About this study

Official title: Study of Adjunctive rhIL-2 Therapy in Patients With MDR-TB That Improves Efficiency and Shortens Course

Multidrug-resistant tuberculosis (MDR-TB) has emerged as a challenge worldwide. Few studies have prospectively reported outcomes in patients with pulmonary MDR-TB treated with adjunctive immunotherapy combined to standard chemotherapy. We aimed to assess whether immunotherapy with Interleukin(IL)-2 enhanced the clinical and immune effects of treatment on MDR-TB patients.We performed a multicentre prospective cohort study extend all over Jiangsu province in China. Two groups were generated based on the adjunctive rhIL-2 therapy during 24 months regiman. Bacteriological and imaging data were followed during 24 months with cure rates analysed.

Read the detailed description

IL-2 therapy regimans are expected to restore the immune response or to change the immunologic status,thus allowing the host to more efficiently contain and eradicate immune responses, primarily those against cancers and infectious diseases.To address this, we performed a prospective randomized controlled multicenter cohort study of 8-month adjunctive immunotherapy with rhIL-2 for MDR-TB patients compared with the standard chemotherapy.

This multicenter prospective clinical study was conducted at 13 tuberculosis centers (coordinating hospital specialized in tuberculosis) across Jiangsu province, China. Joined by the network system of The First Affiliated Hospital of Nanjing Medical University and CDC of Jiangsu province, participants were enrolled from 2009 to 2018. This study protocol was approved by the ethics committee of the First Affiliated Hospital of Nanjing Medical University and was performed adhering to the ethical principles of the Declaration of Helsinki. All patients provided written informed consent before enrollment. The independent data and safety of the study were monitored by the hospital monitoring committee.

Patients enrollment

Eligible MDR-TB participants were identified by triplicate-spot sputum smears that were positive for acid-fast bacilli and a positive sputum culture with resistance to both isoniazid and rifampin, as determined by susceptibility tests and rapid screening tests . The results of these assays were confirmed using an L-G medium base modified in the Jiangsu province Centers for Disease Control and Prevention(CDC).

Treatment plan for the two cohorts: The patients in rhIL-2 group were given consisted of four courses of low-dose rhIL-2 (500,000 U/m) given subcutaneously (SC) once every other day (q.o.d.) for 30 days. Four courses were carried out separately during months 1, 3, 5, and 7. All enrolled patients with pulmonary MDR-TB received a 24-month standard anti-MDR-TB chemotherapy regimen:6-month Z+KM/AM or CM + PAS/(Pa) + PTO +LFX as an intensive phase treatment, followed by an 18-month Z + LFX + PTO + PAS/(Pa) as a consolidation phase treatment.

(Z: Pyrazinamide; KM: Kanamycin; AM: Amikacin; CM: Capreomycin; LFX: Levofloxacin; PTO: Prothionamide; PAS: Para-aminosalicylicacid; Pa:Pasiniazid); After finishing treatment regimen patients were followed up for a minimum of 36- months or until discontinuation of regimen, withdrawal of consent, loss to follow-up, death, or end of study.

For all of the participants demographic measurements were recorded on the first clinical visit. Patient data were collected at enrollment and quarterly intervals. Sputum smear conversion, sputum culture conversion and chest CT scan improvement were followed up at 3, 6, 12, 18, and 24 months for bacteriological and imaging data collected. Cure rates analysed and compared in both groups.

The proportions of MDR-TB patients in the two groups achieving sputum smear/culture conversion, lung lesions absorption were assessed and compared.

Safety assessment included clinical symptom observation, Incidences of adverse event (AE )in two groups were assessed and compared. blood routine test, hematologic profile, blood biochemical examination including hepatic aminotransferase and blood ureantrogen/creatinine, blood electrolyte test (potassium, magnesium, calcium), serum thyroid stimulating hormone(TSH), audiology examinations, visual field and color examination.

Cure rate was defined as first outcome. Sputum conversion rate was defined as second outcome.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cure rate

    Completion of treatment and at least five consecutive negative sputum cultures from samples collected at least 30 days apart or one positive sputum culture followed by a minimum of three consecutive negative cultures taken at least 30 days apart during the final 12 months of treatment;

    Measured: 130 months

Secondary outcomes (1)
  1. sputum smear/culture conversion rate

    The proportions of MDR-TB patients in the two groups achieving sputum smear/culture conversion at the end of 24 months of treatment

    Measured: 24 months

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 3 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Qi Tan, PH.D (+8613584097282, aqua18345760@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cure rate (time frame: 130 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2017.
