Richtig - die Immuntherapien sind alle ähnlich, aber manche haben Beschränkungen z.B. bei bestimmten Genmutationen. Der Arzt ärgert sich, dass er die ganzen Mutationen in einer Tabelle nachschlagen muss, um richtig zu verschreiben, wenn er keinen Ärger riskieren will.
"limited range of approved uses" ist der gewünschte Ausdruck, denn prompt fällt mir ein, Ähnliches kürzlich in einem lawsuit der FDA gegen illegale Pharmawerbung gelesen zu haben. Hätte ich auch selbst drauf kommen können. Bin ich aber nicht. Ah well.
'Restriced approval' oder 'approval with restrictions' ist übrigens auch geläufig, bezieht sich aber nicht ausschließlich auf das Anwendungsgebiet und scheint sich meist auf Fälle wie accelerated approvals zu beziehen, bei denen das Produkt noch nicht komplett wissenschaftlich untermauert ist.
Cf. Accelerated and Restricted Approvals Under Subpart H (drugs) and Subpart E (biologics)
R - Restricted - Approval with restrictions to assure safe use as recorded in 21 CFR 601.42 (Subpart E).

§ 601.42 Approval with restrictions to assure safe use.
(a) If FDA concludes that a biological product shown to be effective can be safely used only if distribution or use is restricted, FDA will require such postmarketing restrictions as are needed to assure safe use of the biological product, such as:
(1) Distribution restricted to certain facilities or physicians with special training or experience; or
(2) Distribution conditioned on the performance of specified medical procedures.

If regulators judge the magnitude of uncertainty to be such that it precludes regular approval, they may grant approval under a special pathway (AA in the United States or CMA in the EU) but impose postmarketing study obligations to address critical knowledge gaps as described earlier. Regulators may also restrict the approved indication to a specific subset of the studied population for which more robust evidence exists. Alternatively, regulators may decide there is insufficient evidence to support either regular, special, or some form of restricted approval, and refuse marketing authorization.

We welcome the opportunity to provide some additional detail regarding our definition of “restricted approval,” which is defined as medicines that are approved in a restricted subpopulation (as opposed to the full indication as part of the application).
