Osimertinib + Savolitinib to Overcome Acquired MET-Mediated Resistance in Epidermal Growth Factor Receptor-Mutated, MET-Amplified Non-Small Cell Lung Cancer: TATTON.

Unlabelled: MET-inhibitor and EGFR tyrosine kinase inhibitor (EGFR-TKI) combination therapy could overcome acquired MET-mediated osimertinib resistance. We present the final phase Ib TATTON (NCT02143466) analysis (Part B, n = 138/Part D, n = 42) assessing oral savolitinib 600 mg/300 mg once daily (q.d.

Osimertinib plus Selumetinib in EGFR-Mutated Non-Small Cell Lung Cancer After Progression on EGFR-TKIs: A Phase Ib, Open-Label, Multicenter Trial (TATTON Part B).

Background: MEK/ERK inhibition can overcome acquired resistance to osimertinib in preclinical models. Osimertinib [EGFR-tyrosine kinase inhibitor (TKI)] plus selumetinib (MEK1/2 inhibitor) was assessed in the global TATTON study.

Methods: This multicenter, open-label, phase Ib study expansion cohort enrolled patients (aged ≥18 years) with MET-negative, EGFRm advanced NSCLC who had progressed on EGFR-TKIs.

Osimertinib Plus Durvalumab in Patients With EGFR-Mutated, Advanced NSCLC: A Phase 1b, Open-Label, Multicenter Trial.

Introduction: EGFR tyrosine kinase inhibitors (TKIs) are recommended for EGFR-mutated NSCLC treatment. EGFR activation up-regulates programmed death-ligand 1 expression and other immunosuppressive factors in NSCLC, causing immune microenvironment remodeling. Osimertinib (an EGFR TKI) plus durvalumab (programmed death-ligand 1 blockade) was evaluated in the TATTON study (NCT02143466).

Savolitinib ± Osimertinib in Japanese Patients with Advanced Solid Malignancies or EGFRm NSCLC: Ph1b TATTON Part C.

Background: Preliminary data suggest that combining savolitinib, a potent and highly selective MET-tyrosine kinase inhibitor (TKI), with osimertinib, a third-generation, irreversible, oral epidermal growth factor receptor-TKI (EGFR-TKI), may overcome MET-based resistance to EGFR-TKIs.

Objective: To investigate the safety and tolerability of savolitinib in Japanese patients with advanced solid malignancies.

Patients And Methods: In Part C of the phase Ib, multi-arm, open-label, multicenter TATTON study, two cohorts of Japanese adult patients were evaluated across six study centers in Japan.

Osimertinib plus savolitinib in patients with EGFR mutation-positive, MET-amplified, non-small-cell lung cancer after progression on EGFR tyrosine kinase inhibitors: interim results from a multicentre, open-label, phase 1b study.

Background: Preclinical data suggest that EGFR tyrosine kinase inhibitors (TKIs) plus MET TKIs are a possible treatment for EGFR mutation-positive lung cancers with MET-driven acquired resistance. Phase 1 safety data of savolitinib (also known as AZD6094, HMPL-504, volitinib), a potent, selective MET TKI, plus osimertinib, a third-generation EGFR TKI, have provided recommended doses for study. Here, we report the assessment of osimertinib plus savolitinib in two global expansion cohorts of the TATTON study.

Intravitreal ganciclovir maintenance injection for cytomegalovirus retinitis: efficacy of a low-volume, intermediate-dose regimen.

Objective: To report the clinical outcomes of highly active antiretroviral therapy (HAART)-naïve, human immunodeficiency virus (HIV)-positive patients with newly diagnosed cytomegalovirus (CMV) retinitis receiving intravitreal injections of a low-volume intermediate maintenance dose (1.0 mg/0.02 ml) of ganciclovir.

Prognostic factors for vision outcome after surgical repair of open globe injuries.

Purpose: To evaluate the factors influencing final visual outcome after surgical repair of open globe injuries.

Materials And Methods: The study was carried out at a tertiary referral eye care center in Central India. In this retrospective study, case records of 669 patients with open globe injuries were analyzed.
