Asoprisnil (J867): a selective progesterone receptor modulator for gynecological therapy
Steroids 2003 Nov;68(10-13):1019-32.PMID:14667995DOI:10.1016/j.steroids.2003.09.008.
Asoprisnil is a novel selective steroid receptor modulator that shows unique pharmacodynamic effects in animal models and humans. Asoprisnil, its major metabolite J912, and structurally related compounds represent a new class of progesterone receptor (PR) ligands that exhibit partial agonist and antagonist activities in vivo. Asoprisnil demonstrates a high degree of receptor and tissue selectivity, with high-binding affinity for PR, moderate affinity for glucocorticoid receptor (GR), low affinity for androgen receptor (AR), and no binding affinity for estrogen or mineralocorticoid receptors. In the rabbit endometrium, both Asoprisnil and J912 induce partial agonist and antagonist effects. Asoprisnil induces mucification of the guinea pig vagina and has pronounced anti-uterotrophic effects in normal and ovariectomized guinea pigs. Unlike antiprogestins, Asoprisnil shows only marginal labor-inducing activity during mid-pregnancy and is completely ineffective in inducing preterm parturition in the guinea pig. Asoprisnil exhibits only marginal antiglucocorticoid activity in transactivation in vitro assays and animal models. In male rats, Asoprisnil showed weak androgenic and anti-androgenic properties. In toxicological studies in female cynomolgus monkeys, Asoprisnil treatment abolished menstrual cyclicity and endometrial atrophy. Early clinical studies of Asoprisnil in normal volunteers demonstrated a dose-dependent suppression of menstruation irrespective of the effects on ovulation, with no change in basal estrogen concentrations and no antiglucocorticoid effects. Unlike progestins, Asoprisnil does not induce breakthrough bleeding. With favorable safety and tolerability profiles thus far, Asoprisnil appears promising as a novel treatment of gynecological disorders, such as uterine fibroids and endometriosis.
Selective Progesterone Receptor Modulators-Mechanisms and Therapeutic Utility
Endocr Rev 2020 Oct 1;41(5):bnaa012.PMID:32365199DOI:10.1210/endrev/bnaa012.
Selective progesterone receptor modulators (SPRMs) are a new class of compounds developed to target the progesterone receptor (PR) with a mix of agonist and antagonist properties. These compounds have been introduced for the treatment of several gynecological conditions based on the critical role of progesterone in reproduction and reproductive tissues. In patients with uterine fibroids, mifepristone and ulipristal acetate have consistently demonstrated efficacy, and vilaprisan is currently under investigation, while studies of Asoprisnil and telapristone were halted for safety concerns. Mifepristone demonstrated utility for the management of endometriosis, while data are limited regarding the efficacy of Asoprisnil, ulipristal acetate, telapristone, and vilaprisan for this condition. Currently, none of the SPRMs have shown therapeutic success in treating endometrial cancer. Multiple SPRMs have been assessed for efficacy in treating PR-positive recurrent breast cancer, with in vivo studies suggesting a benefit of mifepristone, and multiple in vitro models suggesting the efficacy of ulipristal acetate and telapristone. Mifepristone, ulipristal acetate, vilaprisan, and Asoprisnil effectively treated heavy menstrual bleeding (HBM) in patients with uterine fibroids, but limited data exist regarding the efficacy of SPRMs for HMB outside this context. A notable class effect of SPRMs are benign, PR modulator-associated endometrial changes (PAECs) due to the actions of the compounds on the endometrium. Both mifepristone and ulipristal acetate are effective for emergency contraception, and mifepristone was approved by the US Food and Drug Administration (FDA) in 2012 for the treatment of Cushing's syndrome due to its additional antiglucocorticoid effect. Based on current evidence, SPRMs show considerable promise for treatment of several gynecologic conditions.
Therapeutic potential for the selective progesterone receptor modulator Asoprisnil in the treatment of leiomyomata
Semin Reprod Med 2004 May;22(2):113-9.PMID:15164306DOI:10.1055/s-2004-828617.
Asoprisnil is a novel selective progesterone receptor modulator that exhibits partial agonist and antagonist activities in animals and humans. It demonstrates a high degree of progesterone receptor specificity and tissue selectivity. Although Asoprisnil at high doses exhibited some antiglucocorticoid activity in animal models, no antiglucocorticoid effects were observed at therapeutic doses in humans. In male rats, Asoprisnil showed mixed androgenic and antiandrogenic properties. Unlike antiprogestins, Asoprisnil at high doses exhibited only marginal labor-inducing activity in guinea pigs during midpregnancy and was completely ineffective in inducing preterm parturition. In nonhuman primates, Asoprisnil completely eliminated menstrual cyclicity and induced endometrial atrophy. Early clinical studies of Asoprisnil in healthy volunteers demonstrated a dose-dependent suppression of menstruation, irrespective of the effects on ovulation, with no change in basal estrogen concentrations and no breakthrough bleeding. Phase 2 studies in subjects with uterine fibroids demonstrated that Asoprisnil induced amenorrhea and reduced the volume of the dominant leiomyoma in a dose-dependent manner without altered basal estrogen and with virtually no clinical symptoms of estrogen deprivation. Asoprisnil seems to exhibit a direct inhibitory effect on both the endometrium and leiomyoma. In all studies to date, Asoprisnil has maintained a favorable safety and tolerability profile. Thus, Asoprisnil has the potential to target the major clinical symptoms of leiomyomata related to both menorrhagia and the size of the tumors and may, therefore, reduce or eliminate the need for surgery.
Preoperative medical therapy before surgery for uterine fibroids
Cochrane Database Syst Rev 2017 Nov 15;11(11):CD000547.PMID:29139105DOI:10.1002/14651858.CD000547.pub2.
Background: Uterine fibroids occur in up to 40% of women aged over 35 years. Some are asymptomatic, but up to 50% cause symptoms that warrant therapy. Symptoms include anaemia caused by heavy menstrual bleeding, pelvic pain, dysmenorrhoea, infertility and low quality of life. Surgery is the first choice of treatment. In recent years, medical therapies have been used before surgery to improve intraoperative and postoperative outcomes. However, such therapies tend to be expensive.Fibroid growth is stimulated by oestrogen. Gonadotropin-hormone releasing analogues (GnRHa) induce a state of hypo-oestrogenism that shrinks fibroids , but has unacceptable side effects if used long-term. Other potential hormonal treatments, include progestins and selective progesterone-receptor modulators (SPRMs).This is an update of a Cochrane Review published in 2000 and 2001; the scope has been broadened to include all preoperative medical treatments. Objectives: To assess the effectiveness and safety of medical treatments prior to surgery for uterine fibroids. Search methods: We searched the Cochrane Gynaecology and Fertility Group specialised register, CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL in June 2017. We also searched trials registers (ClinicalTrials.com; WHO ICTRP), theses and dissertations and the grey literature, handsearched reference lists of retrieved articles and contacted pharmaceutical companies for additional trials. Selection criteria: We included randomised comparisons of medical therapy versus placebo, no treatment, or other medical therapy before surgery, myomectomy, hysterectomy or endometrial resection, for uterine fibroids. Data collection and analysis: We used standard methodological procedures expected by The Cochrane Collaboration. Main results: We included a total of 38 RCTs (3623 women); 19 studies compared GnRHa to no pretreatment (n = 19), placebo (n = 8), other medical pretreatments (progestin, SPRMs, selective oestrogen receptor modulators (SERMs), dopamine agonists, oestrogen receptor antagonists) (n = 7), and four compared SPRMs with placebo. Most results provided low-quality evidence due to limitations in study design (poor reporting of randomisation procedures, lack of blinding), imprecision and inconsistency. GnRHa versus no treatment or placebo GnRHa treatments were associated with reductions in both uterine (MD -175 mL, 95% CI -219.0 to -131.7; 13 studies; 858 participants; I² = 67%; low-quality evidence) and fibroid volume (heterogeneous studies, MD 5.7 mL to 155.4 mL), and increased preoperative haemoglobin (MD 0.88 g/dL, 95% CI 0.7 to 1.1; 10 studies; 834 participants; I² = 0%; moderate-quality evidence), at the expense of a greater likelihood of adverse events, particularly hot flushes (OR 7.68, 95% CI 4.6 to 13.0; 6 studies; 877 participants; I² = 46%; moderate-quality evidence).Duration of hysterectomy surgery was reduced among women who received GnRHa treatment (-9.59 minutes, 95% CI 15.9 to -3.28; 6 studies; 617 participants; I² = 57%; low-quality evidence) and there was less blood loss (heterogeneous studies, MD 25 mL to 148 mL), fewer blood transfusions (OR 0.54, 95% CI 0.3 to 1.0; 6 studies; 601 participants; I² = 0%; moderate-quality evidence), and fewer postoperative complications (OR 0.54, 95% CI 0.3 to 0.9; 7 studies; 772 participants; I² = 28%; low-quality evidence).GnRHa appeared to reduce intraoperative blood loss during myomectomy (MD 22 mL to 157 mL). There was no clear evidence of a difference among groups for other primary outcomes after myomectomy: duration of surgery (studies too heterogeneous for pooling), blood transfusions (OR 0.85, 95% CI 0.3 to 2.8; 4 studies; 121 participants; I² = 0%; low-quality evidence) or postoperative complications (OR 1.07, 95% CI 0.43 to 2.64; I² = 0%; 5 studies; 190 participants; low-quality evidence). No suitable data were available for analysis of preoperative bleeding. GnRHa versus other medical therapies GnRHa was associated with a greater reduction in uterine volume (-47% with GnRHa compared to -20% and -22% with 5 mg and 10 mg ulipristal acetate) but was more likely to cause hot flushes (OR 12.3, 95% CI 4.04 to 37.48; 5 studies; 183 participants; I² = 61%; low-quality evidence) compared with ulipristal acetate. There was no clear evidence of a difference in bleeding reduction (ulipristal acetate 5 mg: OR 0.71, 95% CI 0.3 to 1.7; 1 study; 199 participants; moderate-quality evidence; ulipristal acetate 10 mg: OR 0.39, 95% CI 0.1 to 1.1; 1 study; 203 participants; moderate-quality evidence) or haemoglobin levels (MD -0.2, 95% CI -0.6 to 0.2; 188 participants; moderate-quality evidence).There was no clear evidence of a difference in fibroid volume between GnRHa and cabergoline (MD 12.71 mL, 95% CI -5.9 to 31.3; 2 studies; 110 participants; I² = 0%; low-quality evidence).The included studies did not report usable data for any other primary outcomes. SPRMs versus placebo SPRMs (mifepristone, CDB-2914, ulipristal acetate and Asoprisnil) were associated with greater reductions in uterine or fibroid volume than placebo (studies too heterogeneous to pool) and increased preoperative haemoglobin levels (MD 0.93 g/dL, 0.5 to 1.4; 2 studies; 173 participants; I² = 0%; high-quality evidence). Ulipristal acetate and Asoprisnil were also associated with greater reductions in bleeding before surgery (ulipristal acetate 5 mg: OR 41.41, 95% CI 15.3 to 112.4; 1 study; 143 participants; low-quality evidence; ulipristal acetate 10 mg: OR 78.83, 95% CI 24.0 to 258.7; 1 study; 146 participants; low-quality evidence; Asoprisnil: MD -166.9 mL; 95% CI -277.6 to -56.2; 1 study; 22 participants; low-quality evidence). There was no evidence of differences in preoperative complications. No other primary outcomes were measured. Authors' conclusions: A rationale for the use of preoperative medical therapy before surgery for fibroids is to make surgery easier. There is clear evidence that preoperative GnRHa reduces uterine and fibroid volume, and increases preoperative haemoglobin levels, although GnRHa increases the incidence of hot flushes. During hysterectomy, blood loss, operation time and complication rates were also reduced. Evidence suggests that ulipristal acetate may offer similar advantages (reduced fibroid volume and fibroid-related bleeding and increased haemoglobin levels) although replication of these studies is advised before firm conclusions can be made. Future research should focus on cost-effectiveness and distinguish between groups of women with fibroids who would most benefit.
Discovery, chemistry, and reproductive pharmacology of Asoprisnil and related 11beta-benzaldoxime substituted selective progesterone receptor modulators (SPRMs)
Semin Reprod Med 2005 Feb;23(1):58-73.PMID:15714390DOI:10.1055/s-2005-864034.
Asoprisnil (J 867; benzaldehyde, 4-[(11beta, 17beta)-17-methoxy-17-(methoxymethyl)-3-oxoestra-4, 9-dien-11beta-yl]-, 1-oxime) is the prototype of a novel class 11beta-benzaldoxime-substituted selective progesterone receptor modulators (SPRMs) and the first-in-class SPRM to reach an advanced stage of clinical development for the treatment of uterine fibroids and endometriosis. This compound was selected in a drug discovery program aimed to identify progesterone receptor (PR) ligands with predominant agonist but also some antagonist activities. The screening program included a range of receptor binding studies and a hierarchy of in vivo tests. A series of 11beta-benzaldoxime-substituted steroidal compounds exhibiting mixed PR agonist/antagonist effects were synthesized and characterized. For inclusion in this class of compounds, two methods of synthesis were developed and optimized. The 11beta-benzaldoxime-substituted SPRMs showed high PR binding affinities, reduced glucocorticoid receptor affinities compared with the antiprogestin mifepristone, marginal androgen receptor binding affinities, and no binding to estrogen receptors. Animal tests in guinea pigs (luteolysis inhibition assay) and rabbits (McPhail test) constituted the secondary screening tests. A mosaic of progesterone agonist and antagonist effects were found in various models. The most agonistic compounds were selected for further evaluation in animal models with respect to labor induction and endometrial effects. Unlike progesterone antagonists, Asoprisnil and related compounds showed marginal effects on labor and parturition in guinea pigs. Proof-of-concept studies in nonhuman primates revealed endometrial antiproliferative effects of selected compounds, including Asoprisnil and J 1042, in the presence of amenorrhea and follicular phase estradiol concentrations. Asoprisnil was selected for further clinical development. It shows promising results in the treatment of uterine leiomyomata and endometriosis.
