Trial Type	Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
New Indication	NCT05387187 ↗	Evaluate the Effect and Safety of Pu Yang Wan Wu Tang and Western Medicine on Chronic Kidney Disease	Not yet recruiting	Taipei Medical University Hospital	Phase 2/Phase 3	2022-06-01	The indication of Pu Yang Wan Wu Tang is stroke sequelae, such as half body paralysis, aphasia and muscle weakness. Pu Yang Wan Wu Tang is proved to have the effect of protecting nerve and blood vessel, anti-inflammation, anti-coagulation, dilating peripheral vessel, promot-ing micro circulation, improving hemodynamics, and activating central nerve system. Huangqi could attenuate podocyte injury by regulating the expression and distribu-tion of nephrin and podocin. Huangqi and Danggui are associated with fewer infiltra-tion of macrophages and limitation of renal intrinsic cell activation, which may lead to earlier and persistent reduction of proteinuria. This research will use the compound Chinese medicine, Pu Yang Wan Wu Tang. Those treatments combined Western medicine to assess the efficacy and drug safety on the CKD cases. Series of blood and urine were collected regularly during study to prove the role of Chinese medicine in the treatment of CKD, and to assess their drug safety. The final goal of the plan is to establish the new indication of Pu Yang Wan Wu Tang and enhance the interaction and cooperation between Chinese and Western medicine.
OTC	NCT06016452 ↗	A Study of Chlorophyllin for the Management of Brain Radio-necrosis in Patients With Diffuse Glioma	Recruiting	Bhabha Atomic Research Centre (BARC)	Phase 2	2023-11-13	Diffuse gliomas are common tumors involving the brain. They are usually treated by surgery followed by radiation and chemotherapy. Radiotherapy is used for the treatment of brain tumors which causes damage to the tumor cells. However, radiotherapy can also affect the surrounding healthy cells in the brain, causing inflammation and swelling in the region, which is known as radio necrosis (RN). This is considered a late side effect of radiation and is seen in 10-25% of patients treated with radiation for brain tumors. Sometimes, radionecrosis can be detected on routine imaging during follow-up without new symptoms (asymptomaticRN). At the same time, in some patients, it can give rise to new symptoms like headaches, weakness, seizures,etc (symptomatic RN). The standard treatment of RN includes steroid medicines called dexamethasone, which is helpful in a proportion of patients. This is a prospective phase 2 study. This study is being conducted to investigate the ability of the drug Chlorophyllin in the treatment of radionecrosis. Chlorophyllin is a water-soluble compound obtained from the green plant pigment called chlorophyll. It has been shown to have anti-cancer, anti-bacterial, anti-viral, anti-inflammatory, and antioxidant properties. It is also used as an oral formulation and is an over-the-counter drug in various countries, and also as a food colouring agent. This is the first time chlorophyllin will be used in the setting of brain radionecrosis. Our primary aim of the study is to assess whether CHL will improve the clinical-radiological response rates. This study will be conducted on a population of 118 patients for a duration of 3 months. The total study duration is 2 years. The study is funded by Bhabha Atomic Research Centre (BARC).

Pentoxifylline decreases tumor necrosis factor (TNF), and therefore should decrease such TNF-intensified events as cachexia, enhanced HIV expression, and inhibition of zidovudine (AZT) activity.
NCT00001437 ↗	Trial of Pentoxifylline in Patients With Functional Disability Caused by Radiation-Induced Advanced Regional Fibrosis	Completed	National Cancer Institute (NCI)	Phase 2	1995-06-01	After initial assessment of their condition by specified clinical and laboratory parameters, each of the patients will be treated for 8 weeks at the standard pentoxifylline dose (400 mg po TID). Objective and subjective response parameters will be re-assessed at the end of the treatment and 8 weeks later for possible decay of response.
NCT00001877 ↗	Treatment of Pulmonary Sarcoidosis With Pentoxifylline	Completed	National Heart, Lung, and Blood Institute (NHLBI)	Phase 2	1999-02-01	Sarcoidosis is a disease most commonly affecting the lungs, but it can also involve lymph nodes, skin, liver, spleen, eyes, bones, and glands. The cause of the disease is unknown. When it occurs it can produce an inflammatory reaction leading to irreversible organ damage and disability. In sarcoidosis granulomas can form in various organs (primarily lung) which can lead to its dysfunction. Granuloma is formed by clusters of inflammatory cells. The formation of these granulomas is influenced by the release of a substance called TNF-alpha (tumor necrosis factor alpha) which is found in some white blood cells. A drug known as pentoxifylline (POF) is known to markedly reduce the release of TNF-alpha. The standard medical treatment for sarcoidosis is steroid therapy. However, steroid therapy is associated with significant side effects and often must be stopped. Unfortunately, some of these patients can relapse when the steroid therapy is discontinued. Because of this, researchers are interested in finding alternative therapies for the treatment of sarcoidosis. This study will evaluate the effectiveness of giving POF to patients with sarcoidosis currently taking steroids. Researchers will compare the results between patients taking steroids with pentoxifylline and those patients taking steroids alone.
NCT00002091 ↗	An Evaluation of Pentoxifylline in HIV-Positive Persons With Symptomatic HIV Infection and a Karnofsky Score > 40 Percent and < 100 Percent	Completed	Community Research Initiative of New England	N/A	1969-12-31	PRIMARY: To determine whether pentoxifylline changes the self-reported measures of quality of life status, using measures of scores from double-blinded drug withdrawal and drug restart periods. SECONDARY: To measure the changes in monthly CD4 counts, fasting serum triglyceride levels, and weight; to assess the safety of pentoxifylline in HIV-infected persons.
NCT00003407 ↗	Amifostine and High-Dose Combination Chemotherapy in Treating Patients With Acute Myeloid Leukemia or Chronic Myelogenous Leukemia	Unknown status	National Cancer Institute (NCI)	Phase 2	1998-04-01	RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Chemoprotective drugs, such as amifostine, may protect normal cells from the side effects of chemotherapy. PURPOSE: Phase II trial to study the effectiveness of amifostine and high-dose combination chemotherapy in treating patients with acute myeloid leukemia or chronic myelogenous leukemia.

Pentoxifylline: Clinical Trials, Market Analysis, and Projections

Introduction

Pentoxifylline, a xanthine derivative, has been widely used in the management of peripheral vascular disease and other conditions due to its anti-inflammatory, anti-fibrotic, and hemorheological properties. This article provides an update on the clinical trials, market analysis, and projections for pentoxifylline.

Clinical Trials and Efficacy

Peripheral Vascular Disease

Pentoxifylline is primarily used to treat symptoms of intermittent claudication due to peripheral vascular disease. It improves blood flow by reducing viscosity and enhancing red blood cell flexibility, thereby alleviating symptoms such as pain and cramping in the legs[1].

Venous Ulcers

Clinical studies, including a Cochrane review, have shown that pentoxifylline is effective in treating venous ulcers, both with and without compression therapy, compared to placebo or no treatment[1].

Severe Alcoholic Hepatitis

Pentoxifylline has been found to be beneficial in treating severe alcoholic hepatitis, particularly when contraindications to corticosteroids exist. It acts as a tumor necrosis factor-α (TNF-α) inhibitor, reducing the risk of fatal hepatorenal syndrome[1].

COVID-19 and Cytokine Storm Syndrome

A recent randomized clinical trial investigated the effects of pentoxifylline on hospitalized COVID-19 patients with cytokine storm syndrome. The study found that pentoxifylline reduced inflammatory markers such as IL-6 and improved clinical outcomes, although the differences in hospital stay and mortality were not statistically significant[4].

Other Indications

Pentoxifylline has also shown promise in reducing ischemia-reperfusion injury, drug-induced nephrotoxicity, and improving outcomes in patients undergoing cardiopulmonary bypass and those with type-2 diabetic nephropathy[1].

Mechanism of Action

Pentoxifylline's therapeutic effects are attributed to its ability to:

• Inhibit phosphodiesterase, which improves blood flow.
