About this study

Official title: Effects of Decrease in Cholesterol Levels Induced by a Statin on Sperm Quality

Recently, concerns about the effect of atorvastatin intake on men fertility have been raised. However, this statin has never been investigated regarding its influence on male fertility, notably sperm quality.

The aim of this pilot study is to evaluate the efficacy and the safety of a decrease of cholesterol blood levels, induced by taking atorvastatin, on sperm quality of normocholesterolaemic and healthy men without confounding factors.

Read the detailed description

The main objective is to estimate the safety of atorvastatin on fertility of normocholesterolaemic and healthy men (having normal blood lipid profile and normal sperm parameters) by analyzing its effects on sperm parameters: ejaculate volume, sperm count, total and progressive motility, percentage of typical forms.

The secondary objectives are to assess the changes in:

  • hormonal profile: gonadotropins and testosterone plasma levels
  • lipid composition of sperm and seminal fluid;
  • spermatozoa capacitation markers
  • accessory glands markers.

The efficacy is estimated by measuring the lipid lowering action of atorvastatin. It is expected a decrease by 20 and 40% of total cholesterol blood and LDL-cholesterol levels, respectively (total cholesterol <1.5 g / l and LDL-cholesterol <1g / l).

Considering this protocol as a pilot study to evaluate safety and efficacy, sample size estimation was fixed considering a Fleming design at one stage. These designs with one group and multi-stages (between 1 and 5) can be seen as filtering steps leading to the decision type go/no go. With a type I error a and statistical power (1-β) equals respectively 5% and 90%, n=17 subjects were necessary to reject the hypotheses of minimal (p=0.85) and maximal (p=0.95) acceptable non-toxicity. If 1 subject or more presented a toxicity, the treatment was considered no safe. To measure the evolution of total cholesterol and LDL-cholesterol levels concerning the efficacy, n=17 subjects were necessary to show a minimal paired difference (to be detected) of 0.5 with expected standard-deviation of difference = 0.5, correlation coefficient of 0.5, a= 5% (two-sided) for a power greater than 90% (1-β=97%).

Subjects are included after a screening visit (visit 0), during which routine laboratory biochemical tests are performed, an electrocardiogram is taken, blood pressure, weight and height are measured; physical examination including testis evaluation and semen parameters are analyzed according to WHO standards 1999 .

The subjects take atorvastatin orally (10mg/day (d), Tahor©, Pfizer Laboratory) during 5 months allowing to study atorvastatin effects on human spermatogenesis and epididymal maturation (one cycle requiring approximately 3 months).

Blood and semen parameters were measured :

  • before to take atorvastatin treatment (visit 1)
  • at the end of the therapy (visit 3)
  • and 3 months after the end of treatment, (visit 4) to perform measurements during different cycles of spermatogenesis on a same subject. After two months of treatment, a consultation (visit 2) is realized to ensure good tolerance to treatment and to control treatment efficiency.

Biochemical clinical and semen measurements take before treatment were considered as "control baseline measures".

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Atorvastatin in people with Healthy Volunteers and Normocholesterolaemic Men, run by University Hospital, Clermont-Ferrand at 1 site in France.

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 7 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 21 Mar 2014. 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 France. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 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?

Observations of all modifications on semen quality after 5 months of atorvastatin treatment (time frame: at month 5). The study lists 2 primary outcomes in all. 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 NCT02094313, which also lists 1 linked publication.

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 21 Mar 2014.
