About this study

Official title: International Randomized, Controlled Phase 3 Trial of DB289 Versus Trimethoprim-sulfamethoxazole for the Treatment of Acute Pneumocystis Jiroveci Pneumonia (PCP) in Patients With HIV/AIDS

The purpose of this study is to demonstrate the non-inferiority of pafuramidine maleate (DB289)versus trimethoprim-sulfamethoxazole (TMP-SMX)for the treatment of mild to moderately severe Pneumocystis pneumonia (PCP).

Read the detailed description

The gold standard treatment for PCP is trimethoprim-sulfamethoxazole (TMP-SMX). This drug is highly effective; however, a significant number of patients are unable to complete a course of therapy due to adverse events, some of which can be life-threatening. In addition, mutations that confer resistance to sulfa-based drugs in other microorganisms are increasingly being reported in P. jiroveci. A potential role of these mutations in conferring clinical resistance to PCP and in breakthroughs to prophylaxis regimens based on sulfa drugs is being actively studied. Second and third line agents or combinations for PCP treatment are also limited in efficacy and/or by adverse events.

A new agent such as pafuramidine maleate (DB289), which has well documented activity against P. carinii in animal models, documented efficacy in a preliminary study trial in HIV-infected patients with PCP that were intolerant or resistant to TMP-SMX, was well tolerated in this trial and demonstrated a low toxicity profile in Phase 1 studies, would meet a significant medical need. Furthermore, pafuramidine maleate is active against other pathogens responsible for significant morbidity and mortality in patients with AIDS in the developing world, like different strains of Plasmodium (malaria) and Cryptosporidium parvum. The decrease in the rate of PCP in countries where patients with AIDS have access to HAART will present a significant challenge to the completion of this development program. The last published trial of PCP treatment was conducted by the ACTG in 24 U.S. sites between May 1991 and june 1993. That study needed to decrease the planned sample size to 195 due to low enrollment. This represents an important challenge for our program.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary efficacy endpoint will be the proportion of subjects with clinical success at the End of Treatment (Day 22) for the Modified Intent-to-Treat population (mITT).

    Measured: Day 22

Secondary outcomes (1)
  1. The secondary efficacy endpoints will be the proportion of subjects with clinical success at the End of Treatment (Day 22)for the Per Protocol population and sustained clinical success at the End of Study (Day 42)in the Per Protocol and mITT populations.

    Measured: Day 22

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Pafuramidine maleate (DB289) and Trimethoprim-Sulfamethoxazole (TMP-SMX) in people with Pneumonia, Interstitial Plasma Cell and Pneumocystis Carinii Pneumonia, run by Immtech Pharmaceuticals, Inc at 7 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 7 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: FDA Clinical Hold as of 12/21/07 due to safety concerns). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The primary efficacy endpoint will be the proportion of subjects with clinical success at the End of Treatment (Day 22) for the Modified Intent-to-Treat population (mITT). (time frame: Day 22). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Mar 2013.
