Sitravatinib is a potential EGFR inhibitor and induce a new death phenotype in Glioblastoma
SummaryGlioblastoma (GBM) is a highly lethal neurological tumor that presents significant challenge for clinicians due to its heterogeneity and high mortality rate. Despite extensive research, there is currently no effective drug treatment available for GBM. Research evidence has consistently demonstrated that the epidermal growth factor receptor (EGFR) promotes tumor progression and is associated with poor prognosis in several types of cancer. In glioma, EGFR abnormal amplification is reported in approximately 40% of GBM patients, with overexpression observed in 60% of cases, and deletion or mutation in 24% to 67% of pati...

POTEE mutation as a potential predictive biomarker for immune checkpoint inhibitors in lung adenocarcinoma
SummaryPrecise selection of patients who could benefit from immune checkpoint inhibitors (ICIs) is an important challenge for immunotherapy in lung cancer.POTEE (POTE Ankyrin Domain Family Member E) is a member of one primate-specific gene family which have been identified as cancer-related antigens and potential target for immunotherapy of cancer. Here, we investigated the correlation betweenPOTEE mutation and the clinical outcome of ICIs treatment in non-small cell lung cancer (NSCLC). We merged three NSCLC cohorts (n = 165) to assess predictive value ofPOTEE mutation of immunotherapy efficacy in NSCLC. The prognostic an...

Metabolism Pathways of Major Therapeutics for Treating Monkeypox Mono- and Co-infection with Human Immunodeficient Virus or SARS-CoV-2
Curr Drug Metab. 2023 Jun 7. doi: 10.2174/1389200224666230607124102. Online ahead of print.ABSTRACTMonkeypox is a zoonotic viral disease and remains endemic in tropical regions of Central and West Africa. Since May of 2022, cases of monkeypox have soared and spread worldwide. Confirmed cases have shown no travel history to the endemic regions as seen in the past. The World Health Organization declared monkeypox a global public health emergency in July 2022, and the United States government followed suit one month later. The current outbreak, in contrast to traditional epidemics, has high coinfection rates, particularly wit...

A phase I/II study of LY3022855 with BRAF/MEK inhibition in patients with Melanoma
AbstractBRAF/MEK targeted therapies and immune checkpoint inhibition have dramatically improved disease control and survival of patients with advanced melanoma. However, most patients do not have durable benefit from either of these therapies. BRAF targeted therapy often has a limited duration of efficacy due to the development of resistance. Pre-clinical data suggest that one possible way to overcome resistance to BRAF/MEK targeted therapy may be the addition of CSF1R inhibition. In this phase I/II study we evaluated the safety and efficacy of LY3022855, an anti-colony stimulating factor-1 receptor (CSF-1R) monoclonal ant...

Degradation of MYC by the mutant p53 reactivator drug, COTI-2 in breast cancer cells
AbstractTP53 (p53) and MYC are amongst the most frequently altered genes in cancer. Both are thus attractive targets for new anticancer therapies. Historically, however, both genes have proved challenging to target and currently there is no approved therapy against either. The aim of this study was to investigate the effect of the mutant p53 reactivating drug, COTI-2 on MYC. Total MYC, pSer62 MYC and pThr58 MYC were detected using Western blotting. Proteasome-mediated degradation was determined using the proteasome, inhibitor MG-132, while MYC half-life was measured using pulse chase experiments in the presence of cyclohex...

Bispecific anti-CD3 ×anti-CD155 antibody mediates T-cell immunotherapy in human haematologic malignancies
In conclusion, CD155Bi-Ab enhances the ability of T cells to kill haematologic tumour cells, and therefore, CD155 may serve as a novel target for immunotherapy against haematologic malignancies. (Source: Investigational New Drugs)

Automated radiosynthesis of 1 ‐(2‐[18F]fluoroethyl)‐L‐tryptophan ([18F]FETrp) for positron emission tomography (PET) imaging of cancer in humans
In this work, we report a fully automated radiosynthesis of [18F]FETrp on a Synthra RNPlus research module, including a one-pot two steps radiosynthesis, dual independent chiral and reverse-phase semipreparative HPLC purifications, and solid-phase extraction-assisted formulation. The presented approach has led to its Investigational New Drug application and approval that allows the testing of this tracer in humans. The radiotracer 1-(2-[18F]fluoroethyl)-L-tryptophan (L-[18F]FETrp or [18F]FETrp) is a substrate of indoleamine 2,3-dioxygenase, the initial and key enzyme of the kynurenine pathway associated with tumoral immune...

Pharmacokinetics, safety, and antitumor activity of talazoparib monotherapy in Chinese patients with advanced solid tumors
AbstractTalazoparib, a poly(ADP-ribose) polymerase inhibitor, has demonstrated efficacy in the treatment of advanced breast and prostate cancers in Western populations. This open-label, phase 1 study investigated the pharmacokinetics, safety, and antitumor activity of talazoparib monotherapy in Chinese patients with advanced solid tumors. Molecularly unselected patients ( ≥18 years) with advanced solid tumors resistant to standard therapy received talazoparib (oral, 1 mg once daily). Primary endpoint was characterization of single-dose and steady-state pharmacokinetics. Secondary endpoints evaluated safety, unconfirmed o...

Abdominal pain accompanied by elevated serum inflammatory markers and biliary enzymes for diagnosing immune checkpoint inhibitor-induced sclerosing cholangitis
In this study, we aimed to summarize the clinical features of irSC. Clinical data were collected retrospectively from 1,393 patients with advanced malignancy treated with immune-checkpoint inhibitors (ICIs) between August 2014 and October 2021. We analyzed patients with immune-related adverse events of liver injury (liver-irAEs) and compared irSC and non-irSC groups. Sixty-seven patients (4.8%) had a liver-irAE ( ≥ grade 3) during the follow-up period (median, 262 days). Among these, irSC was observed in eight patients (11.9%). All patients in the irSC group were treated with anti-PD-1/PD-L1 antibodies. Compared with the...

A phase Ib study of adavosertib, a selective Wee1 inhibitor, in patients with locally advanced or metastatic solid tumors
This study investigated dosing schedules for adavosertib monotherapy, determining the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D) in patients with advanced solid tumors.Patients received oral adavosertib qd or bid on a 5/9 schedule (5 days on treatment, 9 days off) in 14-day cycles, or qd on one of two 5/2 schedules (weekly, or for 2 of 3 weeks) in 21-day cycles. Safety, efficacy, and pharmacokinetic analyses were performed.Sixty-two patients (female, 64.5%; median age, 61.5 years; most common primary tumors: lung [24.2%], ovary [21.0%]) received treatment (qd schedules, n = 50; bid schedules, n...

Epigenetic modifiers either individually or in specific combinations impair viability of patient-derived glioblastoma cell line while exhibit moderate effect on normal stem cells growth
In this study, we extended our investigation to include a patient-derived GBM stem cell line. Our results showed that the combinations of modulators of histone and DNA covalent modifying enzymes that synergistically suppress D54 and U87 cell line growth also impair the viability of the patient-derived GBM stem cell line. These findings suggest that epigenetic modifiers alone or in specific combinations exhibit a cytotoxic effect on established and low-passage patient-derived GBM cell lines, and thus could be a promising therapeutic approach for this type of brain cancer.

Comparison of safety outcomes of anticancer drugs in Japanese and non-Japanese patients in multi-regional clinical trials: meta-analysis of safety profiles
This study aimed to compare the safety outcomes of anticancer drugs in Japanese and non-Japanese patients in multi-regional clinical trials (MRCTs), regardless of the type of cancer or drug. All new approvals of oncology drugs in Japan from January 2009 to December 2018 were searched through the Pharmaceuticals and Medical Devices Agency website. The odds ratio (OR) for comparing the incidence of AEs between Japanese and non-Japanese patients was estimated using the Mantel –Haenszel method with a random effect model. Sixty-six multi-regional phase 3 trials were identified involving 43,712 patients. Severe AE, AE leading ...
