Pancreatic cancer is the fourth leading cause of cancer-related death among men and women in United States. A major challenge treatment remains patients’ advanced disease at diagnosis. The NCCN Guidelines for Adenocarcinoma provides recommendations diagnosis, evaluation, treatment, follow-up patients with pancreatic cancer. Although survival rates remain relatively unchanged, newer modalities including targeted therapies, provide hope improving patient outcomes. Sections manuscript have been...

Abstract HER2 mutations are infrequent genomic events in biliary tract cancers (BTCs). Neratinib, an irreversible, pan-HER, oral tyrosine kinase inhibitor, interferes with constitutive receptor activation and has activity -mutant tumours. SUMMIT is open-label, single-arm, multi-cohort, phase 2, ‘basket’ trial of neratinib patients solid tumours harbouring oncogenic somatic (ClinicalTrials.gov: NCT01953926). The primary objective the BTC cohort, which now complete, first response rate (ORR)...

Pelareorep is an intravenously delivered oncolytic reovirus that can induce a T-cell-inflamed phenotype in pancreatic ductal adenocarcinoma (PDAC). Tumor tissues from patients treated with pelareorep have shown replication, T-cell infiltration, and upregulation of PD-L1. We hypothesized combination pembrolizumab chemotherapy PDAC would be safe effective.A phase Ib single-arm study enrolled who progressed after first-line treatment. Patients received pelareorep, pembrolizumab, either...

Ampullary cancers refer to tumors originating from the ampulla of Vater (the ampulla, intraduodenal portion bile duct, and pancreatic duct), while periampullary may arise locations encompassing head pancreas, distal duodenum, or Vater. are rare gastrointestinal malignancies, prognosis varies greatly based on factors such as patient age, TNM classification, differentiation grade, treatment modality received. Systemic therapy is used in all stages ampullary cancer, including neoadjuvant...

PURPOSE Metastatic pancreatic adenocarcinoma (mPC) remains a difficult-to-treat disease. Fluorouarcil, oxaliplatin, irinotecan, and leucovorin (FFX) is standard first-line therapy for mPC patients with favorable performance status good organ function. In phase I study, devimistat (CPI-613) in combination modified FFX (mFFX) was deemed safe exhibited promising efficacy mPC. METHODS The AVENGER 500 trial (ClinicalTrials.gov identifier: NCT03504423 ) global, randomized III conducted at 74 sites...

539 Background: Tinengotinib is a spectrum-selective multi-kinase inhibitor with unique FGFR-binding mechanism. It potently inhibits FGFR2 fusion/rearrangement and acquired resistant mutations in pre-clinical models early clinical studies cholangiocarcinoma (CCA). Here we present the preliminary efficacy safety of tinengotinib (TT-00420) phase II trial TT420C1206 (NCT04919642). Methods: Eligible patients (pts) advanced/metastatic CCA exhausting standard treatment options received 10 mg QD....

Oral squamous cell carcinoma (OSCC) is a deadly disease that comprises 60% of all head and neck cancers. The leaves the Neem tree (Azadirachta indica) have been used in traditional Ayurvedic medicine for centuries to treat numerous oral maladies are known significant anti-inflammatory properties. We hypothesize highly pure super critical CO2 leaf extract (SCNE) prevents initiation progression OSCC via downregulation intra-tumor pro-inflammatory pathways, which promote tumorigenesis. Hence,...

TPS153 Background: The clinical benefit of approved therapies in patients (pts) with metastatic colorectal cancer (mCRC) who progress on first- and second-line chemotherapy (FOLFOX FOLFIRI) is limited. In pts chemotherapy-refractory RAS wild type mCRC, antibodies targeting EGFR offer a monotherapy response rate approximately 20% progression-free survival (PFS) 4 months (Price 2014). HER2 validated target gastric breast cancers, amplification occurring ~3–5% mCRC. Tucatinib (TUC), recently...

Abstract Background Nintedanib is a tyrosine kinase inhibitor with efficacy in bevacizumab-resistant colorectal cancer models. This phase I/II study evaluated the recommended II dose and of nintedanib capecitabine refractory metastatic cancer. Methods Key eligibility criteria included ECOG performance status 1 or lower. The primary endpoint was 18-week progression-free survival (PFS). A 1-sided binomial test (at α = .1) compared observed PFS historic control .25. Results Forty-two patients...

Despite the occurrence of HER2 amplification/overexpression (HER2+) in ~3% to 5% all patients with metastatic colorectal cancer (mCRC) and up ~10% RAS/BRAF wild-type mCRC, there are currently no FDA- or EMA-approved HER2-directed therapies for HER2+ mCRC. Patients mCRC who progress on early lines chemotherapy regimens receive limited clinical benefit from current standard-of-care treatments. Tucatinib is a highly selective, HER2-directed, tyrosine kinase inhibitor. The MOUNTAINEER trial...
