7. desember 2021 oppdatert av: MedImmune LLC

A Phase 3 Study of MEDI-524 (Motavizumab), an Enhanced Potency Humanized Respiratory Syncytial Virus (RSV) Monoclonal Antibody, for the Prevention of RSV Disease Among Native American Infants in the Southwestern United States

MI-CP117 was a Phase 3, randomized, double-blind, placebo-controlled trial designed to determine if motavizumab is more effective than placebo in reducing RSV hospitalization in otherwise healthy Native American Infants in the Southwestern United States during their first RSV season.

Detaljert beskrivelse

MI-CP117 was a Phase 3, randomized, double-blind, placebo-controlled trial designed to determine if motavizumab is more effective than placebo in reducing RSV hospitalization in otherwise healthy Native American infants during their first RSV season.

Participants were randomized in a 2:1 ratio to receive either 15 mg/kg motavizumab or placebo by intramuscular (IM) injection every 30 days during the RSV season for a maximum of 5 injections.

During their first RSV season, participants were evaluated monthly just prior to each injection of study drug for adverse events (AEs) (including medically attended otitis media), with a final post-dosing follow up evaluation at Study Day 150. During Seasons 1, 2, and 3, blood was to be collected prior to the first and last dose of study drug for serum chemistry evaluations, motavizumab serum concentrations, and anti-motavizumab antibodies. Efficacy and safety outcomes were examined through Study Day 150 and wheezing outcomes were evaluated from the time of randomization until the third birthday.

Tiltaksbeskrivelse
Tidsramme
Number of Participants With Respiratory Syncytial Virus (RSV) Hospitalization
Tidsramme: From study Day 0 through study Day 150
An RSV hospitalization is defined as either 1) a respiratory hospitalization with a positive central real-time reverse transcription polymerase chain reaction (RT-PCR) RSV test collected within 3 days of hospitalization or 2) new onset of lower respiratory symptoms in an already hospitalized child, with an objective measure of worsening respiratory status and positive RSV test.

Tiltaksbeskrivelse
Tidsramme
Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)
Tidsramme: From study Day 0 through study Day 150
An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event is any AE that resulted in death, life threatening, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, is a congenital anomaly/birth defect in offspring of a study participant, is an important medical event that may jeopardize the participant or may require medical intervention. The TEAEs are defined as events present at baseline that worsened in intensity after administration of study drug or events absent at baseline that emerged after administration of study drug.
From study Day 0 through study Day 150
Number of Participants With RSV Outpatient Medically Attended Lower Respiratory Illness (MA LRI)
Tidsramme: From study Day 0 through study Day 150
The RSV outpatient MA LRI was defined as an outpatient medically attended event designated as a lower respiratory illness with a positive RT-PCR RSV test. An LRI event is one that has a medical diagnosis of bronchiolitis or pneumonia. In the absence of such a medical diagnosis, the occurrence of LRI events was determined by the principal investigator after review of the medical record and considering the presence of cough, retractions, rhonchi, wheezing, crackles, or rales, associated with symptoms (by history or clinical findings) of coryza, fever, or apnoea.
From study Day 0 through study Day 150
Number of Participants With Medically Attended-Otitis Media (MA-OM) Events
Tidsramme: From study Day 0 through study Day 150
Otitis media (OM) was recorded as the diagnosis if the following terms were used by the medical care provider: acute OM, acute tympanic membrane (TM) perforation, bulging TM, red TM with fever, OM with effusion, or middle ear effusion. A new episode was defined as a physician-diagnosed OM in either ear after a normal middle ear exam of the ear in question or an episode of acute OM greater than or equal to 21 days after resolution of the previous episode. A diagnosis of persistent middle ear effusion was not recorded as a new OM event.
From study Day 0 through study Day 150
Number of Participants With Frequency of MA-OM Events
Tidsramme: From study Day 0 through study Day 150
Otitis media was recorded as the diagnosis if the following terms were used by the medical care provider: acute OM, acute TM perforation, bulging TM, red TM with fever, OM with effusion, or middle ear effusion. A new episode was defined as a physician-diagnosed OM in either ear after a normal middle ear exam of the ear in question or an episode of acute OM greater than or equal to 21 days after resolution of the previous episode. A diagnosis of persistent middle ear effusion was not recorded as a new OM event. Number of participants with frequency of MA-OM events (either 0, 1, 2, 3, or greater than [>] 3) are reported.
From study Day 0 through study Day 150
Number of Participants With Medically Attended Wheezing Episodes
Tidsramme: From first year through 3 years
Wheezing events were included in the analysis of medically-attended wheezing, if the medical care provider documented wheezing in the medical record or records as a discharge diagnosis any of asthma, bronchiolitis, wheezing, or reactive airway disease. A new wheezing episode was recorded as one that occurred >2 weeks after the diagnosis of the previous episode and the medical opinion was that the wheezing does not represent a persistence of the previous episode. Number of participants with greater than or equal to (>=) 1 MA wheezing events and >= 3 MA wheezing events occurring from first through 3 years of age are reported.
From first year through 3 years
Number of Participants With Serious Early Childhood Wheezing Episodes
Tidsramme: From first year through 3 years
Serious early childhood wheezing (SECW) was defined as: three or more medically attended wheezing events over a 12 month period occurring any time from the first through the third birthday, or a need for one or more courses of systemic steroids for a treatment of a medically attended wheezing event from the first through the third birthday, or a need for asthma-controller medication over a 12 month period for at least 3 consecutive months (>= 90 days) or 5 cumulative months (>= 150 days) any time from the first through the third birthday, or at least one inpatient wheezing event from the first through the third birthday.
From first year through 3 years
Number of Participants With Frequency of Medically Attended Wheezing Events
Tidsramme: Study Day 0 through 3 years
Wheezing events were included in the analysis of medically-attended wheezing, if the medical care provider documented wheezing in the medical record or records as a discharge diagnosis any of asthma, bronchiolitis, wheezing, or reactive airway disease. A new wheezing episode was recorded as one that occurred >2 weeks after the diagnosis of the previous episode and the medical opinion is that the wheezing does not represent a persistence of the previous episode. Number of participants with frequency of MA wheezing events (either 0, 1, 2, 3, 4, or greater than or equal to [>=] 5) are reported.
