In addition, patients should be instructed to inhale their HS at least 30 minutes before their pulmonary function tests (PFT). Patients should be consistent with the timing of taking their HS at home or clinic, prior to their PFT. • Personal history of abnormal hearing or family history of abnormal hearing other than typical hearing loss associated with the aging process. • Abnormal result from any audiology testing (defined as either a unilateral pure-tone audiometry test showing a threshold elevation > 20 dB at any frequency across the frequency range 0.25 kHz to 8 kHz or the absence of emission at the evoked otoacoustic emission test). • History of sputum culture or throat swab (or BAL) culture yielding Burkholderia cepacia (B. cepacia) within 2 years prior to screening for CTBM100C2303 and/or sputum culture yielding B. cepacia at screening for CTBM100C2303 or at enrollment into this study. • Hemoptysis of more than 60 cc at any time within 30 days prior to study drug administration. • History of malignancy of any organ system (other than localized basal cell carcinoma of the skin), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases, • Patients with clinically significant laboratory abnormalities (unless expected under the study indication) at the termination of CTBM100C2303 / visit 4, especially if meeting the relevant criteria for premature withdrawal defined under 6.5.8. • Subjects or caregivers with a history of noncompliance to medical regimens and patients or caregivers who are considered potentially unreliable. • Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test (> 5 mIU/mL). • Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, including women whose career, lifestyle, or sexual orientation precludes intercourse with a male partner and women whose partners have been sterilized by vasectomy or other means, UNLESS they are using two birth control methods. The two methods can be a double barrier method or a barrier method plus a hormonal method (as defined per protocol).

E.5 End points |
E.5.1 | Primary end point(s) |
Safety: A complete physical examination will be performed at visits 5, 8 and 9. Vital signs will be assessed at every visit. Single measurements will be performed at visit 9. During the other visits (visits 5 through 8), there will be assessments of vital signs before and 30 minutes after the inhalation of study medication (referred to as pre-dose and post-dose measurements, respectively).Hemoglobin, hematocrit, red blood cell count, white blood cell count with differential, and platelet count will be measured at all visits (5 – 9) and in case of premature study discontinuation also at the discontinuation visit.Blood urea, creatinine, total bilirubin, AST, ALT, alkaline phosphatase, sodium, potassium, chloride, calcium, phosphorous, total protein, albumin, and uric acid will be measured at all visits (5 – 9) and in case of premature study discontinuation also at the discontinuation visit.Dipstick measurements for specific gravity, protein, glucose and blood will be done at all visits (5 – 9). WBC and RBC sediments will also be measured.Audiological assessments will be conducted at selected study sites at visits 5, 6 and 8, and – if findings at previous visits are abnormal and clinically significant or in case the patient is withdrawn prematurely – at visit 9. the following safety-endpoints will also be assessed: • Adverse events from time of first administration of study drug until study completion. Adverse events occurring before starting study treatment but after signing the informed consent form are recorded on the Medical History/Current Medical Conditions Case Report Form. • Incidence of treatment-emergent adverse-events (AEs). • Serious adverse events from time of consent until 4 weeks after study completion. • Concomitant medications/Significant non-drug therapies • Acute change in airway reactivity (FEV1 percent predicted) from pre-dose to 30 minutes after completion of first dose of study drug (where a change of 20% or more is considered clinically significant as bronchospasm). The use of aminoglycosides in humans has been related to audiological impairment [Guthrie, 2008]. Even though no case of hearing loss has been observed in TIP or TOBI studies so far, the audiological assessment (7.5.6) has been included into this study to closely monitor the hearing ability of subjects exposed to TIP. Renal function is surveyed by clinical chemistry assessments, as nephrotoxic effects of aminoglycosides have been reported [Martinez-Saldago, 2007]. All other safety assessments selected are standard for the indication cystic fibrosis and this patient population.
