Effects of Progesterone on IV Nicotine-Induced Changes in Hormones and Subjective Ratings of Stimulant Drug Effect

Stopped: Clinical studies never started; funding not received.

United States0Started 2008-09

Plain-language summary

The proposed clinical studies will analyze the interactions between progesterone, nicotine, alterations in endocrine hormones, mood and cardiovascular measures. It is hypothesized that the administration of progesterone at a dose that mimics luteal phase levels in normal cycling women will diminish the positive subjective effects of nicotine, as has been consistently observed for cocaine. This novel approach could have direct implications for facilitating smoking cessation treatment in women of reproductive age

Inclusion Criteria: * Women between the ages of 18 and 40 who currently smoke at least 15 cigarettes every day, and who fulfill DSM-IV diagnostic criteria for nicotine dependence will be eligible for participation. * No evidence of clinically significant disease based upon complete medical history and physical examination supervised by Dr. Arthur Siegel (Chief of Internal Medicine). * Absence of DSM-IV Axis I Disorders other than nicotine dependence (305.10) as measured by the Structured Clinical Interview (SCID). * Routine laboratory blood tests including complete blood count, electrolytes, BUN and creatinine, liver function tests, hepatitis panel and urinalysis will be performed. Laboratory parameters must be within the normal range. HBsAg must be negative but subjects who have hepatitis serology consistent with previous exposure to Hepatitis A, Hepatitis B, or Hepatitis C, but who do not have clinical and biochemical evidence of acute infection, will be acceptable. * Hematocrit levels ≥ 35% for females. * Serum pregnancy test (hCG beta subunit) results must be negative within 24 hrs of the study session day. * Normal EKG. * A Body Mass Index (BMI-ratio of weight (W) to height (H) squared; W/H2=kg/m2) of between 18.0 and 27.0 for women. * Subjects must be able to read and understand instructions, as well as provide a valid informed consent.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
