Dose-limiting toxicities (DLTs) with monotherapy, 400 mg, none reported; 600 mg, n = 3/9 evaluable patients (33%) reported DLTs (grade 3 and 4 alanine aminotransferase and aspartate transaminase increased, and grade 4 drug-induced liver injury). With combination 400 mg, 1/6 (17%) reported DLTs (grade 2 fatigue, nausea, and myalgia); 300 mg, none reported; 600 mg, 3/4 (75%) reported DLTs (grade 2 pyrexia, grade 3 skin reaction, and anaphylactic shock). Grade ≥3 adverse events were reported in 41% of patients receiving monotherapy and 33% receiving combination. TATTON is no longer recruiting patients.

The MTD of savolitinib was 400 mg qd in both cohorts. Data demonstrate an acceptable safety profile for savolitinib alone, or with osimertinib.

Wilms’ tumor 1 (WT1) is overexpressed in various malignancies. DSP-7888 Dosing Emulsion, also known as ombipepimut-S (United States Adopted Name; International Nonproprietary Name adegramotide/nelatimotide), is an investigational therapeutic cancer vaccine comprising two synthetic peptides derived from WT1 to promote both cytotoxic T-lymphocyte (CTL) and helper T-lymphocyte-mediated immune responses against WT1-expressing tumors.

The aim of this study was to report the results from a phase I dose-escalation study (NCT02498665) that evaluated DSP-7888, administered either intradermally (ID) or subcutaneously (SC), in patients with recurrent or advanced malignancies associated with overexpression of WT1.

In this phase I dose-escalation study, patients with recurrent or advanced malignancies associated with overexpression of WT1 who progressed on, were intolerant to, or not a candidate for standard therapy or who presented with a malignancy that had no definite standard therapy received escalating doses of) of those administered ID and SC DSP-7888, respectively.

DSP-7888 Dosing Emulsion was well tolerated, with no dose-limiting toxicities, in patients with recurrent or advanced malignancies. Higher WT1-specific CTL induction activity was noted with ID compared with SC administration; because of this, the ID route was selected for further evaluation in the clinical program.

Multiple myeloma (MM) is an incurable disease of malignant plasma cells in the bone marrow (BM). Adaptive responses to hypoxia may be an essential element in MM progression and drug resistance. This metabolic adaptation involves a decrease in extracellular pH (pHe), and it depends on the upregulation of glucose transporters (GLUTs) that is common in hypoxia and in cancer cells. CEST MRI is an imaging technique that assesses pHe indirectly by the exchange rate of magnetic saturation transfer between labile protons on a solute and water. Thus, this study aimed to determine the feasibility of acidoCEST MRI for pHe measurement using an orthotopic mouse model of MM compared with GLUT1 immunofluorescence staining as a reference.

Orthotopic BM engrafted MM xenografts were established in NSG/NOD mice using the human RPMI8226 myeloma cell line. AcidoCEST MRI was performed approximately 6 weeks after intravenous challenge, before and after intravenous administration of iopamidol. BM pHe values were generated via fid by acidoCEST MRI showed strong correlations with the metabolic phenotype of BM tumor assessed by immunofluorescent histological assessment of GLUT1 overexpression.Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease characterized by the development of renal cysts and progression to renal failure. Preimplantation genetic testing-monogenic disease (PGT-M) is an alternative option to obtain healthy babies. However, de novo PKD1 mutation of one of the spouses or the absence of a positive family history poses a serious challenge to PGT-M. Here, we described a comprehensive strategy which includes preimplantation genetic testing for aneuploidies (PGT-A) study and monogenic diagnosis study for ADPKD patients bearing de novo mutations. The innovation of our strategy is to use the gamete (polar body or single sperm) as proband for single-nucleotide polymorphism (SNP) linkage analysis to detect an embryo’s carrier status. Nine ADPKD couples with either de novo mutation or without a positive family history were recruited and a total of 34 embryos from 13 PGT-M cycles were examined. Within these nine couples, two successfully delivered healthy babies had their genetic status confirmed by amniocentesis. This study provides a creative approach for embryo diagnosis of patients with de novo mutations or patients who lack essential family members for linkage analysis.

Operative complications affect recurrence in non-breast malignancies. Rising rates of mastectomy with immediate reconstruction and their increased post-operative complications fuel concerns for poorer outcome in breast cancer (BC). We sought to determine the effect of complications on recurrence in BC patients.

A single-institution retrospective review was conducted of incident BC treated with mastectomy and immediate reconstruction. Overall survival and recurrence were compared between patients with complications to those without.

Of 201 patients (350 mastectomies, 86 nipple-sparing), 62 (30.8%) had a surgical complication. Patients with complications were older, but groups were similar for type of reconstruction, tobacco use, hormone receptor status, HER2, lymphovascular invasion, and pathologic stage (all p > 0.05). Twenty-two complications (10.9%) were infection, 5 (2.5%) dehiscence, 14 flap necrosis (7%), 21 hematomas (10.4%), and 8 nipple necroses (9%). Recurrence occurred in 18 (8.9%) patients 4 local, 2 regional, and 12 distant. After 8.9years of median follow-up, patients with complications trended towards higher recurrence (hazard ratio (HR) 2.23, log-rank p = 0.08, Cox regression p = 0.05), particularly with nipple necrosis (HR 3.28, log-rank p = 0.09, regression p = 0.06). Patients with other complications had similar recurrence-free survival to those without (all p > 0.05). Higher stage (HR 13.66, log-rank p = 0.03) and adjuvant radiation (HR 2.78, log-rank p = 0.04) cases were more likely to recur. Patients with complications had similar overall survival to those without (log-rank p > 0.05).

BC patients with surgical complications do not have lower overall survival. BLU-554 ic50 This finding may be due to the improved prognosis compared to non-breast malignancies.
