Monotherapy with infusion therapies – useful or not?

Review

Author: Johansson, Anders ; Péter, Klivényi ; Milanov, Ivan ; Odin, Per ; Rožanković, Petra Bago

Infusion pump-based therapies are an effective treatment option for patients with advanced Parkinson´s disease. Achieving monotherapy with infusion-based therapies could simplify the treatment regimen, provide better medication adherence, reduce adverse events and drug interactions. This review presents the literature data on the efficacy, safety, and achievability of monotherapy with all available infusion-based therapies, including apomorphine, levodopa-carbidopa-intestinal gel (LCIG), levodopa-entacapone-carbidopa intestinal gel (LECIG), and foslevodopa-foscarbidopa (LDp/CDp). In summary, monotherapy is achievable and effective in most patients on intestinal levodopa infusion therapy and in some patients on apomorphine infusion. There is a need for further investigation of monotherapy compared to polytherapy, especially in new pump treatment options (LECIG and LDp/CDp). Future research should reveal which patients on infusion-based therapies could benefit from monotherapy, including identification of potential baseline predictors of achieving monotherapy in patients treated with specific infusion-based therapies.

The Catechol O-Methyltransferase Inhibitor Entacapone in the Treatment of Parkinson’s Disease: Personal Reflections on a First-in-Class Drug Development Programme 40 Years On

Review

Author: Hanttu, Anna ; Männistö, Pekka T ; Reinikainen, Kari J ; Pollesello, Piero ; Keränen, Tapani

In the 1980s, Orion Pharma, then a mid-ranking Nordic area pharmaceutical company, established a drug development programme on the inhibition of catechol O-methyltransferase (COMT). This enzyme, which plays an important role in the inactivation of catecholamine neurotransmitters and drugs with a catechol structure, thus came under consideration as a target in the innovative translational and clinical programme we describe in this historical review. The starting point was the conjecture that a peripherally acting COMT inhibitor might improve entry of levodopa into the brain. This had potentially significant implications for the medical treatment of Parkinson's disease (PD). The rationale was that more efficient delivery of levodopa to the brain might allow the high therapeutic doses of levodopa to be reduced and the dose interval to be extended. Elucidation of structure-activity relations paved the way for the discovery and development of entacapone, a 5-nitrocatechol that was a potent and highly specific inhibitor of COMT. Experience in phase III clinical trials established that entacapone, used as an adjunct to regular or controlled-release levodopa preparations (also including a peripherally acting dopa-decarboxylase inhibitor), increased ON-time and reduced OFF-time and improved clinical condition in patients with PD experiencing wearing-off, often with a reduced daily levodopa dose. Several of these studies also identified that entacapone improved patients' quality of life and was cost-effective. Subsequently, entacapone has been amalgamated into a triple-combination preparation (Stalevo®) with levodopa and carbidopa to create a flexible and convenient drug therapy for patients with PD who have end-of-dose motor fluctuations not stabilised on levodopa/dopa-decarboxylase inhibitor treatment. This review offers a historical perspective on a successful programme of drug development by researchers who played central roles in the progress from exploratory hypothesis to registered pharmaceutical product.

Real-world considerations regarding the use of the combination of levodopa, carbidopa, and entacapone (Stalevo^® ) in Parkinson's disease.

Review

Author: Reichmann, Heinz

An important aim in long-term levodopa therapy is to prolong the duration of symptomatic efficacy of each dose without increasing peak plasma concentrations above the threshold for the emergence of dyskinesias. One strategy is to enhance levodopa delivery to the brain by co-administering it with inhibitors of peripheral dopa-decarboxylase and catechol-O-methyltransferase (COMT). Levodopa, carbidopa and entacapone (LCE), available in a range of fixed-dose combinations as the branded formulation Stalevo^® (Orion Pharma), has been developed to address this requirement and has been in general use for 20 years, having first been evaluated in randomized controlled trials. Experience with LCE has established that improved levodopa pharmacokinetics achieved with dual-enzyme inhibition are translated into improved clinical efficacy, including the possibility of reducing total levodopa dosage with no loss of therapeutic effect. The ease and tolerability of switching to LCE has been affirmed in the SIMCOM trial and by personal experience detailed in this review. Some 300,000 patient-years of safety data are available for LCE, including trial data for up to 5 years. Most adverse effects associated with LCE are attributable to the levodopa component rather than the enzyme inhibitors. The hepatotoxicity observed with the class comparator tolcapone has not been observed with entacapone, the COMT inhibitor in LCE, and there is no formal requirement to monitor liver function during LCE therapy. Other common side effects include diarrhoea, which is one of the more prominent non-dopaminergic adverse events, and urine discolouration, which is harmless but about which patients may require reassurance.

Stada reports rosy earnings as CEO tempers expectations around possible sale, IPO

“Together with our 11,500 employees, my focus is on keeping Stada on a record-breaking trajectory in the second half of the year and growing faster than our competitors,” Stada Arzneimittel’s CEO, Peter Goldschmidt, said in a statement Wednesday. As Stada Arzneimittel’s private equity owners continue to weigh their options around a potential sale or public offering, the German drugmaker gave a good indication Wednesday of exactly what it can bring to the table.Over the first six months of the year, Stada generated sales of 2.02 billion euros ($2.2 billion), growing revenues 9% compared with the same period in 2023, the company said in a release. For the same period that ended June 30, Stada grew earnings before interest, taxes, depreciation, and amortization by 11% to 465.3 million euros ($515 million).All three of Stada’s business segments—consumer healthcare, generics and specialty pharma—contributed to the revenue growth, with specialty pharma delivering the biggest year-over-year change. The company also said it enjoyed a boon from its “rapidly growing” biosimilar offerings and from the launches of differentiated neurology and nephrology products.Notably, the question of whether Stada will eventually be sold—a prospect that’s been making headlines since last August— “will be decided exclusively by our owners,” the company’s CEO, Peter Goldschmidt, said in an emailed statement.He added that there is “no update” on Stada’s sales plans at this time and explained that the drugmaker’s owners, Cinven and Bain Capital, are “examining various options, including an IPO.”“Together with our 11,500 employees, my focus is on keeping Stada on a record-breaking trajectory in the second half of the year and growing faster than our competitors,” Goldschmidt added. Taking a closer look at the numbers, Stada’s specialty pharma arm grew sales 14% to 417.3 million euros ($464 million) during the first half of 2024. Stada credited the specialty pharma growth to its swelling biosimilar portfolio plus brands like the Parkinson’s disease therapy Lecigon and the orphan medicine Kinpeygo in a rare kidney disease.Elsewhere, generics sales jumped 12% to 838.2 million euros ($932 million), driven in part by the launch of the complex copycats for deep vein thrombosis, rivaroxaban and dabigatran, across multiple European countries, Stada said. Rivaroxaban is the generic of Johnson & Johnson’s Xarelto, while dabigatran is sold by Boehringer Ingelheim under the brand name Pradaxa.In its release, Stada called its generics business a “consistent and sustainable growth driver” for the company, noting that it expects to benefit from a generics launch pipeline that already covers some “80% of original medicines that will lose exclusivity over the next few years.”As for the last pillar of Stada’s business, the company’s consumer healthcare segment saw revenues climb 3% to 768.3 million euros ($854 million).Last August, Bloomberg reported that Stada’s owners, Cinven and Bain, were weighing options for the company, including a possible sale. At the time, sources close to the talks told the news service that the sale could value Stada at 10 billion euros or more. Goldschmidt last year told the German Press Agency that Cinven and Bain were conducting “initial exploratory talks” around the potential fate of the company, though he stressed that the investors were under “no pressure to sell.”More recently, Stada in April kicked off talks with potential buyers in a sale that could value the company at around 8 billion euros, Bloomberg reported at the time, citing people with knowledge of the discussions. The news outlet’s sources added that Stada’s private equity owners were also weighing a potential initial public offering.Bain and Cinven agreed to buy Stada for 5.3 billion euros in 2017. The deal gave the private equity firms control of what was one of the last independent generic drug makers in Europe.
