Published Studies Related to Theo-24 (Theophylline)

The protective effect of theophyline in cisplatin nephrotoxicity. [2014]
Cisplatin is a potent and a major anti-neoplastic drug in the treatment of a broad spectrum of malignancies. However, its clinical use is limited by renal tubular dysfunction that occurs in a significant percent of patients...

Beneficial effects of theophylline infusions in surgical patients with intra-abdominal hypertension. [2011.08]
BACKGROUND: Intra-abdominal hypertension (IAH) can cause high mortality. Recently, we found that IAH was associated with increased serum levels of adenosine and interleukin 10. Our present "hypothesis-generated study" was based on the above mentioned results... CONCLUSIONS: Adenosine receptor antagonism with T following IAH diagnosis resulted in markedly reduced mortality in patients with moderated IAH (<20 mmHg). Theophylline-associated mortality reduction may be related to improved renal perfusion and improved MAP, presumably caused by adenosine receptor blockade. Because this study was not a randomized controlled study, these compelling observations require further multicentric clinical confirmation.

Study investigating pharmacokinetic interaction between theophylline and roflumilast in healthy adults. [2011.07]
OBJECTIVE: To investigate whether a pharmacokinetic drug-drug interaction exists between theophylline (THEO), a CYP1A2 substrate with a narrow therapeutic index, and the concomitant substrate roflumilast (ROF), a novel selective PDE4 inhibitor partially metabolized by CYP1A2... CONCLUSIONS: Neither ROF nor its main metabolite had any impact on the metabolism of the concomitant CYP1A2 substrate THEO in humans. Though co-administration of THEO resulted in a minor increase (28%) in total ROF exposure, no safety or tolerability concerns and no altered total PDE4 inhibition of both ROF and R-NO, were observed.

Clinical Trials Related to Theo-24 (Theophylline)

Neo-Adjuvant Therapy and the Effect on Synchronous Metastatic Growth [Recruiting]
Study Hypothesis

• As well as in animal models as in patients with colorectal cancer resection of the primary tumor resulted in increase in vascular density, metabolism and secondary tumor growth of the distant metastases. These data strongly suggest an inhibitory effect of the primary tumor on the outgrowth of its metastases.

In this study we investigate whether pre-operative treatment with the anti-angiogenic agent bevacizumab and/or chemotherapy before resection of the primary colorectal tumor shifts the balance between angiogenic and anti-angiogenic factors in favor of the anti-angiogenic factors and results in reduced growth of the liver metastases.

Eligibility

- Histological proven colorectal cancer without signs of bowel obstruction or bleeding

- Synchronous liver metastases

- WHO performance status 0-1

Treatment

- Arm A: immediate surgery of the primary colorectal tumor, no neoadjuvant therapy

- Arm B: neoadjuvant treatment with bevacizumab during 7 weeks prior to surgery of the

colorectal primary

- Arm C: neoadjuvant treatment with CAPOX during 7 weeks prior to surgery of the

colorectal primary

- Arm D: neoadjuvant treatment with bevacizumab and CAPOX during 7 weeks prior to surgery

of the colorectal primary

Primary endpoint Difference in response of liver metastases to resection of the primary tumor between the experimental groups and the control group, as determined by histopathological scoring of vascular density, apoptotic and mitotic index and by measurement of the metabolic activity of liver metastases by FDG-PET and SUV measurements.

Secondary endpoints Toxicity of neo-adjuvant treatment Complications of surgery

A Phase I Dose Escalation Study of Erlotinib in Combination With Theophylline [Not yet recruiting]
This study is to determine the use of theophylline in patients with NSCLC and advanced solid malignancies and whether treatment with theophylline will help lower or diminish the side effect of diarrhea in patients taking erlotinib. Patients will be enrolled in one of two parts of the study to verify the lowest dose of theophylline that is effective and the highest dose of erlotinib that can be tolerated with theophylline. If this study shows that theophylline is able to inhibit erlotinib induced diarrhea, it will help demonstrate that patients using the tyrosine kinase inhibitor (TKIs), erlotinib, can use it effectively at higher doses without experiencing severe diarrhea.

Optical Detection of Peripheral Nerve Bundles During Surgery [Recruiting]
Investigation of application possibilities of optical spectroscopy within the field of surgical resection procedures to spare nerve tissue. Optical spectroscopy enables the possibility to specifically differentiate between different (human) tissues. The hypothesis is that incorporation of this technique into existing medical devices (e. g. medical blade) would enlarge the accuracy and reliability of these devices. Sparing of nerve bundles during surgery can lead to decreased postoperative morbidity rates.

Evaluation of Metabolic Activity of Liver Metastases by FDG-PET Scanning [Recruiting]
The purpose of this study is to evaluate the effect of primary tumor resection on the metabolic activity of metastases in patients with a colorectal primary tumor and synchronous liver metastases by positron emission tomography (PET) with 2-deoxy-2-fluoro[18F]-D-glucose (FDG-PET) scanning.

Legtest Multi Centre Testing of the Lively Legs Program for Promoting Compliance in Leg Ulcer Patients [Recruiting]
Leg ulcers are often chronic or recurring complications of peripheral circulation disorders. Patients' lifestyles are known to influence leg ulcer occurrence and circulation disorders in general. Especially exercise and compliance with compression therapy are key elements in the course of leg ulcer healing and recurrence. Yet many patients demonstrate sedentary lifestyles and non-compliance and current practice offers no systematic approach in the promotion of compliance and physical activity in these patients.

The purpose of the study is testing 'Lively Legs' a compliance promotion program for patients with leg ulcers. The study tests the program on effects regarding:

- compliance with compression therapy and exercise levels

- time to leg ulcer recurrence

- cost effectiveness from a social perspective.
