Repros Reports Topline Positive Clinical Data After Two 18 Week Courses of Proellex® Delivered Orally and Vaginally for the Treatment of Uterine Fibroids
- Primary endpoint of induction of amenorrhea met for both pooled oral and vaginal delivery compared to placebo, p < 0.0001 and p=0.0071, respectively
- Statistically significant reduction in fibroid size from baseline achieved by the combined active arms for the pooled oral dosage form compared to placebo, p=0.0004
- Statistically significant improvement in Uterine Fibroid Symptom Severity Score (UFSQOL) achieved for the pooled oral dosage form compared to placebo, p=0.0211
- On the basis of a comparison of oral and vaginal delivery systems, the Company will propose the oral route of administration for Phase 3 development
- The Company plans to submit a request to the
FDAbefore the end of 2016 to discuss the Phase 3 program
Amenorrhea, cessation of menses, is known to occur when a sufficiently high plasma concentration of Proellex® is achieved. Subjects received 18 weeks of blinded treatment and were then withdrawn from the study medication to allow for menses. After menses occurred, a second 18 week course of treatment ensued. The study treatment assignments remained blinded to the subjects, physicians and those managing the study and data.
The incidence of amenorrhea in active treatment groups consistently showed a statistically significantly difference from the rate in placebo-treated subjects with both routes of administration. At the end of the second course of treatment (36 weeks total active treatment, or Last Observation Carried Forward, LOCF), 92.9% of oral Proellex®-treated subjects achieved amenorrhea, while only 50% of vaginally treated subjects stopped menses. The oral dosage form provided for consistent suppression of menses with evidence of a dose response. Furthermore, among those women who completed the second 18 week course of oral drug administration, 100% of the women at the 12 mg dose exhibited amenorrhea, whereas 88.9% of women on the 6 mg dose achieved amenorrhea.
Along with changes in menstrual patterns, fibroid size, measured by MRI, was reduced in volume. Fibroid volume decreased in the oral Proellex®-treated arms by a median of 42.0% (LOCF) and was statistically different from the change from baseline volume in the placebo subjects (0%, p = 0.0004). For women who completed the two 18 week courses of treatment, fibroid size reduction for the 12 mg oral and 6 mg oral doses was 58.2% and 32.9%, respectively, providing some evidence of a dose response effect.
