Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Clinical Resolution Among Who Received SHP640 or Placebo on Day 6Day 6Clinical resolution of adenoviral conjunctivitis was defined as the absence (score=0) of bulbar conjunctival injection and watery conjunctival discharge in the study eye. The study eye was defined based on participant's bulbar conjunctival redness and watery conjunctival discharge scores at baseline as well as his/her cell culture-immunofluorescence assay (CC-IFA) results at baseline. Bulbar conjunctival injection was assessed based on a 0 (Normal conjunctival vascular pattern)-4 (Markedly prominent, intense diffuse hyperemia) scale which used pictures from the validated bulbar redness (VBR) scale. Watery conjunctival discharge was assessed based on a 0-3 scale (0 - None and 3 - Severe: Abundant quantity of watery discharge observed in the lower conjunctival fornix and in the lower lid margin). Higher score represent worse symptoms for both scores. Data analysis was performed in SHP640 and placebo reporting groups only but not in PVP-I 0.6%.

Number of Participants With Clinical Resolution Among Who Received SHP640 or Placebo on Day 6

Clinical resolution of adenoviral conjunctivitis was defined as the absence (score=0) of bulbar conjunctival injection and watery conjunctival discharge in the study eye. The study eye was defined based on participant's bulbar conjunctival redness and watery conjunctival discharge scores at baseline as well as his/her cell culture-immunofluorescence assay (CC-IFA) results at baseline. Bulbar conjunctival injection was assessed based on a 0 (Normal conjunctival vascular pattern)-4 (Markedly prominent, intense diffuse hyperemia) scale which used pictures from the validated bulbar redness (VBR) scale. Watery conjunctival discharge was assessed based on a 0-3 scale (0 - None and 3 - Severe: Abundant quantity of watery discharge observed in the lower conjunctival fornix and in the lower lid margin). Higher score represent worse symptoms for both scores. Data analysis was performed in SHP640 and placebo reporting groups only but not in PVP-I 0.6%.

Time frame: Day 6

Population: Modified Intent to Treat (mITT) population consisted of a subset of the ITT population who received at least one dose of investigational product (IP) and had a positive CC-IFA adenovirus test at baseline in the study eye. Here, the number of participants analyzed refer to the participants evaluable for this outcome at specified time point.

Number of Participants With Clinical Resolution Among Who Received Povidone-Iodine (PVP-I) or Placebo on Day 6

Clinical resolution of adenoviral conjunctivitis was defined as the absence (score=0) of bulbar conjunctival injection and watery conjunctival discharge in the study eye. The study eye was defined based on participant's bulbar conjunctival redness and watery conjunctival discharge scores at baseline as well as his/her CC-IFA results at baseline. Bulbar conjunctival injection was assessed based on a 0 (Normal conjunctival vascular pattern)-4 (Markedly prominent, intense diffuse hyperemia) scale which used pictures from the validated bulbar redness (VBR) scale. Watery conjunctival discharge was assessed based on a 0-3 scale (0 - None and 3 - Severe: Abundant quantity of watery discharge observed in the lower conjunctival fornix and in the lower lid margin). Higher score represent worse symptoms for both scores. Data analysis was performed in PVP-I 0.6% and placebo reporting groups only but not in SHP640.

Time frame: Day 6

Population: mITT population consisted of a subset of the ITT population who received at least one dose of IP and had a positive CC-IFA adenovirus test at baseline in the study eye. Here, the number of participants analyzed refer to the participants evaluable for this outcome at specified time point.

Number of Participants With Expanded Clinical Resolution on Day 3, 6, 8 and 12/Early Termination (ET)

Expanded clinical resolution was defined as a global clinical score of 0, 1, or 2 with neither injection nor discharge having a score of 2. Global clinical score was the sum of bulbar conjunctival injection and watery conjunctival discharge. The study eye was defined based on participants bulbar conjunctival redness and watery conjunctival discharge scores at baseline as well as his/her CC-IFA results at baseline.

Time frame: Day 3, 6, 8 and 12/ET

Population: The study was terminated as the sponsor discontinued the SHP640 clinical development with reason unrelated to safety. Hence, for this outcome measure, the planned data collection and analysis was not performed.

Secondary

Number of Participants With Modified Clinical Resolution on Day 3, 6, 8 and 12/Early Termination (ET)

Modified clinical resolution was defined as a global clinical score of 0 or 1. Global clinical score was the sum of bulbar conjunctival injection and watery conjunctival discharge. The study eyewas defined based on participants bulbar conjunctival redness and watery conjunctival discharge scores at baseline as well as his/her CC-IFA results at baseline.

Time frame: Day 3, 6, 8 and 12/ET

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Event (SAEs) of SHP640

An Adverse Event (AE) was any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. A SAE was any untoward medical occurrence (whether considered to be related to investigational product or not) that at any dose: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital abnormality/birth defect, is an important medical event. Any AE that occured after the first dose of IP instillation was considered a TEAE.

Time frame: From start of the study up to Day 14

Population: Safety Population consisted of all participants who received at least one dose of IP.
