What is being measured

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

  1. Percentage of Subjects With a Sperm Concentration < 15 Million Per mL by Treatment Week 26

    Percentage of Subjects with a Sperm Concentration < 15 million per mL by Treatment Week 26. Sperm concentration was calculated as measure of the number sperm per milliliter of semen. Duplicate semen samples were collected. The average of the 2 samples were used as the value for that scheduled collection period.

    Measured: Up to 26 weeks

Secondary outcomes (10)
  1. Percentage of Participants Who Entered the Observation Period and Did Not Return to Within 15% of Baseline Sperm Concentration or Above During the 52-Week Observational Period

    The percentage of participants who entered the Observational Period and did not return to within 15% of Baseline sperm concentration or above during the 52-week Observational Period. Duplicate semen samples were to be collected during the Observational Period. Sperm concentration was calculated as measure of the number sperm per milliliter of semen. Duplicate semen samples were collected. The average of the 2 samples were used as the value for that scheduled collection period.

    Measured: Up to 52 weeks after the Treatment Period

  2. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Sperm Concentration

    Duplicate semen samples will be collected during the Treatment and Observational Periods. The average of the 2 samples were used as the value for that scheduled collection period. A negative change from baseline indicated a decrease in sperm concentration.

    Measured: From Week 0 up to Treatment Period Week 26 and Observation Period Week 52

  3. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Sperm Motility

    Duplicate semen samples will be collected during the Treatment and Observation Periods. The average of the 2 samples were used as the value for that scheduled collection period. A negative change from baseline indicated a lower sperm motility (worsening).

    Measured: From Week 0 up to Treatment Period Week 26 and Observation Observation Week 52

  4. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Sperm Morphology

    Duplicate semen samples will be collected during the Treatment and Observational Periods. The percentage of sperm with normal versus abnormal morphology will be determined via microscopic analysis. A positive change from baseline indicates an improved sperm morphology.

    Measured: From Week 0 up to Treatment Period Week 26 and Observation Period Week 52

  5. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Semen Volume

    Duplicate semen samples will be collected during the Treatment and Observation Periods. The average of the 2 samples were used as the value for that scheduled collection period. A negative change from baseline indicated a decrease in semen volume.

    Measured: From Week 0 to up to Treatment Period Week 26 and Observation Period Week 52

  6. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Serum Testosterone

    Serum hormones levels will be tested during the Treatment and Observational Periods. A negative change from baseline indicated a decrease in serum testosterone.

    Measured: From Week 0 up to Treatment Period Week 26 and Observation Period Week 52

  7. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Estradiol

    Serum hormones levels were tested during the Treatment and Observational Periods. A negative change from baseline indicated a decrease in serum estradiol.

    Measured: From Week 0 up to Treatment Period Week 26 and Observation Period Week 52

  8. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Lutenizing Hormone (LH)

    Serum hormones levels will be tested during the Treatment and Observational Periods. A positive change from baseline indicated an increase in serum lutenizing hormone.

    Measured: From Week 0 to up to Treatment Period Week 26 and Observation Period Week 52

  9. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in in Follicle Stimulating Hormone (FSH)

    Serum hormones levels will be tested during the Treatment and Observational Periods. A positive change from baseline indicated an increase in serum follicle stimulating hormone.

    Measured: From Week 0 to Treatment Week 26 and Observation Week 52

  10. Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Inhibin B

    Serum hormones levels will be tested during the Treatment and Observational Periods. A negative change from baseline indicated a decrease in serum Inhibin B.

    Measured: From Week 0 up to Treatment Period Week 26 and Observation Period Week 52

This includes requests for clinical trial data for unlicensed products and indications.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Atrasentan in people with Nephropathy and Diabetes, run by AbbVie at 13 sites in 4 countries.

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 5 inclusion and 5 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: finished, as of the sponsor's last update on 7 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in United States, Italy, Germany, Spain. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Subjects With a Sperm Concentration < 15 Million Per mL by Treatment Week 26 (time frame: Up to 26 weeks). 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 May 2019.
