Sikkerheds- og acceptabel undersøgelse af en placebo-antistof-baseret ikke-hormonel svangerskabsforebyggende intravaginal ring
Sikkerheds- og acceptabelt undersøgelse af MM008-IVR, en antistofbaseret ikke-hormonel svangerskabsforebyggende intravaginal ring
In order to deliver nonhormonal vaginal contraceptive using anti-sperm antibodies, a new vaginal ring design using a capsule-IVR will be utilized. Evaluating the safety and acceptability of this device early in the product development cycle is important, not only because device/formulation characteristics become increasingly difficult to alter as product is advanced into clinical trials, but also because user adherence can directly impact clinical trial outcomes.

Detaljeret beskrivelse
There is a gap in commercially available reliable, effective contraception methods that do not contain hormones. Mucommune is developing a novel non-hormonal contraceptive in the form of a capsule-intravaginal ring (IVR) that releases highly potent contraceptive antibodies (MM008) that rapidly bind and trap sperm. These antibodies have been developed over the past 5 years and the target on sperm cells was initially obtained from a patient with infertility due to anti-sperm antibodies.

Device-only Tolerability and Acceptability
Tidsramme: 14 days
|
Device tolerability and acceptability as judged by scores on the questionnaires related to placebo IVR use. The scale that is used is a 5 point likert scale that assesses the degree to which the participant agrees or disagrees with a statement regarding the use of the intravaginal ring. Items will be factor analyzed and items will be summed by subscale with a higher score indicating greater agreement or a lower score indicating less agreement with a variety of statements about the ring and their experience of using the ring. |

Changes in Pro-inflammatory Cytokines
Tidsramme: 14 Days
|
Measures of proinflammatory cytokines at baseline and after placebo IVR use will be done using the ProcartaPlex Human Cytokine/Chemokine/Growth Factor Convenience Panel 1, 45plex. It allows for detection and quantification of up to 45 protein targets. This will be utilized to measure proinflammatory cytokines in the vaginal secretions. Increases in the proinflammatory cytokines indicate an increase in inflammation. |
