The Effects of an Estrogen Receptor (ER) Beta Agonist (Lilly Compound LY500307) on Estradiol-withdrawal-induced Mood Symptoms in Women With Past Perimenopausal Depression.

Background:

Some women who had depression in the perimenopause may have mood symptoms again if they stop
estrogen therapy. Estrogen acts in the brain and other tissues by binding to at least three
types of estrogen receptors. One of these receptors, estrogen receptor beta may affect
anxiety and depression. The drug LY500307 acts only on this receptor. In this study,
researchers will initially give you estrogen and then suddenly stop estrogen after three
weeks. Then they will study how LY500307 affects mood symptoms.

Objectives:

To study how withdrawing estradiol affects mood. To test the safety and side effects of
LY500307.

Eligibility:

Healthy women ages 45-65 who had depression related to perimenopause in recent years and
whose mood systems got better with estradiol

Design:

-Participants will be screened with:

Medical history

Physical exam

Blood tests

Psychiatric interview

Gynecological exam

- Participants able to get pregnant must use effective barrier birth control throughout
the study.

- During the first 3 weeks, participants will wear an estrogen patch. It is 1x2 inches and
will be replaced every 3 days.

- For the next 3 weeks, participants will take 3 study capsules every morning. They will
not know if they get the study drug or placebo.

- Some participants will also take a progesterone-like drug for 1 week at the end of the
medication phase of the study.

- Participants will have 9 one-hour study visits. They will have blood samples and vital
signs taken. They will answer questions about mood and behavior symptoms.

- Participants will keep a daily log of these symptoms.

- Participants will have 2 transvaginal ultrasounds. A probe is temporarily placed 2-3
inches into the vaginal canal and sound waves are used to create pictures of the lining
of the uturus.

- Participants will have a final visit 4 weeks after stopping the study drug. They will
answer questions about mood and side effects.

OBJECTIVE:

During the perimenopause, the incidence of depression increases 1-5 and predicts increased
all-cause and cardiovascular mortality. A role of estradiol withdrawal in the onset of mood
disorders in some perimenopausal women has been suggested indirectly by estradiol s
antidepressant efficacy and safety in perimenopausal depression. Moreover, observational
studies report the emergence of depressive symptoms after the discontinuation of menopausal
hormone therapy (HT) in 5-10% of women. The coincidence of declining ovarian function with
the onset of depression led to the inference that withdrawal from physiologic estradiol
levels underpinned depression during the perimenopause. To test this inference, we undertook
a study to examine the role of estradiol withdrawal in perimenopausal depression. We
evaluated the effects of the acute withdrawal of estradiol therapy in postmenopausal women
with and those without a past perimenopausal depression. Results demonstrated that estradiol
withdrawal induces depressive symptoms in women with a past perimenopausal depression, but
not in those without such a history. This study was the first to provide direct evidence that
estradiol withdrawal is the relevant physiologic trigger for depressive symptoms in women
with this condition. In women with past perimenopausal depression, the recurrence of
depressive symptoms during blinded hormone withdrawal suggests that normal changes in ovarian
estradiol secretion can trigger an abnormal behavioral state in these susceptible women.
These data also suggest that the effects of estradiol withdrawal are processed differently in
some women, presumably by altering the brain network composition or activity that underlies
affective state. In this next protocol, we will examine a possible mechanism mediating the
effects of estradiol- withdrawal on mood symptoms in asymptomatic postmenopausal women with a
past perimenopausal depression. We propose to evaluate the efficacy and safety of a selective
estrogen receptor (ER) beta agonist (Lilly Compound LY500307) to prevent estradiol
withdrawal-induced mood symptoms. The effects of estradiol primarily occur through activation
of two receptor subtypes, often with opposing outcomes: estrogen receptor (ER) alpha, and ER
beta. We focus on ER beta because the beta estrogen receptor is reported to mediate the
effects of estradiol on the serotonergic system and mediate the antidepressant-like effects
of estradiol in the forced-swim test. Moreover, selective agonists of estrogen receptor beta
have been demonstrated to attenuate the behavioral and hypothalamic-pituitary- adrenal (HPA)
axis response to stress in animal studies. We propose to employ the selective estrogen
receptor agonist LY500307 under double-blind, placebo controlled conditions to examine the
specific role of estrogen receptor beta in the effects of estrogen withdrawal in women with a
past perimenopause-related depression. Depressive symptoms will be measured with standardized
ratings scales (i.e., Center for Epidemiologic Studies Depression scale (CES-D) and 17-item
Hamilton Rating Scale of Depression (HRSD)). Results of this study will determine the role of
ER beta in estradiol withdrawal-induced mood symptoms and can provide preliminary data to
support the efficacy and safety of this compound as a treatment for depression during the
perimenopausal transition.

- INCLUSION CRITERIA:

1. Women with a past perimenopause-related depression (within 10 years). The
diagnosis of perimenopause-related depression will be based on a history of a
past depressive episode (major or minor depression confirmed by Structured
Clinical Interview for DSM-V (SCID)) at midlife in association with menstrual
cycle irregularity (and possibly hot flushes and/or vaginal dryness) and in whom
menopausal hormone therapy was reported to improve their depression at any time
within the prior ten years. All women participating in this protocol will have
previously completed the screening protocol # 88-M-0131 during which psychiatric,
medical, and reproductive evaluations will be performed and they will have been
confirmed to be in good medical health.

2. Age 45 to 65

3. Medication free (including no mood stabilizers, no sleep medication) except for
the following: women on menopausal hormone therapy who will discontinue these
medications at the start of this study and have their hormone therapy replaced
with estradiol 100mcg per day (as described below), women who are on stable doses
of thyroid replacement for at least six months prior to study enrollment, or
women who occasionally take non-steroidal anti-inflammatory drugs [NSAIDs] or
allergy medications (although we will ask women to minimize the use of these
medications during the study).

4. Subjects must have consent capacity

EXCLUSION CRITERIA:

The following conditions will constitute contraindications to participate in this protocol:
