Toxicon
CTCAE v6.0, ready whenever you need it.
Toxicon is a native Android reference designed for fast access to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) v6.0.
It helps clinicians and healthcare professionals find adverse-event definitions and grading criteria without navigating large documents or relying on an internet connection. Search across terms, System Organ Classes, definitions, grades, notes, and MedDRA LLT codes, then open a clear, structured view of the relevant criteria.
The complete reference is stored on the device, making Toxicon quick, private, and available wherever clinical work takes place.
Toxicon is intended as a reference tool. Clinical decisions remain the responsibility of the treating clinician and should be verified against the current official source when appropriate. CTCAE v6.0 was originally published by the National Cancer Institute. Toxicon is an independent application and is not affiliated with, endorsed by, or an official product of the National Cancer Institute. It is not a MedDRA browser.
Capabilities
A focused CTCAE reference for everyday clinical use
Toxicon turns the CTCAE v6.0 dataset into a clean, searchable mobile reference built around fast clinical lookup.
Search using familiar clinical language
Toxicon recognizes commonly used abbreviations and related terminology such as ALT, AST, ANC, Hgb, and LFT. It also handles useful word relationships, helping searches such as “polyneuropathy” surface relevant neuropathy terms.
Read grading criteria at a glance
Each term opens in a structured detail view with its definition, System Organ Class, LLT code, and grade 1–5 criteria. Distinct grade colors make severity levels easy to scan.
Browse all System Organ Classes
Explore the complete reference through its 26 System Organ Classes, see the number of terms in each category, and filter within a class to narrow the list.
Follow related CTCAE references
Navigational notes can link directly to referenced CTCAE terms, making it easier to move between related entries without starting another search.
Keep important terms close
Bookmark frequently consulted terms and find them in a dedicated favorites list. Favorites and recent searches are stored locally on the device.
Copy and share clearly formatted criteria
Copy or share a complete CTCAE entry — including its definition, LLT code, grading criteria, and notes — when the information needs to be used elsewhere.
