About this study
Official title: An Observer-blind Study to Evaluate the Safety, Reactogenicity and Immunogenicity of the Investigational GSK Biologicals' COPD Vaccine (GSK3277511A) in Adults
The purpose of this study is to test two different vaccine schedules to be used for administering the investigational NTHi Mcat vaccine that will be targeting patients with chronic obstructive pulmonary disease (COPD) to prevent acute exacerbations. An acute exacerbation is when the breathlessness in COPD patients will get even worse than it normally already is, sometimes to the point where oxygen therapy is required.
In previous studies, study participants have received two doses of the vaccine according to a 0, 2 month vaccination schedule, in addition to standard care. The current study will find out if a third dose of the study vaccine against NTHi/Mcat is safe and working well. The study will also investigate if the third dose of vaccine works best when given after 6 months or after 12 months.
Read the detailed description
The purpose of this Phase 2 study is to evaluate two vaccine schedules of the investigational NTHi-Mcat vaccine.
As the prevalence of COPD increases with age and as age has an influence on both the immunogenicity and reactogenicity of a vaccine, subjects 40-80 years old will be enrolled. As cigarette smoking is the most commonly encountered risk factor for COPD, adults with a smoking history of at least 10 pack-years will be selected in order to immunologically match the COPD population as much as possible. Literature data indeed suggest that alterations of the immune system start early on in smokers, before the COPD disease is recognized [Barcelo et al 2008; Droemann et al, 2005; Takanashi et al, 1999].
Several formulations of a vaccine containing the NTHi antigens (10 or 30 µg) either non-adjuvanted or combined with different adjuvants (aluminium [Al], adjuvant system [AS]01E and AS04C) were already evaluated in two previous Phase 1 clinical trials (NTHI-002 in healthy adults aged 18 - 40 years and NTHI-003 in current and former healthy smokers of 50-70 years old). The investigational vaccines were well-tolerated, with an acceptable safety and reactogenicity profile. These studies allowed the dose selection of the NTHi antigens (10 µg) and the adjuvant system (AS01E) evaluated for the first time in moderate and severe COPD patients aged 40-80 years in the Phase 2 study NTHI-004.
The safety, reactogenicity and immunogenicity of different formulations of the NTHi-Mcat investigational vaccine have been evaluated in the Phase 1 study in healthy adults aged 18-40 years and in current and former smokers aged 50-70 years (study NTHI MCAT-001). Based on results obtained up to 30 days post-Dose 2 from this study, the AS01E-adjuvanted formulation containing 10 µg of NTHi proteins PD and PE-PilA and 3.3 µg of UspA2 has been selected for evaluation in the current NTHI MCAT-008 study. The current study will evaluate the impact of a 3rd dose (following a 0-2 month vaccination schedule), either given at 6 months or at 12 months after the first dose. The primary aim is to assess the safety of the additional dose. The study will also investigate how the two schedules improve the persistence of antibody response.
To this end, adults aged 40 to 80 years with a smoking history of at least 10 pack-years, will receive 2 doses of the NTHi-Mcat investigational vaccine at 0 and 2 months in both study arms. Following these 2 doses, one study arm will receive a 3rd dose of the investigational NTHi-Mcat vaccine at 6 months and a placebo control at 12 months (Schedule 1) and the other study arm will receive a placebo control at 6 months and a 3rd dose of the investigational NTHi-Mcat vaccine at 12 months (Schedule 2).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to test two different vaccine schedules to be used for administering the investigational NTHi Mcat vaccine that will be targeting patients with chronic obstructive pulmonary disease (COPD) to prevent acute exacerbations. An acute exacerbation is when the breathlessness in COPD patients will get even worse than it normally already is, sometimes to the point where oxygen therapy is required.
In previous studies, study participants have received two doses of the vaccine according to a 0, 2 month vaccination schedule, in addition to standard care. The current study will find out if a third dose of the study vaccine against NTHi/Mcat is safe and working well. The study will also investigate if the third dose of vaccine works best when given after 6 months or after 12 months.
Detailed description
The purpose of this Phase 2 study is to evaluate two vaccine schedules of the investigational NTHi-Mcat vaccine.
As the prevalence of COPD increases with age and as age has an influence on both the immunogenicity and reactogenicity of a vaccine, subjects 40-80 years old will be enrolled. As cigarette smoking is the most commonly encountered risk factor for COPD, adults with a smoking history of at least 10 pack-years will be selected in order to immunologically match the COPD population as much as possible. Literature data indeed suggest that alterations of the immune system start early on in smokers, before the COPD disease is recognized [Barcelo et al 2008; Droemann et al, 2005; Takanashi et al, 1999].
Several formulations of a vaccine containing the NTHi antigens (10 or 30 µg) either non-adjuvanted or combined with different adjuvants (aluminium [Al], adjuvant system [AS]01E and AS04C) were already evaluated in two previous Phase 1 clinical trials (NTHI-002 in healthy adults aged 18 - 40 years and NTHI-003 in current and former healthy smokers of 50-70 years old). The investigational vaccines were well-tolerated, with an acceptable safety and reactogenicity profile. These studies allowed the dose selection of the NTHi antigens (10 µg) and the adjuvant system (AS01E) evaluated for the first time in moderate and severe COPD patients aged 40-80 years in the Phase 2 study NTHI-004.
The safety, reactogenicity and immunogenicity of different formulations of the NTHi-Mcat investigational vaccine have been evaluated in the Phase 1 study in healthy adults aged 18-40 years and in current and former smokers aged 50-70 years (study NTHI MCAT-001). Based on results obtained up to 30 days post-Dose 2 from this study, the AS01E-adjuvanted formulation containing 10 µg of NTHi proteins PD and PE-PilA and 3.3 µg of UspA2 has been selected for evaluation in the current NTHI MCAT-008 study. The current study will evaluate the impact of a 3rd dose (following a 0-2 month vaccination schedule), either given at 6 months or at 12 months after the first dose. The primary aim is to assess the safety of the additional dose. The study will also investigate how the two schedules improve the persistence of antibody response.
To this end, adults aged 40 to 80 years with a smoking history of at least 10 pack-years, will receive 2 doses of the NTHi-Mcat investigational vaccine at 0 and 2 months in both study arms. Following these 2 doses, one study arm will receive a 3rd dose of the investigational NTHi-Mcat vaccine at 6 months and a placebo control at 12 months (Schedule 1) and the other study arm will receive a placebo control at 6 months and a 3rd dose of the investigational NTHi-Mcat vaccine at 12 months (Schedule 2).

Primary outcome
Number of Subjects Reported With Each Solicited Local Adverse Event (AE) (Any and Grade 3) Within Each Vaccination Schedule
Time frame: During the 7-day follow-up period (the day of vaccination + 6 days) after each vaccination administered at Day 1, Day 61, Day 181 and Day 361
Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 100 millimeters (mm) injection site.
Number of Subjects Reported With Each Solicited General Adverse Event (AE) (Any and Grade 3) Within Each Vaccination Schedule
Time frame: During the 7-day follow-up period (the day of vaccination + 6 days) after each vaccination administered at Day 1, Day 61, Day 181 and Day 361
Assessed solicited general symptoms were chills, gastrointestinal symptoms (including nausea, vomiting, diarrhoea and/or abdominal pain), fatigue, myalgia, headache and fever [defined Oral cavity or axillary temperature equal to or above (≥) 37.5 degrees Celsius (°C)]. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever ≥ 39.0 °C.
Number of Subjects Reported With Any Unsolicited Adverse Event (AE) Within Each Vaccination Schedule
Time frame: During the 30-day follow-up period (the day of vaccination + 29 days) after each vaccination administered at Day 1, Day 61, Day 181 and Day 361
An AE is any untoward medical occurrence in a clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. Unsolicited AE is any AE reported in addition to those solicited during the clinical study. Also any 'solicited' symptom with onset outside the specified period of follow-up for solicited symptoms was reported as an unsolicited adverse event.
Number of Subjects Reported With Any Serious Adverse Event (SAE) Within Each Vaccination Schedule
Time frame: From first vaccination (Day 1) up to Day 541 (an average of 18 months)
An SAE is defined as any untoward medical occurrence that resulted in death, was life-threatening, required hospitalization or prolongation of hospitalization, resulted in disability/incapacity in a subject or was a congenital anomaly/birth defect in the offspring of a study subject. AE(s) considered as SAE(s) also include invasive or malignant cancers, intensive treatment in an emergency room or at home for allergic bronchospasm, blood dyscrasias or convulsions that do not result in hospitalization, as per the medical or scientific judgement of the physician.
Number of Subjects Reported With Any Potential Immune-mediated Diseases (pIMDs) Within Each Vaccination Schedule
Time frame: From first vaccination (Day 1) up to Day 541 (an average of 18 months)
Potential immune-mediated diseases (pIMDs) are a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune aetiology.
