Intervention/exposure

Study type

Interventional

Description of intervention(s) / exposure

The Alyra intrauterine device – contains ~37mg of levonorgestrel releasing approximately 9.6 micrograms per 24 hours and ~27 mg of amitriptyline releasing approximately 0.35 mg per 24 hours. The device will be inserted by a specialist Gynaecologist highly experienced in the placement of IUDs in the general population. The Alyra intrauterine device is placed in exactly the same way, and by the same procedures and practices, as that with a standard Mirena 'Trademark' device. Only study approved Gynaecologists are able to place the Alyra device. The total duration of IUD placement is 84 days (~ 3 months). Throughout the duration of the study, you will attend onsite visits for frequent safety and monitoring checks. These checks will ensure that the device is positioned correctly and are designed to answer any queries that you may have as the study arises. You will also be given a participant information card containing the contact details of your study Gynaecologists, should you need to contact them at any time in regard to your study IUD. Following insertion of the device, participants will complete a daily study specific APP to monitor their experiences of the device.

Comparator / control treatment

This study will investigate the in-vivo pharmacokinetics of the Alyra device compared with the currently approved TGA standard Mirena IUD as a market comparator, and provide initial safety data for the Alyra device. The Mirena device releases levonorgestrel (a progesterone hormone) as a component of the contraceptive method. In this device levonorgestrel is released at 20 micrograms into the uterine cavity per 24 hours following insertion. Following insertion of the Alyra or Mirena devices, participants will complete a daily study specific APP to monitor their experiences of the device. As this device is the comparator, it will also be monitored for the drug release rate levels of levonorgestrel, over 84 days (~ a 3 month period).

Outcomes

Primary outcome [1]

Among participants with pre-existing dysmenorrhea-related pelvic pain, the objectives of this study are as follows: To confirm that blood assays for amitriptyline and levonorgestrel are sufficiently sensitive to guide further pharmacokinetics investigations

Timepoint [1]

PK samples will be collected and compared at 3, 6, 9, and 12 hours post-insertion, then daily for 7 days, then again on day 14, 28, 56 and 84, after intervention commencement. PK samples of amitriptyline and levonorgestrel will be collected as whole blood samples however they will be analysed as plasma concentrations. Parameters to be examined are: Cmax, tmax, AUC0-last, Cav.

Primary outcome [2]

To investigate the tolerability of the Alyra Device when compared with the Mirena 'Trademark' Device

Timepoint [2]

At device removal on day 84 the following will be compared:
- number of days of pelvic pain reported per 28-day time periods post device insertion.
- average daily severity of pelvic pain (derived from days when pain was reported) for each of the three 28-day time periods post insertion.
- number of days of uterine bleeding/spotting per 28-day time periods post insertion.
- pelvic pain AUC28day for each of the three 28-day time periods post insertion.

Secondary outcome [1]

To compare the release of amitriptyline and levonorgestrel from the Alyra Device and the Mirena 'Trademark' Device by measuring the amount of amitriptyline and levonorgestrel left in the devices after removal at completion of the study.

Timepoint [1]

At device removal on day 84. THF extraction to be carried out on remaining amitriptyline, nortriptyline and levonorgestrel concentrations present in study devices at study end.

Secondary outcome [2]

To investigate the effect of the Alyra Device on the endometrium using endometrial biopsies

Timepoint [2]

Endometrial biopsies will be compared from baseline, to device removal day and then to one menstrual cycle post device removal.

Phase

Phase 1

Type of endpoint/s

Pharmacokinetics / pharmacodynamics

Statistical methods / analysis

Statistical planning has been undertaken in consultation with Dr Elisa Young from Accelagen.

Pharmacokinetics participants:
Plasma amitriptyline, nortriptyline and levonorgestrel parameters to be analysed as: Cmax, tmax, AUC0-last, Cav.

Pharmacokinetics devices:
THF extraction of remaining amitriptyline, nortriptyline and levonorgestrel present in study devices at study end.

Participant Tolerability Outcomes:
Mixed model for repeated measure (MMRM) analyses to compare the change from baseline over the treatment period between the two treatment groups for the following:
- number of days of pelvic pain reported per 28-day time periods post device insertion at 4, 8. and 12 weeks.
- average daily severity of pelvic pain (derived from days when pain was reported) for each of the three 28-day time periods post insertion.
- number of days of uterine bleeding/spotting per 28 days time periods post insertion.
- pelvic pain AUC28day for each of the three 28-day time periods post insertion.
The model for each parameter will include treatment, time (4,8 and 12 weeks) and an interaction between treatment and time, as fixed effects baseline values as a covariate and subject as a random effect. Treatment differences will be estimated using least square means difference and 95% two-sided confidence intervals. The treatment effect will be estimated for each timepoints as well as the overall study period, with the same weight applied to the treatment effects for each timepoints.

Summary

Brief summary

Alyra Biotech Pty Ltd is an Australian-owned biopharma company that wishes to develop an optimal intrauterine contraceptive device (IUD) for people with period or pelvic pain. The use of IUDs globally is increasing, however some people experience increased pelvic pain in the 3-6 months following insertion, causing them to have the device removed. They then miss out on the benefits that IUDs can provide, such as; reducing your lifetime exposure to synthetic hormones; decreasing the amount of blood loss at each period; as well as decreasing intense period pain, over time with continual use.

Alyra Biotech Pty Ltd has developed and patented a novel IUD designed to reduce the severity of post-insertion pain in those that experience it, giving them access to the benefits of IUD use.

The objectives of this study are:
1. To determine how the device performs at releasing the appropriate medicinal drugs (pharmacokinetics).
2. To compare the tolerability of the new Alyra device with the currently approved for use in Australia, the Mirena 'Trademark" device.
3. To determine how much of the medicinal drugs are remaining in the device at study end.
4. To determine the effects of the Alyra Device on the endometrium using endometrial biopsies.

Public notes

Alyra Biotech has developed a novel IUD that provides sustained release of the TLR4 inhibitor, amitriptyline, to modulate immune activation within the uterus to reduce pelvic pain in women. (those who have pelvic pain experience increased activation). It is thought that by adding a small amount of amitriptyline directly to an IUD, that there may be reduced pain experienced after the device is inserted. It is also thought that as the dose of amitriptyline released to the body each day will be low, so that fewer people will experience the side effects usually seen when given an oral dose. The dose of amitriptyline released from the Alyra Device each day is estimated to be between 0.3 and 1.0mg per day. Taken orally for pain relief, the prescribed dose would usually be between 10 and 100 mg per day. As standard IUDs use levonorgestrel (a progesterone hormone as a contraceptive method), the Alyra Device will also release levonorgestrel. A study APP will be used by participants to gain frequent insight into their experiences using the device. As this device is new, this study will be used to test the drug release rates (of both amitriptyline and levonorgestrel) into the user for a period of 84 days (3 months), as well measuring the amount that is left over in the device after device removal at 84 days.
