Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Pain on Movement (POM) on Day 5 of Treatment as Assessed by a 100 Millimeter (mm) Visual Analogue Scale (VAS)

    The investigator performed a movement of the ankle and the pain assessment was done by the participant using a 100 mm VAS by describing ankle pain on movement. The POM was registered by the participant by drawing a perpendicular line on the 100 mm VAS with anchors at 0 = no pain and 100 = extreme pain. Higher scores indicate a worse outcome. Change from Baseline in POM was calculated by subtracting the Baseline value from the Day 5 value.

    Baseline and Day 5

Secondary Outcomes (11)

  • Number of Participants With Severity of Adverse Events (AEs) Following Dosing With Study Medication

    up to 28 days following last administration of the study product (or last procedure)

  • Change From Baseline of POM on VAS on Day 3 and Day 8 of Treatment Assessed by 100 mm VAS

    Baseline and Days 3 and 8

  • Change From Baseline in Tenderness as Measured by Pressure Algometry on Days 3, 5 and 8

    Baseline and Days 3, 5 and 8

  • Changes From Baseline in Difference of Tenderness Between Affected Ankle and Contralateral Ankle Measured by Algometry on Days 3, 5 and 8

    Baseline and Days 3, 5 and 8

  • Change From Baseline in Ankle Joint Function (Karlsson Scoring Scale) on Days 3, 5 and 8

    Baseline and Days 3, 5 and 8

  • +6 more secondary outcomes

Study Arms (2)

Diclofenac diethylamine (DDEA) 2.32%/ Placebo gel

EXPERIMENTAL

Participants will receive 4 tubes, DDEA 2.32% gel and Placebo gel (2 each) and instructed to apply the gel 5 centimeter (cm) topically with the finger tips (for approximately 1 minute) on both sides of affected ankle on area of approximately 200 square centimeters (cm\^2). DDEA 2.32% gel will be applied in morning and late afternoon and Placebo gel will be applied in noon and late evening for 7 days.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • A participant who is willing and able to comply with scheduled visits, treatment plan and other study procedures.
  • A participant with acute sprain of the lateral ankle on one side only, Grade I-II.
  • A participant who had pain-on-movement greater than or equal to (\>=) 50 mm on a 100 mm VAS.
  • A participant with injury within the past 24 hours before randomization.
  • Participant had not taken pain medication within the 24 hours that precedes randomization.Treatment by rest, ice, compression, or elevation (RICE) is authorized prior to randomization. Stable daily doses of acetylsalicylic acid (less than or equal to \[\<=\] 162 mg) taken for at least 30 days prior to the first dose of study medication for non-analgesic reasons may be continued for the duration of the study.
  • A participant in good general and mental health with, in the opinion of the investigator or medically qualified designee with no clinically significant/relevant abnormalities in medical history or upon physical examination, or condition, that would impact the participant's safety, wellbeing or the outcome of the study, if they were to participate in the study, or affect the individual's ability to understand and follow study procedures and requirements.
  • Female participant of childbearing potential and at risk for pregnancy must agree to use a highly effective method of contraception throughout the study and for 14 days after the last dose of assigned treatment.

You may not qualify if:

  • A participant with Grade I-III sprain of the affected ankle during the past 3 months.
  • A participant with Grade II-III sprain, any other significant injury (such as fracture or torn ligament), or surgery (except for skin or nails) of the affected ankle or foot during the past 6 months.
  • A participant with pain or instability in the affected ankle attributable to previous ankle sprain or any other trauma.
  • A participant with ankle sprain attributable to a known disease affecting the ligaments, such as ligament hyperlaxity due to connective tissue diseases (e.g. Marfan's syndrome, Down's syndrome, Ehlers-Danlos syndrome).
  • A participant who has any skin lesion or wound in the area to be treated.
  • A participant who intent to undergo surgery during time of participation.
  • A participant who is an employee of the investigational site, either directly involved in the conduct of the study or a member of their immediate family; or an employee of the investigational site otherwise supervised by the investigator; or, a GSK CH employee directly involved in the conduct of the study or a member of their immediate family.
  • A participant with,in the opinion of the investigator or medically qualified designee, an acute or chronic medical, including other current acute or chronic pain conditions, or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator or medically qualified designee, would make the participant inappropriate for entry into this study.
  • A participant who is a pregnant female.
  • A participant who is a breastfeeding female.
  • A participant with known or suspected intolerance or hypersensitivity to the study materials (or closely related compounds) or any of their stated ingredients.
