MARLBOROUGH – Sunovion Pharmaceuticals Inc.announced last week KYNMOBI™ (apomorphine HCI) sublingual film is now available in the U.S. by prescription for the acute, intermittent treatment of OFF episodes in patients with Parkinson’s disease (PD).

KYNMOBI is a novel thin film formulation of apomorphine that dissolves under the tongue to treat OFF episodes in patients with PD as they occur. KYNMOBI was approved by the U.S. Food and Drug Administration (FDA) on May 21, 2020 and its commercial activities initiated on September 29, 2020.

“People living with Parkinson’s disease can potentially spend hours each day navigating disruptions caused by OFF episodes, which may result in reduced motor function and present challenges performing daily activities,” said Thomas Gibbs, SVP, Chief Commercial Officer at Sunovion. “OFF episodes can make simple tasks, like getting dressed in the morning, nearly impossible. We are pleased that patients, their care partners and physicians now have access to KYNMOBI to help control these debilitating OFF episodes.”

In a Phase 3 clinical trial, people with PD treated with KYNMOBI experienced significant improvements in motor symptoms at 30 minutes after dosing at week 12, compared to placebo, with numerical improvements seen at 15 minutes post-administration. Interim data from an open-label Phase 3 extension study recently presented at the International Parkinson and Movement Disorder Society (MDS) Virtual Congress 2020 support KYNMOBI’s long-term efficacy, safety and tolerability in up to 48-weeks of patient use.

“Reduced mobility associated with OFF episodes can be one of the most troubling and burdensome aspects for people living with Parkinson’s disease,” said Stuart Isaacson, M.D., Director, Parkinson’s Disease and Movement Disorders Center of Boca Raton. “This is intensified as Parkinson’s disease progresses and OFF episodes become more frequent. The availability of KYNMOBI provides a new, effective on-demand treatment option that we can offer patients to use as needed for OFF episodes when they occur.”

KYNMOBI (apomorphine hydrochloride) sublingual film, a novel formulation of apomorphine, a non-ergoline dopamine agonist, is the first and only sublingual therapy for the fast-acting, on-demand treatment of OFF episodes associated with Parkinson’s disease. KYNMOBI may be used up to five times a day.

Phase 3 clinical trial results, published in Lancet Neurology, demonstrated that patients with PD receiving KYNMOBI experienced significant improvements in motor symptoms at 30 minutes after dosing at week 12, with a mean reduction of 7.6 points, compared to placebo, on the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) Part III score. Separation at placebo was seen as early as 15 minutes post-dose (first time point measured) and persisted up to 90 minutes (last time point measured). Additionally, a significantly higher percentage of people treated with KYNMOBI had a patient-rated full ON response within 30 minutes at week 12, compared with people receiving placebo. KYNMOBI was generally well-tolerated. Among the most frequently reported treatment-emergent adverse events in this study (occurring in more than 5 percent of patients and at a rate greater than placebo) were nausea, oropharyngeal reactions, somnolence and dizziness.

KYNMOBITM (apomorphine hydrochloride) sublingual film is a prescription medicine used to treat short-term (acute), intermittent “off” episodes in people with Parkinson’s disease (PD).

It is not known if KYNMOBI is safe and effective in children. Patients are advised not to take KYNMOBI if you are taking certain medicines to treat nausea called 5HT3 antagonists, including ondansetron, granisetron, dolasetron, palonosetron, and alosetron. People taking ondansetron together with apomorphine, the active ingredient in KYNMOBI, have had very low blood pressure and lost consciousness or “blacked out.”

Patients are advised not to take KYNMOBI if you are allergic to apomorphine hydrochloride or to any of the ingredients in KYNMOBI. KYNMOBI also contains a sulfite called sodium metabisulfite. Sulfites can cause severe, life‐threatening allergic reactions in some people. An allergy to sulfites is not the same as an allergy to sulfa. People with asthma are more likely to be allergic to sulfites. Call your healthcare provider if you have hives, itching, rash, swelling of the lips, tongue and mouth, redness of your face (flushing), throat tightness, trouble breathing or swallowing.

Before starting KYNMOBI, tell your healthcare provider:

About all of your medical conditions, including if you:

● have difficulty staying awake during the daytime ● have liver problems
● have dizziness ● have kidney problems
● have fainting spells ● have heart problems
● have low blood pressure ● have had a stroke or other brain problems
● have asthma ● have a mental problem called a major psychotic disorder
● are allergic to any medicines containing sulfites ● drink alcohol
● are pregnant or plan to become pregnant. It is not known if KYNMOBI will harm your unborn baby.
● are breastfeeding or plan to breastfeed. It is not known if KYNMOBI passes into your breast milk.

Tell your healthcare provider about all the medicines you take, including:

● prescription medicines ● over-the-counter medicines
● vitamins ● herbal supplements

KYNMOBI may affect the way other medicines work, and other medicines can affect how KYNMOBI works. Taking KYNMOBI with other medicines may cause serious side effects. If you take nitroglycerin under your tongue (sublingual) while using KYNMOBI, your blood pressure may decrease and cause dizziness. You should lie down before and after taking sublingual nitroglycerin.

KYNMOBI can cause serious side effects, including:

  • nausea and vomiting. Nausea is a common side effect of KYNMOBI. Nausea and vomiting can happen with KYNMOBI. Your healthcare provider may prescribe a medicine called an antiemetic, such as trimethobenzamide to help prevent nausea and vomiting.
  • sleepiness or falling asleep during the day. Sleepiness is a serious, and common side effect of KYNMOBI. Some people treated with KYNMOBI may get sleepy during the day or fall asleep without warning while doing everyday activities such as talking, eating, or driving a car.
  • dizziness. Dizziness is a serious, and common side effect of KYNMOBI. KYNMOBI may lower blood pressure and cause dizziness. Dizziness can happen when KYNMOBI treatment is started or when the KYNMOBI dose is increased. Do not get up too fast from sitting or after lying down, especially if you have been sitting or lying down for a long period of time.
  • mouth (oral) irritation. Mouth (oral) irritation is a common side effect of KYNMOBI. You should call your healthcare provider if you develop any of these signs or symptoms:
 rednessmouth sores (ulceration)dryness of the mouth, lips or tongue
 swellingpainpain with swallowing
  • falls. The changes that can happen with PD, and the effects of some PD medicines, can increase the risk of falling. KYNMOBI may also increase your risk of falling.
  • hallucinations or psychotic-like behavior. KYNMOBI may cause or make psychotic-like behavior worse including hallucinations (seeing or hearing things that are not real), confusion, excessive suspicion, aggressive behavior, agitation, delusional beliefs (believing things that are not real), and disorganized thinking.
  • strong (intense) urges. Some people with PD have reported new or strong uncontrollable urges to gamble, increased sexual urges, increased urges to spend money (compulsive shopping), and other intense urges, while taking PD medicines, including KYNMOBI. If you or your family members notice that you have strong urges, talk to your healthcare provider. The strong urges may go away if your KYNMOBI dose is lowered or stopped.
  • high fever and confusion. KYNMOBI may cause a problem that can happen in people who suddenly lower their dose, stop using, or change their dose of KYNMOBI. Symptoms include:
 very high feverconfusion
 stiff muscleschanges in breathing and heartbeat

Do not stop taking KYNMOBI or change your dose unless you are told to do so by your healthcare provider.

  • heart problems. If you have shortness of breath, fast heartbeat, chest pain, or feel like you are going to pass out (faint) while taking KYNMOBI, call your healthcare provider or get emergency help right away.
  • tissue changes (fibrotic complications). Some people have had changes in the tissues of their pelvis, lungs, and heart valves when taking medicines called nonergot derived dopamine agonists like KYNMOBI.
  • prolonged painful erections (priapism). KYNMOBI may cause prolonged, painful erections in some people. If you have a prolonged and painful erection, you should call your healthcare provider or go to the nearest hospital emergency room right away.

The most common side effects of KYNMOBI include:

 sleepinessmouth swelling, pain or sores

By 2030, it is estimated that 1.2 million people in the U.S. and an estimated 10 million people worldwide will be living with Parkinson’s disease (PD).2 PD is a chronic, progressive neurodegenerative disease characterized by motor symptoms, including tremor at rest, rigidity and impaired movement, as well as significant non-motor symptoms, including cognitive impairment and mood disorders. It is the second most common neurodegenerative disease after Alzheimer’s disease,2 and the prevalence of PD is increasing as the world’s population ages.

OFF episodes are the re-emergence or worsening of PD symptoms otherwise controlled with oral levodopa/carbidopa. These episodes may disrupt a person’s ability to perform everyday activities, can cause anxiety and may be burdensome for patients, family and care partners. OFF episodes are experienced by nearly 60 percent of people with PD within the first four to six years of diagnosis, and may worsen in frequency and severity over the course of the illness.
