About this study

The goal of this observational study is to evaluate the epidemiological and clinical-pathological features of Philadelphia-negative myeloproliferative neoplasms through data from medical records

Read the detailed description

The investigators are proposing a study that provides descriptive understanding of patients with Philadelphia-negative myeloproliferative neoplasms in Ecuador. The primary objective of this pilot study is to lay the foundations for the development of a multicenter registry of Philadelphia-negative myeloproliferative neoplasms, which will provide high-quality real data and serve as a basis for the application to future projects and elaboration of public policies in the medium and long term.

What is being measured

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

  1. Number of patients with Philadelphia-negative Myeloproliferative Neoplasms in Ecuador

    Participants were followed-up for 8 years. This is the number of participants who have had Philadelphia-negative Myeloproliferative Neoplasms in Ecuador during the time of observation.

    Measured: 96 months

Secondary outcomes (3)
  1. Prevalence of Philadelphia-negative myeloproliferative patients

    Calculation of the prevalence of participants who have had Philadelphia-negative Myeloproliferative Neoplasms in Ecuador during the time of observation.

    Measured: 96 months

  2. Mortality risk as measured by the Dynamic International Prognostic Scoring System

    The Dynamic International Prognostic Scoring System (DIPSS) was proposed and validated by Passamonti and is used as a prognostic model to predict survival in participants with Primary Myeloid Fibrosis a Philadelphia-negative myeloproliferative neoplasm.

    Possible scores range from 0 to 6, with higher scores indicating higher mortality risk.

    Measured: 96 months

  3. Overall survival

    Percent of participants with Primary Myeloid Fibrosis who were alive at 96 months of follow-up

    Measured: 96 months

Questions about this trial

What is this clinical trial studying?

An observational study of Myeloproliferative Neoplasm and Myeloproliferative Syndrome, run by Sociedad de Lucha Contra el Cáncer del Ecuador at 1 site in Ecuador.

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 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 27 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Ecuador. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of patients with Philadelphia-negative Myeloproliferative Neoplasms in Ecuador (time frame: 96 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05825326, which also lists 6 linked publications.

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 27 Apr 2023.
