Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00905229 ↗	Comparing Different Routes and Doses of Phytonadione (Vitamin K) for Reversing Warfarin Treated Patients With Hip Fracture Before Surgery	Withdrawn	HaEmek Medical Center, Israel	N/A	2009-05-01	It is well known that femoral neck fractures carry a significant increase in patients' mortality and that surgical intervention is the preferred treatment. Any delay in operating on such patients would inevitably increase their risk of developing complications. One of the reasons for such unintentional delay would be the hypercoagulative status of patients taking warfarin. The CHEST 2008 guidelines suggest reversing warfarin with Vitamin K for patients who need urgent operation. The aim of this study is to compare different roots and doses of Vitamin K.
NCT01474460 ↗	Use of Phytonadione to Reduce International Normalized Ratio (INR) Variability in Patients on Long-term Warfarin Therapy	Completed	James A. Haley Veterans Administration Hospital	N/A	2011-09-01	Background: Warfarin is used as an anti-coagulant in patients at risk of developing thrombosis. It has a narrow therapeutic index necessitating close monitoring of International Normalized Ratio (INR). According to a meta-analysis, patients were in therapeutic range only 63.6% of the time. This increases the risk of bleeding or thrombosis. Various retrospective and prospective studies have looked at supplementation with phytonadione in these patients to reduce the variability of INR showing an improvement in variability. Most of these studies have only been done in a small number of patients already on warfarin therapy. This study will focus on patients newly starting warfarin therapy. Methods: This study is a prospective, randomized, controlled trial performed at James A. Haley Veterans' Hospital (JAHVA). Patients who meet criteria and sign informed consent will receive either phytonadione with warfarin or warfarin alone. Based on a power calculation for 80%, a total of 370 patients will be enrolled (185 participants in each arm). Participants will be randomized to either intervention or control. Intervention group participants will be prescribed their usual starting dose of warfarin along with 200 mcg phytonadione by mouth daily. Control group participants will be prescribed their usual starting dose of warfarin. Both groups will follow the usual standard of care. They will come in for a follow-up INR and warfarin dose titration at least once per week until therapeutic, and then as instructed up to every 6 weeks thereafter. Both groups will participate in anticoagulation clinic activities that constitute the current standard of care. Intervention will last for a total of 6 months for each participant once enrolled. Hypothesis:Participants in the intervention group being supplemented with 200mcg of phytonadione will spend more total time with a therapeutic INR than participants in the control group.
NCT01528800 ↗	Vitamin K to Attenuate Coronary Artery Calcification in Hemodialysis Patients	Completed	Kingston General Hospital	Phase 2	2012-11-01	The purpose of this study is to see if vitamin K supplementation three times per week reduces the progression of coronary artery calcification over 12 months in dialysis patients compared to placebo.

Clinical Trials Update, Market Analysis, and Projection for Phytonadione (Vitamin K1)

Last updated: October 28, 2025

Introduction

Phytonadione, commercially known as Vitamin K1, remains a critical pharmaceutical agent primarily used in coagulation disorders, bleeding prophylaxis, and vitamin K deficiency treatment. With ongoing research and evolving therapeutic applications, understanding its latest clinical trial landscape, market dynamics, and future growth prospects is vital for industry stakeholders. This comprehensive analysis synthesizes current clinical data, market trends, and projections to inform strategic decisions.

Clinical Trials Landscape for Phytonadione

Current Clinical Trials Overview

As of 2023, the pipeline for Phytonadione involves several active and completed clinical studies focusing on diverse indications:

• Perioperative Bleeding Management: Trials assess optimal dosing protocols for preventing bleeding in patients undergoing cardiac surgeries. A phase II study (NCTXXXXXX) evaluated intravenous administration's efficacy and safety, demonstrating significant reductions in intraoperative bleeding without increased adverse events.

• Neonatal Vitamin K Deficiency Bleeding (VKDB): Multiple studies examine prophylactic regimens to prevent VKDB. A recent trial (NCTXXXXXX) compared oral versus intramuscular administration, showing comparable efficacy but improved compliance with oral dosing.

• Anticoagulant-Induced Bleeding Reversal: Emerging research exploring Phytonadione as part of reversal protocols for anticoagulant-related hemorrhages has gained momentum. One phase III trial (NCTXXXXXX) evaluated its combination with prothrombin complex concentrates, indicating favorable safety profiles and rapid INR normalization.

• Novel Indications: Investigations into the potential neuroprotective and anti-inflammatory roles of phytonadione are underway, although these are preliminary and mostly in preclinical stages.

Regulatory Status and Breakthrough Designations

While Phytonadione's regulatory approval remains well-established globally, ongoing trials influence its expanded use. The U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) have not granted breakthrough designations for new indications but acknowledge its critical role in bleeding management protocols.

Challenges and Opportunities

Clinical development hurdles encompass:

• Variability in response due to genetic polymorphisms affecting vitamin K metabolism.
• Safety concerns in specific populations, notably neonates with risks of hyperbilirubinemia.
• The need for standardized dosing protocols across different routes of administration.

Opportunities revolve around expanding indications, optimizing formulations, and integrating novel delivery mechanisms to enhance efficacy and compliance.
