Court
Backs Experimental Drugs for Dying Patients

Terminally ill patients have a constitutional right to obtain
experimental drugs before the Food and Drug Administration has
decided whether to approve them, a federal appeals court ruled
yesterday.
Saying that dying patients have a basic "right of self-preservation,"
the court held that drugs that have passed the first phase of
FDA review -- which determines whether a product is safe -- should
be made available if they might save someone's life.
The 2 to 1 decision by the U.S. Court of Appeals for the District
of Columbia Circuit overturned a lower court's ruling. The judges
sent the case back to the district court for a full hearing and
possibly a trial.
The case was brought by the Abigail Alliance for Better Access
to Developmental Drugs -- which advocates making experimental
drugs available earlier to dying patients -- and was argued by
the Washington Legal Foundation, a public interest law firm that
has frequently challenged regulatory agencies.
The appeals court found that "barring a terminally ill patient
from the use of a potentially life saving treatment impinges on
this right of self-preservation." It also agreed with the
alliance that the Supreme Court's 1990 decision establishing a
"right to die" in the case of Nancy Cruzan, a brain-dead
Missouri woman who was ultimately disconnected from life support,
applied in reverse in this case.
"If there is a protected liberty interest in self-determination
that includes a right to refuse life-sustaining treatment, even
though this will hasten death, then the same liberty interest
must include the complementary right of access to potentially
life-sustaining medication, in light of the explicit protection
accorded 'life,' " Judge Judith W. Rogers wrote.
Judge Thomas B. Griffith dissented, saying that the ruling goes
against the "expressed rule" of Congress and the president.
"The majority's approach injects courts into unknown questions
of science and medicine," he wrote.
In its opposition to the challenge, the FDA had said that the
agency already has programs that make potentially lifesaving drugs
available before final approval. In addition, it said that allowing
large numbers of patients to take unapproved drugs could put many
at unacceptable risk, even if they are terminally ill.
"We remain sympathetic to the desire of terminally ill patients
to gain access to experimental treatments when they have exhausted
other therapeutic options, and are exploring a number of new efforts
to improve how we make investigational drugs available through
expanded access programs," said Scott Gottlieb, deputy commissioner
for medical and scientific affairs.
The Arlington-based Abigail Alliance was founded in 2001 by Frank
Burroughs, whose 21-year-old daughter died of cancer. The family
had tried to enroll her in a number of clinical trials of promising
cancer medications but was rebuffed, and Burroughs decided to
continue his fight to expand access to experimental drugs after
her death. He said several of the potentially lifesaving drugs
that his group sought to make available while they were still
under regulatory review went on to be approved and widely used.
Burroughs said yesterday that he hopes the FDA will work with
his group and others to make unapproved drugs more easily available
to dying patients.
The alliance has sought access to medications that have passed
Phase I of the FDA review, which generally involves studies of
20 to 80 patients and results in a determination of whether the
drug is safe enough for further human testing. Phase II trials
determine whether a drug is effective, and Phase III studies involve
larger groups and give a better sense of whether a drug is safe
and useful.

Research Institute Receives Orphan Drug Designation for Antineoplastons
A10 and AS2-1 for Treatment of Brain Stem Glioma
Houston,
TX, September 7, 2004 – Burzynski Research Institute (BRI)
(OTCBB:BZYR) announced today that the U.S. Food and Drug Administration
(FDA) has granted orphan drug designation for its drug candidates
Antineoplastons A10 and AS2-1 for the treatment of brain stem
glioma.
The FDA’s
orphan drug program is intended to encourage research, development
and approval of products for diseases that affect fewer than 200,000
patients in the United States per year and provide a significant
therapeutic advantage over existing treatments. If Antineoplastons
A10 and AS2-1 receive approval from the FDA, orphan drug designation
will provide Antineoplastons A10 and AS2-1 with seven years of
market exclusivity following such regulatory approval. The designation
also enables BRI to apply for clinical research funding, tax credits
on clinical research and development expenses, a potential waiver
of user fees associated with filing the marketing application
and assistance from the Office of Orphan Product Development (OOPD)
in guiding the drug through the regulatory approval process.
"We
are pleased to receive the FDA's orphan drug designation for Antineoplastons
A10 and AS2-1, an important step toward bringing this treatment
to market" said Luke E. Lawson, Ph.D., Director of Regulatory
Affairs of BRI. "Therapeutic options for brain stem glioma
patients are rather limited. We are committed to accelerating,
wherever possible, our efforts to help address the unmet medical
need of these patients worldwide."
Burzynski
Research Institute is a biopharmaceutical company committed to
developing medicines for serious and life threatening diseases
from genomics and naturally occurring compounds. Research and
development efforts are focused on antineoplastons, autoimmune
disease and HIV.
Dr.
Robert Burdick Review
Seattle-area
oncologist Dr. Robert Burdick reviewed the records of several
of Dr. Burzynski's patients with brain tumors. His report states
that the responses seen can only be attributed to treatment with
antineoplastons.

Clinical
Trials Data
- - - Results
of Brain Tumor Trials - - -
(as of November
2001)
Over 100 clinical
trials using different chemotherapy regimens have been conducted
on recurrent brain tumors. The general consensus is that such
tumors cannot be cured by chemotherapy, and the response rate
is only modest. Complete responses are almost never seen, and
the total response rate usually includes stable disease. Even
though some of these studies report significant responses, the
durations of improvement are short. Ultimately, almost all of
these patients die from their brain tumors. Patients who are being
treated with antineoplaston therapy often are the exception.
Antineoplastons
have been used to treat neoplastic disease since the 1970s. Patients
can tolerate administration of antineoplastons very well, for
as long as approximately 10 years in one case.
The Burzynski
Research Institute currently sponsors 72 different Phase II clinical
trials with Antineoplastons A10 and AS2-1 in different forms of
cancer. Five of these trials have reached the final point and
proved antincancer activity in various types of malignant brain
tumors.

Adverse Reactions
to High-Dose Treatment
Almost all
patients experience increased urine output and slight thirst.
The treatment usually is free from adverse reactions or is associated
with mild side effects. Moderate side effects (Grade 2 by NCI
criteria) include fluid retention, hypernatremia, hypocalcemia,
hypokalemia, hypomagnesemia, nausea and vomiting, elevation of
SGPT, leukopenia, allergic skin rash, fever, chills, headache,
tinnitus and decreased hearing, decreased and blurred vision.
Serious adverse
reactions (Grades 3 and 4 by NCI criteria) were observed in only
a small number of cases and included high serum sodium levels
(0.9%); low calcium levels (0.6%); low magnesium levels (0.3%);
low potassium levels (0.3%); elevations of serum bilirubin (0.3%),
SGOT (0.2%), and SGPT (0.3%); and thrombocytopenia (1.1%). It
is suspected that in many cases, neurologic toxicity, visual toxicity,
and ototoxicity resulted from the brain tumors. Serious thrombocytopenia
occurred in only one patient who received combination chemotherapy
6 weeks before administration of antineoplastons, which could
have contributed to bone marrow suppression. Generally, adverse
reactions were fully reversible.
NOTE: Most
patients who come to Dr. Burzynski already have failed at least
one type of therapy and many have failed more than one type. Many
of these patients are considered to be in the final stages of
cancer and have no remaining conventional treatment options available
to them.
