What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Follitropin deltaDrug
Also called FE 999049, REKOVELLE
Single daily subcutaneous administration through pre-filled injection pen
Follitropin betaDrug
Also called FOLLISTIM
Single daily subcutaneous injection in the abdomen
| Study group | Role | What they receive |
|---|---|---|
| Follitropin delta | Experimental | FE 999049 was administered as single daily subcutaneous injections in the abdomen. Participants randomized to FE 999049 had their individual dose determined on the basis of their anti-Müllerian hormone (AMH) level at screening and their body weight at randomization. The daily FE 999049 dose was fixed throughout the stimulation period. The minimum allowed daily FE 999049 dose was 6 μg and maximum allowed daily dose was 12 μg. Dosing continued until the criterion for triggering of final follicular maturation was met. Participants could be treated for a maximum of 20 days. Receives: Drug: Follitropin delta |
| Follitropin beta | Active comparator | FOLLISTIM was administered as single daily subcutaneous injections in the abdomen. The starting dose of FOLLISTIM was 150 IU and fixed for the first five stimulation days, after which it could be adjusted by 75 IU based on the individual response. The maximum allowed daily dose was 375 IU. Dosing continued until the criterion for triggering of final follicular maturation was met. Participants could be treated for a maximum of 20 days. Receives: Drug: Follitropin beta |

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?

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 Oocytes Retrieved (time frame: 36h (± 2h) after triggering of final follicular maturation (On day of oocyte retrieval)). 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 NCT03228680, which also lists 3 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?
