* Approval based on Phase III trial showing superiority of Tasigna to standard
of care Glivec® in key measures of efficacy, including delay of cancer
progression
* Newly diagnosed patients now have a new medical option; Tasigna also
available in the US and Switzerland with other submissions under review
Basel, December 21, 2010 - Novartis has received approval from Japan's Ministry
of Health, Labour and Welfare to offer Tasigna(®) (nilotinib) as a treatment for
adult patients with newly diagnosed Philadelphia chromosome-positive chronic
myeloid leukemia (Ph+ CML) in chronic phase.
The approval is based on positive findings from a pivotal Phase III trial
demonstrating superiority to the standard of care Glivec(® )(imatinib)* in
achieving molecular and cytogenetic response and delaying cancer progression.
These data were first published in the June 17 issue of The New England Journal
of Medicine[1] and were confirmed by 18-month median follow-up data presented at
the 46(th) American Society of Clinical Oncology (ASCO) annual meeting held in
June[2].
The US Food and Drug Administration (FDA) and Swissmedic have also approved
Tasigna in this first-line indication. Regulatory submissions are under review
in other countries worldwide.
"The approval of Tasigna for newly diagnosed Ph+ CML patients in chronic phase
illustrates the Novartis commitment to continue challenging and advancing the
science for treating cancer," said Hervé Hoppenot, President, Novartis Oncology.
"Tasigna was developed because we believed we could improve upon the standard of
care to meet patients' unmet needs, and as a result, patients now have a new and
effective option for the treatment of CML."
In laboratory studies, Tasigna has been shown to be a potent and selective
inhibitor of the Bcr-Abl protein that causes production of cancer cells in Ph+
CML[3],[4]. It is also active against a broad spectrum of Bcr-Abl mutations
associated with resistance to Glivec[5].
In its pivotal head-to-head trial, Tasigna surpassed Glivec in key measures of
treatment efficacy, as has been previously reported. Tasigna eliminated Bcr-Abl
faster and more deeply than Glivec and resulted in lower rates of cancer
progression after 12 months of therapy[1]ajor molecular response (MMR), a
measure of deep reduction in Bcr-Abl, is considered to be a critical therapeutic
milestone associated with good long-term outcomes for patients with Ph+ CML in
chronic phase[6-8]. Treatment with Tasigna led to higher rates of both MMR and
complete cytogenetic response (CCyR) (undectable Philadelphia chromosome that is
the hallmark of this cancer) compared with Glivec[1].
After a median of 18 months of follow-up treatment, two patients on the Tasigna
300 mg twice daily arm progressed to either accelerated phase or blast crisis
while 17 patients on the Glivec arm progressed to either accelerated phase or
blast crisis. In the study, Tasigna and Glivec were well tolerated. Fewer
patients discontinued due to adverse events from the Tasigna 300 mg twice daily
arm of the study compared to the Glivec 400 mg once daily arm.
The randomized, open-label, multicenter trial called ENESTnd (Evaluating
Nilotinib Efficacy and Safety in Clinical Trials of Newly Diagnosed Ph+ CML
Patients), compared the efficacy and safety of Tasigna versus Glivec in adult
patients with newly diagnosed Ph+ CML in chronic phase[1]. It is the largest
global randomized comparison of two oral therapies ever conducted in newly
diagnosed Ph+ CML patients in chronic phase.
This year, Novartis also began a collaboration with molecular diagnostics
company Cepheid to develop a new FDA cleared/approved Bcr-Abl test, which
adheres to the International Scale. The goal of the collaboration is to help
doctors more reliably monitor Ph+ CML patients. Cepheid and Novartis also will
develop a next generation test, which is expected to enable even more sensitive
testing, indicating the depth of a patient's response to tyrosine kinase
inhibitors, including Tasigna and Glivec. Currently, there are no FDA
cleared/approved tests to monitor for Bcr-Abl.
About Tasigna[3]
Tasigna is indicated for the treatment of adult patients with newly diagnosed
Philadelphia chromosome-positive chronic myelogenous leukemia (CML) in the
chronic phase.
Tasigna has also been approved in over 90 countries for the treatment of chronic
phase (CP) and accelerated phase Ph+ CML in adult patients resistant or
intolerant to at least one prior therapy, including Glivec. The effectiveness of
Tasigna for this indication is based on confirmed hematologic and unconfirmed
cytogenetic response rates. There are no controlled trials demonstrating a
clinical benefit, such as improvement in disease-related symptoms or increased
survival.
Tasigna is not approved in the EU for the treatment of newly diagnosed Ph+ CML-
CP.
Tasigna important safety information
Tasigna should be taken twice daily at an interval of approximately 12 hours
apart and must not be taken with food. No food should be consumed for two hours
before the dose and for at least one hour after the dose. Avoid grapefruit juice
and other foods that are known to inhibit CYP3A4.
Tasigna should not be used in patients who are hypersensitive to nilotinib or
any of the excipients.
Treatment with Tasigna has been associated with hematological side effects such
as thrombocytopenia, neutropenia and anemia, which was generally reversible and
usually managed by withholding Tasigna temporarily or dose reduction. Complete
blood counts should be performed every two weeks for the first two months and
then monthly thereafter as clinically indicated.
Tasigna should be used with caution in patients with uncontrolled or significant
cardiac disease (e.g., recent heart attack, congestive heart failure, unstable
angina or clinically significant bradycardia), as well as in patients who have
or may develop prolongation of QTc. These include patients with abnormally low
potassium or magnesium levels, patients with congenital long QT syndrome,
patients taking anti-arrhythmic medicines or other drugs that may lead to QT
prolongation. Low levels of potassium or magnesium must be corrected prior to
Tasigna administration. Close monitoring for an effect on the QTc interval is
advisable and a baseline electrocardiography is recommended prior to initiating
therapy with Tasigna and as clinically indicated. Uncommon cases (0.1 to 1%) of
sudden death have been reported in clinical studies in patients with significant
risk factors.
Tasigna should be used with caution in patients with liver impairment, in
patients with a history of pancreatitis and in patients with total gastrectomy.
Patients with rare hereditary problems of galactose intolerance, severe lactase
deficiency or glucose-galactose malabsorption should not use Tasigna. Tasigna
should not be used during pregnancy unless clearly necessary and breast feeding
is not recommended during treatment.
The most frequent Grade 3 or 4 adverse events for Tasigna were primarily
hematological in nature and included neutropenia and thrombocytopenia.
Elevations seen in bilirubin, liver function tests, lipase enzymes and blood
sugar were mostly transient and resolved over time. These cases were easily
managed and rarely led to discontinuation of treatment. Pancreatitis was
reported in less than 1% of cases. The most frequent non-hematologic drug-
related adverse events were rash, pruritus, nausea, fatigue, headache, alopecia,
myalgia, constipation and diarrhea. Most of these adverse events were mild to
moderate in severity.
About Glivec[9]
Glivec is approved in more than 110 countries, including the US, EU and Japan,
for the treatment of all phases of Ph+ CML. Glivec is also approved in the US,
EU and other countries for the treatment of patients with Kit (CD117)-positive
gastrointestinal tumors (GIST), which cannot be surgically removed and/or have
already spread to other parts of the body (metastasized). In the US and EU,
Glivec is now approved for the post-surgery treatment of adult patients
following complete surgical removal of Kit (CD117)-positive gastrointestinal
stromal tumors. In the EU, Glivec is also approved for the treatment of adult
patients with newly diagnosed Ph+ acute lymphoblastic leukemia (Ph+ ALL) in
combination with chemotherapy and as a single agent for patients with relapsed
or refractory Ph+ ALL. Glivec is also approved for the treatment of adult
patients with unresectable, recurrent and/or metastatic dermatofibrosarcoma
protuberans (DFSP) who are not eligible for surgery. Glivec is also approved for
the treatment of patients with myelodysplastic/myeloproliferative diseases
(MDS/MPD). Glivec is also approved for hypereosinophilic syndrome and/or chronic
eosinophilic leukemia (HES/CEL).
The effectiveness of Glivec is based on overall hematological and cytogenetic
response rates and progression-free survival in CML, on hematological and
cytogenetic response rates in Ph+ ALL, MDS/MPD, on hematological response rates
in systemic mastocytosis (SM), HES/CEL, on objective response rates and
progression-free survival in unresectable and/or metastatic GIST, on recurrence
free survival in adjuvant GIST and on objective response rates in DFSP.
Increased survival in controlled trials has been demonstrated only in newly
diagnosed chronic phase CML and GIST.
Not all indications are available in every country.
Glivec important safety information
The majority of patients treated with Glivec in clinical trials experienced
adverse events at some time. Most events were of mild to moderate grade and
treatment discontinuation was not necessary in the majority of cases.
The safety profile of Glivec was similar in all indications. The most common
side effects included nausea, superficial edema, muscle cramps, skin rash,
vomiting, diarrhea, abdominal pain, myalgia, arthralgia, hemorrhage, fatigue,
headache, joint pain, cough, dizziness, dyspepsia and dyspnea, dermatitis,
eczema and fluid retention, as well as neutropenia, thrombocytopenia and anemia.
Glivec was generally well tolerated in all of the studies that were performed,
either as monotherapy or in combination with chemotherapy, with the exception of
a transient liver toxicity in the form of transaminase elevation and
hyperbilirubinemia observed when Glivec was combined with high dose
chemotherapy.
Rare/serious adverse reactions include: sepsis, pneumonia, depression,
convulsions, cardiac failure, thrombosis/embolism, ileus, pancreatitis, hepatic
failure, exfoliative dermatitis, angioedema, Stevens-Johnson syndrome, renal
failure, fluid retention, edema (including brain, eye, pericardium, abdomen and
lung), hemorrhage (including brain, eye, kidney and gastrointestinal tract),
diverticulitis, gastrointestinal perforation, tumor hemorrhage/necrosis and hip
osteonecrosis/avascular necrosis.
Patients with cardiac disease or risk factors for cardiac failure should be
monitored carefully and any patient with signs or symptoms consistent with
cardiac failure should be evaluated and treated. Cardiac screening should be
considered in patients with HES/CEL, and patients with MDS/MPD with high level
of eosinophils (echocardiogram, serum troponin level).
Glivec is contraindicated in patients with known hypersensitivity to imatinib or
any of its excipients. Women of childbearing potential should be advised to
avoid becoming pregnant while taking Glivec.
