First-in human, phase 1, dose-escalation pharmacokinetic and pharmacodynamic study of the oral dual PI3K and mTORC1/2 inhibitor PQR309 in patients with advanced solid tumors (SAKK 67/13)
BACKGROUND: PQR309 is an orally bioavailable, balanced pan-phosphatidylinositol-3-kinase (PI3K), mammalian target of rapamycin (mTOR) C1 and mTORC2 inhibitor. PATIENTS AND METHODS: This is an accelerated titration, 3 + 3 dose-escalation, open-label phase I trial of continuous once-daily (OD) PQR309 administration to evaluate the safety, pharmacokinetics (PK) and pharmacodynamics in patients with advanced solid tumours. Primary objectives were to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). RESULTS: Twenty-eight patients were included in six dosing cohorts and treated at a daily PQR309 dose ranging from 10 to 150 mg. Common adverse events (AEs; ≥30% patients) included fatigue, hyperglycaemia, nausea, diarrhoea, constipation, rash, anorexia and vomiting. Grade (G) 3 or 4 drug-related AEs were seen in 13 (46%) and three (11%) patients, respectively. Dose-limiting toxicity (DLT) was observed in two patients at 100 mg OD (>14-d interruption in PQR309 due to G3 rash, G2 hyperbilirubinaemia, G4 suicide attempt; dose reduction due to G3 fatigue, G2 diarrhoea, G4 transaminitis) and one patient at 80 mg (G3 hyperglycaemia >7 d). PK shows fast absorption (Tmax 1-2 h) and dose proportionality for Cmax and area under the curve. A partial response in a patient with metastatic thymus cancer, 24% disease volume reduction in a patient with sinonasal cancer and stable disease for more than 16 weeks in a patient with clear cell Bartholin's gland cancer were observed. CONCLUSION: The MTD and RP2D of PQR309 is 80 mg of orally OD. PK is dose-proportional. PD shows PI3K pathway phosphoprotein downregulation in paired tumour biopsies. Clinical activity was observed in patients with and without PI3K pathway dysregulation. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov # NCT01940133
Fifteen-year trends in metastatic breast cancer survival in Greece
In the metastatic setting, a detected time trend to improved prognosis could be attributed to the corresponding recent advances in the therapeutic approaches. The aim of the current study was to first assess, in a large cohort of well over a thousand patients, the time trends in survival in MBC for the last 15 years and second to explore its association to prognostic factors affecting outcome including therapeutic regimen. This meta-analysis uses individual patient data collected from all the trials on MBC (6 nonrandomized, 4 randomized) conducted by HeCOG from 1991 through 2006. Four 4-year time periods (1991-1994, 1995-1998, 1999-2002, and 2003-2006) were constructed for exploration of time trends in survival according to the patient's date of metastatic diagnosis. Different first line regimens in the 10 trials include anthracycline monotherapy (epirubicin, in the early 1990s) and taxane-containing regimens either as monotherapy or in different combinations with anthracyclines or other drugs. In two phase II studies and in the last randomized study, trastuzumab was administered in all the patients with HER2 overexpressing tumors. In this study, information is based on a total of 1361 patients with a median follow up of 3.7 years and median survival of 1.9 years (median survival 1.28, 1.68, 2.20, and 2.57 years for 1991-1994, 1995-1998, 1999-2002, and 2003-2006, respectively). Survival improved significantly across diagnosis time periods, by 25, 44, and 51%, respectively, in each time period (1995-1998: HR = 0.75, P = 0.004; 1999-2002: HR = 0.56, P < 0.001; 2003-2006: HR = 0.49, P < 0.001) as compared to the first time period (1991-1994). The effect of metastatic diagnosis time period remains almost unchanged in the presence of the following significant prognostic factors: performance status, hormonal receptor status, previous adjuvant chemotherapy, previous adjuvant hormonal treatment, visceral metastasis at entry, and number of metastatic sites. When exploring the effect of new systemic treatment introduction, taking into account the same significant prognostic factors, the effect of diagnosis time period disappears, and the survival improvement is explained directly by the introduction of new agents (hormonal treatment for metastatic disease: yes vs. no: HR = 0.72, P < 0.001; taxanes at first line: yes vs. no: HR = 0.69, P = 0.002; trastuzumab at first line: yes vs. no: HR = 0.63, P < 0.001). The results of this study provide significant evidence of improvement in prognosis of MBC patients within the last 15 years, taking into account all the important significant prognostic factors, and this improvement can be attributed to the use of new systemic treatment agents in the management of the disease. © 2009 Springer Science+Business Media, LLC

The Glasgow Prognostic Score (GPS) predicts toxicity and efficacy in platinum-based treated patients with metastatic lung cancer
Purpose: Lung cancer is the most common cause of cancer death. A cumulative prognostic score based on C-reactive protein and albumin, termed the Glasgow Prognostic Score (GPS), indicates the presence of systemic inflammatory response. GPS has been proposed as a powerful prognostic tool for patients with various types of malignant tumors, including lung cancer. The aim of this study was to assess the predictive value of baseline GPS in terms of toxicity and response in lung cancer patients treated with platinum-based chemotherapy. Patients and methods: Patients referred to our institution for consideration of first-line platinum-based treatment were eligible. Demographics and disease-related characteristics were recorded. Toxicity was graded according to NCI CTCAE version 3.0 throughout first-line therapy. GPS was calculated before the onset of treatment and was related to the development of toxicity. Response to first-line therapy and survival data were also collected. Results: Totally, 96 lung cancer patients were accrued. GPS was associated with increased mucositis p = 0.004), neurotoxicity (p = 0.038), neutropenia (p =0.02), dose reductions or/ and need for granulocyte colony-stimulating factor (G-CSF) support (p=0.005), toxicity-related termination of treatment (p=0.001) and chemotherapy-related toxic deaths (p=0.013). GPS was associated with overall survival (p=0.016) and progression-free survival (p=0.016) as well as response to treatment (p=0.05). Conclusions: Our data demonstrate that GPS assessment is predictive of the most important aspects of platinum-related toxicity and this may partly explain its associations with poor clinical outcome in patients with metastatic lung cancer.
