Participant has signed, dated, and received a copy of the Institutional Review Board (IRB)/Independent Ethics Committee (IEC)-approved written informed consent form (ICF) for the LTE study.\n- 3. Contraceptive use by participants must be consistent with local regulations regarding the methods of contraception for those participating in clinical studies."}

Exclusion criteria

  • {"criterion_text":"- 1.\tAbnormal medical history, physical finding, or safety finding that in the opinion of the Investigator may obscure the study data or interfere with the participant’s safety.\n- 2.\tAny clinical laboratory test result outside of the reference ranges considered by the Investigator as clinically significant and that may obscure the study data or interfere with the participant’s safety.\n- 3.\tParticipant with a history or evidence of a clinically significant pulmonary condition (other than asthma), including significant restrictive findings on pulmonary function testing, chronic bronchitis, emphysema, bronchiectasis, pulmonary fibrosis, or any other related condition that may obscure the study data (e.g., gastroesophageal reflux and vocal cord paralysis/dysfunction).\n- 4.\tPregnant or breastfeeding or planning to become pregnant or breastfeed during the study or unwilling to use adequate birth control, if of reproductive potential and sexually active.\n- 5.\tParticipants with significant protocol deviations in VALIANT, assessed at the discretion of the Sponsor.\n- 6.\tParticipant is unreliable, incapable of adhering to the protocol and visit schedule according to the judgment of the Investigator or has any disorder that may compromise their ability to give informed consent."}

Endpoints

Primary endpoints

  • {"endpoint_text":"- To check if verekitug is safe, participants will be monitored for any side effects from the time the participant agrees to join the study until the participant completes the study. Participants will also have physical examinations, clinical laboratory assessments, vital sign measurements, and ECGs from the first LTE study visit, or last VALIANT study visit, until the participant completes the LTE study.","definition_or_measurement_approach":"Monitoring for adverse events from consent until study completion; physical examinations, clinical laboratory assessments, vital signs and ECGs performed from first LTE visit (or last VALIANT visit) until study completion."}

Secondary endpoints

  • {"endpoint_text":"- To check the effects of verekitug, the number of severe asthma flare-ups or attacks that require treatment with steroids over 60 weeks of treatment will be recorded.","definition_or_measurement_approach":"Count of severe asthma exacerbations requiring corticosteroid treatment recorded over 60 weeks of treatment."}
  • {"endpoint_text":"- The change in the following from the start of the LTE study up to Week 60 will be recorded: how much air the participant can forcefully exhale in 1 second; how much nitric oxide is in the exhaled air as a measure of airway inflammation; and how well the participant’s asthma is being managed via a scored questionnaire about asthma symptoms and treatment.","definition_or_measurement_approach":"Change from baseline to Week 60 in FEV1 (forced expiratory volume in 1 second), fractional exhaled nitric oxide (FeNO), and asthma control as measured by a scored questionnaire."}
  • {"endpoint_text":"- The amount of verekitug in the blood will be measured at each visit to see how the body processes verekitug. The blood will also be checked for antibodies against verekitug during the LTE study (from the first to last visit) to check for an immune response.","definition_or_measurement_approach":"Pharmacokinetic measurement: serum concentration of verekitug at each visit. Immunogenicity: assay for anti-drug antibodies measured from first to last visit."}
