, long-term follow-up of a phase 3 study has shown. Besides the usual adverse effects with apomorphine, the sublingual film was associated with more oral adverse effects than seen with the injectable drug. However, it may have some advantages over subcutaneous apomorphine injections in terms of administration during off episodes.
The study was presented at the Movement Disorder Society 23rd International Congress of Parkinson’s Disease and Movement Disorders (Virtual) 2020.
For example, the new formulation is more convenient than carrying an injection. It comes in a small, tear-open packet that contains a medication strip patients place under their tongues.
“When a patient is in the off state, depending on how off they are, they could have a little difficulty opening the strip [packet], but anyone can open the strip for them,” said lead author Rajesh Pahwa, MD, professor of neurology and chief of the Parkinson and Movement Disorder Division at the University of Kansas Medical Center in Kansas City. “On the other hand with the subcutaneous, they have to give the injection themselves and a stranger or someone is not going to help them with that.”
Open-label safety and efficacy study
The aims of this open-label, 48-week follow-up were to add new patients to assess safety and tolerability over the long term and to see if continued benefit from a previous 12-week double-blind study was still present at 1 year for patients in the earlier study.
This multicenter study (NCT02542696) included “rollover” patients (n = 78 for safety; n = 70 for efficacy) from the previous phase 2/3 double-blind trial, as well as new patients with no prior exposure to apomorphine sublingual film (n = 347 for safety; n = 275 for efficacy).
New patients experienced one or more off episodes per day with a daily off time of 2 hours or more per day while on stable doses of levodopa/carbidopa. All had clinically meaningful responses to levodopa/carbidopa and were judged by the investigator to be Stage 1-3 by modified Hoehn and Yahr scale rating during ON periods.
Rollover patients completed the prior study and had no major changes in their anti-Parkinson’s medications since then. Mouth cankers or sores were exclusion criteria for either group. New subjects could not have received subcutaneous apomorphine within 7 days of a screening visit.
The demographics and baseline characteristics of the new and rollover groups were similar (approximately 64 years; 65%-71% male; 96% White; 8.3-9.6 years since diagnosis; 3.9 to 4.1 off episodes/day, and total mean daily levodopa dose of 1120 to 1478 mg).
Assessing only the group of new patients, the investigators reported that 80% had a Hoehn and Yahr score of 2 or 2.5 when in the ON state and a Movement Disorder Society–Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) Part III predose score of 41.8.
At the beginning of this study, patients in an off period received titrated doses of 10-35 mg of sublingual apomorphine in 5 mg increments during sequential office visits until they achieved a tolerable full ON within 45 minutes of a dose. They then entered a 48-week safety and efficacy phase, during which they self-administered the drug at home up to five times daily for off episodes with a minimum of 2 hours between doses. The investigators could adjust the doses for safety or lack of efficacy.
Two-thirds of new patients and three-quarters of rollovers received doses in the 10-20 mg range. The highest dose in the study of 35 mg was used by only 8%-9% of patients, but the highest approved and marketed dose is 30 mg.
Long-term benefits
Onset of efficacy was achieved by 15 minutes after dose for both new and rollover patients, and maximal efficacy occurred by 30 minutes. Results were very similar at 24, 36, and 48 weeks. The investigators did not perform statistical analyses.
Across study weeks 1, 12, 24, 36, and 48, between 77% and 92% of new patients and between 65% and 77% of rollover patients self-reported full ON within 30 minutes. “The long-term benefits are maintained over a year as far as the speed of onset and the duration,” Dr. Pahwa said.
Treatment-emergent adverse events occurred in about half of the new and the rollover patient groups in the titration phase and in 71%-81% of patients during the long-term safety phase. Nearly all were mild to moderate in severity.
A large number of participants withdrew from this long-term safety phase because of adverse events – 90 (33%) of new enrollees and 16 (23%) of rollover patients. Only 4% dropped out for lack of efficacy, all in the new enrollee group. Because the sublingual formulation is delivered under the tongue, patients in that group had more oral side effects, Dr. Pahwa said. Otherwise, “the side effects were very similar to the subcutaneous delivery.”
Treatment-emergent adverse events specific to sublingual apomorphine included oral mucosal erythema, lip or tongue swelling, and mouth ulceration (6% to 7% of patients each). Occurring less often were glossodynia, oral candidiasis, stomatitis, and tongue ulceration (2% each).
These were in addition to adverse events typically occurring with subcutaneous apomorphine, which are nausea, falls, dizziness, somnolence, dyskinesia, syncope, and yawning.
There are no head-to-head comparisons of sublingual versus subcutaneous delivery of apomorphine. But based on experience, Dr. Pahwa said, “With the subcutaneous, you have a slightly faster onset of action compared to the sublingual. However, sublingual has a slightly longer duration of benefit.”
He predicted that patients may prefer using an injection for a faster benefit or a sublingual for a slightly longer benefit.
More therapeutic options are welcome
Commenting on the study, Ray Dorsey, MD, professor of neurology at the University of Rochester (N.Y.), said that, for people with more advanced Parkinson’s disease “there’s usually a caregiver who’s injecting someone with an off period, as opposed to sublingual, which seems like a much easier way of administering a drug, especially for people with motor fluctuations.”
He noted that adverse events that led to premature discontinuation from the study “are concerning about the overall tolerability of the drug, which also will be determined in clinical practice, and will likely influence its overall utility.”
However, more therapeutic options are welcome because “the number of people with advanced Parkinson’s disease is going to grow and grow substantially,” he said. “So having therapies that help people with more advanced Parkinson’s disease ... many of whom don’t reach the clinic ... are going to be increasingly important.”
The study was supported by Sunovion. Dr. Pahwa and Dr. Dorsey reported conflicts of interest with numerous sources in industry.
