Pharmaceutical companies have managed their business in much the same way for decades. But significant changes in government regulations, market conditions, and technology will force the industry to look for new business models and practices. Companies that don't adapt face an uncertain and unsettling future.

DEERFIELD, Ill.--(BUSINESS WIRE)--Baxalta Incorporated (NYSE:BXLT), a global biopharmaceutical leader
dedicated to delivering transformative therapies to patients with orphan
diseases and underserved conditions, today announced that the Committee
for Medicinal Products for Human Use (CHMP) of the European Medicines
Agency (EMA) has adopted a positive opinion for the marketing
authorization of OBIZUR [Antihemophilic Factor (Recombinant), Porcine
Sequence].
Baxalta is seeking market authorization in Europe of OBIZUR for the
treatment of bleeding episodes in adult patients with acquired
hemophilia caused by antibodies to Factor VIII (FVIII), a very rare and
potentially life-threatening acute bleeding disorder. Buy Nizoral (Ketoconazole) Following this
positive opinion, the European Commission is expected to make a decision
on the application later this year. Buy Kamagra Effervescent (Sildenafil Citrate) without prescription Upon approval in Europe, OBIZUR will
be the first recombinant porcine FVIII treatment available for acquired
hemophilia A, allowing physicians to monitor treatment response by
measuring FVIII activity levels in addition to clinical assessments.
“The marketing authorization anticipated later this year for OBIZUR will
be an important milestone, offering patients with acquired hemophilia A
in Europe a treatment option that transforms their care by allowing
physicians to monitor treatment response,” said John Orloff, M.D., head
of Research & Development and chief scientific officer, Baxalta. About Mircette (Desogestrel / Ethinyl estradiol) with free prescription “The
positive support by the European regulators reflects the value this
therapy can provide to patients, and supports Baxalta’s long-standing
commitment to addressing unmet needs and reducing the global burden of
bleeding disorders.”
The CHMP positive opinion is based on a global, prospective, controlled,
multi-center Phase II/III open-label clinical trial that examined the
efficacy of OBIZUR in the treatment of serious bleeding episodes in
adults with acquired hemophilia A (29 patients evaluated for safety, 28
evaluated for efficacy). About Dosan with free Rx All patients treated with OBIZUR (28/28) showed
a positive response (bleeding stopped or reduced) and clinical
improvement, with FVIII activity levels at least greater than 20 percent
at 24 hours after the initial infusion. About Tadacip (Tadalafil) with no prescription Resolution of the initial
bleeding episode was observed in 24 out of 28 (86 percent) of the
patients treated with OBIZUR. Buy Water Bottles online Common adverse reactions observed in
greater than five percent of patients in the clinical trial were
development of inhibitors to porcine FVIII.
OBIZUR is currently approved in the United States and is under
regulatory review in Canada, Switzerland, Australia and Colombia. http://doctorconsult.wordpress.com OBIZUR
was granted orphan-drug designation by the European Commission based on
the classification of acquired hemophilia A as a rare disease and the
potential for the treatment to address an important unmet medical need.
About OBIZUR in Europe
OBIZUR [Antihemophilic Factor (Recombinant), Porcine Sequence] is
indicated for the treatment of bleeding episodes in adults with acquired
haemophilia caused by antibodies to Factor VIII.
OBIZUR is not indicated for the treatment of congenital hemophilia A or
von Willebrand disease.
Important Risk Information for OBIZUR
CONTRAINDICATIONS
OBIZUR should not be used in patients with known anaphylactic reactions
to the active substance, hamster protein, or to any of the excipients.
WARNINGS & PRECAUTIONS
Hypersensitivity
Allergic type hypersensitivity reactions are possible with OBIZUR. The
product contains trace amounts of hamster proteins.
If symptoms of hypersensitivity occur, patients should be advised to
discontinue use of the medicinal product immediately and contact their
physician. Patients should be informed of the early signs of
hypersensitivity reactions including hives, generalised urticaria,
tightness of the chest, wheezing, hypotension, and anaphylaxis.
In case of shock, standard medical treatment for shock should be
implemented.
Development of inhibitory antibodies
Inhibitory antibodies against porcine Factor VIII (measured using a
modification of the Nijmegen variation of the Bethesda assay) were
detected before and after exposure to OBIZUR. Inhibitor titres of up to
29 Bethesda units were recorded at baseline yet subjects responded
positively to OBIZUR. It is recommended that treatment should be based
on clinical judgement and not based on detection of inhibitory
antibodies by the Bethesda assay.
There is a lack of clinical information on the development of inhibitory
antibodies to OBIZUR following repeated administration. Therefore,
OBIZUR must only be administered when considered clinically necessary.
Extensive cutaneous purpura do not necessarily require treatment.
OBIZUR is produced by recombinant DNA technology in baby hamster kidney
cells. Antibodies to baby hamster kidney cell protein were not detected
in subjects either before or after exposure to OBIZUR.
High and sustained Factor VIII activity in blood may predispose to
thromboembolic events. Those with pre-existing cardiovascular disease
and the elderly are at particular risk.
If venous catheterisation is required, the risk of catheter-related
complications such as catheter site thrombosis should be considered.
Factor VIII activity determined by the chromogenic assay is generally
lower than Factor VIII activity determined by the one-stage clotting
assay. Measurement of Factor VIII activity must always be carried out
using the same assay methodology on any one patient. The one-stage assay
is recommended because it has been used in determination of the potency
and the mean recovery rate of OBIZUR.
Sodium content
Each vial contains 4.4 mg (198 mM) sodium per ml of reconstituted
solution.
To be taken into consideration by patients on a controlled sodium diet.
Monitoring Laboratory Tests
Monitor Factor VIII activity and clinical condition 30 minutes after the
first injection and 3 hours after administering OBIZUR.
Monitor Factor VIII activity immediately prior to and 30 minutes after
subsequent doses and refer to the table for recommended target Factor
VIII trough levels.
The one-stage clotting assay for Factor VIII is recommended as it has
been used in determination of the potency of OBIZUR and the mean
recovery rate.
ADVERSE REACTIONS
Common adverse reactions observed in greater than 5% of subjects in the
clinical trial were development of inhibitors to porcine factor VIII.
About Acquired Hemophilia A
Acquired hemophilia A is a rare, potentially life-threatening bleeding
disorder, which, unlike congenital hemophilia, typically affects older
adults and occurs in both males and females1,2. In acquired
hemophilia A, individuals typically experience subcutaneous, soft
tissue, and post-surgical bleeding.2,3,4 The comorbidities in
this typically elderly population also pose a particular challenge to
treat serious bleeding episodes.1
