Chronic Obstructive Pulmonary Disease (COPD) | Drug: Placebo Drug: TrIP-2D Drug: TrIP-2SS Drug: TrIP-2SS + Foradil | Phase 2 |
This was a single-center, randomized, double-blind, cross-over, placebo-controlled study. Following screening, each eligible subject was randomized to a dosing sequence. Study subjects received a total of 5 single doses, each separated by a 3- to 14-day washout period. Doses A, B, C, and D were administered in a double-blind fashion, in sequences generated by a 4-period Latin square design. The 4 dosing sequences were: ABCD, BDAC, CADB, and DCBA. Dose E was administered in an open-label fashion as the final dose in each dosing sequence for all subjects.
Subjects reported to the clinic the evening prior to each dose. Protocol assessments were carried out until 24 hours postdose. Pulmonary function testing (via spirometry) was captured at specified timepoints at baseline as well as before and after dosing. Other efficacy and safety outcomes were assessed according to protocol. Blood sampling was performed for assessment of trospium concentrations at specified timepoints.

Placebo Comparator: Placebo
Represents Dose A in the Dosing Sequence assignments.
|
Drug: Placebo
Supplied as an empty size-2 capsule and administered as a single dose via C2S inhaler.
|
Experimental: TrIP-2D (100mcg)
Represents Dose B
|
Drug: TrIP-2D
Trospium inhalation powder containing 100 mcg TrCl (trospium chloride), supplied as dry powder in size-2 capsules and administered as a single dose via C2S inhaler.
|
Experimental: TrIP-2SS (100mcg)

|
Drug: TrIP-2SS
Trospium inhalation powder containing 100 mcg TrCl (trospium chloride), supplied as dry powder in size-2 capsules and administered as a single dose via C2S inhaler.
|
Experimental: TrIP-2D (400mcg)
Represents Dose D
|
Drug: TrIP-2D
Trospium inhalation powder containing 400 mcg TrCl (trospium chloride), supplied as dry powder in size-2 capsules and administered as a single dose via C2S inhaler.
|
Experimental: TrIP-2SS (100mcg) + Foradil (12mcg)
Represents Dose E. All subjects received Dose E as their final (5th) dose, after completing their initial 4 single doses according to their sequence assignment.
|
Drug: TrIP-2SS + Foradil
Trospium inhalation powder containing 100 mcg TrCl (trospium chloride), plus foradil (12 mcg formoterol fumarate) supplied as dry powder in size-2 capsules and administered as a single dose via C2S inhaler.

- Spirometry Parameter: Peak Forced Expiratory Volume in 1 Second(FEV1)in Liters (L) [ Time Frame: 15 minutes to 24 hours post-treatment ]
Following screening, each subject was randomized to a sequence of 5 dosing periods (Doses A, B, C, D, and E). Each period was separated by a 3- to 14-day washout interval.
The dosing formulations were as follows:
Dose A = placebo Dose B = TrIP-2D (100 μg TrCl formulated in leucine and DPPC) Dose C = TrIP-2SS (100 μg TrCl formulated in leucine and sodium saccharin) Dose D = TrIP-2D (400 μg TrCl) Dose E = TrIP-2SS (100 μg TrCl) + Foradil (12 μg formoterol fumarate) FEV1 (L)was measured at 15 and 30 minutes, 1, 2, 3, 4, 6, 8, 12 and 24 hours postdose.
- FEV1 Response to Treatment [ Time Frame: Up to 24 hours post-treatment ]Response was defined as the number of subjects reporting a post-treatment FEV1 of ≥12% (or 200 mL) above baseline.
- Time to Maximum Plasma Concentration (Tmax) of Trospium After Single Administrations of TrIP [ Time Frame: up to 24 hours post-treatment ]Tmax is reported as median (range) of hours to reach maximum trospium concentration in plasma.
