NCT00311987 ↗	Study of 3,5-Diiodothyropropionic Acid (DITPA) in Hypercholesterolemic Patients	Terminated	Johns Hopkins University	Phase 1/Phase 2	2006-04-01	The natural thyroid hormones, thyroxine (T4) and triiodothyronine (T3), are known to have a cholesterol-lowering effect. Their pharmacologic use for this purpose is limited, however, by their actions on other organs, including the heart, bone, and brain, where there can be side effects of excessive thyroid hormone action. 3,5-diiodothyropropionic acid (DITPA) is a thyroid hormone analog with relative selectivity for a form of the thyroid hormone receptor expressed in the liver, where it regulates several aspects of lipid metabolism, including the clearance of low-density lipoprotein (LDL) cholesterol. This study is designed to determine whether DITPA is safe and effective in achieving LDL cholesterol levels that are consistent with the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines in patients who have not achieved those levels on conventional therapy, due to drug-resistant disease, drug intolerance, or both. This is a single-center, randomized, double-blind, placebo-controlled study. Following a 4-week Pre-Randomization Phase with dietary counseling and a 2-week placebo run-in, eligible patients will be randomized (1:1:1) to receive DITPA (90 mg/day, 180 mg/day), or placebo for a total treatment duration of 12 weeks. Sixty (60) patients will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio (i.e., 20 patients per treatment group): - DITPA at 90 mg/day (45 mg twice a day [BID] taken orally) - DITPA at 180 mg/day (90 mg BID taken orally) - Placebo (BID taken orally) Those patients randomized to receive DITPA at 90 mg/day will receive 45 mg/day for the first 2 weeks, followed by 90 mg/day for 10 weeks. Those patients randomized to receive DITPA at 180 mg/day will receive 45 mg/day for the first 2 weeks, followed by 90 mg/day for the next 2 weeks, and then 180 mg/day for 8 weeks.

Clinical Trials Update, Market Analysis, and Projection for Warfarin Potassium

Last updated: October 28, 2025

Introduction

Warfarin Potassium, a long-established anticoagulant, plays a pivotal role in preventing thromboembolic events such as stroke, deep vein thrombosis (DVT), and pulmonary embolism (PE). Its widespread clinical utilization since the mid-20th century and its status as a generic drug have historically made it a staple in anticoagulation therapy. However, recent developments in clinical trials, evolving market dynamics, and emerging therapeutic alternatives have significantly influenced Warfarin’s landscape. This article synthesizes current updates on clinical trials, analyzes market trends, and projects future market trajectories for Warfarin Potassium.

Clinical Trials Landscape and Recent Updates

Ongoing and Recent Clinical Trials

Warfarin’s clinical evaluation primarily focuses on optimizing its efficacy and safety profile amid the advent of novel oral anticoagulants (NOACs). However, recent trials are exploring its utility in specialized populations, combination therapies, and dose management strategies:

• Genetic-guided dosing: Several ongoing studies are scrutinizing pharmacogenetic approaches to personalize Warfarin dosing, aiming to reduce adverse events. The COAG trial (Clarification of Optimal Anticoagulation in the Genetically Targeted Population) compared genotype-guided dosing to standard care, with mixed results but indicating potential benefits in specific subgroups [1].

• Safety and adverse event management: Trials such as the PERIO trial investigate bleeding risk mitigation strategies, including co-administered agents and advanced monitoring techniques.
