The Record... (cont'd)

Ric,
That's a great way to get the literature references. Thanks for thinking of it.

I also understand that Adis does some evaluative ratings on drugs. What criteria do they use? Can you get me their ratings on vatalanib?

Sharon

I'm glad Sharon asked about the way Adis does its rating.

Adis has developed a highly structured system to provide a rating guide for the clinical potential of new agents undergoing research and development. Compounds of commercial interest have been rated on their likely therapeutic potential by the Adis editorial staff.

The system is based on the assignment of a numerical score of up to 20 key evaluation criteria. The ratings are derived from the literature available at the time the evaluation is undertaken. The Evaluation is added as soon as there is sufficient published information to allow a Rating to be derived. It is unlikely that this will be at the time when a record is first established.

Ratings for compounds can be one of five types: Preclinical rating: chemistry and pharmacodynamics, Clinical pharmacokinetics rating, Clinical efficacy and use rating, Clinical Safety, and Clinical outcome and pharmacoeconomic, depending upon the information available which, in turn, is generally related to the phase of development of a compound.

The Adis editors rate compounds in late-stage development, (e.g. phase II/III, III) preregistration, and provides associated commentary.

The degree of certainty in the Adis rating will depend on the number of criteria evaluated in light of currently available information. Ratings are updated as new information is published in the literature.

Ratings are specific to a particular indication and/or route of administration (or dosage form). Thus, a drug may have multiple, different ratings.

A drug is initially evaluated for the main disease for which it is indicated; as further indications are reported, additional evaluations can be added. Expand on the EV= field for a list of disease terms.

Criteria evaluated to generate an Adis Therapeutic Rating:

Rating Criteria
Preclinical – chemistry & pharmacodynamics chemical structure (novelty); mechanism of action (novelty), specificity of action, stability to inactivation, selectivity, secondary pharmacological properties, toxicity in animal studies, pharmacokinetic attributes
Clinical – Pharmacokinetics bioavailability, linear kinetics, interindividual variability, formation of active metabolites, effects of renal or hepatic dysfunction
Clinical – Clinical efficacy & use convenience of administration; dose administration frequency; relative efficacy against indicated disease
Clinical – Safety Adverse effects; contraindications/precautions, drug interaction potential
Clinical – Clinical outcome & pharmacoeconomic considerations Clinical outcome; direct/acquisition cost; potential economic benefits (indirect cost savings)

To search for products in Phase II or III clinical trials that are indicated for Alzheimer's disease and have an Adis therapeutic value rating of 70 or higher, use the following command summary:

Example:
B 107
S alzheimer?(s)(ii or iii)/st
S s1 and sc>=70
T s2/3,sc/1
