Orkambi is an oral medication developed by Massachusetts-based Vertex Pharmaceuticals and approved by the U.S. Food and Drug Administration (FDA) to treat patients, ages 2 and older, with cystic fibrosis caused by a common mutation.. Cystic fibrosis is a genetic disease where patients produce too much thick, sticky mucus that damages numerous organs, but particularly the lungs and digestive tract. Thirty years after scientists discovered the defective gene that causes cystic fibrosis, two new trials show a therapy could help 90 percent of patients. Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. A thorough investigation of potential causes should be conducted and patients should be followed closely for clinical progression. Children may experience headaches, a stuffy nose, stomach pain, and an increase in the amount of phlegm. Orkambi should be taken every 12 hours with fat-containing foods, such as dairy products, nuts, and avocados, as fat helps the body better absorb the medication. Dose adjustment of dabigatran may be required to obtain the desired clinical effect. Due to inhibition of CYP3A by clarithromycin, telithromycin. Key secondary endpoints included average absolute change from baseline in sweat chloride at day 15 and week 4 and at week 24 (see Pharmacodynamic effects), absolute change from baseline in BMI at week 24, absolute change from baseline in CFQ-R Respiratory Domain through week 24. Adverse reactions are ranked under the MedDRA frequency classification: very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to < 1/1,000); very rare (< 1/10,000); and not known (frequency cannot be estimated using the available data).

A higher dose of these systemic corticosteroids may be required to obtain the desired clinical effect. Patients with one F508del mutation plus other mutations were not covered in the studies, and although the company submitted some data on use in such patients, further data was considered necessary to support . Adverse reactions identified from the 24-week, placebo-controlled, Phase 3 studies (trials 1 and 2) in patients aged 12 years and older and from a 24-week, placebo-controlled study in patients aged 6 to 11 years (trial 7), who are homozygous for the F508del mutation in the CFTR gene are presented in Table 4 and are listed by system organ class and frequency. Lumacaftor is a strong inducer of CYP3A. The treatment difference in this subgroup was comparable to that observed in patients with ppFEV1 ≥ 40. In vitro studies suggest that lumacaftor has the potential to induce CYP2B6, CYP2C8, CYP2C9, and CYP2C19; however, inhibition of CYP2C8 and CYP2C9 has also been observed in vitro. ORKAMBI is made up of lumacaftor and ivacaftor, which work on certain defects of the CFTR protein at the cellular level. * In each study, a hierarchical testing procedure was performed within each active treatment arm for primary and secondary endpoints vs. placebo; at each step, P ≤ 0.0250 and all previous tests also meeting this level of significance was required for statistical significance. Co-administration of lumacaftor/ivacaftor with itraconazole, a strong CYP3A inhibitor, did not impact the exposure of lumacaftor, but increased ivacaftor exposure by 4.3-fold. Warfarin skal forhindre trombose / emboli hos utsatte pasienter eller påskynde oppløsning av eksisterende tromber. Improvements in ppFEV1 were observed regardless of age, disease severity, sex and geographic region. Concomitant use of lumacaftor/ivacaftor with these benzodiazepines is not recommended. 13.1 Carcinogenesis, Mutagenesis,Impairment of Fertility 14 CLINICAL STUDIES 15 REFERENCES . These menstrual events occurred more frequently in the subset of female patients who were taking hormonal contraceptives (25.0%) versus patients who were not taking hormonal contraceptives (3.5%) (see section 4.5). During trials 1 and 2, adverse reactions related to increased blood pressure (e.g., hypertension, blood pressure increased) were reported in 0.9% (7/738) of patients treated with lumacaftor/ivacaftor and in no patients who received placebo. There is no experience of initiating treatment with lumacaftor/ivacaftor in patients having a pulmonary exacerbation and initiating treatment in patients having a pulmonary exacerbation is not advisable.
