Brief Summary:
In this project, we aimed at developing new "Ready-to-Use" inhalable forms of HCQ that can be used directly through nebulization or using dry powder inhalers (DPIs). These inhaled forms would allow a simple and direct delivery of the drug (HCQ) specifically towards the throat and the lung which are the main sites for the COVID-19 viral infection. Hence, the drug can be available at higher concentrations in the throat and lungs as compared with the currently used treatment protocols, while minimizing the drug systemic concentrations and its presence in other body organs, and thus enhancing the drug efficacy with significantly limiting its side effects. Besides, using inhalable forms can be more convenient to patients suffering from gastrointestinal complications from the disease that can limit the absorption of oral forms. Moreover, the proposed inhalable forms are designed in such a way to hide the drug from the immune system (confer stealth characteristics) using FDA-approved excipients to minimize/avoid any immune response towards the drug as was noted towards it in its oral form that's used in the treatment protocol of COVID-19. In addition, the inhaled formulations will be designed to maintain the overall simplicity and scalability of the preparation which is critical during this urgent pandemic situation. The cost of the final formulation is also taken into consideration since the drug is intended for treatment of thousands or probably millions of patients around the world including countries with limited economic capabilities.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Intervention Model Description: The first 20 consecutive patients (group A) will be treated by oral antibiotics, supportive treatment and inhalable hydroxychloroquine (HCQ). (In day 1, an inhaled hydroxychloroquine sulfate dose of 12 mg will be taken via nebulization three times/day (TID) as a loading dose. Then, starting from day 2, same dose of 12 mg of inhaled hydroxychloroquine will be taken twice/day (BID) as maintenance dose for 5 days. The subsequent 20 consecutive patients (group B) will receive the same treatment of group A but without inhalable hydroxychloroquine (HCQ). At day 7, all patients of both groups will be evaluated by clinical, laboratory and chest CT parameters. Patients of group B who still show no clinical, laboratory or radiological improvement will continue treatment by adding inhalable hydroxychloroquine (HCQ). for another 7 days and re-evaluated at day 14. Patients of group A who still show no significant improvement at day 7 only will be re-checked at day 14.
