## What is Onceva?

Onceva is a reference app for oncologists, hematologists and oncology pharmacists. It brings more than 1,000 published chemotherapy and systemic-therapy regimen versions together in one place, organized the way clinicians look for them, with doses shown as reported in the source publication, alongside references.

REGIMENS
• Browse by cancer type and treatment setting (neoadjuvant, adjuvant, first line, later lines, maintenance and more), separately for solid tumors and hematologic malignancies.
• Each regimen version shows drugs, doses, routes, administration days and cycle information as reported in the source study, with study phase, sample size, journal and year.
• Multi-phase regimens are shown phase by phase; versions that cannot be calculated are shown as written in the source.
• Search by drug, drug combination, regimen name or cancer type.

DOSE CALCULATOR
• Enter only what the regimen needs (height, weight, age, sex, serum creatinine) and get per-administration doses calculated from the source dosing, including body surface area, mg/kg and carboplatin AUC (Calvert) dosing.
• Calculator inputs are not saved in the app. Calculations are processed by our service.

LITERATURE AND CLINICAL TRIALS (free)
• A home feed of recent oncology publications and recruiting clinical trials, sorted by date.
• Open any item to read its abstract or trial details.

MEDICAL TOOLS (free)
• Calculators for BSA, creatinine clearance and carboplatin dose, BMI, ideal body weight, and ECOG / Karnofsky performance status.
• Adverse event grading (CTCAE) and response assessment criteria.

Full regimen versions and the dose calculation for each regimen are available with Basic Unlock, a one-time purchase (not a subscription). Everything else is free: the home feed of publications and clinical trials, the medical tools, CTCAE grading and response criteria.

CONTENT: Regimen, dose, schedule, trial and drug-summary content was compiled with AI assistance from published sources; each record cites its source. Source checks are AI-assisted and ongoing; errors can remain. Verify against the original source before any clinical decision.

IMPORTANT: Onceva is intended for healthcare professionals as a reference only. It does not provide medical advice, diagnosis or treatment recommendations. Always verify doses against the original publication, product labeling and your institution's protocols, and use clinical judgment for each patient.
