Post-Market Safety of Laparoscopic Ultrasound-Guided Radiofrequency Ablation.

BACKGROUND AND OBJECTIVES: Postoperative safety outcomes with laparoscopic intra-abdominal ultrasound-guided radiofrequency ablation, as performed by gynecologic surgeons new to the procedure, were evaluated and compared to the premarket, pivotal study. Post-procedure feedback from surgeons was reported. METHODS: This was a post-market, prospective, single-arm analysis with 4 to 8 weeks follow-up among surgeons (n = 29) with varying levels of laparoscopic surgery experience participating in the ongoing, multinational Treatment Results of Uterine Sparing Technologies randomized clinical trial. Patients were premenopausal adult women (n = 110) desiring uterine-conserving treatment for symptomatic fibroids. During run-in, surgeons received proctored training. Following training, and after performing ≥ 2 procedures, surgeons provided self-assessment and feedback using a standardized form. RESULTS: Surgeons performed 105 procedures with 100 per-protocol patients. The average number of proctored cases per surgeon was 2.48. No acute (≤ 48 hours) serious adverse events occurred (0/101, 0.0%) compared with 2 acute serious adverse events in the premarket study (2/137, 1.46%). Both studies reported 1 near-term (∼30 days) serious adverse event (< 1% for both). In this study, the near-term complication was fever of unknown origin requiring hospitalization related to uterine entry/manipulation. This was categorized as probably device-related; the patient was treated with antibiotics and discharged. Twenty-six surgeons completed the evaluation form; none reported experiencing problems with the procedure. CONCLUSION: Minimally invasive gynecologic surgeons can learn laparoscopic intraabdominal ultrasound-guided radiofrequency ablation and perform it safely (in terms of acute and near-term serious adverse events) after ≥ 2 proctored cases. There were no significant differences in safety outcomes compared to the premarket, pivotal study.

Preimplantation genetic testing for aneuploidy versus morphology as selection criteria for single frozen-thawed embryo transfer in good-prognosis patients: a multicenter randomized clinical trial.

OBJECTIVE: To evaluate the benefit of next-generation sequencing (NGS)-based preimplantation genetic testing for aneuploidy (PGT-A) for embryo selection in frozen-thawed embryo transfer. DESIGN: Randomized controlled trial. SETTING: Not applicable. PATIENT(S): Women aged 25-40 years undergoing IVF with at least two blastocysts that could be biopsied. INTERVENTION(S): Randomization for single frozen-thawed embryo transfer with embryo selection based on PGT-A euploid status versus morphology. MAIN OUTCOME MEASURE(S): Ongoing pregnancy rate (OPR) at 20 weeks' gestation per embryo transfer. RESULT(S): A total of 661 women (average age 33.7 ± 3.6 years) were randomized to PGT-A (n = 330) or morphology alone (n = 331). The OPR was equivalent between the two arms, with no significant difference per embryo transfer (50% [137/274] vs. 46% [143/313]) or per intention to treat (ITT) at randomization (41.8% [138/330] vs. 43.5% [144/331]). Post hoc analysis of women aged 35-40 years showed a significant increase in OPR per embryo transfer (51% [62/122] vs. 37% [54/145]) but not per ITT. CONCLUSION(S): PGT-A did not improve overall pregnancy outcomes in all women, as analyzed per embryo transfer or per ITT. There was a significant increase in OPR per embryo transfer with the use of PGT-A in the subgroup of women aged 35-40 years who had two or more embryos that could be biopsied, but this was not significant when analyzed by ITT. CLINICAL TRIAL REGISTRATION NUMBER: NCT02268786.

Patient experience in a randomized trial of a weekly progesterone vaginal ring versus a daily progesterone gel for luteal support after in vitro fertilization.

OBJECTIVE: To assess patient experience and convenience of using progesterone vaginal ring (VR) versus vaginal gel for women requiring luteal phase support during in vitro fertilization (IVF). DESIGN: Post hoc analysis of a prospective, randomized, single-blind, multicenter, phase 3 clinical trial. SETTING: Twenty-two U.S. IVF centers. PATIENT(S): Women undergoing IVF (N = 1,297). INTERVENTION(S): Randomization to weekly VR or daily gel the day after egg retrieval for up to 10 weeks, with fresh embryo transfer IVF per site-specific procedures. MAIN OUTCOME MEASURE(S): Patient satisfaction questionnaire completed at final study visit. RESULT(S): In the women who were taking ≥1 dose of either VR (n = 647) or gel (n = 650), >97% reported that learning to use the formulation, remembering to take it at the correct time, and using it as prescribed was "easy" or "somewhat easy." More VR than gel users reported noninterference with daily activity (93.3% vs. 74.7%, P<.001), sexual comfort (80.3% vs. 67.8%, P<.001), and sexual desire (73.8% vs. 61.8%, P<.001), as well as not being bothered during sexual intercourse (66.9% vs. 39.2%, P<.001). More gel than VR users reported no difficulty with application (97.4% vs. 80.9%, P<.001). Among women who had previously used progesterone during IVF, more VR users than gel users preferred their currently assigned treatment to their previous treatment (91.4% vs. 83.0%, P=.03). CONCLUSION(S): Weekly progesterone VR and daily progesterone gel were easy to use, with limited impact on quality of life. Overall, the VR appeared to interfere less with daily life, social activities, and sexual activity although the gel was less difficult or stressful to apply. CLINICAL TRIAL REGISTRATION NUMBER: NCT00615251.

Examining the evidence: progesterone supplementation during fresh and frozen embryo transfer.

ART has evolved over time and frozen-thawed embryo transfer (FET) is now a frequently performed, successful option. During the last decade, cryopreservation techniques have received considerable interest, whereas interest in the priming and preparation of the endometrium prior to and after embryo transfer was more limited. The available evidence for the rationale and timing of progesterone supplementation as well as an understanding of the differences among progesterone formulations with respect to efficacy, optimum use, and patient preference is worth examining. A Summit was convened to review the literature on progesterone supplementation in ART and after FET and to provide guidance on the most clinically relevant issues. Utilizing an innovative consensus-building model to examine the evidence, Summit faculty drafted summit statements prior to the meeting, completed a literature search, and created a presentation based on this. At the conclusion of their discussion the faculty developed final summit statements, evaluating the strength of the evidence supporting each statement, and rating their level of support for each statement. The clinically relevant topic areas were the rationale for progesterone supplementation, timing and appropriate dosing, whether progesterone sérum levels reflect outcomes, and distinguishing among progesterone formulations with respect to efficacy, tolerability, and patient preference/satisfaction.

Progesterone vaginal ring versus vaginal gel for luteal support with in vitro fertilization: a randomized comparative study.

OBJECTIVE: To compare the efficacy and safety of luteal phase support in IVF with a progesterone (P) vaginal ring or gel (VR or VG). DESIGN: Prospective, randomized, single-blind, multicenter, phase III clinical trial (ClinicalTrials.gov identifier: NCT00615251). SETTING: Nineteen private and three academic high-volume U.S. IVF centers. PATIENT(S): One thousand two hundred ninety-seven infertile patients were randomized to a weekly P VR (n = 646) or a daily P 8% VG (n = 651). INTERVENTION(S): IVF was performed per site-specific protocols. The day after egg retrieval, patients were randomized and began VR or VG therapy, which continued for up to 10 weeks' gestation. MAIN OUTCOME MEASURE(S): Clinical pregnancy rates at 8 and 12 weeks of pregnancy; rates of biochemical pregnancy, live birth, spontaneous abortion, ectopic pregnancy, and cycle cancellation; and safety and tolerability were secondary measures. RESULT(S): Clinical pregnancy rates at 8 and 12 weeks were high and comparable between groups: 48.0% for VR and 47.2% for VG at week 8 and 46.4% (VR) and 45.2% (VG) at week 12. Live-birth rates were 45% (VR) and 43% (VG). Adverse event profiles were similar between groups. CONCLUSION(S): The weekly P VR provided similar pregnancy rates to the daily VG, with no major differences in safety.

Vaginal (Crinone 8%) gel vs. intramuscular progesterone in oil for luteal phase support in in vitro fertilization: a large prospective trial.

OBJECTIVE: To compare the efficacy of intravaginal and IMP for luteal phase support in IVF cycles. DESIGN: Prospective trial. SETTING: Tertiary care private practice. PATIENT(S): Women 25-44 years old with infertility necessitating treatment with IVF. From April 1, 2008-April 1, 2009, 511 consecutive patients were enrolled; 474 completed participation, and 37 were excluded for no autologous ET (freeze all, donor recipients, failed fertilization/cleavage). There were no demographic differences between the two treatment groups. INTERVENTION(S): Luteal phase support using either Crinone or P in oil starting 2 days following oocyte retrieval. MAIN OUTCOME MEASURE(S): Pregnancy and delivery rates stratified by patient age. RESULT(S): Overall, patients who received vaginal P had higher pregnancy (70.9% vs. 64.2%) and delivery (51.7% vs. 45.4%) rates than did patients who received IMP. Patients <35 who received vaginal P had significantly higher delivery rates (65.7% vs. 51.1%) than did patients who received IMP. There were no differences, regardless of age, in the rates of biochemical pregnancy, miscarriage, or ectopics. CONCLUSION(S): In younger patients undergoing IVF, support of the luteal phase with Crinone produces significantly higher pregnancy rates than does IMP. Crinone and IMP appear to be equally efficacious in the older patient.

Gynecologic use of Sepraspray Adhesion Barrier for reduction of adhesion development after laparoscopic myomectomy: a pilot study.

OBJECTIVE: To assess the safety and efficacy of Sepraspray Adhesion Barrier (a modified hyaluronic acid and carboxymethylcellulose powder) after laparoscopic surgery, in view of both the high efficacy of Seprafilm Adhesion Barrier in reducing postoperative adhesions after open surgical procedures and the difficulty with laparoscopic delivery. DESIGN: Multicenter, randomized, reviewer-blinded trial. SETTING: Reproductive endocrinology and infertility clinics. PATIENT(S): Women undergoing laparoscopic myomectomy for indications including infertility. INTERVENTION(S): Randomization to treatment with (n = 21) or without (n = 20) Sepraspray Adhesion Barrier. MAIN OUTCOME MEASURE(S): Postoperative adhesions development was assessed at early second-look laparoscopy. Adhesions were scored using the modified American Fertility Society scoring system. RESULT(S): Surgical procedure duration length was 99 versus 102 minutes in the control versus Sepraspray Adhesion Barrier groups, respectively, with the median number of fibroids removed being two in each group and corresponding fibroid weights of 134 ± 103 versus 113 ± 161 g, respectively. Adhesions scores increased in both the control and Sepraspray Adhesion Barrier groups, with larger although nonstatistically significant increases noted in control subjects when evaluating for the anterior uterus, the posterior uterus, and the entire uterus. CONCLUSION(S): Laparoscopic application of Sepraspray Adhesion Barrier after myomectomy in this pilot study was associated with a trend toward a reduction in postoperative adhesion development, as well as an encouraging safety profile. Further evaluation is warranted. CLINICAL TRIAL NUMBER: Sepraspray Adhesion Barrier #NCT00624930.

Recurrence of ovarian torsion in a multiple pregnancy: conservative management via transabdominal ultrasound-guided ovarian cyst aspiration.

OBJECTIVE: To report a case of recurrent ovarian torsion during a multiple-gestation pregnancy and successful treatment via transabdominal ultrasound-guided ovarian cyst aspiration. DESIGN: Case report and literature review. SETTING: Tertiary care fertility center. PATIENT(S): A 33-year-old gravida 2, para 1 woman with a history of ovarian torsion in a previous pregnancy, who presented with recurrent ovarian torsion in the 13th week of a multiple pregnancy. INTERVENTION(S): Ultrasound-guided transabdominal ovarian cyst aspiration and body repositioning to allow for spontaneous detorsion. MAIN OUTCOME MEASURE(S): Resolution of the ovarian torsion, as well as preservation of the pregnancy without surgical intervention. RESULT(S): After transabdominal ultrasound-guided cyst aspiration, ovarian detorsion was observed, accompanied by resolution of the patient's acute pain. The remainder of the patient's pregnancy was uncomplicated, culminating in the delivery of healthy infants. CONCLUSION(S): Conservative treatment of ovarian torsion via ultrasound-guided transabdominal cyst aspiration and body repositioning represents a reasonable alternative to surgical intervention in the pregnant patient.

An employer's experience with infertility coverage: a case study.

A case study of Southwest Airlines, a Fortune 500 company, demonstrates that a well-designed infertility coverage plan can control resource use. This successful model could be used by employers who wish to ensure that their employees have access to high-quality, cost-effective infertility services in a managed-care environment.

Effect of prolonged gonadotropin-releasing hormone agonist therapy on the outcome of in vitro fertilization-embryo transfer in patients with endometriosis.

OBJECTIVE: To evaluate the effect of a 3-month course of GnRH agonist administered immediately before IVF-ET in infertile patients with endometriosis. DESIGN: Prospective, randomized trial. SETTING: Three tertiary care assisted reproductive technology programs. PATIENT(S): IVF-ET candidates with surgically confirmed endometriosis. INTERVENTION(S): Twenty-five patients received three courses of a long-acting GnRH agonist, 3.75 mg i.m. every 28 days, followed by standard controlled ovarian hyperstimulation. Twenty-six patients received standard controlled ovarian hyperstimulation with mid-luteal phase GnRH agonist down-regulation or microdose flare regimens. MAIN OUTCOME MEASURE(S): Response to controlled ovarian hyperstimulation, ongoing pregnancy rates per cycle, group implantation rates, and implantation rate per embryo transfer procedure. RESULT(S): The extent of surgically confirmed endometriosis was greater in patients who received the long-acting GnRH regimen for 3 months before IVF-ET. The groups did not differ significantly in terms of dose or duration of gonadotropin stimulation, number of oocytes retrieved, fertilization rate, or number of embryos transferred. Patients who received the long-acting GnRH regimen had significantly higher ongoing pregnancy rates (80% vs. 53.85%) and a trend toward higher implantation rates (42.68% vs. 30.38%). CONCLUSION(S): Prolonged use of GnRH agonist before IVF-ET in patients with endometriosis resulted in significantly higher ongoing pregnancy rates than did standard controlled ovarian hyperstimulation regimens. No deleterious effect on ovarian response was observed.

Analysis of the cost effectiveness of recombinant versus urinary follicle-stimulating hormone in in vitro fertilization/intracytoplasmic sperm injection programs in the United States.

OBJECTIVE: To compare the cost effectiveness of recombinant human FSH (Gonal-F; Serono, Inc., Randolph, MA) and urinary FSH (Fertinex; Serono, Inc.) for ovarian stimulation during IVF with or without intracytoplasmic sperm injection for the treatment of infertility. DESIGN: Clinical decision analysis techniques (the Markov model) were used to model the direct medical costs per patient during assisted reproductive technology. MAIN OUTCOME MEASURE(S): Clinical and economic outcomes of two different ovarian stimulation protocols (recombinant human FSH or urinary FSH) during three treatment cycles were considered. RESULT(S): More ongoing pregnancies were achieved, with fewer stimulation cycles, after recombinant human FSH (Gonal-F) than after urinary FSH (Fertinex) (40,665 versus 37,890). In addition, recombinant human FSH was also found to be more cost effective per ongoing pregnancy. From a societal perspective, the mean cost per pregnancy was $40,688 for recombinant human FSH versus $47,096 for urinary FSH. From the insurers' perspective, the mean cost/pregnancy for recombinant human FSH was $28,481 versus $32,967 for urinary FSH. CONCLUSION(S): Recombinant human FSH (Gonal-F) is not only more efficient clinically than urinary FSH (Fertinex), but also more cost effective. This analysis illustrates the point that the economic effectiveness of a drug depends less on its acquisition costs and rather more on the clinical outcomes associated with its use.
