company as we move our cancer portfolio from early- to mid-stage clinical development,” said Dr. John Beadle, CEO of PsiOxus, as quoted in a release. “The new funding will enable key clinical trials to demonstrate the safety and proof of efficacy of these products in the clinic and to highlight the effectiveness of our research and development program.”

The first clinical trial of ColoAd1 will take place later this year in patients with metastatic solid tumors.


New Obesity Vaccine? Possible

Researchers at Braasch Biotech seeking an obesity vaccine for humans achieved promising results in a study using mice. They found that chubby mice quickly shed 10% of their body weight when injected with modified somatostatin, a peptide hormone.

The scientists fattened up the mice over the course of 8 weeks and right through the 6-week study. The mice received a dose of the vaccines–two somatostatin vaccinations, JH17 and JH18–at the beginning of the study and on day 22. The vaccines lead to production of antibodies to somatostatin–a hormone peptide that blocks activity of growth hormone and insulin-like growth factor (IGF-1)–in order to boost energy use and burn fat. Four days after the first vaccine injections, the overweight mice dropped 10% of their body weight without negative effects on growth hormone, IGF-1 or insulin levels, according to a release.

“This study demonstrates the possibility of treating obesity with vaccination,” said Keith Haffer, a scientist at Braasch Biotech, in a statement. “Although further studies are necessary to discover the long-term implications of these vaccines, treatment of human obesity with vaccination would provide physicians with a drug- and surgical-free option against the weight epidemic.”

A juggernaut of hype will surely follow the release of a vaccine to combat obesity, a common cause for heart disease and Type 2 diabetes, but animal testing only preludes the years of human clinical trials ahead.
