Medicago reports positive Phase II final results for its avian flu pandemic vaccine

QUEBEC CITY, Jun 30, 2011, 2011

- Phase II part B confirms results obtained in Phase II part A -

- Company's results continue to be amongst the best for influenza vaccine manufacturing technologies -

Medicago Inc. (TSX: MDG) a biotechnology company focused on developing highly effective and competitive vaccines based on proprietary manufacturing technologies and Virus-Like Particles (VLPs), today reported positive final results from a Phase II human clinical trial with its H5N1 Avian Influenza VLP vaccine candidate ("H5N1 vaccine"). The vaccine induced a solid immune response and was found to be safe and well tolerated.

"These positive Phase II clinical trial results continue to demonstrate that our rapid plant-based vaccine technology produces VLP vaccines that are safe and among the most effective of the industry," said Andy Sheldon, President and CEO of Medicago. "Our Phase II part B data confirms the solid results obtained in Phase II part A for optimal dosing. In addition, our results demonstrated similar efficacy in the older and younger volunteer age groups which is a potential differential advantage over other technologies."

"We soon expect to have the capacity to commercially produce these vaccines as our U.S. vaccine facility in North Carolina will be operational this fall. In addition, we believe these results further support the effectiveness of our rapid plant-based vaccine platform and the development of our seasonal flu vaccine candidate which we intend to proceed with a U.S. clinical trial in the second half of the year," continued Mr. Sheldon.

FDA Authorizes New Hemispherx Biopharma Clinical Trial of Intranasal Ampligen(R) With Seasonal Influenza Vaccine

Press Release Source: Hemispherx Biopharma, Inc. On Wednesday July 20, 2011, 8:00 am EDT

First Clinical Application of Ampligen(R) Intranasally

Excerpt:

PHILADELPHIA, July 20, 2011 (GLOBE NEWSWIRE) -- Hemispherx Biopharma, Inc. (NYSE Amex:HEB) (the "Company" or "Hemispherx") today announced it has received U.S. Food Drug Administration (FDA) authorization to proceed with the initiation of a new clinical trial of intranasal Ampligen(R) [rintatolimod; poly(I).poly(C12,U)] used in conjunction with commercially approved seasonal influenza vaccine. The FDA authorization also requests that certain protocol amendments and pre-clinical items be filed to the Investigational New Drug (IND) Application; these requests are not expected to affect the implementation or timing of the clinical study which will involve healthy volunteers. The primary objective of this study is to evaluate the safety of three cycles of intranasal Ampligen(R) administered three days following each intranasal dose of seasonal influenza vaccine. Other objectives include evaluation of various immune responses to the trivalent seasonal influenza vaccine administered intranasally with and without Ampligen(R). Ampligen(R), a toll-like receptor 3 (TLR3) agonist, is an experimental therapeutic in advanced clinical development for the potential treatment of Chronic Fatigue Syndrome (CFS), an enigmatic disorder which may have certain viral "footprints".
-snip-

A similar study of Ampligen(R) and a seasonal influenza vaccine in mice resulted in cross-protection of the mice against a pandemic form of avian influenza (H5N1). Evidence for cross-reactivity against pandemic forms of avian H5N1 influenza virus will be investigated as one of the objectives of this study. One goal of this approach is to generate protective mucosal immunity against newly emerging strains of H5N1 with pandemic potential using Ampligen(R) as a mucosal adjuvant with trivalent seasonal influenza vaccine.

Harnessing the immune system's arsenal: producing human monoclonal antibodies for therapeutics and investigating immune responses

Abstract

Monoclonal antibody technology has undergone rapid and innovative reinvention over the last 30 years. Application of these technologies to human samples revealed valuable therapeutic and experimental insights. These technologies, each with their own benefits and flaws, have proven indispensable for immunological research and in our fight to provide new treatments and improved vaccines for infectious disease.

Introduction
Excerpt:
This article will explore the history and current state of monoclonal antibody technology and how it has contributed to therapeutics, both through direct clinical treatments and by providing valuable insights into host–pathogen interactions. Importantly, we will highlight how these technologies help identify factors that produce broadly neutralizing antibodies—antibodies that by virtue of binding to certain epitopes important in the viral life cycle, are able to bind many disparate viral strains and prevent them from infecting their target cells. These antibodies are vital in effective therapeutics and, ultimately, successful vaccine design.

In conclusion
Excerpt:
The current state of monoclonal antibody technology is enabling exciting advancements in immunotherapies and understanding of host–pathogen interactions. Maybe more importantly, it is now evident that insight into our natural immune responses can facilitate rational vaccine development. Thus, the most important lessons may be those we’ve garnered from our bodies’ natural responses; not only can we can capitalize on our strengths, such as targeting of specific pathogenic epitopes, but we can also compensate for our inherent weaknesses, such as the rarity of our most powerful antibodies. In the end, the information we gather from monoclonal antibody technology may be more important than the direct attainment of therapeutics (borrowing from an old adage, catch a man a fish and he’ll eat for a day, but teach a man to fish and he’ll eat for a lifetime). Similarly, by studying what antibodies can teach us, we may someday produce vaccines that eradicate many infectious diseases that have a profound impact on human health such as influenza, hepatitis, or HIV.

Ottawa prepares for annual wild bird survey to detect bird-flu levels

August 5, 2011

OTTAWA — Food inspection agents are gearing up to conduct their annual survey of wild birds to check current levels of avian influenza.

The Canadian Food Inspection Agency issued an advance contract notice, which closes next week, for companies interested in overseeing the survey, which examines both dead and live birds all over the country and detects levels and patterns of bird flu.

The study, first launched in 2005, identifies disease-causing strains, such as the deadly H5N1, in wild geese, ducks, swans and other fowl so government officials can better determine how to stop their spread should there be an outbreak.

Thousands of deadly bird flu virus in chickens Polewali Mandar. 1
Sidrap, KOMPAS.com - Attack avian influenza (AI) or bird flu is still haunting farms in 11 districts in Sidrap, South Sulawesi.

Although relatively little appeal in the peak of bird flu in July 2001, but the attack was a chicken farmer concerns at the center of the largest chicken farms in the South Sulawesi.

Until this afternoon, Wednesday (08/03/2011), there were already 215,938 chickens that died suddenly due to bird flu. This type of laying chicken is a type of chicken the most attacked that amounted to 161,584 head, followed by type of broiler chicken and chicken instead of the tail 40 005 22 593 race tail.

"So far bird flu is under control in the District Sidrap. Even if there are chickens and other fowl that died suddenly due to bird flu, is relatively much smaller scale," Chief District Veterinary Sidrap Sadelih.

Separately, Syamsiah, Bird Flu Response Officer (PSDR) said this year is the third year, the District Sidrap zoned for bird flu outbreak, which originated from the village Wanio, District Panca Lotang, who attacked the farm owned by H Jafar laying hens.

"Beginning with the death of 300 chickens owned by Jafar, ranchers Wanio. Testing with rapid tests indicate that if the chickens owned by residents is positive of bird flu. From there, the virus quickly spread to 11 other districts," he explained.

In addition to spraying, to save the other birds that have not been exposed to the virus, given turmeric and brown sugar in a way in Drinks. It is fairly powerful, in addition to minimizing the use disinvektan whose numbers dwindling.

"Turmeric contains anti-oxidants that serve to minimize the virus and anti-biotic substances to poultry and red sugar serves to maintain stamina chicken," he explained.

Chicken in Makassar Safe for Consumption...says Indonesia..

Eastern Tribune - Tuesday, August 2, 2011 22:34

Makassar, Tribun-TIMUR.COM - Marine Service, Fisheries, Livestock and Horticulture Makassar City asserts that the meat on the market during Ramadan is safe for residents although few weeks before entering the Ramadan found positive bird flu virus in several regencies in South Sulawesi.

"We conduct regular monitoring and all meats are traded on the market Makassar safe for consumption, either chicken, beef, goat and others," said Head of the Department of Marine, Fisheries, Livestock and Horticulture Syaiful Saleh Makassar in Makassar, on Tuesday (2 / 8 / 2011).

He said the consumption of meat during Ramadan is high enough and to ensure the meat consumed by the residents safe, the institute routine monitoring on the traditional market and modern market.

Tightened oversight of meat imports into the city of Makassar, following the discovery that the import of meat outdated and not worth the consumption of a few weeks ago.

"The tightening oversight of meat imports, to anticipate the presence of inappropriate consumption of meat and can endanger health, especially at the present time we want to provide reassurance to residents who are running fast," he said.

The spread of Bird Flu Spreads Kian

Reny Sri Ayu Taslim Agus Mulyadi Tuesday, August 2, 2011 22:30 pm

HAMMER, KOMPAS.com - Since the outbreak early July, the spread of bird flu virus in Palu, Central Sulawesi, and the surrounding areas are increasingly widespread.

Until Tuesday (08/02/2011) was reported, had hundreds of chickens or birds that died suddenly. Even on a Tuesday afternoon, still happen livestock cases of sudden death. Efforts have been done spraying the Department of Agriculture, Forestry, and marine Palu but the results have not been up.

"Spraying is not maximized because of the new enclosure's farmer sprayed the report. There was the case but the owner did not report, still not dis emprot. We also constrained the lack of disinfectants," said Hasniwaty, Head of Livestock, Agriculture, Forestry, and Marine City Palu, on Tuesday.

According Hidnawaty, efforts to suppress the spread of bird flu virus that made the Department of Agriculture, Forestry, and Marine Palu hampered lack of disinfectant. For spraying purposes, by far the disinfectant used is a residual stock of last year. This year, there has been no provision for the disinfectant.

"We've asked the city government to hold a disinfectant. This year there is no provision, because last year free of bird flu Palu. So for the only remaining stock that we use. We do not yet know how many are needed, but for a while based on the number of cases We need at least 10 dos disinfectant. One dos typically contains 12 doses, "said Hasniwaty.

Based on field data on the Agriculture Department of Animal Husbandry, Forestry, and Marine Palu, of which there are 43 urban villages, as many as eight of whom are stricken with bird flu. Urban Village, among others Donggala Kodi, South Lolu, Tana Modindi, Duyu, Kamonji, North Tatura, Talise, as well as the Middle Besusu.

Initially pigeon bird flu attacking livestock in the village of Donggala Kodi. Furthermore, the attacks spread to poultry and neighboring districts, up to now total there are eight districts affected by the number of livestock that died more than 300's tail.

Related to this, the mayor of Palu, Rusdi Mastura, issued a circular letter 443.1/270/Disperhutla numbers, to all district head to anticipate the growing spread of bird flu. The district head of whom was asked to do spraying disinfectant into the cages of livestock owned by residents.

In addition, agencies and the subdistrict was also ordered to monitor incoming traffic kaluar chicken and from Palu. It is suspected bird flu through poultry originating from outside the city of Palu, but no one has known from the area where it came from. In addition, the bird flu virus is also thought to spread due to weather changes from rain to heat.

WHO Update: Avian influenza – situation in Cambodia - update 5

2 August 2011 - The Ministry of Health (MoH) of the Kingdom of Cambodia has announced a confirmed case of human infection with avian influenza A (H5N1) virus.

The case was a 4 year old female from Chork Reaksmey Village, Rohath Teuk Comune, Mongkul Borei District, Banteay Meanchey Province. She developed symptoms on 11 July, was initially treated by local private practitioners with no effect and was later admitted to Jayavarma VII Hospital on 18 July. She died on 20 July, two days after admission.

There have been reports of poultry die off in her village and the case is reported to have had exposure to dead poultry. The female is the seventeenth person in Cambodia to become infected with the H5N1 virus and the fifteenth to die from complications of the disease. All seven cases of H5N1 infections in humans in Cambodia this year have been fatal.

The National and local Rapid Response Team (RRT) is conducting outbreak investigation and response following the national protocol.

There is no evidence of increased ILI activity in the local health centre or any increase in number of SARI cases from the affected village. Thirteen contacts were tested for A/H5N1 influenza, all of whom were negative. There is enhanced surveillance for ILI and SARI in the local health centre and hospital for a further two weeks. Health education messages are ongoing in the community.
