WebDec 18, 2002 · The primary or third-order aberrations represent the basic principles of aberration theory. The Zernike polynomials can be used to describe the wave aberration of an optical system for a chosen field. Webaberrations, we investigate preliminary safety, PK, and efficacy. Methods: Pts were enrolled by a 3+3 design and treated with L (15-20 mg QD) + M (2-4 mg QD or BID) across 9 dose levels (DLs). Primary objectives were to evaluate safety/tolerability, estimate MTD, and identify recommended Phase 2 dose (RP2D). Tumor
