PURPOSE: This phase I study assessed the maximum tolerated dose (MTD), dose-limiting toxicities (DLT), safety, pharmacokinetics, pharmacodynamics, and clinical activity of the first-in-class dual MEK/RAF inhibitor, RO5126766. EXPERIMENTAL DESIGN: Initial dose-escalation was conducted using once daily dosing over 28 consecutive days in 4-week cycles. Further escalation was completed using 2 intermittent dosing schedules [7 days on treatment followed by 7 days off (7on/7off); 4 days on treatment followed by 3 days off (4on/3off)]. RESULTS: Fifty-two patients received RO5126766 at doses of 0.1 to 2.7 mg once daily, 2.7 to 4.0 mg (4 on/3 off), or 2.7 to 5.0 mg (7 on/7 off). The most common DLTs were elevated creatine phosphokinase (CPK) and blurred vision. The MTD for each dosing schedule was 2.25 mg once daily, 4.0 mg (4 on/3 off), and 2.7 mg (7 on/7 off). The dose/schedule recommended for phase II (RP2D) investigation was 2.7 mg (4 on/3 off). Frequent adverse events included rash-related disorders (94.2%), elevated CPK (55.8%), and diarrhea (51.9%). C(max) occurred 1 to 2 hours after dosing and mean terminal half-life was approximately 60 hours. Pharmacodynamic changes included reduced ERK phosphorylation, an increase in apoptosis in tumor tissue, and a reduction in fluorodeoxyglucose (FDG) uptake after 15 days of dosing. Three partial responses were seen: two in BRAF-mutant melanoma tumors and one in an NRAS-mutant melanoma. CONCLUSION: This first-in-human study shows that oral RO5126766 has manageable toxicity, a favorable pharmacokinetic/pharmacodynamic profile, and encouraging preliminary antitumor activity in this population of heavily pretreated patients, achieving tumor shrinkage in around 40% of patients across all dose levels and all tumor types.

Lessons Learned
- The overall safety profiles of ipilimumab 3 mg/kg and 10 mg/kg administered every 3 weeks, were consistent between Chinese patients with solid tumors in the current study and patients from previous U.S. ipilimumab monotherapy studies. No new safety signals were identified.
- The mean systemic exposures to ipilimumab (assessed by first dose area under the curve during the dosing interval and maximum serum concentration) were numerically lower in the Chinese patient population than in U.S. patients for both 3 mg/kg and 10 mg/kg doses; however, the range of serum concentrations in the Chinese and U.S. populations overlapped (3 mg/kg and 10 mg/kg), suggesting that ipilimumab pharmacokinetics was ethnically insensitive in this study.

Introduction
PTK/ZK is a small-molecule inhibitor of all three vascular endothelial growth factor (VEGF) receptors, platelet-derived growth factor receptor, colony-stimulating factor 1 receptor, and cytokine stem cell factor receptor. Cetuximab is a monoclonal antibody against epidermal growth factor (EGF) receptor. Combining inhibition of VEGF and EGF signaling might act additive or synergistically.Methods
In phase 1 design, patients with advanced solid tumors were treated with PTK/ZK daily (cohort 1, 750 mg once daily; cohort 2, 1250 mg once daily; cohort 3, 250 mg [morning] and 500 mg [evening]; and cohort 4, 500 mg [morning] and 750 mg [evening]) in combination with cetuximab 250 mg/m2 weekly in cycles of 28 days in cohorts of three patients. Toxicity was evaluated conform the Common Terminology Criteria for Adverse Events classification 3.0. Pharmacokinetics and pharmacodynamics consisting of circulating endothelial (progenitor) cell (CE[P]C) analysis by flow cytometry were performed.Results
Safety and tolerability was evaluated in 16 patients. The most frequently reported adverse events were acne, dry skin, fatigue, nausea, dizziness, vomiting, headache, and diarrhea. One dose-limiting toxicity occurred in cohort 3 consisting of a grade 3 transaminitis. Pharmacokinetic analysis revealed no significant changes in PTK/ZK exposure on coadministration with cetuximab and in bioavailability at equivalent total daily doses. Biomarker analysis showed no significant change in the number of CE(P)Cs during treatment. One of 14 evaluable patients showed a partial response for at least 11.5 months, and 7 patients (50%) stable disease for at least 2 months.Conclusions
This study shows that the combination of PTK/ZK and cetuximab is well tolerated with only slightly overlapping toxicity profiles and has antitumor activity. 相似文献6.
Background
BRAF mutations are a validated target for cancer therapy. A second-generation BRAF inhibitor with an improved preclinical safety profile (RG7256) was evaluated in a first-in-man study in order to determine the safety, efficacy, pharmacokinetics and pharmacodynamics in patients with BRAF V600-mutated advanced solid tumors.Patients and Methods
Patients received RG7256 orally over 8 dose levels from 200 mg once a day (QD) to 2400 mg twice a day (BID) (50-, 100- and 150-mg tablets) using a classic 3?+?3 dose escalation design.Results
In total, 45 patients were enrolled; most (87 %) had advanced melanoma (94 % BRAF V600E). RG7256 was rapidly absorbed, with limited accumulation and dose-proportional increase in exposure up to 1950 mg BID. The maximal tolerated dose (MTD) was not reached. The most common drug-related adverse events (AEs) were dyspepsia (20 %), dry skin (18 %), rash (18 %), fatigue (16 %) and nausea (13 %), mainly grade 1. Three patients (7 %) developed cutaneous squamous cell carcinoma. Photosensitivity, arthralgia and increased liver enzyme levels were each observed in only one patient each. Of 44 evaluable patients, 14 (32 %) had a partial response (melanoma and thyroid cancer). At high dose levels (>1200 mg BID), 10 of 16 (63 %) patients had a partial response. A decrease in maximum standardized uptake value (SUVmax) on FDG-PET of ≥25 % was observed in 19 of 37 patients. On-treatment reductions in pERK were documented in eight of ten paired tumor samples.Conclusions
RG7256 has a favorable safety profile compared to other BRAF inhibitors while maintaining clinical activity, and MTD was not reached. The excessive pill burden needed to provide the desired exposure, and thus concerns about patient compliance, limited further development of this agent.Study Identifier: ClinicalTrials.gov (NCT01143753)

IntroductionThis first-time-in-humans study assessed the safety, pharmacokinetics (PK), pharmacodynamics (PD), and clinical activity of GSK2879552 in patients with relapsed or refractory SCLC.MethodsThis phase I, multicenter, open-label study (NCT02034123) enrolled patients (≥18 years old) with relapsed or refractory SCLC (after ≥1 platinum-containing chemotherapy or refusal of standard therapy). Part 1 was a dose-escalation study; Part 2 was a dose-expansion study. Dose escalations were based on safety, PK, and PD. The primary end point (Part 1) was to determine the safety, tolerability, and recommended dose and regimen of GSK2879552. Secondary end points were to characterize PK and PD parameters and measure disease control rate at week 16. Part 2 was not conducted.ResultsBetween February 4, 2014, and April 18, 2017, a total of 29 patients were allocated to one of nine dose cohorts (0.25 mg–3 mg once daily and 3-mg or 4-mg intermittent dosing). In all, 22 patients completed the study; 7 withdrew, primarily owing to adverse events (AEs). Most patients (24 of 29 [83%]) had at least one treatment-related AE, most commonly thrombocytopenia (12 of 29 [41%]). Twelve serious AEs (SAEs) were reported by nine patients; six were considered treatment related, the most common of which was encephalopathy (four SAEs). Three patients died; one death was related to SAEs. PK was characterized by rapid absorption, slow elimination, and a dose-proportional increase in exposure.ConclusionsGSK2879552 is a potent, selective inhibitor of lysine demethylase 1A and has demonstrated favorable PK properties but provided poor disease control and a high AE rate in patients with SCLC. The study was terminated, as the risk-benefit profile did not favor continuation. 相似文献

BackgroundSavolitinib has shown good tolerability and preliminary efficacy, but efficacy biomarkers require investigation. The main purpose of this study was to confirm in Chinese patients the recommended phase II dose (RP2D) of savolitinib and to explore overall benefit in tumors bearing c-Met aberration.MethodsThis was an open-label, multi-center, 2-part phase I study. A starting dose of 600 mg QD was initiated in the escalation phase, utilizing a 3+3 design with repeated QD and BID dosing. In the dose expansion phase, we enrolled patients with gastric cancer and non–small cell lung cancer (NSCLC) with documented c-met aberration into 5 cohorts to further explore biomarkers. c-Met overexpression and amplification were assessed by immunohistochemistry and FISH, respectively.ResultsThe safety analysis set included 85 patients. Only one dose-limiting toxicity (grade 3 fatigue) was reported in the 600 mg BID dosing group. The most frequent treatment-related adverse events were nausea (29.4%), vomiting (27.1%), and peripheral edema (21.2%). Notably, in gastric cancer, response was only observed in patients with MET amplification (copy number 9.7-18.4), with an objective response rate of 35.7% and a disease control rate of 64.3%. For patients with NSCLC bearing a MET exon 14 skipping mutation, obvious target lesion shrinkage was observed in 2 of 4 patients, although PR was not achieved.ConclusionThe RP2D of savolitinib was established as 600 mg QD or 500 mg BID in Chinese patients. The promising response observed in patients with gastric cancer with c-met amplification and NSCLC with MET exon 14 skipping mutation warrants further investigation.ClinicalTrials.gov IdentifierNCT0198555 相似文献

Src is overexpressed in various cancers, including 27% of non-small cell lung cancer NSCLC, and is correlated with poor clinical outcomes. We hypothesize that Src kinase inhibitors, including Bosutinib, may exhibit clinical synergy in combination with the antifolate drug pemetrexed. In this Phase I, dose-escalation, safety, and maximum tolerated dose (MTD)-determining study, 14 patients with advanced metastatic solid tumors that had progressed on “standard of care” chemotherapy were enrolled in a 3 + 3 dose escalation study. Oral Bosutinib was administered once daily beginning on day 1, where the first cohort started at an oral dose of 200 mg daily with pemetrexed 500 mg/m2 IV on a three-week schedule. The study’s primary objective was to determine the dose-limiting toxicity (DLT), the MTD of Bosutinib in combination with pemetrexed, and the type and frequency of adverse events associated with this treatment. Twelve patients were evaluable for response, including ten patients with adenocarcinoma of the lung, one patient with metastatic adenocarcinoma of the appendix, and one patient with urothelial carcinoma. The median number of Bosutinib and pemetrexed cycles received was 4 (range, 1–4). The MTD of oral Bosutinib in this combination was 300 mg daily. Two patients (17%) had a partial response (PR), and seven patients (58%) showed stable disease (SD) as the best response after the fourth cycle (end of treatment). One patient had disease progression after the second cycle, while three patients had disease progression after the fourth cycle. The two responders and the two patients with the longest stable disease duration or stabilization of disease following progression on multiple systemic therapies demonstrated Src overexpression on immunohistochemical staining of their tumor. The median progression-free survival (PFS) was 6.89 months (95% CI (3.48, 30.85)), and the median overall survival (OS) was 11.7 months (95% CI (3.87, 30.85)). Despite the limitations of this Phase I study, there appears to be potential efficacy of this combination in previously treated patients. 相似文献

IntroductionRezivertinib (BPI-7711) is a novel third-generation EGFR tyrosine kinase inhibitor selective for EGFR-sensitizing and T790M mutations. This study was designed to evaluate the safety, efficacy, and pharmacokinetics of rezivertinib for patients having advanced NSCLC with EGFR T790M mutation.MethodsThis phase 1 study (NCT03386955) was conducted across 20 sites in the People's Republic of China. Patients received rezivertinib at six oral dose levels (30 mg, 60 mg, 120 mg, 180 mg, 240 mg, 300 mg) once daily until disease progression, unacceptable toxicity, or patient withdrawal. The primary end points were safety for the dose-escalation phase and objective response rate by the blinded independent central review for the total study population.ResultsA total of 19 patients in dose-escalation phase using the standard 3 + 3 design principle and 153 patients in dose-expansion phase were enrolled from September 11, 2017, to August 23, 2019. The data cutoff date was on June 15, 2020. No dose-limiting toxicity occurred in the dose-escalation phase. The treatment-related adverse events were observed in 82.0% (141 of 172) of patients, and 17.4% (30 of 172) had grade greater than or equal to 3, among which decreased neutrophil count (2.9%), leukopenia (2.9%), and pneumonia (2.9%) were the most common. The overall blinded independent central review–evaluated objective response rate was 59.3% (102 of 172, 95% confidence interval: 51.6–66.7), and the median progression-free survival was 9.7 (95% confidence interval: 8.3–11.1) months.ConclusionsRezivertinib was found to have promising efficacy with a manageable safety profile in patients with EGFR T790M-mutated advanced NSCLC. Further study is warranted. 相似文献
