OTC	NCT00125281 ↗	SAMe to Treat Biliary Cirrhosis Symptoms	Terminated	National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)	Phase 2	2005-07-25	This study will examine the effect of S-adenosyl methionine (SAMe) on itching and fatigue in patients with primary biliary cirrhosis, a disease of the small bile ducts in the liver. Ursodiol, the only currently available treatment for biliary cirrhosis, does not cure the disease, and many people continue to have symptoms or liver test abnormalities despite treatment. SAMe is a naturally occurring substance found in most cells of the body. The highest levels of the substance are produced by the liver, where it helps to rid the body of toxins and breakdown products of metabolism. Studies in Europe suggest that SAMe may help to: 1) decrease the fatigue and itching that are common in persons with liver problems, and 2) decrease levels of liver enzymes in the blood, suggesting that it may decrease the amount of liver injury. Patients 21 years of age or older with primary biliary cirrhosis who are taking ursodiol and have symptoms of itching or fatigue may be eligible for this study. Candidates are screened with a medical history, physical examination, review of medical records, routine blood tests, and a symptoms rating scale. Participants stop all medications for itching 4 weeks before starting the study, but continue to take ursodiol during the 42-week trial. On entering the study, patients are assigned to take either SAMe or placebo tablets twice a day for 12 weeks. While taking the medications, they are followed in the clinic every 2 weeks for the first month and then every 4 weeks to fill out symptoms questionnaires and have a short medical evaluation and blood tests. At the end of 12 weeks, treatment is interrupted for a 2-week "wash-out" period, after which patients begin a 12-week crossover treatment; that is, patients who were taking SAMe are switched to placebo, and those who were taking placebo are switched to SAMe. After completing the second 12-week treatment course, patients come to the clinic at 4, 8, and 12 weeks to fill out symptoms questionnaires and have a medical evaluation and blood tests. At the last visit, patients are told which type of tablet they received during the two courses of treatment. SAMe is available without prescription in many forms as an over-the-counter medication.
New Formulation	NCT00490932 ↗	New Hypo-Osmolar ORS (Recommended by WHO) for Routine Use in the Diarrhea Management- Surveillance Study for Adverse Effects	Completed	Society for Applied Studies	Phase 4	2005-03-01	For more than 25 years WHO and UNICEF have recommended a single formulation of glucose-based Oral Rehydration Salts (ORS) to prevent or treat dehydration from diarrhoea irrespective of the cause or age group affected. This product has proven effective and contributed substantially to the dramatic global reduction in mortality from diarrhoeal disease during the period. Based on more than two decades of research and recommendations by an expert group, WHO and UNICEF reviewed the effectiveness of a new ORS formula with reduced concentration of glucose and salts. Because of the improved effectiveness of this new ORS solution WHO and UNICEF recommended that countries use and manufacture this new formulation in place of the old one. While recommending this new ORS the experts also recommended that further monitoring is desirable to better assess the risk, if any of symptomatic hyponatraemia (low blood level of sodium salt). This is a surveillance study to evaluate adverse effect of routinely using the new ORS in a hospital admitting over 20,000 patients with diarrhea of all ages including cholera. If the new ORS is found safe, it will provide added confidence in its global use.
OTC	NCT01451918 ↗	Regulation of Intestinal and Hepatic Lipoprotein Secretion by Resveratrol	Completed	Canadian Institutes of Health Research (CIHR)	Phase 2	2011-10-01	Resveratrol, an ingredient of red wine and available in Canada in highly purified form as an over-the-counter health supplement, has been shown to have a number of health benefits. Data from in vitro and animal studies suggest that it has beneficial effects on insulin sensitivity and lipid lowering. The investigators are not aware, however, of any mechanistic studies that have examined the effect of highly purified resveratrol in vivo on lipoprotein metabolism in humans. Given the potential therapeutic benefit of resveratrol in correcting the metabolic abnormalities of insulin resistant individuals the investigators plan to examine the effects of resveratrol on intestinal and hepatic lipoprotein production in humans.

OTC	NCT01755702 ↗	Paracetamol With Caffeine to Treat Episodic Tension Type Headache	Terminated	GlaxoSmithKline	Phase 2/Phase 3	2009-07-01	This study will compare a fast-absorbing paracetamol plus caffeine formula with placebo and an over-the-counter dose of paracetamol and ibuprofen to treat episodic tension headache.
New Formulation	NCT01948583 ↗	Humectant Activity of a New Formulation of Gynomunal® Vaginalgel	Completed	Derming SRL	Phase 4	2013-05-01	Aim of the study is to evaluate the humectant activity and the local tolerability of a new formulation of Gynomunal® vaginalgel in menopausal women (menopause since at least 2 years) with referred vaginal dryness
New Dosage	NCT02103244 ↗	Validation of an Adjusted Dosing Algorithm of Carboplatin	Unknown status	Rijnstate Hospital	Phase 4	2014-09-01	An adjusted dosing algorithm for the dosing of the anticancer drug carboplatin has been developed, that accounts for high BMI, low serum creatinine values and maximal calculated renal function. The hypothesis is that this new dosing algorithm provides a more accurate and safe dose than dosing according to the old standard of care.

NCT00000981 ↗	The Safety and Effectiveness of FIAC in the Treatment of Cytomegalovirus (CMV) in Patients With AIDS	Completed	Oclassen Pharmaceuticals	Phase 2	1969-12-31	To find oral doses of FIAC (a pyrimidine nucleoside analog) that are effective in treating cytomegalovirus (CMV) viremia in HIV-infected immunocompromised patients; to determine tolerance and safety of FIAC in this patient population; and to determine pharmacokinetics following multiple doses of FIAC. (An example of another nucleoside analog effective against retroviruses such as HIV is zidovudine (AZT).) CMV infection is a medically significant opportunistic disease in patients with HIV-related infection. The purine nucleoside ganciclovir has been used to treat AIDS patients with CMV disease. Although ganciclovir is useful in treating CMV disease, such treatment is frequently complicated by hematologic (blood) toxicity. Also, treatment is difficult because it requires daily intravenous dosing. Test tube studies show that FIAC and its primary breakdown product FIAU are highly and specifically active against several viruses including CMV. A single-dose, pharmacokinetic (blood level) study showed that FIAC, when taken orally, is readily absorbed into the bloodstream, and most of it is converted to FIAU.

Clinical Trials Update, Market Analysis, and Projection for Vicks Formula 44

Last updated: July 16, 2025

Introduction

Vicks Formula 44, a staple over-the-counter cough suppressant from Procter & Gamble, has long dominated the respiratory relief market. First introduced in the 1940s, this dextromethorphan-based formulation continues to address cough symptoms amid evolving consumer demands and regulatory scrutiny. This analysis delves into the latest clinical trials, current market dynamics, and future projections, offering business professionals actionable insights into its performance and potential.

Clinical Trials Update

Recent developments in clinical trials for Vicks Formula 44 reflect a broader industry push toward enhanced efficacy and safety for cough remedies. In 2023, Procter & Gamble initiated a Phase IV post-marketing surveillance study, registered under NCT05876592 on ClinicalTrials.gov, to evaluate the drug's real-world effectiveness in managing acute coughs among adults aged 18-65. This trial, involving over 1,500 participants across the United States and Europe, focused on comparing Formula 44's outcomes against placebo controls, measuring metrics such as cough frequency reduction and quality-of-life improvements over a 14-day period.

Preliminary results, released in early 2024, indicate a 25% greater reduction in cough severity scores compared to placebos, with no significant adverse events reported beyond mild drowsiness—a common side effect of dextromethorphan. This builds on a 2021 study published in the Journal of Clinical Pharmacology (Volume 61, Issue 3), which examined Formula 44's interaction with other common medications, confirming minimal risks for polypharmacy patients.

Regulatory bodies like the FDA have not flagged any major concerns, but ongoing trials emphasize transparency. For instance, a 2024 extension study (NCT06234145) is exploring pediatric applications, testing lower doses in children aged 6-12 to address gaps in current labeling. Early data suggests efficacy comparable to adult formulations, potentially paving the way for expanded indications by 2026, pending FDA review.

These updates underscore Procter & Gamble's commitment to evidence-based improvements, especially as consumer preferences shift toward natural alternatives. However, Formula 44's active ingredient remains a synthetic staple, distinguishing it in a market increasingly dominated by herbal options.

Market Analysis

The global cough syrup market, valued at approximately $7.5 billion in 2023, positions Vicks Formula 44 as a key player with a 12% market share in the OTC segment, according to data from Statista's 2023 pharmaceutical report. Procter & Gamble leverages Formula 44's brand heritage to maintain dominance in North America and Europe, where it captured 15% of cough suppressant sales last year. Competitors like Robitussin (Haleon) and Mucinex (Reckitt Benckiser) challenge this lead, with Robitussin holding 18% share through aggressive pricing and broader formulations.

In the U.S., Formula 44 generated $450 million in retail sales in 2023, per NielsenIQ data, driven by seasonal demand during flu seasons. Its appeal lies in accessibility—available in major chains like Walmart and CVS—and a pricing strategy that keeps a 4-ounce bottle under $10, ensuring affordability amid inflation. Market segmentation reveals strong performance among middle-aged demographics (35-54 years), who prioritize fast-acting relief, as evidenced by a 2023 Kantar survey showing 68% user satisfaction for cough suppression.

Geographically, Asia-Pacific emerges as a growth hotspot, with Formula 44 expanding via e-commerce platforms like Alibaba, where sales surged 40% year-over-year in 2023. This contrasts with mature markets like the UK, where Brexit-related supply chain disruptions reduced availability, dropping market share from 14% in 2022 to 11% in 2023, based on Euromonitor International's analysis.

External factors, such as the post-COVID surge in respiratory illnesses, have boosted demand, with Formula 44 benefiting from Procter & Gamble's marketing campaigns emphasizing immune support. However, regulatory hurdles, including FDA warnings on dextromethorphan misuse in 2022, have prompted reformulations to include child-resistant packaging, potentially eroding 5% of sales in the youth segment.

Market Projection

Looking ahead, the cough syrup market is poised for 4.5% annual growth through 2030, reaching $9.8 billion, as projected by Grand View Research in their 2024 report. Vicks Formula 44 is expected to maintain or slightly expand its market share to 13% by 2028, fueled by innovation and digital outreach. Procter & Gamble's investment in R&D, totaling $200 million in 2024, targets sustainable formulations, such as a plant-based variant anticipated for 2026 launch, which could capture an additional 2% share in eco-conscious markets.

In North America, projections estimate Formula 44 sales to hit $550 million by 2027, driven by e-commerce growth and personalized health trends, per Forrester Research's 2024 digital health forecast. Europe may see modest gains at 3% annually, contingent on resolving supply issues, while Asia-Pacific could double its contribution, propelled by rising middle-class populations and urbanization.

Challenges include intensifying competition from generic brands, which offer 20-30% lower prices, potentially capping Formula 44's growth at 2% in price-sensitive regions. Regulatory shifts, such as potential EU restrictions on synthetic ingredients by 2025, as outlined in the European Medicines Agency's 2023 guidelines, might necessitate costly adaptations, reducing profit margins by 5-7%.

Overall, Formula 44's projection hinges on Procter & Gamble's agility in addressing these dynamics, with AI-driven demand forecasting tools expected to optimize inventory and boost efficiency by 15%, according to Deloitte's 2024 supply chain analysis.
