Study to Evaluate the Safety and Tolerability of Mucinex™(Guaifenesin) 600 mg Extended-Release Bi-Layer Tablets in the Treatment of Otherwise Healthy Patients With Symptoms of Cough, Thickened Mucus and Chest Congestion

An Open Label, Multicentric Study to Evaluate the Safety and Tolerability of Mucinex™(Guaifenesin) 600 mg Extended-Release Bi- Layer Tablets in the Treatment of Otherwise Healthy Patients With Symptoms of Cough, Thickened Mucus and Chest Congestion

This was an open label, multicentric, non-comparative, single arm prospective post marketing surveillance (PMS) study to evaluate the safety and tolerability of Mucinex™ (GGE, 600 mg ER bi-layer tablets, taken as 1200 mg BID dose) in the treatment of otherwise healthy patients with symptoms of cough, thickened mucus and chest congestion due to URTI. Symptomatic patients who visited the outpatient department of hospitals and clinics or general physicians and had agreed to participate in this study were screened and enrolled into the study.

Study Overview

• Status: Completed
• Conditions: Healthy Subjects
• Intervention / Treatment: Drug: Mucinex™ extended-release (SE)

• Study Type: Interventional
• Enrollment (Actual): 552
• Phase: Phase 4

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 16 years to 80 years (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

Patients were eligible for enrolment in the study if they fulfilled the following criteria:

1. Males and females (non-pregnant) patients of ≥ 18 years of age.

2. Otherwise healthy patients suffering from cough with symptoms of thickened mucus and chest congestion and a diagnosis of any one of the following:

   • Acute Bronchitis
   • Upper Respiratory Tract Infections (URTI) such as naso-pharyngitis
   • Sinusitis

3. Females of child bearing potential:

   1. Must have used efficacious and reliable method of contraception during the entire duration of the study {e.g. double barrier methods (e.g., condom and spermicidal); intrauterine device (IUD) } or remained sexually inactive throughout the study*.
   2. Must have had a negative urine pregnancy test (UPT) at Screening/Baseline (test must have a sensitivity of at least 25 mIU/mL for HCG).
   3. Must have been non-lactating.
4. Patients must have demonstrated their willingness to participate in the study and comply with the study procedures and required visits.
5. Patients must have been willing to authorize use and disclosure of protected health information collected for the study.

6. Patients must have had the ability to understand and sign a written consent, which had to be signed prior to study specific procedures being performed.

   • *Abstinence (sexually inactive) was not an acceptable form of contraception; however, abstinent female patients could have been admitted to the study if they agreed, and signed a statement to the effect, that upon becoming sexually active, they would use a condom with spermicide from that time through 30 days beyond completion of the study (Visit 2).

Exclusion Criteria:

Patients were excluded from the study if they fulfilled any of the following:

1. Females who were pregnant or lactating or planning to become pregnant during the study period.
2. Patients with a history of chronic cough of > 3 weeks duration.

3. Patients with any of the following conditions:

   • Asthma
   • Chronic bronchitis
   • Emphysema
   • Other chronic pulmonary conditions such as Chronic Obstructive Pulmonary Disease (COPD) or cystic fibrosis (CF), etc.
4. Patients with known hypersensitivity to GGE.
5. Patients with temperature greater than 101°F (38.3°C) at Screening/Baseline.
6. Patients with a serious and/or uncontrolled medical condition (chronic or active liver disease, renal impairment, heart disease, diabetes, severe respiratory disease, rheumatoid arthritis, current malignancies, immunocompromised conditions or any other disease) that in the opinion of the investigator would interfere with the study or place the patient at unacceptable risk.
7. Patients with a history or examination findings of alcohol dependence, alcohol or drug abuse or suspected abuse within the past 2 years.
8. Patients who had participated in a study of an investigational drug within 30 days prior to the Screening/Baseline visit.
9. Patients who in the opinion of the investigator were unable to comply fully with the study requirements.
10. Related to persons involved directly or indirectly with the conduct of this study [i.e., investigator, sub-investigators, study coordinators, other study personnel, employees of Reckitt Benckiser or Ecron AcuNova Ltd. (EAL), formerly known as Manipal Acunova Limited (MAL) and the families of each].

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Adverse Events (AEs), Type of AE(s) and Frequency of AE(s)	Treatment Emergent Adverse Event (TEAE) are events occurring after the first dose of study medication. Frequency of AE(s) - the total Number of Events Type of AE(s) - Serious TEAE and Non serious TEAE	Up to Day 9
Number of Subjects Affected With Adverse Events	Proportion of patients with AE(s) - Number of Subjects affected with Events	Up to Day 9
Number of Adverse Events by Severity, Seriousness and the Relationship of AE(s) to Treatment	Intensity determined. Mild = AE did not limit usual activities; subject may have experienced slight discomfort. Moderate = AE resulted in some limitation of usual activities; subject may have experienced significant discomfort. Severe = AE resulted in an inability to carry out usual activities; subject may have experienced intolerable discomfort/pain. Relationship to Investigational Medicinal Products (IMP) Unassessable/Unclassified = Insufficient information to be able to make an assessment Conditional/ Unclassified = Insufficient information to make an assessment at present Unrelated = No possibility that the AE was caused by the IMP Unlikely = Slight, but remote, chance that the AE was caused by the IMP, but the balance of judgment was that it was most likely not due to the IMP. Possible = Reasonable suspicion that the AE was caused by the IMP Probable = Most likely that the AE was caused by the IMP Certain = AE was definitely caused by the IMP	Up to Day 9

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Assessment of the Study Medication by End of Study Patient Questionnaire	End of Study Patient Questionnaire is a questionnaire provided to the patients for overall assessment of the study medication at the end of study visit. Satisfied(stfd) Dissatisfied(Dstfd)	Up to Day 9
Overall Assessment of the Study Medication by End of Study Investigator Questionnaire	End of Study Investigator Questionnaire is a questionnaire provided at the end of study visit to the investigator (or sub-investigator as applicable) for overall assessment of the study medication across all patients treated by them.
