- Background: Prior pilot studies support the use of antiviral medications with topical corticosteroids for herpes simplex labialis (HSL). ME-609 (Xerese, Xerclear) is a combination of 5% acyclovir and 1% hydrocortisone developed for the topical treatment of HSL. Objectives: The primary study end point was the prevention of ulcerative HSL lesions. Methods: In all, 2437 patients with a history of HSL were randomized to self-initiate treatment with ME-609, 5% acyclovir in ME-609 vehicle, or ME-609 vehicle (placebo) at the earliest sign of a cold sore recurrence. Cream was applied 5 times/d for 5 days. A total of 1443 patients experienced a recurrence and initiated treatment with ME-609 (n = 601), acyclovir (n = 610), or placebo (n = 232). Results: Of patients receiving ME-609, 42% did not develop an ulcerative lesion compared with 35% of patients receiving acyclovir in ME-609 vehicle (P = .014) and 26% of patients receiving placebo (P < .0001). In patients with ulcerative lesions, healing times were reduced in the ME-609 and acyclovir groups compared with placebo (P < .01 for both). The cumulative lesion area for all lesions was reduced 50% in patients receiving ME-609 compared with the placebo group (P < .0001). There were no differences among groups in the number of patients with positive herpes simplex virus cultures. The side-effect profile was similar among treatments. Limitations: The study did not contain a group treated with a topical corticosteroid alone. Conclusions: ME-609 prevented progression of cold sores to ulcerative lesions and significantly reduced the cumulative lesion area compared with acyclovir and placebo. ME-609 treatment offers additional therapeutic benefit compared with therapy with topical acyclovir alone. (J Am Acad Dermatol 2011;64:696-705.)

- Purpose Melflufen (melphalan flufenamide, previously designated J1) is an optimized and targeted derivative of melphalan, hydrolyzed by aminopeptidases overexpressed in tumor cells resulting in selective release and trapping of melphalan, and enhanced activity in preclinical models. Methods This was a prospective, single-armed, open-label, first-in-human, dose-finding phase I/IIa study in 45 adult patients with advanced and progressive solid tumors without standard treatment options. Most common tumor types were ovarian carcinoma (n = 20) and non-small-cell lung cancer (NSCLC, n = 11). Results In the dose-escalating phase I part of the study, seven patients were treated with increasing fixed doses of melflufen (25-130 mg) Q3W. In the subsequent phase IIa part, 38 patients received in total 115 cycles of therapy at doses of 30-75 mg. No dose-limiting toxicities (DLTs) were observed at 25 and 50 mg; at higher doses DLTs were reversible neutropenias and thrombocytopenias, particularly evident in heavily pretreated patients, and the recommended phase II dose (RPTD) was set to 50 mg. Response Evaluation Criteria In Solid Tumors (RECIST) evaluation after 3 cycles of therapy (27 patients) showed partial response in one (ovarian cancer), and stable disease in 18 patients. One NSCLC patient received nine cycles of melflufen and progressed after 7 months of therapy. Conclusions In conclusion, melflufen can safely be given to cancer patients, and the toxicity profile was as expected for alkylating agents; RPTD is 50 mg Q3W. Reversible and manageable bone marrow suppression was identified as a DLT. Clinical activity is suggested in ovarian cancer, but modest activity in treatment of refractory NSCLC.

- BACKGROUND: The primary objective of this study was to compare the progression-free survival (PFS) at 12 weeks between patients treated with IGF-1R pathway modulator AXL1717 (AXL) and patients treated with docetaxel (DCT).MATERIAL AND METHODS: The study was conducted at 19 study centers in five countries. A total of 99 patients with previously treated, locally advanced or metastatic non-small cell lung cancer (NSCLC) of the squamous cell carcinoma (SCC) or adenocarcinoma (AC) subtypes in need of additional treatment were randomized and treated with either 300 or 400 mg of AXL as daily BID treatment (58 patients) or DCT given as 75 mg/m(2) in three-week cycles (41 patients) as monotherapy in a 3:2 ratio for each NSCLC subtype. Patients were treated in the primary study treatment period for a maximum of four treatment cycles.RESULTS: The 12-week PFS rate, median PFS and overall survival (OS), as well Kaplan-Meier hazard ratio for PFS and OS, did not show any statistically significant differences between the treatment groups. For the primary endpoint, the AXL group had a lower percentage of patients (25.9%) who were progression-free at Week 12 as compared to the DCT group (39.0%), although the difference was not statistically significant. The most notable difference in the incidence of treatment emergent adverse effects (TEAEs) was the lower incidence of treatment-related grade 3/4 neutropenia in patients treated with AXL.CONCLUSION: These results suggest neither of the treatments to be superior of the other when treating locally advanced or metastatic NSCLC. Considering the lower incidence of grade 3/4 neutropenia in the AXL group this treatment warrants further research.

- BACKGROUND: A phase Ia/b dose-escalation study was performed to characterize the safety, efficacy and pharmacokinetic properties of the oral small molecule insulin-like growth factor-1-receptor pathway modulator AXL1717 in patients with advanced solid tumors.MATERIAL AND METHODS: This was a prospective, single-armed, open label, dose-finding phase Ia/b study with the aim of single day dosing (phase Ia) to define the starting dose for multi-day dosing (phase Ib), and phase Ib to define and confirm recommended phase II dose (RP2D) and if possible maximum tolerated dose (MTD) for repeated dosing.RESULTS AND CONCLUSION: Phase Ia enrolled 16 patients and dose escalations up to 2900 mg BID were successfully performed without any dose limiting toxicity (DLT). A total of 39 patients were treated in phase Ib. AXL1717 was well tolerated with neutropenia as the only dose-related, reversible, DLT. RP2D dose was found to be 390 mg BID for four weeks. Some patients, mainly with NSCLC, demonstrated signs of clinical benefit, including four partial tumor responses (one according to RECIST and three according to PET). The 15 patients with NSCLC with treatment duration longer than two weeks with single agent AXL1717 in third or fourth line of therapy showed a median progression-free survival of 31 weeks and overall survival of 60 weeks. Down-regulation of IGF-1R on granulocytes and increases of free serum levels of IGF-1 were seen in patients treated with AXL1717. AXL1717 had an acceptable safety profile and demonstrated promising efficacy in this heavily pretreated patient cohort, especially in patients with NSCLC. RP2D was concluded to be 390 mg BID for four weeks. Trial number is NCT01062620.

- Background. Inhibition of the Insulin-like Growth Factor-1 receptor (IGF-1R) has resulted in extensive anti-tumor effects. Picropdophyllin (PPP, AXL1717) is a small-molecule inhibitor of the IGF-1R without inhibition of closely related receptors including the insulin receptor and has shown extensive effects against a wide range of tumors in animals. PPP is currently tested as an orally administrated single agent treatment in an open-label combined Phase I/II clinical study in advanced cancer patients with solid tumors which progress in spite of several lines of treatment. Patients and methods. The first part (Phase IA) consisted of single day BID dosing every three weeks with consecutive dose escalations. The second part (Phase IB) consists of seven days or longer BID dosing every three weeks, dosing range being 520-700 mg BID. Non-progressing patients could continue treatment within a compassionate use setting. Results and discussion. The present report describes our experience with the four patients with progressive squamous non-small cell lung cancer (NSCLC) that have received treatment with PPP. Despite more than seven months of PPP treatment as third or fourth line treatment, the reported patients did not develop any additional metastases. Furthermore, CT scans as well as (18)FDG-Positron Emission Tomography (PET) scans of the patients demonstrated large central necrotic areas, which may suggest tumor response. At the same time, the study drug is so far well tolerated. The phenomenon of necrosis in the tumors suggestive of tumor response has not been reported before in anti-IGF-1R treatment and will be subject to further studies in the present clinical trial.

- AXL1717 is an orally bioavailable IGF-1R pathway modulator that has been shown to have anti-tumoral effects. The objectives of the present study were to define maximum tolerated dose and the recommended phase II dose (RPTD) of AXL1717 in combination with gemcitabine HCl and carboplatin in non-small cell lung cancer (NSCLC). Patients with previously untreated, locally advanced, or metastatic NSCLC (squamous cell cancer or adenocarcinoma) in good performance status and with preserved major organ functions were enrolled in the study. The study was an open-label phase I study with planned cohorts of three patients per dose level of AXL1717 (215, 290, and 390 mg BID). In total, 12 patients were enrolled in the study, and of these, two were prematurely excluded. AXL1717 was administered at one dose level, 215 mg BID. A total number of 81 unique adverse events were reported. Bone marrow toxicity was reported in 10 out of 12 patients, and this organ class showed the largest number of related events. AXL1717 in combination with gemcitabine HCl and carboplatin is a possible treatment approach in previously untreated, locally advanced, or metastatic non-small cell lung cancer. However, due to the bone marrow toxicity profile shown in the present study, further dose increases of AXL1717 above 215 mg BID will probably not be feasible. Therefore, 215 mg BID constitutes maximum tolerated dose and RPTD.

- Background: The aim of the present study was to investigate any prognostic value of pre-treatment anemia, leukocytosis and thrombocytosis in patients with advanced pretreated NSCLC.Methods: A randomized, multicenter phase II study comparing the IGF-1R modulator AXL with standard docetaxel in the treatment of previously treated stage IIIB or IV NSCLC patients was conducted in 2011-2013. Clinical and laboratory data were collected, including serum values for hemoglobin (Hgb), white blood cells (WBC) and platelets (Plt) at baseline. These hematological parameters were studied in relation to overall survival using Kaplan-Meier product-limit estimates and multivariate Cox proportional hazards regression models.Results: The median overall survival for all patients was 8.9 months. Patients with leukocytosis (WBC > 9 x 109/L) had a significantly shorter median overall survival (4.2 months) as compared with those with a WBC ≤ 9 x 109/L at baseline (12.3 months) with a corresponding of HR 2.10 (95% CI: 1.29-3.43). Patients with anemia (Hgb < 110 g/L) had a non-significant (p = 0.097) shorter median overall survival (6.1 months) as compared with their counterparts with Hgb ≤ 110 g/L at baseline (9.4 months). As for thrombocytosis (Plt > 350 x 109/L), there was no statistically significant impact on overall survival. Leukocytosis retained its prognostic significance in a multivariate model where other clinical factors such as age, sex and WHO performance status were taken into consideration (HR: 1.83, 95% CI: 1.06-3.13, p = 0.029).Conclusion: Pre-treatment leukocytosis is a strong and independent prognostic marker for shorter overall survival in previously treated stage IIIB or IV NSCLC patients receiving docetaxel or AXL1717. Combined use of pre-treatment leukocytosis assessments together with established prognostic factors such as performance status could be of help when making treatment decisions in this clinical setting.

- The driving force behind oncoproteomics is to identify protein signatures that are associated with a particular malignancy. Here, we have used a recombinant scFv antibody microarray in an attempt to classify sera derived from pancreatic adenocarcinoma patients versus healthy subjects. Based on analysis of nonfractionated, directly labeled, whole human serum proteomes we have identified a protein signature based on 19 nonredundant analytes, that discriminates between cancer patients and healthy subjects. Furthermore, a potential protein signature, consisting of 21 protein analytes, could be defined that was shown to be associated with cancer patients having a life expectancy of <12 months. Taken together, the data suggest that antibody microarray analysis of complex proteomes will be a useful tool to define disease associated protein signatures.
