Start of phase 2 trial in newborn infants in South Africa with VPM1002, a new vaccine developed by an Indo-German co-operation for prevention of tuberculosis
08.07.2015 -- Enrollment of the first infant in a phase 2 clinical trial of a new vaccine to prevent tuberculosis (TB) has successfully started. VPM1002, the most advanced new TB vaccine in clinical development, will help curtail spread of life-threatening TB disease not only in endemic countries, but also in Europe. The vaccine candidate VPM1002 was recently out-licensed to Serum Institute of India Ltd. (SIIL), the world’s largest vaccine manufacturer according to number of doses sold. VPM1002 is developed by SIIL in collaboration with Vakzine Projekt Management GmbH (VPM). Mr. Adar C. Poonawalla, CEO and Executive Director of SIIL emphasizes that “TB still remains a major public health problem and only a new and more effective vaccine can help to restrict the expansion of multidrug-resistant and extremely drug-resistant TB and thus save the lives of millions of people each year. We are pleased with the start of this trial as it represents one more step in our efforts to continuously improve existing vaccines, and to make new, safe, efficacious and cost effective vaccines available to the world, especially for TB. This is also shown in our plans to start large trials with VPM1002 to address the challenges of relapsing TB in adults.”
Professor Stefan H. E. Kaufmann, the Founding Director of the
Max Planck Institute for Infection Biology, who was largely
responsible for the scientific concept of VPM1002, adds:
“The former BCG vaccine continues to be the most commonly
administered vaccine. Although it can protect against certain
forms of tuberculosis, its protective efficacy is insufficient
and alarmingly, BCG-related adverse events in HIV positive
newborns frequently occur. BCG also poses a high risk for any
infant born with congenital genetic immunodeficiency.” And
he continues saying that the goal with VPM1002 is “to
sharpen BCG’s blade, and make it safer and more
efficacious for successful combat of tuberculosis.”
The
new vaccine VPM1002 was co-developed by scientists from the Max
Planck Society (MPG) and Hannover-based VPM, a spin-off company
from the Helmholtz Centre for Infection Research (HZI). VPM1002
was modeled on an earlier TB vaccine called BCG – short
for Bacillus Calmette–Guérin – that was first
introduced in 1921, and since then has been given to millions of
infants each year where TB is prevalent. What makes VPM1002
unique when compared with BCG is the fact that targeted genetic
modifications make the vaccine much safer and more effective in
preventing TB. A series of studies in animal models, and two
separate phase I clinical trials in adults and one phase 2a
clinical trial in newborn infants, have already confirmed safety
and have shown sufficient strengthening of the immune system
against TB, thus raising hope for higher efficacy.
“Already during the phase I clinical trials in Europe and
Africa, the new vaccine showed better tolerance and triggered a
more targeted immune response than classical BCG. These
promising findings were confirmed in a subsequent phase 2a trial
in newborns, our ultimate target group,” confirms Dr.
Bernd Eisele, VPM’s CEO. “And now, enrolling the
first infant in the current phase 2 clinical trial in
HIV-exposed infants, that is, infants who need a safer and
better vaccine the most, is a huge success. It brings us one
important step closer to including the new vaccine in a global
plan of action against TB by the end of this decade.”
The
phase 2 clinical trial currently taking place in South Africa, a
TB hotbed, commenced this June and is the first investigation of
the vaccine in HIV-exposed infants. Especially HIV-exposed
infants may suffer from severe adverse events after vaccination
with the common BCG and therefore are in urgent need of a safer
and more effective vaccine. According to the clinical
trial’s principal investigators, Professor Mark Cotton and
Professor Anneke Hesseling of Stellenbosch University and
Desmond Tutu TB Center, Dr Angelique Luabeya from the South
African Tuberculosis Vaccine Initiative (SATVI) and Professor
Shabir Madhi of the Respiratory and Meningeal Pathogens Research
Unit (RMPRU), “this trial with VPM1002 is an important
milestone in our global fight against TB’s deadly threat
– the disease currently afflicts about two billion
people.”
Dr. Leander Grode, Kaufmann’s
former research fellow and co-inventor, who has since become
Chief Scientific Officer at VPM, contributed substantially to
VPM1002’s development. “We have successfully
modified the original vaccine in such a way that it is now
better at activating the human immune system, thereby affording
more protection and safeguarding against the TB pathogen,”
Grode explains.

VPM is a public–private partnership venture based in
Hannover, Germany, and was founded in 2002 jointly by the
German Federal Ministry for Education and Research and the
Braunschweig based Helmholtz Centre for Infection Research.
Drawing on its professional project management expertise and
long-standing drug design experience, VPM is able to support
researchers and show that their innovations have the potential
to move out of the research labs and into clinical
application, to ultimately benefit humankind.
About
Serum Institute of India Ltd. (SIIL)
SIIL was founded in 1966 with the goal of creating
life-saving drugs for people from all walks of life. The
Institute’s special focus has traditionally been on
those countries where drugs were either altogether unavailable
or unaffordable for most people. At this point, the SIIL has
become the world’s largest manufacturer of vaccines
against measles and against diphtheria, pertussis/whooping
cough and tetanus (DPT). The company has continued to increase
its philanthropic focus and now also manufactures vaccines
against hepatitis B, rabies, and meningitis. These efforts
ensure that from the day they are born, all children –
not only in India, but in more than 140 different countries
all over the world – have access to life-saving
medicines.
About
Max Planck Institute for Infection Biology (MPIIB)
Scientists at the MPIIB in Berlin, Germany, are concerned
with the study of different kinds of pathogens and their
effect on the host organism. A central focus of MPIIB’s
research includes pathogens that cause tuberculosis, malaria,
serious gastrointestinal diseases and influenza. In addition
to the acquisition of knowledge, a second focus is on the
development of new vaccines, new drugs and diagnostic
biomarkers.
About
Helmholtz Centre for Infection Research (HZI)
Scientists at the HZI in Braunschweig, Germany, are engaged in the study of different mechanisms of infection and of the body’s response to infection. Improving our understanding of a given bacterium’s or virus’ pathogenicity is key to developing effective new treatments and vaccines.
