ObsEva SA presents posters at the ACOG Annual Clinical and Scientific Virtual Meeting April 30 – May 2, 2021
GENEVA, Switzerland and BOSTON, MA – April 30, 2021 – ObsEva SA (NASDAQ: OBSV / SIX: OBSN) a biopharmaceutical company developing and commercializing novel therapies to improve women’s reproductive health, today announced the presentation of five e-Posters on linzagolix in the treatment of uterine fibroids at the American College of Obstetricians and Gynecologists (ACOG) Annual Clinical and Scientific Meeting (ACSM), which will take place virtually from April 30 to May 2, 2021.
The data presented further substantiate the best-in-class potential of linzagolix for the treatment of heavy menstrual bleeding (HMB) due to uterine fibroids addressing both key efficacy and safety parameters from the PRIMROSE Phase 3 program.
The posters being presented, along with lead authors and key conclusions are:
Poster #196:
Effects of the oral GnRH antagonist linzagolix on uterine and fibroid volume in two Phase 3 trials
Lead author: Jacques Donnez, MD, PhD; Professor, Société de Recherche pour l’Infertilité (SRI), Brussels and Catholic University of Louvain, Belgium
Key Conclusions: The 200 mg dose of linzagolix without hormonal add-back therapy (ABT) was the only dose to show consistent substantial and significant reductions in uterine and fibroid volumes. Linzagolix is the only GnRH antagonist with a high-dose non-ABT option with the potential for short-term use for reduction of uterine and fibroid volume.
Poster #231:
Impact of linzagolix on pain in patients with fibroid-related heavy menstrual bleeding: results of two Phase 3 trials
Lead author: Ayman Al-Hendy, MD, PhD; Professor, Department of Obstetrics and Gynecology, University of Chicago
Key Conclusions: Linzagolix 100 and 200 mg, with and without ABT, consistently improved pain in women with fibroid-associated HMB. Pain reduction in the treatment groups was achieved after 12 weeks and was maintained up to 52 weeks. By 12 weeks following termination of treatment, pain scores had increased but had not reached baseline levels.
Poster #2962:
Impact of linzagolix treatment on anemia in women with uterine fibroid related heavy menstrual bleeding: results of two Phase 3 clinical trials
Lead author: William Catherino, MD, PhD; Professor, Department of Gynecologic Surgery and Obstetrics, Uniformed Services University of the Health Sciences
Key Conclusions: High and low linzagolix doses with and without ABT improved hemoglobin and ferritin levels in anemic women with uterine fibroids. In the 12-week follow-up period hemoglobin levels decreased but did not return to baseline levels.
Poster #194:
Safety of linzagolix in the treatment of women with uterine fibroids: Results from two Phase 3 clinical trials
Lead author: Hugh Taylor, MD; Professor, Department of Obstetrics, Gynecology and Reproductive Sciences, Yale School of Medicine
Key Conclusions: Overall treatment emergent adverse event (TEAE) rates at 24 weeks were similar to placebo for the linzagolix 100 mg and 200 mg with ABT regimens. Lumbar spine bone mineral density (BMD) z-scores indicated no change in risk categories. TEAE rates at Week 24 and BMD up to 52 weeks support the potential for long term use of linzagolix 100 mg and 200 mg with ABT.
Poster #1868:
Impact of linzagolix on events of depression and other mood disorders in women with uterine fibroids
Lead author: Robert Taylor, MD, PhD; Professor, Obstetrics and Gynecology, University at Buffalo
Key Conclusions: In the Phase 3 uterine fibroids trials of linzagolix, the incidence of depression and other mood disorder adverse events was low and revealed no consistent drug-related pattern.
All ePosters will be displayed on the ACOG Annual Meeting virtual platform in gallery view with search features by title, topic, and category. Each ePoster will have a dedicated page that will include a 5-minute prerecorded ePoster preview.
About Uterine Fibroids
Uterine fibroids are common benign tumors of the muscular tissue of the uterus. Uterine fibroids affect women of childbearing age and can vary in size from undetectable to large bulky masses. Few long-term medical treatments are available, and as a result, approximately 300,000 hysterectomies are performed for uterine fibroids every year in the US. The symptoms of uterine fibroids are wide-ranging and include heavy menstrual bleeding, anemia, pelvic pressure and bloating, urinary frequency and pain that can be extremely debilitating with a significant impact on quality of life. These symptoms can also have an impact on mental health, creating the additional burden of anxiety and distress.
