Safety Study of Fenretinide in Adult Patients With Cystic Fibrosis

• Status: Completed
• Trial end date: 2015-02-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to assess the safety and tolerability of ascending doses of a novel oral formulation of Fenretinide to adult cystic fibrosis (CF) patients, once-daily for 21 days (treatment cycle). This study will include up to three (3) dose levels with minimum 7 day breaks in between treatment cycles. For each dose level, blood samples will be collected for exploratory pharmacokinetic (PK) and pharmacodynamic (PD) evaluation.

Criteria

Inclusion Criteria:

• Signed Informed Consent

• Males or females

• Diagnosis: Patients must have a diagnosis of cystic fibrosis (positive sweat chloride test) or confirmation of two genetic mutations, one mutation on each of the two alleles of the Cystic fibrosis transmembrane conductance regulator (CFTR) gene causing Cystic Fibrosis

• Chronic cystic fibrosis lung disease with baseline Forced Exploratory Volume in one second equal or superior to 40% predicted value for age, gender and height

• Clinically stable patients will be enrolled in the study, i.e. stable at least one month after successful treatment of pulmonary exacerbation

• Chronic pulmonary Pseudomonas aeruginosa colonization and/or infection (sustained microbiological evidence from sputum for the past 6 months, prior to enrollment)

• Pancreatic function: Patient must take pancrelipase supplementation if diagnosed with pancreatic insufficiency as prescribed by a physician. Enzyme supplementation should not be modified during the trial

• Female patients should be on an effective contraceptive method during the study.

Exclusion Criteria:

• Pregnancy : due to the potential teratogenic effects of retinoids, pregnant women are NOT eligible

• Breastfeeding by study patient is NOT allowed

• Clinically abnormal renal function: Serum Creatinine > 132 micromoles/L

• Clinically abnormal liver function: Total bilirubin >1.5 x Upper Limit of the Normal range (ULN), Alanine Aminotransferase (ALT) and/or Aspartate AminoTransferase (AST) > 3 x ULN and Alkaline Phosphatase (ALP) > 2 x ULN

• Known history of a severe allergy or sensitivity to retinoids

• Presence of a cancerous tumor, active or in remission, treated or not

• Presence of nyctalopia or hemeralopia at enrolment, or any other serious retinal, ophthalmological condition (eg: retinitis pigmentosa, choroidoretinitis and xerophthalmia), including glaucoma

• Presence of serious dermatological conditions at entry, including inflammatory or xerotic pathologies such as psoriasis or ichthyosis

• Prior therapy with Fenretinide. Other retinoids (eg: vitamin A supplements) are allowed, but their dosing regimen should remain constant throughout the study

• Participation in another drug clinical trial within 30 days prior to the enrollment

• Patients who, in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study

• Patients unable to comply with the study protocol and follow-up schedule for any psychological, familial, sociological or geographical reason.
