Inclusion criteria

Key Inclusion Criteria: * Body mass index (BMI) of 18 to 32 kg/m2 * A diagnosis of moderate asthma (according to GINA 2015) for a period of at least 2 years prior to screening. * Patient must use a stable medium daily dose level of inhaled corticosteroids (ICS) as defined by GINA guidelines, ie, total daily dose of ICS \>400 μg and ≤800 μg/day of budesonide or equivalent for at least 1 month prior to screening and during the study * A pre-bronchodilator forced expiratory volume in the first sec (FEV1) ≥60% and ≤90% of the predicted normal values at screening and pre-dose at screening * A documented positive response to the reversibility test at the screening, defined as improvement in FEV1 ≥12% and ≥200 mL over baseline after 400 μg salbutamol Pmdi * Willing and able to comply with clinic visits and study-related procedures * Provide signed informed consent. Key

Exclusion criteria

* Clinically significant abnormal CBC, clinical chemistry, and urine analysis at screening. * Treatment with an investigational drug within 8 weeks or within 5 half-lives (if known), whichever is longer, prior to screening. * History of life-threatening asthma * Occurrence of asthma exacerbations or respiratory tract infections within 4 weeks prior to screening. * Diagnosis of any other airway/pulmonary disease such as Chronic Obstructive Pulmonary Disease (COPD) as defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines (GOLD 2016); or other lung diseases (eg, emphysema, idiopathic pulmonary fibrosis, Churg-Strauss syndrome, allergic bronchopulmonary aspergillosis cystic fibrosis, bronchiectasis or alpha-1 antitrypsin deficiency or restrictive lung disease). * Chronic or acute infection requiring treatment with systemic antibiotics, antivirals, or antifungals within 1 month prior to screening. * Use of oral antibiotics/anti-infectives within 2 weeks prior to screening. * Known sensitivity to doxycycline or tetracyclines, or to any of the components of the investigational product formulation. * Recent (within the previous 2 months) bacterial, protozoal, viral, or parasite infection. * History of tuberculosis or systemic fungal diseases * Patients treated with a monoclonal antibody based therapy (such as an anti-IgE, anti-IL-5), a biologic therapy or immunotherapy (subcutaneous immunotherapy \[SCIT\], sublingual immunotherapy \[SLIT\], or oral immunotherapy \[OIT\]) in the previous 12 weeks prior to screening and during the study Note: Other protocol defined Inclusion/
