A pharmacokinetically (PK) and pharmacodynamically (PD) driven phase I trial of the pan-AKT inhibitor AZD5363 with expansion cohorts in PIK3CA mutant…
2015
Background: AZD5363 is a novel potent pan-AKT inhibitor (IC50of AKT1, AKT2 and AKT3 of 3, 7 and 7nM respectively) with preclinical activity across a range of models. Methods: The trial had an adaptive design that allowed changes in schedule based on toxicity, PK, and PD findings. AZD5363 was administered orally (PO) twice a day (BID). Three schedules were explored: continuous dosing (7/7), four days a week, (4/7) and two days a week (2/7). PD biomarkers including pAKT, pGSK3?, and pPRAS40 were measured by IHC in pre- and post-treatment tumor biopsies. Once a RP2D was established, two expansion cohorts of PIK3CA-mutant ER+ve breast (B) and gynecological (G) cancers were explored. Results: 47…

Antitumor activity of ipatasertib combined with chemotherapy: results from a phase Ib study in solid tumors
2020
Inhibidor d'AKT; Càncer avançat; Fase I Inhibidor de AKT; Cáncer avanzado; Fase I AKT inhibitor; Advanced cancer; Phase I Background This phase Ib study evaluated the safety, tolerability, pharmacokinetics, and preliminary efficacy of the oral AKT inhibitor ipatasertib and chemotherapy or hormonal therapy in patients with advanced or metastatic solid tumors to determine combined dose-limiting toxicities (DLTs), maximum tolerated dose, and recommended phase II doses and schedules. Patients and methods The clinical study comprised four combination treatment arms: arm A (with docetaxel), arm B [with mFOLFOX6 (modified leucovorin, 5-fluorouracil, and oxaliplatin)], arm C (with paclitaxel), and …

A phase Ib study of the Akt inhibitor GDC-0068 with docetaxel (D) or mFOLFOX-6 (F) in patients (pts) with advanced solid tumors.
2012
3021 Background: Activation of the Akt pathway is observed in multiple tumors and may contribute to chemoresistance. GDC-0068 is an ATP-competitive small molecule inhibitor of all three isoforms of Akt; in a phase Ia study, it was well tolerated with maximum tolerated dose (MTD) of 600 mg daily (21 days on/7days off) and pharmacodynamic down-regulation of Akt signaling in tumors at doses ≥100 mg. In vitro, GDC-0068 shows synergism with cytotoxic agents. This phase Ib study defines the dose limiting toxicities (DLT), MTD, safety and pharmacokinetics (PK) of GDC0068 in combination with D and F. Methods: Using a 3+3 designeligible patients (pt) with advanced/metastatic solid tumors were treat…
Impact of phospho-Akt expression on the clinical outcome and activity of gemcitabine and Akt inhibitors in pancreatic ductal adenocarcinoma
2017
Background: Pancreatic ductal adenocarcinoma (PDAC) is among the most lethal solid tumors. Despite extensive preclinical and clinical research, the prognosis of this disease has not significantly improved, with a 5-year survival rate around 7%. There is an urgent need to better understand the molecular pathology of PDAC in order to improve patient selection for current treatment options and to develop novel therapeutic strategies. The PI3K/AKT/mTOR pathway plays a crucial role in PDAC: activation of Akt is a frequent event and has been correlated to poor prognosis and resistance to chemotherapy. Against this background, effective blockage of Akt signaling can lead to programmed cell death a…
