Study summary

Cystic fibrosis (CF) is a progressive multisystem disorder characterized by abnormalities in the transport of chloride ions in human airway epithelial cells, leading to frequent lung infections, decreased pulmonary function, inability to properly digest food and absorb essential nutrients, and complications with many organs.

Patients with CF spend hours daily, in treatments required to manage their disease, including hours of physiotherapy and inhalation and treatment with many daily pills. CF treatment load heavy burden on patients and families and the inevitable consequence of these treatment demands is widespread non-adherence to therapy.

CFTR modulators (trade name Kalydeco, Orkambi, Simdeco) is a highly efficient drug approved to treat CF in patients with certain mutations. It is the first drug that treats the underlying cause rather than the symptoms of the disease. It is also one of the most expensive drugs, costing over $300,000 per patient per year. Despite of its proven efficacy and approved reimbursement for certain patients, non-adherence is common among CF patients, resulting from the heavy burden of daily treatment required to manage CF disease.

Read the detailed description

ReX is a hand-held, mobile device intended to provide solid oral medication on patient's demand according to a pre-programmed treatment protocol. ReX addresses poor patient adherence, tracks patient's response to treatment and enhances patient engagement to therapy. The system comprises a reusable drug dispensing unit (Dispenser), a disposable Cassette containing the prescribed medication, a cellphone app, and the ReX cloud. The Dispenser manages pill administration. It includes a touch screen which guides the user and presents patient-specific clinical surveys and therapy information. The Dispenser contains a chargeable battery and indicators demonstrating device and battery status; a pill window enabling pills to be viewed; operational sensors; and communication to an app on cellphones. The patient receives the Cassette from the pharmacy, pre-filled with his/her specific medication. The Cassette is inserted into the Dispenser where it is locked in place. All therapy and patient survey data are transferred to a patient-specific domain on DosentRx' proprietary web-based cloud, named ReX cloud.

What researchers measure

Primary outcomes

  1. Number of safety events during administration of oral oncolytic medications by ReX-C

    Safety events include: pill overdose, pill inhalation during pill ingestion, pill malformation upon dispensing and any severe adverse events related to pill intake by the ReX-C device.

    Time frame: 12 months

  2. Rate of subjects feel comfortable to use ReX-C for pill intake and medication managment and define the system as "Easy to use"

    At least 70% of subjects: A. Complete at least 6 months with Rex-C. B. Define the system as easy to use and are willing to continue using it for their medication treatment.

    Time frame: 12 months

  3. Rate of adherence (number of pill intakes) during treatment with ReX-C

    A. Adherence rate when using the ReX-C system is \> 80%. B. Adherence rate is enhanced by the following measures: * At least 80% of missed/ delayed doses recorded by ReX-C are subsequently taken by subjects following real-time reminder communication. * Subject's self-report by adherence questionnaire

    Time frame: 12 months

Secondary outcomes

  1. Rate of improvement in patients health condition when using ReX-C compared with historical data of the same subject, taking identical CFTR modulator in the conventional way

    Improvement of 10-20% in the following parameters, compared between period of ReX intervention versus historical period when same medication was taken in the conventional way. A. Reduced # of acute exacerbation B. Improved PFT C. Reduced hospitalization events D. Decreased antibiotic treatment events

    Time frame: 24 months (12 months historical data, before study initiation), 12 months ReX intervention
