Trial overview
This clinical trial is a Phase 2 study of VIPOGLANSTAT in women with endometriosis.[1] It is an interventional study, which means researchers are giving study treatment and then measuring the results.[1]
The trial is designed to investigate the efficacy and safety of VIPOGLANSTAT for endometriosis-related pain.[1] The brief summary says the study aims to evaluate VIPOGLANSTAT on endometriosis-related NMPP.[1]
Who is being studied
The target population is women with endometriosis and endometriosis-related pain.[1] The trial data does not list more detailed eligibility rules, so the main group to know about is women affected by this condition.[1]
Endometriosis-related pain is the main condition being studied in this trial.[1] The study focuses on people who have pain outside menstrual days as part of their symptoms.[1]
What the trial measures
The main result, called the primary outcome, is the proportion of participants who have at least a 2.0-point or at least 30% reduction in their mean worst pain score, without increased opioid rescue medication use, during non-menstrual days from baseline to month 4.[1]
In simple terms, the researchers want to know how many participants get a clear drop in their worst pain and do not need more extra pain medicine.[1] The pain scale used is the NMPP NRS score, which is a number-based pain rating scale.[1]
The trial also looks at pain during non-menstrual days, which are days when the participant is not having a period.[1] This helps the researchers understand whether the treatment may improve pain beyond menstrual symptoms alone.[1]
Study design and treatment groups
The trial includes VIPOGLANSTAT capsules and a placebo that looks the same.[1] A placebo is an inactive look-alike capsule used for comparison so researchers can judge whether changes are due to the study treatment.[1]
The source data also mentions GS-248 and a placebo formulation for GS-248, but it does not provide further details about the role of these groups.[1] Because the source is limited, the clearest confirmed focus is the comparison of VIPOGLANSTAT with matching placebo capsules.[1]
Trial status and size
The trial status is Authorised, meaning it has been approved to proceed.[1] The planned enrollment is 300 participants.[1]
This size suggests the study is designed to collect enough information to better understand whether VIPOGLANSTAT may help with endometriosis-related pain in this patient group.[1] The trial is focused on a patient-centered outcome: meaningful pain improvement without more rescue opioid use.[1]
