Study Title:

Clinical Evaluation of Daily Application of Nestorone® (NES) and Testosterone (T) Combination Gel for Male Contraception.

 

Study Objectives:

The overall goal of this study is to develop a hormonal contraceptive method for men that is effective, safe, reversible, self-delivered, user-controlled and affordable. The objective of this study is to determine whether application of a combined gel containing an androgen, Testosterone (T), and a progestin, Nestorone®, applied transdermally once per day will suppress spermatogenesis and be effective as a contraceptive method in healthy couples who wish to avoid pregnancy and are willing to use the method as their primary method of birth control.

Primary objective
The primary objective of the study is to determine the contraceptive efficacy for a couple provided by continued daily application by the male partner of a gel containing testosterone (T) and Nestorone (NES) for a period of 52 weeks (about 12 months).
 
 Secondary objectives
The secondary objectives of the study are to assess safety and acceptability of the NES 8 mg/day + T 62 mg/day (NES-8/T-62) gel.

Laymans Summary:

Forty percent (40%) of preg- nancies globally are un- planned. Many women are unable to use hormonal con- traceptives due to the side effects.  International surveys show that men are interested and willing to use male contracep- tion to support their female partners

Current contraception options available for men are con- doms and vasectomies.
More options are needed to support men in meeting their contraceptive needs.
 
OUR STUDY
We are conducting and international, multicenter clinical trial study for male birth control. Our Mission is to develop safe and effective contraception for men.
The primary objective of our study is to determine contracep- tive efficacy for a couple provided by daily application by the male partner of a gel containing testosterone (T) and Nestorone (NES) .
The couples will be in the study for 2 years to test the safety and efficacy of the study gel
Study Goal:
To develop new forms of birth control for men that are:
• Safe
• Reversible
• May be self-delivered
• Affordable
• Have health benefits for men

Abstract of Study:

Safe and Effective Contraception is a universal right for all men and women. Many women of reproductive age are unable to  use the current contraception methods available to them and rely on their male partners to protect them from unplanned pregnancy.  A majority of men surveyed internationally reported interest and willingness to use contraceptive methods; unfortunately no safe, highly effective reversible method is available to men interested in sharing the responsibility of family planning.The primary objective  of the CCN017 male contraception study is to determine the contraception efficacy, safety and acceptablily for a couple provided by daily application of the male partner of a gel containing Nesteron 8mg and Testesterone 62mg (NES 8/T 62) for a period of 52 weeks

Methodology

This is a prospective, phase IIb, open label, single arm, multicenter study. The study consists of a screening phase lasting 4 to 8 weeks, a suppression phase estimated to last up to 20 weeks, a 52- week maintenance/efficacy phase, and a 24-week (estimated) recovery phase.  The study population will comprise healthy men ages 18 – 50 years, involved in a stable, monogamous, relationship  with an 18 – 34 year-old female partner (at the time of enrolment) with regular cycles per patient report from her previous non-hormonal contraceptive gynecology history. Across all sites, the study will enrol 420 couples into the suppression phase. The Couples Counselling Clinic will aim to enrol 60 couples into the suppression phase.Questionnaires will be administered during the study in the Couples Counselling Clinic, with the exception of the 7-Day Validated Psychosexual Daily Questionnaire that will be completed by the participant at home.  Blood samples for laboratory analyses will be collected at visits throughout each phase of the study for processing at both the central laboratory and at Pathology Lancet Kenya.

Informed Consent

The principles of informed consent will be implemented according to the Declaration of Helsinki in its currently acknowledged version, ICH Consolidated Good Clinical Practice, KNH/UON Ethics Review committee.   Participants male and female, that agree to voluntarily participate in the study must sign the informed consent form (ICF) prior to study-specific procedures.

Synopsis: Rationale, Background, Risks and Benefits

NES is a synthetic progestin structurally related to progesterone that does not have any androgenic, estrogenic or glucocorticoid activity at therapeutic doses (Sitruk-Ware, 2006) and is therefore not expected to have some of the undesirable side effects of levonorgestrel or desogestrel, such as weight gain or mood changes.

NES is a synthetic progestin structurally related to progesterone that does not have any androgenic, estrogenic or glucocorticoid activity at therapeutic doses (Sitruk-Ware, 2006) and does not interact with GABA-Receptors (Kumar et al, 2017). It is therefore not expected to have some of the undesirable side effects of levonorgestrel or DMPA, such as weight gain or mood changes.

Synopsis: Study Design

This is a prospective, phase IIb, open label, single arm, multicenter study. The study protocol consists of a screening phase lasting 4 to 8 weeks, a suppression phase estimated up to 20 weeks, a 52-week maintenance/efficacy phase, and a 24- week (estimated) recovery phase. Detailed procedures about each of the study phases are listed in protocol Section 14.

The study will involve approximately 420 couples recruited throughout the CCTN that meet eligibility criteria. The nine sites propose to enroll up to 420 couples (about 30 to 60 couples per site) with a goal of obtaining 200 couples completing the contraceptive efficacy phase of the study. The study has four phases (screening phase, suppression phase, efficacy phase and recovery phase) with monthly visits to provide the male participants with the NES-8/T-62 gel, to encourage adherence, to monitor for possible side effects, and to quantify semen parameters. The female will be contacted monthly and come in for a visit every three months.

The female partner will be contacted monthly and come in for a visit every three months. Male subjects will be treated and followed as outpatients, along with their participating female partner.

Based on results from earlier studies, this fixed dose combination of T and NES is estimated to be the optimal fixed dose for men to achieve azoospermia with adequate replacement of T. It is possible that the T dose in this hormonal contraceptive gel could be too much for some men or too little for other men. Male subjects’ T level will be followed in the first 12 weeks of the study to confirm this as the optimal fixed dose for most participants.

Male subjects who have a Visit 3A/Week 2 and Visit 4/Week 4

serum T value <200 ng/dL (6.9 nmol/L), with reported gel application adherence, will be offered the choice to take part in a Supplemental Testosterone Substudy. Male subjects who elect to take part in the Supplemental Testosterone Substudy will receive supplemental T gel (20 mg with Androgel 1.62% or 25 mg of Androgel 1% or equivalent Testogel) in order to maintain serum T within the normal range. The supplemental T gel will be applied to either the right or left upper back and arms. Subjects who meet the criteria of low T to participate in the Supplemental Testosterone Substudy and decline to do so will be considered no longer eligible and discontinued unless a waiver is approved in specific cases with borderline serum T and without specific symptoms.

4. Study Design

The female will be contacted monthly and come in for a visit every three months.

Couples who meet the eligibility requirements will begin the suppression phase estimated to last up to 20 weeks during which study treatment will be administered in order to obtain suppression of sperm concentration to 1 million/mL (potentially longer if sperm is trending toward required suppression). If sperm suppression is successful, couples will move into the 52- week efficacy phase where study treatment is continued.

The female partner will be contacted monthly and come in for a visit every three months.

If sperm suppression is successful, couples will move into the 52- week efficacy phase where study treatment is continued. Male subjects will be treated and followed as outpatients, along with their participating female partner.

4. Study Design

Previous text unchanged.

Based on results from earlier studies, this fixed dose combination of T and NES is estimated to be the optimal fixed dose for men to achieve azoospermia with adequate replacement of T. It is possible that the T dose in this hormonal contraceptive gel could be too much for some men or too little for other men. Male subjects’ T level will be followed in the first 12 weeks of the study to confirm this as the optimal fixed dose for most participants.

Male subjects who have a Visit 3A/Week 2 and Visit 4/Week 4 serum T value <200 ng/dL (6.9 nmol/L), with reported gel application adherence, will be offered the choice to take part in a Supplemental Testosterone Substudy. Male subjects who elect to take part in the Supplemental Testosterone Substudy will receive supplemental T gel (20 mg with Androgel 1.62% or 25 mg of Androgel 1% or equivalent Testogel) in order to maintain serum T within the normal range. The supplemental T gel will be applied to either the right or left upper back and arms. Subjects who meet the criteria of low T to participate in the Supplemental Testosterone Substudy and decline to do so will be considered no longer eligible and discontinued unless a waiver is approved in specific cases with borderline serum T and without specific symptoms.

Male subjects who have a serum T level 200 ng/dL (6.9 nmol/L) and <250 ng/dL (8.68 nmol/L) with reported gel application adherence and a low T symptom (refer to Appendix 14 for definition) at both Visit 3A/Week 2 and Visit 4/Week 4 will have the option to take part in the Supplemental Testosterone Substudy or be discontinued.

If a male subject presents with a low T symptom (refer toAppendix 14 for definition) after Visit4/Week 4 through Visit 7/ Week 12, with reported gel application adherence, serum T levels will be obtained and tested locally. If levels are <250 ng/dL (8.68 nmol/L), they will be repeated. If a second consecutive level is <250 ng/dL (8.68 nmol/L), male subjects will have the option to take part in the Supplemental Testosterone Substudy or be discontinued. No subjects may enter the Substudy after Visit 7/Week 12.

Following Visit 7/Week 12, should a male subject present with a low T symptom (refer to Appendix 14 for definition), the study team will review and discuss with the subject the importance of applying the gel every day, the washing instructions, and review the area of application. If protocol compliance and gel application adherence is confirmed, the subject will be evaluated for the low T symptom per standard of care and Investigator

8. Study Duration

Subject recruitment is expected to begin Q2 2018 and is planned to continue through Q2 2019. However, if the enrollment rate declines, the enrollment period may be extended beyond this date. If this enrollment timeline is met, all male subjects should finish suppression treatment by approximately the beginning of Q3 2019, efficacy phase by Q4 2020 and recovery phase by Q3 2021. Therefore, the total duration of the study, including study initiation, will be approximately 4.25 years for each study site. The end of the study will occur when the last male subject to be enrolled has completed his Exit Visit and all data is entered on the appropriate CRF pages.

Results of the study are expected to be available Q1 2022.

13.2.9 In-Depth Interview

Section not present.

All participants will be invited to complete an in-depth interview (IDI) before exiting from the study. Depending on participant availability and visit length, it may be necessary to conduct this assessment as a separate visit or call. The interview process will interview each male and female participant individually and then together. The IDI will address experience with study product use and acceptability during the trial. In-depth interview data on gel application instructions, sperm and T level testing requirements as well as other components of acceptability and factors affecting adherence will be collected during the IDI. These IDIs will be conducted by a trained qualitative interviewer and will follow a semi-structured questionnaire guide and are anticipated to last approximately 30 minutes for each individual interview and then 30 minutes together for a total of 1.5 hours per couple. These IDIs may be conducted over the phone. The audio from the IDI will be recorded, summarized and transcribed for analysis. The interview notes, audio recordings and transcripts will be considered as source documentation.

14.2.1 Male Partner

During the suppression phase, the following assessments will be performed for the male partner:

Safe and Effective Contraception is a universal right for all men and women. Many women of reproductive age are unable to  use the current contraception methods available to them and rely on their male partners to protect them from unplanned pregnancy.  A majority of men surveyed internationally reported interest and willingness to use contraceptive methods; unfortunately no safe, highly effective reversible method is available to men interested in sharing the responsibility of family planning.The primary objective of the study is to determine contraceptive efficacy for a couple provided by daily application by the male partner of a gel containing testosterone (T) and Nestorone (NES) for a period of 52 weeks (about 12 months).

The secondary objectives of the study are to assess the safety and acceptability of the NES 8 mg/day + T 62 mg/day (NES-8/T-62) gel and the NES 8 mg/day + T 74 mg/day (NES-8/T-74) gel for a period of 52 weeks.

Methodology

This is a prospective, phase IIb, open label, single arm, multicenter study. The study consists of a screening phase lasting 4 to 8 weeks, a suppression phase estimated to last up to 20 weeks, a 52- week maintenance/efficacy phase, and a 24-week (estimated) recovery phase.  The study population will comprise healthy men ages 18 – 50 years, involved in a stable, monogamous, relationship  with an 18 – 34 year-old female partner (at the time of enrolment) with regular cycles per patient report from her previous non-hormonal contraceptive gynecology history. Across all sites, the study will enrol 420 couples into the suppression phase. The Couples Counselling Clinic will aim to enrol 60 couples into the suppression phase.Questionnaires will be administered during the study in the Couples Counselling Clinic, with the exception of the 7-Day Validated Psychosexual Daily Questionnaire that will be completed by the participant at home.  Blood samples for laboratory analyses will be collected at visits throughout each phase of the study for processing at both the central laboratory and at Pathology Lancet Kenya.

Informed Consent

The principles of informed consent will be implemented according to the Declaration of Helsinki in its currently acknowledged version, ICH Consolidated Good Clinical Practice, KNH/UON Ethics Review committee.   Participants male and female, that agree to voluntarily participate in the study must sign the informed consent form (ICF) prior to study-specific procedures.
