Treatment of Asthma and Chronic Obstructive Pulmonary Disease With Anti-proliferate and Anti-inflammatory Drugs

Abstract

Embodiments of the present invention provide a method for treatment of respiratory disorders such as asthma, chronic obstructive pulmonary disease, and chronic sinusitis, including cystic fibrosis, interstitial fibrosis, chronic bronchitis, emphysema, bronchopulmonary dysplasia and neoplasia. The method involves administration, preferably oral, nasal or pulmonary administration, of anti-inflammatory and anti-proliferative drugs (rapamycin or paclitaxel and their analogues).

AI Technical Summary

Benefits of technology

[0045]In one embodiment, the present invention relates to a method for treating a respiratory system comprising inserting a balloon catheter comprising a coating layer into an airway, wherein the coating layer comprises a drug and an additive, inflating the balloon catheter and releasing the drug to a wall of the airway, deflating the balloon; and withdrawing the balloon catheter from the airway. In one aspect of this embodiment, the additive enhances absorption of the drug into tissue of the respiratory or sinus system. In another aspect of this embodiment, the additive comprises a hydrophilic part and a hydrophobic part. In another aspect of this embodiment, the drug is not enclosed in micelles or encapsulated in polymer particles. In another aspect of this embodiment, the cocating layer does not include oil, a lipid, or a polymer. In another aspect of this embodiment, the coating layer does not include a purely hydrophobic additive. In another aspect of this embodiment, the coating layer does not include a dye. In another aspect of this embodiment, the drug is chosen from paclitaxel and analogues thereof and rapamycin and analogues thereof. In another aspect of this embodiment, the additive is chosen from PEG-fatty acids and PEG-fatty acid mono and diesters, polyethylene glycol glycerol fatty acid esters, alcohol-oil transesterification products, polyglyceryl fatty acids, propylene glycol fatty acid esters, sterol and derivatives thereof, polyethylene glycol sorbitan fatty acid esters, polyethylene glycol alkyl ethers, sugars and derivatives thereof, polyethylene glycol alkyl phenols, polyoxyethylene-polyoxypropylene block copolymers, sorbitan fatty acid esters, fat-soluble vitamins and salts thereof, water-soluble vitamins and amphiphilic derivatives thereof, amino acid and salts thereof, oligopeptides, peptides and proteins, and organic acids and esters and anhydrides thereof. In yet another aspect of this embodiment, the drug can be released to the wall of the airway prior to, during, or after an asthma attack.

Problems solved by technology

This condition causes shortness of breath.

There are no therapies available today to halt the progression of COPD.

The study concluded, however, that inhaled steroids failed to alter the decline in lung function over time.

This flattens the diaphragm, impairing the ability to inhale and exhale.

Asthma episodes or attacks cause narrowing of the airways, which make breathing difficult.

Asthma attacks can have a significant impact on a patient's life, limiting participation in many activities.

In severe cases, asthma attacks can be life threatening.

Presently, there is no know cure for asthma.

In cases of chronic sinusitis, there is usually tissue damage.

Chronic sinusitis is often difficult to treat successfully, however, as some symptoms persist even after prolonged courses of antibiotics.
