Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built

Investigator standing0/100
No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

Zusammenfassung

This is a Phase 2/3 study evaluating the safety and efficacy of DM199 (rinvecalinase alfa) in treating participants with moderate stroke severity, who present within 24 hours of Acute Ischemic Stroke (AIS) onset due to small and medium vessel occlusions. This study focuses on participants with limited treatment options. Participants who have or will receive mechanical thrombectomy (MT) are not eligible for participation. Additionally, participants who have received fibrinolytics are excluded unless they experience a persistent neurological deficit of moderate severity six or more hours after fibrinolytic treatment. Participants considered for this trial should not be denied the use of standard of care (SoC) AIS therapies, such as fibrinolytics or MT, when appropriate. The double-blinded study will be randomized and placebo-controlled at up to approximately 100 sites.

This is a Phase 2/3 Adaptive Design, Randomized, Double-blind, Placebo-controlled Study to Evaluate the Safety and Efficacy of DM199 for the Treatment of Acute Ischemic Stroke (ReMEDy2 Trial). Participants with AIS will be randomized 1:1 to DM199 or placebo. DM199 will be administered as a single intravenous (IV) dose (0.5 μg/kg; not to exceed 50 μg) followed by subcutaneous (SC) doses at 2 hours (+10 hours) of the IV dose completion and then 2 times per week up to Day 21. The duration of each individual's participation in the study will be approximately 90 days from the time of initial treatment to completion of all study activities. A formal interim analysis will be conducted after 200 participants complete their Day 90 assessment in Part A. The purposes of this interim analysis are to assess safety, allow early stopping of the study for futility, or continuing the study with a revised final sample up to a maximum of 728 participants.

Life expectancy estimated at ≤1 year prior to enrollment. 13. Participant has clinical evidence of an active infection at the time of enrollment requiring parenteral treatment or hospitalization to monitor or manage the infection. NOTE: Treatment of uncomplicated infections with oral antibiotics would not be an exclusion (for example, the treatment of uncomplicated urinary tract infections or sinus infections with oral antibiotics would not be exclusionary). 14. Participant has known alpha 1-antitrypsin deficiency (α1-antitrypsin deficiency). 15. Participant is pregnant or nursing. NOTE: Participants who agree to stop nursing may be considered for inclusion at the discretion of the Investigator. 16. Participants of child-bearing potential must agree to use medically acceptable contraceptive measures to prevent pregnancy. All participants of childbearing potential (defined as sexually mature participants who have had menses within the preceding 24 months and have not undergone permanent sterilization methods such as hysterectomy, bilateral oophorectomy, bilateral salpingectomy, etc.) must have a negative serum pregnancy test performed locally at screening. Participants of childbearing potential must agree not to attempt to become pregnant or undergo in vitro fertilization. If participating in sexual activity that could lead to pregnancy, participants must use 2 reliable methods (1 per partner is acceptable) of contraception simultaneously while receiving protocol-specified medication and during the study follow-up period. Participants participating in sexual activity must agree to use, or for their partner to use highly effective birth control methods (those with a failure rate of less than 1% per year when used consistently and correctly) until they have completed the study (after the Day 90 visit). Such methods include: * Combined (estrogen and progesterone containing) hormonal oral, intravaginal, or transdermal contraception associated with the inhibition of ovulation * Progesterone-only oral, injectable, or implantable hormonal contraception associated with the inhibition of ovulation * Intrauterine device (IUD) * Intrauterine hormone-releasing system (IUS) * Bilateral tubal occlusion * Vasectomized partner * Sexual abstinence Participants who are not of reproductive potential (who have been postmenopausal for more than 24 consecutive months or have undergone hysterectomy, bilateral oophorectomy, bilateral salpingectomy, etc.) are not required to use contraception. Participants are prohibited from sperm donation. NOTE: A negative serum pregnancy test will be documented during screening if a participant is of child-bearing potential. 17. Participant is currently participating in or has participated in a study using an investigational device or drug or received an investigational drug or investigational use of a licensed drug within 30 days prior to screening. 18. Participant does not have sufficient venous access for infusion of study treatment or blood sampling. 19. Participant is unable or unwilling to comply with protocol requirements, including assessments, tests, and follow-up visits. 20. Participant has any other medical condition which in the opinion of the Investigator will make participation medically unsafe or interfere with the study results.
