Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The safety population consisted of a total of 978 Parkinson's disease patients who received at least one dose of Prikap, and had an average duration of exposure of 40 weeks.

Adverse Reactions In Early Parkinson's Disease

In a placebo-controlled clinical study in patients with early Parkinson's disease (Study 1), the most common adverse reactions with Prikap (in at least 5% of patients and more frequently than in placebo) were nausea, dizziness, headache, insomnia, abnormal dreams, dry mouth, dyskinesia, anxiety, constipation, vomiting, and orthostatic hypotension.

Table 2 lists adverse reactions occurring in at least 5% of Prikap-treated patients and at a higher rate than placebo in Study 1.

Adverse Reactions Leading to Discontinuation in Study 1

In Study 1, 12% of patients discontinued Prikap early due to adverse reactions; a higher proportion of patients in the 61.25 mg / 245 mg Prikap-treated group (14%) and in the 97.5 mg / 390 mg Prikap-treated group (15%) experienced adverse reactions leading to early discontinuation compared to (4%) in the placebo group. The most common adverse reactions resulting in early discontinuation were nausea, dizziness, and vomiting.

Adverse Reactions In Advanced Parkinson's Disease

In an active-controlled clinical study in patients with advanced Parkinson's disease (Study 2), the most common adverse reactions with Prikap that occurred during dose conversion or maintenance (in at least 5% of patients and more frequently than on oral immediate-release Carbidopa (Prikap)-Levodopa (Prikap)) were nausea and headache.

Table 3 lists adverse reactions occurring in at least 5% of Prikap-treated patients and at a higher rate than oral immediate-release Carbidopa (Prikap)-Levodopa (Prikap) in Study 2.

Table 3: Adverse Reactions in Study 2 in Patients with Advanced Parkinson's Disease

Period	Prikap (N=201)	Immediate-Release Carbidopa (Prikap)-Levodopa (Prikap) (N=192)
Dose Convers ion*	Maintenance	Dose Convers ion*	Maintenance
%	%	%	%
Nausea	4	3	6	2
Headache	5	1	3	2
*All patients were converted to Prikap in the open label Dose Conversion period and then received randomized treatment during maintenance.

Adverse Reactions Leading to Discontinuation in Study 2

In Study 2, 5% of patients discontinued treatment due to adverse reactions during conversion to Prikap. The common adverse reactions leading to discontinuation during dose conversion were dyskinesia, anxiety, dizziness, and on and off phenomenon.

What is the most important information I should know about Prikap?

• Prikap may cause drowsiness, dizziness, or light-headedness. These effects may be worse if you take it with alcohol or certain medicines. Use Prikap with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
• Check with your doctor before you drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Prikap; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
• Prikap may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
• Tell your doctor or dentist that you take Prikap before you receive any medical or dental care, emergency care, or surgery.
• NMS is a possibly fatal syndrome that can be caused by Prikap. Symptoms may include fever; stiff muscles; confusion; abnormal thinking; fast or irregular heartbeat; and sweating. Contact your doctor at once if you have any of these symptoms.
• Some patients who take Prikap have reported suddenly falling asleep while performing daily activities (eg, driving, eating, talking). Some patients did not experience drowsiness and felt that they were alert immediately before suddenly falling asleep. Some of these events have been reported as late as 1 year after Prikap was started. Use caution when driving, operating machinery, or performing other activities that could be dangerous. Inform your doctor if you experience unusual drowsiness or sleepiness while using Prikap.
• Patients with Parkinson disease may have an increased risk of developing a certain type of skin cancer (melanoma). It is not known if Prikap also increases the risk of melanoma. You may need to have skin exams while you are using Prikap. Tell your doctor if you notice any unusual skin growths or a change in the appearance of a mole. Discuss any questions or concerns with your doctor.
• Some people have experienced new, unusual, or increased urges (eg, gambling, sexual urges) while taking Prikap. Tell your doctor right away if you notice such effects.
• Diabetes patients - Prikap may cause the results of some tests for urine glucose or urine ketones to be wrong. Ask your doctor before you change your diet or the dose of your diabetes medicine.
• Do not suddenly stop taking Prikap. Some conditions may become worse when Prikap is suddenly stopped. Your dose may need to be slowly lowered by your doctor to avoid side effects.
• Gradually increase physical activity as your symptoms improve.
• A dark color (red, brown, or black) may appear in your saliva, urine, or sweat after taking Prikap. This is not harmful.
• The effects of Prikap might start to wear off between doses. Talk with your doctor if Prikap stops working well or if your condition worsens.
• Prikap may affect certain lab test results. Make sure your doctors and lab personnel know you take Prikap.
• Lab tests, including complete blood cell counts and liver function, may be performed while you use Prikap. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
• Use Prikap with caution in the ELDERLY; they may be more sensitive to its effects.
• Prikap should not be used in CHILDREN; safety and effectiveness in children have not been confirmed.
• PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of taking Prikap while you are pregnant. It is not known if Prikap is found in breast milk. If you are or will be breast-feeding while you are taking Prikap, check with your doctor. Discuss any possible risks to your baby.

Prikap contraindications

Nonselective monoamine oxidase (MAO) inhibitors are contraindicated for use with Prikap orally disintegrating tablets. These inhibitors must be discontinued at least two weeks prior to initiating therapy with Prikap orally disintegrating tablets. Prikap orally disintegrating tablets may be administered concomitantly with the manufacturer’s recommended dose of an MAO inhibitor with selectivity for MAO type B (e.g., selegiline HCI).

Prikap orally disintegrating tablets are contraindicated in patients with known hypersensitivity to any component of this drug, and in patients with narrow-angle glaucoma.

Because Levodopa (Prikap) may activate a malignant melanoma, Prikap orally disintegrating tablets should not be used in patients with suspicious, undiagnosed skin lesions or a history of melanoma.
