IntelGenx Announces Commercial Launch of Forfivo XL(TM) in USA
Saint Laurent, Quebec--(Newsfile Corp. - October 9, 2012) -
IntelGenx Corp. (TSX-V: IGX) (OTCQX: IGXT) ("IntelGenx", “the Company”) today announced that Forfivo XL™ is now available by prescription in the USA.
Forfivo XL™ is indicated for treatment of Major Depressive Disorder (MDD) and is the only extended-release bupropion HCl product to provide a once-daily, 450mg dose in a single tablet. The active ingredient in Forfivo XL is bupropion, the same
active ingredient used in the well-known antidepressant product: Wellbutrin XL®. Until now, most patients in the US requiring a 450mg dose of bupropion have been taking multiple tablets to achieve their 450mg dose requirement. With Forfivo
XL™ now available in the US, these patients can simplify their dosing regimen to a single Forfivo XL tablet, once-daily.
“Until today, physicians in the US treating their MDD patients with high-dose bupropion have had to use multiples of the lower strength, 150mg and 300mg, products. With the US commercial launch of Forfivo XL, physicians can now prescribe a
simpler and more convenient single-pill 450mg dose of bupropion to better meet the needs of their MDD patients” said Dr. Horst G. Zerbe, President and CEO of IntelGenx. “We feel that the combination of market need and the targeted
marketing approach applied by our commercial partner Edgemont Pharmaceuticals will make Forfivo XL a successful product.
Forfivo XL™ was developed by IntelGenx and is the Company’s first FDA approved product, approved by the FDA on November 10, 2011. Forfivo XL™ is being marketed in the United States under the terms of a license agreement between
IntelGenx and Edgemont Pharmaceuticals. The commercialization of Forfivo XL™ triggers launch-related milestone payments for IntelGenx of up to $4.0 million, and additional milestones upon achieving certain sales and exclusivity targets of
up to a further $23.5 million. IntelGenx will also receive tiered double-digit royalties on net sales of Forfivo XL™.
Important Safety Information for Forfivo XL
WARNING: SUICIDALITY and ANTIDEPRESSANT DRUGS; PSYCHIATRIC EVENTS and SMOKING CESSATION SUICIDALITY and ANTIDEPRESSANT DRUGS: Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder
(MDD) and other psychiatric disorders. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual
changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. FORFIVO XL is not approved for use in pediatric patients.
PSYCHIATRIC EVENTS and SMOKING CESSATION: FORFIVO XL is not approved for smoking cessation treatment, but bupropion under the name ZYBAN ® is approved for this
use. Serious neuropsychiatric events, including but not limited to depression, suicidal ideation, suicide attempt, and completed suicide have been reported in patients taking bupropion for smoking cessation. Advise patients and caregivers that the
patient using bupropion for smoking cessation should stop taking bupropion and contact a healthcare provider immediately if agitation, hostility, depressed mood, or changes in thinking or behavior that are not
typical for the patient are observed, or if the patient develops suicidal ideation or suicidal behavior.
FORFIVO XL is contraindicated in:
Seizure disorder, because these patients may have a lower seizure threshold
Patients treated currently with other bupropion products, because seizure incidence is dose-dependent
A current or prior diagnosis of bulimia or anorexia nervosa
Patients undergoing abrupt discontinuation of alcohol or sedatives
Concurrent administration of monoamine oxidase (MAO) inhibitors. At least 14 days should elapse between discontinuation of an MAO inhibitor and initiation of treatment with FORFIVO XL.
Known hypersensitivity to bupropion or the other ingredients of FORFIVO XL
WARNINGS AND PRECAUTIONS
Activation of Mania/Hypomania A major depressive episode may be the initial presentation of bipolar disorder. Prior to initiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened to
determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. It should be noted that FORFIVO XL is not approved for use in
treating bipolar depression. Seizures Bupropion is associated with a dose-related risk of seizures. The risk of seizures is also related to patient factors, clinical situations, and concomitant medications, which must be considered in selection of
patients for therapy with FORFIVO XL. FORFIVO XL should be discontinued and not restarted in patients who experience a seizure while on treatment. Retrospective analysis of clinical experience gained during the development of bupropion suggests that
the risk of seizure may be minimized if the total daily dose of bupropion does not exceed 450 mg and the rate of incrementation of the bupropion dose is gradual. Psychosis and Other Neuropsychiatric Events Depressed patients treated with bupropion
have been reported to show a variety of neuropsychiatric signs and symptoms, including delusions, hallucinations, psychosis, concentration disturbance, paranoia, and confusion. In some cases, these symptoms abated upon dose reduction and/or
withdrawal of treatment. It is recommended stopping bupropion when the symptoms occur. Severe Hypertension In clinical practice, hypertension, in some cases severe, requiring acute treatment, has been reported in patients receiving bupropion alone
and in combination with nicotine replacement therapy. These reactions have been observed in both patients with and without evidence of preexisting hypertension. Monitoring of blood pressure is recommended in patients who receive the combination of
bupropion and nicotine replacement. Agitation and Insomnia Increased restlessness, agitation, anxiety, and insomnia, especially shortly after initiation of treatment, have been associated with treatment with bupropion. In clinical studies of MDD,
these symptoms (see Table 2 of the full prescribing information) were sometimes of sufficient magnitude to require treatment with sedative/hypnotic drugs. Symptoms in these studies were sufficiently severe to require discontinuation of treatment in
1% and 2.6% of patients treated with 300 and 400 mg/day, respectively, of bupropion hydrochloride sustained-release tablets and 0.8% of patients treated with placebo. Altered Appetite and Weight In placebo-controlled short-term studies of MDD using
the sustained-release formulation of bupropion hydrochloride, patients experienced weight gain or weight loss (see Table 3 of the full prescribing information). In studies conducted with the immediate-release formulation of bupropion hydrochloride,
35% of patients receiving tricyclic antidepressants gained weight, compared to 9% of patients treated with the immediate-release formulation of bupropion hydrochloride. If weight loss is a major presenting sign of a patient’s depressive
illness, the anorectic and/or weight-reducing potential of FORFIVO XL tablets should be considered. Hypersensitivity Reactions Anaphylactoid/anaphylactic reactions characterized by symptoms such as pruritus, urticaria, angioedema, and dyspnea
requiring medical treatment have been reported in clinical trials with bupropion. In addition, there have been rare spontaneous postmarketing reports of erythema multiforme, Stevens-Johnson syndrome, and anaphylactic shock associated with bupropion.
A patient should stop taking FORFIVO XL and consult a doctor if experiencing allergic or anaphylactoid/anaphylactic reactions (e.g., skin rash, pruritus, hives, chest pain, edema, and shortness of breath) during treatment. Arthralgia, myalgia, and
fever with rash and other symptoms suggestive of delayed hypersensitivity have been reported in association with bupropion. These symptoms may resemble serum sickness [see Contraindications in the full
Clinical Trials Experience: Commonly Observed Adverse Reactions in Controlled Clinical Trials The most common adverse reactions were (incidence ≥ 5%; ≥ 2 times placebo rate): Dry mouth, nausea, insomnia, dizziness, pharyngitis, abdominal pain, agitation, anxiety, tremor, palpitation, sweating, tinnitus, myalgia, anorexia, urinary frequency, and rash.
