Main Lithuania-specific differences

Lithuanian is the working language for the national Part II package

The Lithuanian Bioethics Committee states that the Part II documents in its national recommendations must be submitted in Lithuanian. This is especially important for participant-facing information and consent documents, recruitment materials and national Part II forms. English source documents can still be useful for global drafting, but the Lithuania submission package should be built around the Lithuanian versions required for Part II. The Lithuania Part II document checklist maps the national document set.

Lithuania publishes a national Part II list and sample forms

The Lithuanian Bioethics Committee's national recommendations cover recruitment and informed consent procedures, participant information, investigator suitability, declarations of interest, site suitability, insurance, financial arrangements, proof of payment, GDPR compliance and biological samples. The sample forms in the national recommendations are described as recommended rather than mandatory, so a different format can be acceptable if it fully covers the required information.

Minors have specific national consent and assent rules

Lithuania normally requires consent from both parents for a child's participation, subject to defined exceptions. National Part II guidance also distinguishes children under 12 from those aged 12 and above. From age 12, the child should receive information orally and in writing and, when capable of understanding it, sign an assent form. The Lithuania minor consent and assent guide explains the practical document set.

Secondary and future use should remain optional

The Lithuanian Bioethics Committee recommends either a separate informed consent form for future use of biological samples and coded data or a separate opt-in choice in the consent section. Future use should not be presented as a condition of joining the main trial. The Lithuania secondary-use consent guide covers the recommended structure.
