Prophylaxis of Complications of Basic Therapy Using Naderin in Socially Significant Diseases (NADERIN-SSD)

Rationale Standard treatments for malignant neoplasms, tuberculosis, and hepatitis C may be associated with clinically important complications (e.g., cytopenias, immunosuppression, infections) that can impair treatment delivery and rehabilitation. Naderin (sodium nucleinate) was evaluated as an adjunct immunomodulatory/supportive-care approach intended to improve tolerance of basic therapy and reduce complication-related disruptions.

Study Design and Setting This was a prospective, controlled, open-label interventional study conducted at clinical sites affiliated with the Kazakh National Medical University (KazNMU), Almaty, Kazakhstan, supported by KazNMU Grant 2013. Allocation to intervention vs control was non-randomized (controlled cohort comparison).

Study Population and Groups (high-level)

A total of 75 participants with one of the following diagnostic categories were enrolled: malignant neoplasms, tuberculosis, or hepatitis C. Participants were assigned to:

• Intervention group: standard-of-care therapy for the underlying condition plus Naderin (immunocorrection).
• Control group: standard-of-care therapy without Naderin. (Condition-specific eligibility criteria and any stratification by disease category should be presented in the Eligibility Criteria and Study Design/Arms sections rather than repeated here.) Intervention (high-level description) Participants in the intervention group received Naderin (sodium nucleinate) as an adjunct to standard therapy. Key intervention specifications should be captured in the Arms/Interventions module (and/or here if not elsewhere): route, dose, frequency, timing relative to basic therapy, duration, and criteria for dose modification/discontinuation, consistent with protocol reporting standards for reproducibility 1.

Assessments and Follow-up

Participants underwent baseline and follow-up assessments during the active treatment/rehabilitation period that included:

• Hematology monitoring (e.g., WBC and lymphocyte counts; other CBC indices as applicable to the disease group and therapy).
• Clinical surveillance for infectious complications using predefined clinical criteria and documentation of antimicrobial treatment/hospitalization where relevant.
• Documentation of basic-therapy delivery (e.g., interruptions, delays, or discontinuation attributable to complications).
• Safety monitoring for adverse events temporally associated with adjunctive Naderin and with underlying disease therapy.

Outcomes (high-level; details elsewhere) The study evaluated hematologic parameters, infectious complications, treatment delivery disruption due to complications, and rehabilitation-related clinical outcomes. Outcome definitions, metrics, and time frames should be specified in the dedicated Outcome Measures section per SPIRIT guidance 1 and SPIRIT-Outcomes extension expectations for prespecification 2.

Statistical Approach (high-level) Between-group comparisons were planned using appropriate tests based on outcome type (categorical vs continuous) with a prespecified two-sided significance threshold. If subgroup analyses by disease category (neoplasm vs TB vs HCV) were planned, the analysis set and handling of multiplicity should be stated in the Statistical Analysis Plan or briefly here with a reference, consistent with SPIRIT expectations 1.

Ethics and Oversight The study received ethics approval from the Local Ethics Committee of KazNMU (Approval No. 15678). Written informed consent was obtained prior to enrollment. No data monitoring committee was constituted.
