18 Clinical Trials for Various Conditions
A Phase 3 clinical trial of oral GnRH antagonist pre-treatment for women with endometriosis who are undergoing IVF, with a primary outcome of live birth rate. The investigators' central hypothesis is that in infertile woman with endometriosis undergoing in vitro fertilization-embryo transfer (IVF-ET), live birth rates will improve in those pretreated with GnRH antagonist compared to those not pretreated with GnRH antagonist.
The goal of this clinical trial is to measure the toxicity and effectiveness of the following treatments for cFIR/cgUIR prostate cancer patients. Stereotactic body radiotherapy (SBRT) alone or Stereotactic body radiotherapy (SBRT) combined with Ultrashort GNRH Antagonist called Relugolix (an oral drug). Treatments will be randomly assigned to study patients. The main questions it aims to answer are the following: 1. Whether the proportion of men who undergo SUGAR have a superior rate of attaining PSA nadir of \<= 0.2 compared to SBRT alone, and 2. Whether SUGAR is superior to historical rates of minimal clinically important decline (MCID) in sexual and hormonal function at 6 months for patients undergoing 6 months of androgen deprivation therapy (ADT) Men aged 18+ with cFIR/cgUIR will be enrolled. Specifically, patients must meet one of the following 2 criteria: 1) Gleason score must be Gleason 3+4 with a PSA \< 20 ng/mL, or 2) Gleason 6 (3+3) and PSA \> 10 ng/mL and \< 20 ng mL.
The purpose of this research study is to determine if treatment with Elagolix will improve body weight, waist circumference, muscle strength, cortisol secretion, blood glucose, cholesterol, and bone quality as well as mood and quality of life in a female patient with mild hypercortisolism from adrenal overproduction of cortisol. Many people with adrenal nodules, or non-cancerous growths in the adrenal glands, have mildly elevated cortisol levels. Cortisol is a hormone normally made by the adrenal glands. It is increasingly being recognized that even mild elevations in cortisol levels can negatively impact blood glucose levels, serum cholesterol levels, weight and other metabolic parameters. This can lead to an increase in risk for cardiovascular disease. The study team is trying to determine if the medication Elagolix might be an effective treatment for post-menopausal females with mild hypercortisolism. Elagolix is a medication used to treat a medical condition called endometriosis by decreasing the body's production of sex hormones. Growth of adrenal adenomas is thought to be driven by such sex hormones. Therefore, by decreasing production of these hormones, the study team hopes to treat hypercortisolism caused by adrenal adenomas.
This is a prospective cohort study comparing the novel FDA-approved oral GnRH antagonist ORIAHNN (elagolix, estradiol, and norethindrone acetate capsules; elagolix capsules) to uterine artery embolization (UAE) or myomectomy (abdominal, laparoscopic, or hysteroscopic) for treatment of heavy menstrual bleeding due to leiomyomas. Uterine leiomyomas, also called fibroids, are hormone-dependent growths in the uterine muscle that are common in reproductive-age women (1). Leiomyomas can often lead to heavy menstrual bleeding. Definitive treatment for abnormal uterine bleeding due to leiomyomas is hysterectomy, but for patients who desire uterine conservation, a variety of treatment options exist. Regulation of menses with combined oral contraceptives or progestin only oral formulations are generally considered first line treatment but are not curative or effective for many patients. Another treatment option is a myomectomy, which is the surgical resection or removal of myomas. Myomectomy can be performed via hysteroscopy or laparoscopy, or by a vaginal or an abdominal approach. The route of removal depends on myoma location and patient symptoms. Another treatment option is Uterine fibroid or uterine artery embolization (UFE/UAE). UAE is a minimally invasive procedure where permanent particles are delivered to and block/embolize the blood supply to the myoma via a fluoroscopy directed arterial catheter. This typically leads to a decrease in fibroid size and associated bleeding (2). ORIAHNN, an oral GnRH antagonist that was FDA-approved in 2020, has demonstrated significant decrease in myoma-associated heavy menstrual bleeding compared to placebo (1) but has not been compared to other standard of care interventions. The primary objective of this study is to compare this novel medication to the common AUB-L treatments UAE and Myomectomy.
A Phase 3 clinical trial of oral GnRH antagonist pre-treatment for women with endometriosis who are undergoing IVF, with a primary outcome of live birth rate. The investigators' central hypothesis is that in infertile woman with endometriosis undergoing in vitro fertilization-embryo transfer (IVF-ET), live birth rates will improve in those pretreated with GnRH antagonist compared to those not pretreated with GnRH antagonist.
The purpose of this trial is to demonstrate non-inferiority of MENOPUR® versus recombinant Follicle Stimulating Hormone (rFSH) (Gonal-f®) with respect to ongoing pregnancy rate in women undergoing controlled ovarian stimulation (COS) following GnRH treatment.
Disprove the null hypothesis as follows: Among the investigator's egg bank donors undergoing ovulation induction with recombinant FSH medication per treatment protocol outlined below, use of adjunctive LH activity medication Menopur ™ , will result in the same number of mature oocytes recovered and cryopreserved as from egg donors not treated with Menopur™. Objectives: Compare efficacy of recombinant FSH (Follistim ™) with and without adjunct LH activity medication Menopur ™ for our volunteer egg bank donors. Efficacy defined as: 1. #Days of ovarian stimulation to GnRH agonist trigger. 2. Peak serum estradiol level on day of GnRH agonist trigger. 3. Number of follicles \>15 mm average diameter on day of GnRH agonist trigger. 4. Number of mature oocytes recovered and cryopreserved. Study type: Randomized prospective clinical trial. Patient selection: Voluntary egg donors who have satisfied all screening criteria for FDA and the Michigan Egg Bank: Age range 18-to 39 years. BMI 18 to 25. Resting antral follicle count of 16 or greater. Cycle day 3 FSH \<10 mIU/ml. AMH \>2.0 ng/ml. Study design: Two groups- Group A- Recombinant FSH Follistim only; Group B- Recombinant FSH Follistim and adjunct Menopur. Both groups will use GnRH agonist trigger 36 hours prior to egg retrieval. Random number generator with patients assigned basd on odd or even numbers. Number of subjects: 25 in each group. Total of 50 subjects. This takes into account possible cycle cancellation for poor ovarian response or patient elective withdrawal to result in at least 20 subjects in each group completing the study. Primary measure of outcome: number of mature oocytes recovered and cryopreserved. Secondary measures of outcome: 1. #Days of ovarian stimulation to GnRH agonist trigger. 2. Peak serum estradiol level on day of GnRH agonist trigger. 3. Number of follicles \>15 mm average diameter on day of GnRH agonist trigger.
In April 2011, the United States Food and Drug Administration (FDA) approved the oral drug abiraterone acetate (Zytiga ®) in combination with prednisone (a steroid) to treat patients with metastatic castration-resistant prostate cancer who have received prior docetaxel (chemotherapy). In December 2012, the FDA approved Zytiga ® in combination with prednisone to treat patients with metastatic castration-resistant prostate cancer who have not received prior chemotherapy. Degarelix (Firmagon ®), a testosterone lowering agent given as a monthly injection, is FDA approved for the treatment of patients with advanced prostate cancer. The purpose of this study is to evaluate abiraterone acetate and prednisone in combination with degarelix as a possible treatment for PSA recurrent prostate cancer as compared to abiraterone acetate alone and degarelix alone. This will be the first time these drugs will be used together.
The purpose of this study is to determine if utilizing GnRH antagonists versus agonist long protocol during controlled ovarian stimulation (COH) with human-derived gonadotropins for assisted reproduction affects IVF outcome, peak estradiol level, and duration of stimulation.
MiRNAs are single-stranded small non-coding RNAs that act on specific mRNAs to regulate the gene expression. Studies have suggested that miRNAs influence cellular activities in the uterus, including cell differentiation and embryo implantation. In assisted reproductive cycles, controlled ovarian stimulation (COS) results in supraphysiological steroid levels and is associated with very low luteinizing hormone concentration during the luteal phase, the peri-implantation and implantation period. Luteal phase support, administration of medication aimed at supporting the implantation process, has been a routine practice in in vitro fertilization (IVF) clinics. Luteal phase support with steroid hormone has been found to improve pregnancy rates when human menopausal gonadotropins were used in conjunction with GnRH agonists for ovarian stimulation and IVF. Reports on effect of steroid supplementation in GnRH antagonist protocols are limited. The proposed project is an extension of our previous study on Endometrial Luteal Phase Characteristics and Luteal Phase Support in Controlled Ovarian Hyperstimulation Protocols with Gonadotropin Releasing Hormone Antagonists. The significance of this study is based on the importance of luteal phase endometrial after COS for the process of implantation. The availability of oocycte donors in assisted reproduction technology programs offers a unique opportunity to study the impact of different stimulation protocols on the quality of the luteal phase. In addition, the oocyte donor model may allow us to evaluate the impact of different luteal support protocols directly on the endometrial preparation by histological as well as biochemical markers. Study design: Study subjects underwent ovarian stimulation according to a gonadotropin/GnRH antagonist protocol. All donors had a baseline measurement of serum follicle stimulating hormone (FSH) and estradiol levels on the second day of their menstrual cycles. Provided serum FSH levels were less than 10mIU/ml and E2 levels were less than 60pg/ml, ovarian stimulation was initiated with recombinant FSH. The daily dose was adjusted according to follicular development by serial transvaginal ultrasound and serum E2 response. A daily evening dose of ganirelix acetate was initiated on the 6th day of stimulation and continued through the day of human chorionic gonadotropin administration. When at least three follicles reached a mean diameter of 18mm, ovulation was triggered with a single dose of Human chorionic gonadotropin (hCG). Sonographically guided transvaginal oocyte retrieval was performed 34-36 hours after the hCG administration. Thirty endometrial biopsies from oocyte donors on their COS cycles will be used for the study. Study subjects have been randomized into 4 groups. Grp 1: day of retrieval, did not receive any luteal-phase support, which serves as base line; grp2: 3, 5 and 10 days after retrieval with no luteal phase support, which serves as control; grp3: 3, 5 and 10 days after retrieval, luteal phase support with progesterone in the form of vaginal suppositories starting from the day after retrieval; grp4: daily oral dose of 2 mg 17β-estradiol in addition to the micronized progesterone. Immediately after the endometrial biopsy all specimens were stored in liquid nitrogen tanks at -196°C. Total RNA will be isolated and microarray will be performed using an Illumina miRNA expression panel. Array results will be compiled and analyzed focusing on the following aspects: the target genes of prominent miRNAs, miRNA profile in relation to target gene pathways; miRNA expression profile in relation to endometrial dating and status; effect of luteal phase support on miRNA expression after ovarian stimulation. Minimum of 3 miRNA arrays will be run for each sample for the purpose of statistical analysis. A total of 30 arrays will be needed for all samples from all groups. In this study, the investigators pose three questions: 1) How many and what types of miRNAs are in the endometrium during ovarian stimulation? This is to identify miRNAs and associated target genes that are relevant for endometrium receptivity; 2) Do levels of miRNA expression change during the luteal phase, or during the window of implantation? This is to examine the dynamics of miRNAs that are associated with remodeling process of endometrium; and 3) Do luteal phase support alter miRNA expression in the luteal phase? This is to investigate the steroid effect on miRNA regulation. The investigators hypothesize that many critical genes related to implantation are regulated by miRNAs. This research effort will potentially advance our knowledge of endometrial characteristics after COS and the impact of sex steroid supplementation. Overall the study should help better understand the genetic control of implantation. Completion of this study may also provide measurable scientific evidence and useful information for the management of IVF cycles.
26% of all ART cycles performed in the USA in 2003 (CDC data) are frozen embryo transfers (FET) and transfer of embryos resulting from egg donation (ED) to recipients. The typical protocol used to prepare a recipient for ET involves GnRH agonist (Lupron, Tap Pharmaceuticals) to down regulate the patient. A GnRH antagonist, such as Cetrotide (EMD Serono), is comparable to GnRH agonist and FDA approved to prevent spontaneous ovulation with ART treatment, and its usage decreases significantly the number of injections that the patient receives with treatment. The working hypothesis for this study is that the GnRH antagonist (Cetrotide) can be used instead of an agonist to achieve effective down regulation in FET and ED cycles. Presumably, patients will prefer Cetrotide over Lupron because of the markedly fewer injections required.
Ovulation induction (OI) using gonadotropins is one of the most widely prescribed treatments of infertility. One common problem encountered while attempting OI using gonadotropins is premature ovulation. The purpose of this study is to examine the effect of a single injection of a medication, called ganirelix, to prevent premature ovulation. Patients will be divided into two groups. In the first group, gonadotropins will be used to stimulate the ovaries. In the second group gonadotropins will be used in addition to a single injection of ganirelix, a gonadotropin releasing hormone (GnRH) antagonist. Pregnancy rates will be compared between groups.
In couples with infertility secondary to Diminished Ovarian Reserve, the investigators hypothesize that a delayed start (7 day) to ovarian stimulation with an GnRH antagonist (Ganirelix) will improve oocyte maturation and quality, and improve pregnancy outcomes.
This pilot study aims to address whether the prophylactic use of Cetrorelix Acetate after a long gonadotropin-releasing hormone (GnRH) agonist protocol post-hCG (human chorionic gonadotropin) administration can significantly reduce the incidence of OHSS in oocyte donors.
This study will examine whether the drug cetrorelex acetate (Cetrotide\[Registed Trademark\]) can protect ovarian function in women undergoing chemotherapy. Some cancer treatments are known to cause a change in women's periods or to cause menstruation to stop completely, so that they cannot become pregnant. Cetrorelex acetate has been used for many years to lower hormone levels and stop periods in patients undergoing in vitro fertilization treatments. This study will see if making the ovaries inactive may protect them from being affected by certain cancer drugs, and thus preserve fertility. Women up to age 21who have begun menstruating, who have their uterus and at least one functioning ovary, and who are undergoing chemotherapy with cyclophosphamide, busulfan, nitrogen mustard or L-phenalanin mustard may be eligible for this study. Participants undergo the following procedures during this 24-month study: Baseline evaluation * Medical history, physical examination and blood and urine tests * Questionnaire about quality of life, menstrual periods, vaginal bleeding and desire for future fertility * 3D ultrasound of abdomen * DEXA scan to evaluate bone density Assignment to treatment with: * Lo ovral (contraceptive pill to prevent pregnancy and control menstrual periods) alone, or * Lo ovral and the study drug cetrorelex acetate, given as an injection under the skin once a day for six menstrual cycles Evaluations * Transvaginal 3D ultrasound to monitor changes in the ovary - after 6 months of cetrorelex acetate injections * DEXA scan - after 6 months of cetrorelex acetate injections * Blood tests for safety monitoring, pregnancy testing, endocrine tests and research uses - every 3 months during first year, every 6 months during second year * Questionnaire to monitor changes and quality of life - every 3 months during first year, every 6 months during second year.
This research study involves the use of the drugs Letrozole, GnRH, and NAL-GLU GnRH antagonist. Letrozole is a drug that is approved by the U.S. Food and Drug Administration (FDA) for use in breast cancer treatment that has been found to block the formation of estrogen. The NAL-GLU GnRH antagonist is a drug that temporarily blocks the action of GnRH. GnRH is a hormone that the body makes that stimulates other hormones that then control the function of the ovary. The purpose is to study the effects of the administration of letrozole in women with GnRH deficiency at the same time that they receive gonadotropin-releasing hormone (GnRH). In addition, administration of letrozole and NAL-GLU GnRH antagonist in healthy women with normal menstrual cycles will be done to evaluate the role of estrogen in the control of the hormone FSH, or Follicle Stimulating Hormone, in the female reproductive cycle. A better understanding of FSH control may help in the development of new treatments for women with difficulty conceiving.
To compare the incidence of ovarian hyperstimulation syndrome (OHSS) and implantation rate between high responder patients using Gonadotropin releasing GnRH) agonist or human chorionic gonadotropin (hCG) to trigger final oocyte maturation.
