The purpose is to monitor clinical status, adverse events, laboratory investigations and to assess relative safety and tolerance of ondansetron formulations under fed conditions.
NCT01676844 ↗	Investigating a New Way of Giving Medicine to Newborn and Preterm Babies	Unknown status	University of Strathclyde	Phase 2	2013-02-01	There is a deficit in the number of 'age-appropriate' formulations available for the delivery of medicines to children. Liquid preparations are considered the 'gold standard' for delivering medicines to children however many of these are formulated using ingredients which can be toxic to children (e.g. preservatives, alcohols), particularly to neonatal babies (< 4 weeks old) who do not possess the metabolic processes and mature organ function of older children or adults. Rapidly dissolving oral thin films (OTFs) dissolve quickly in the saliva, releasing the active ingredient(s) without the need for chewing or water, making them ideally suited to patients who find it difficult to swallow other oral dosage forms such as tablets or capsules. The aim of this study is to demonstrate that OTFs can offer a safe and effective alternative for oral administration of phosphate supplements to neonatal infants for the treatment of hypophosphataemia and osteopenia of prematurity. It is hypothesised that this treatment will be equal to standard therapy using an oral solution. Babies born before 32 weeks gestational age are routinely supplemented with oral phosphate as soon as they have been established on oral feeds in order to prevent bone disorders such as osteopenia. Babies recruited to this study will be given phosphate supplementation as per NHS Greater Glasgow and Clyde guidelines. This single-centre cross-over study will take place in the intensive care and special care baby units at the Princess Royal Maternity in Glasgow. The investigators aim to recruit 20-30 babies and will use blood phosphate levels (obtained from routine sampling only) to evaluate treatment effect. Babies will be randomised to receive either OTFs or oral solution of potassium acid phosphate for 2 weeks followed by 2 weeks of the other therapy. The investigators hypothesise that OTF treatment will be equivalent to standard oral solution.
NCT02082678 ↗	Ondansetron for Bipolar Disorder and Alcohol Use Disorders	Completed	Stanley Medical Research Institute	Phase 4	2014-02-01	The purpose of the study is to determine if ondansetron, as an add-on therapy, is associated with reduced depressive symptoms and alcohol use in outpatients with bipolar disorder (BPD), cyclothymic disorder, schizoaffective disorder (bipolar type) and major depressive disorder (MDD) with mixed features. The investigators will also use blood samples to determine if the genotype for the serotonin transporter gene is associated with response to ondansetron.

Introduction

ZUPLENZ, a novel therapeutic agent developed for the treatment of chronic, fluid-associated neurological disorders, has garnered significant attention within the pharmaceutical industry. Launched amidst a landscape eager for more effective treatments for complex neurological conditions, ZUPLENZ combines innovative pharmacology with promising clinical trial data. This report provides a comprehensive update on its ongoing clinical trials, evaluates its market landscape, and offers projections grounded in current trends and data.

Clinical Trials Update

Phase I and II Trials

Initial Phase I studies for ZUPLENZ focused on establishing safety, dosage, and pharmacokinetics. Conducted across multiple centers in North America and Europe, these trials confirmed favorable safety profiles with minimal adverse effects. The pharmacodynamic assessments indicated robust central nervous system (CNS) penetration, a critical factor for efficacy in neurological indications.

Subsequent Phase II trials, completed recently, targeted a cohort of patients with refractory neurological fluid retention conditions, including idiopathic intracranial hypertension and certain forms of neurodegenerative diseases characterized by fluid dysregulation. The trials enrolled approximately 350 participants across 20 centers globally. Results demonstrated statistically significant improvement in symptom severity, as measured by standardized neurological scales, with a reduction in intracranial pressure and fluid accumulation noted within four weeks of treatment initiation.

Ongoing and Pending Trials

Currently, ZUPLENZ is advancing into Phase III. The pivotal trial, designated ZUPLENZ-300, aims to enroll over 600 patients across North America, Europe, and Asia. This randomized, double-blind, placebo-controlled study focuses on long-term safety and efficacy, with endpoints including neurological function, quality of life metrics, and biomarker validation.

Recruitment for ZUPLENZ-300 has reached 85% completion as of Q1 2023, with interim safety analyses indicating no significant adverse trends. The trial is on schedule with preliminary efficacy data expected by late Q3 2023. Regulatory filings for expedited review pathways, such as Breakthrough Therapy designation in the U.S., are in preparation based on initial positive signals.

Regulatory and Market Access Pathways

In parallel, the manufacturer has engaged with regulatory agencies, including the FDA and EMA, to facilitate adaptive pathways. The company submitted a rolling Biologics License Application (BLA) in Q2 2023 for accelerated review, citing promising clinical data and the unmet medical need.

Market Analysis

Market Landscape and Unmet Needs

The global neurological disorder market is projected to reach USD 290 billion by 2027, driven by aging populations and increasing prevalence of neurodegenerative conditions such as Alzheimer’s disease, Parkinson’s disease, and neuro-inflammatory disorders. Within this space, therapeutic options for conditions characterized by aberrant fluid accumulation remain limited, often symptomatic, with significant unmet medical needs.

ZUPLENZ addresses these gaps, notably in conditions where currently approved therapies are insufficient or carry high adverse event profiles. Conditions like idiopathic intracranial hypertension and certain neurodegenerative states have few targeted options, positioning ZUPLENZ to secure a significant niche.

Competitive Positioning

Major competitors include monoclonal antibodies (e.g., aducanumab), small molecules like acetazolamide, and other biologics targeting CNS fluid regulation. However, ZUPLENZ’s unique mechanism of action, which modulates specific cerebrospinal fluid pathways, offers a differentiated profile. Its favorable safety data and apparent efficacy advantages further distinguish it.

Market Penetration Potential

Assuming successful Phase III outcomes and regulatory approval, ZUPLENZ could rapidly penetrate markets with an initial focus on North America and Europe, where neurological disorder prevalence is high and reimbursement pathways are established. The global market expansion into Asia remains promising due to increasing healthcare infrastructure and the burden of neurological diseases.

Pricing and Reimbursement Outlook

Pricing strategies for ZUPLENZ are under development, with early estimates positioning it within the $10,000 - $20,000 annual treatment cost bracket, considering its targeted indication and superior safety profile. Reimbursement prospects are favorable, contingent upon demonstrating cost-effectiveness through health economic data, especially given the high societal costs associated with neurological disabilities.

Market Projections and Growth

Based on current clinical trajectory and unmet needs, market analysts project ZUPLENZ could achieve peak annual sales of USD 1.5 billion by 2028. Adoption rates depend heavily on regulatory outcomes, post-approval pricing strategies, and physician acceptance. Early-advantage positioning, including patent protections and collaborative healthcare strategies, will be critical.
