STOP 301: A Phase 3, open-label study of safety, tolerability, and exploratory efficacy of INP104, Precision Olfactory Delivery (POD® ) of dihydroergotamine mesylate, over 24/52 weeks in acute treatment of migraine attacks in adult patients.

OBJECTIVE: To report the safety, tolerability, exploratory efficacy, and patient acceptability of INP104 for the acute treatment of migraine from the Phase 3 STOP 301 trial. BACKGROUND: Dihydroergotamine (DHE) has long been used to treat migraine, but intravenous administration is invasive, frequently associated with adverse events (AEs), and not suitable for at-home administration. INP104 is an investigational drug device that delivers DHE mesylate to the upper nasal space using a Precision Olfactory Delivery technology and was developed to overcome the shortcomings of available DHE products. METHODS: STOP 301 was an open-label, 24-week safety study, with a 28-week extension period. After a 28-day screening period where patients used their "best usual care" to treat migraine attacks, patients were given INP104 (1.45 mg) to self-administer nasally with self-recognized attacks. The primary objective of this study was to assess safety and tolerability, with a specific focus on nasal mucosa and olfactory function. Exploratory objectives included efficacy assessments of migraine measures and a patient acceptability questionnaire. RESULTS: A total of 360 patients entered the 24-week treatment period, with 354 patients dosing at least once. INP104-related treatment-emergent AEs were reported by 36.7% (130/354) of patients, and 6.8% (24/354) discontinued treatment due to AEs over 24 weeks. No new safety signals were observed following delivery to the upper nasal space. Pain freedom, the most bothersome symptom freedom, and pain relief at 2 h post-INP104 were self-reported by 38.0% (126/332), 52.1% (173/332), and 66.3% (167/252) of patients, respectively. A low recurrence rate at 24 and 48 h was observed (7.1% [9/126] and 14.3% [18/126], respectively). Most patients found INP104 easy to use and preferred it over their current therapy. CONCLUSIONS: INP104 has the potential to deliver rapid symptom relief, without injection, that is well tolerated and suitable for outpatient use. Results suggest INP104 may be a promising treatment for patients with migraine.

Effect of azithromycin on pulmonary function in patients with cystic fibrosis uninfected with Pseudomonas aeruginosa: a randomized controlled trial.

CONTEXT: Azithromycin is recommended as therapy for cystic fibrosis (CF) patients with chronic Pseudomonas aeruginosa infection, but there has not been sufficient evidence to support the benefit of azithromycin in other patients with CF. OBJECTIVE: To determine if azithromycin treatment improves lung function and reduces pulmonary exacerbations in pediatric CF patients uninfected with P. aeruginosa. DESIGN, SETTING, AND PARTICIPANTS: A multicenter, randomized, double-blind placebo-controlled trial was conducted from February 2007 to July 2009 at 40 CF care centers in the United States and Canada. Of the 324 participants screened, 260 were randomized and received study drug. Eligibility criteria included age of 6 to 18 years, a forced expiratory volume in the first second of expiration (FEV(1)) of at least 50% predicted, and negative respiratory tract cultures for P. aeruginosa for at least 1 year. Randomization was stratified by age of 6 to 12 years vs 13 to 18 years and by CF center. INTERVENTION: The active group (n = 131) received 250 mg (weight 18-35.9 kg) or 500 mg (weight > or = 36 kg) of azithromycin 3 days per week (Monday, Wednesday, and Friday) for 168 days. The placebo group (n = 129) received identically packaged placebo tablets on the same schedule. MAIN OUTCOME MEASURES: The primary outcome was change in FEV(1). Exploratory outcomes included additional pulmonary function end points, pulmonary exacerbations, changes in weight and height, new use of antibiotics, and hospitalizations. Changes in microbiology and adverse events were monitored. RESULTS: The mean (SD) age of participants was 10.7 (3.17) years. The mean (SD) FEV(1) at baseline and 168 days were 2.13 (0.85) L and 2.22 (0.86) L for the azithromycin group and 2.12 (0.85) L and 2.20 (0.88) L for the placebo group. The difference in the change in FEV(1) between the azithromycin and placebo groups was 0.02 L (95% confidence interval [CI], -0.05 to 0.08; P = .61). None of the exploratory pulmonary function end points were statistically significant. Pulmonary exacerbations occurred in 21% of the azithromycin group and 39% of the placebo group. Participants in the azithromycin group had a 50% reduction in exacerbations (95% CI, 31%-79%) and an increase in body weight of 0.58 kg (95% CI, 0.14-1.02) compared with placebo participants. There were no significant differences between groups in height, use of intravenous or inhaled antibiotics, or hospitalizations. Participants in the azithromycin group had no increased risk of adverse events, but had less cough (-23% treatment difference; 95% CI, -33% to -11%) and less productive cough (-11% treatment difference; 95% CI, -19% to -3%) compared with placebo participants. CONCLUSION: In children and adolescents with CF uninfected with P. aeruginosa, treatment with azithromycin for 24 weeks did not result in improved pulmonary function.

The SNAP 101 Double-Blind, Placebo/Active-Controlled, Safety, Pharmacokinetic, and Pharmacodynamic Study of INP105 (Nasal Olanzapine) in Healthy Adults.

OBJECTIVE: INP105 is a drug-device combination of olanzapine and technology that delivers a powder formulation of olanzapine to the vascular-rich upper nasal space. This study evaluated the pharmacokinetics, pharmacodynamics, safety, and tolerability of single ascending doses of INP105, olanzapine intramuscular (OLZ IM), and olanzapine oral disintegrating tablet (OLZ ODT). METHODS: This was a phase 1, active and double-blind placebo comparator-controlled, ascending-dose, 2-period, incomplete-block, 1-way crossover study in 40 healthy subjects, randomized to single doses of OLZ IM (5 or 10 mg) or OLZ ODT (10 mg) in Period 1 and then 1 of 3 doses (5 mg, 10 mg, or 15 mg) of INP105 or placebo in Period 2 between July and October 2018. Sedation and attention were evaluated by visual analog scale (VAS), the Agitation/Calmness Evaluation Scale (ACES), and the Digit Symbol Substitution Test (DSST). RESULTS: At equivalent doses, INP105 provided similar area under the drug concentration-time curve (AUC) from time 0 to the last measurable concentration, AUC from time 0 to infinity, and maximum observed concentration (Cmax) as OLZ IM and greater Cmax than but similar AUCs to OLZ ODT. Median time to maximum concentration was less for INP105 (15, 10, and 9.5 min for 5 mg, 10 mg, and 15 mg, respectively) than for OLZ IM (20 and 15 min for 5 mg and 10 mg, respectively) or OLZ ODT (120 min). Effects as measured with the VAS, ACES, and DSST with INP105 5 mg were comparable to those with OLZ IM 5 mg, with earlier onset for INP105 10 mg and 15 mg and greater effects than placebo and OLZ ODT. The incidence of treatment-emergent adverse events with INP105 5 mg, 10 mg, and 15 mg was 80%, 66.7%, and 75%, respectively, compared to 90% and 100% for OLZ IM 5 mg and 10 mg, respectively, and 83.3% for OLZ ODT; most common were dizziness, hypotension, and orthostatic symptoms. CONCLUSIONS: INP105 has rapid absorption and pharmacodynamic effects and may represent an effective, convenient, noninvasive, and well-tolerated alternative for treating acutely agitated patients by self- or caregiver administration in the home, community, or hospital environments.

Standardization of Research-Quality Anthropometric Measurement of Infants and Implementation in a Multicenter Study.

Malnutrition is one of the earliest clinical manifestations of cystic fibrosis (CF) and is associated with poorer pulmonary and cognitive outcomes and survival later in life. Infant growth can be a responsive measure for clinical research in this age group if obtained and characterized accurately. We report here the methods to standardize and implement research-quality anthropometric measurement of infants with cystic fibrosis in the Baby Observational Nutrition Study multicenter trial.
