Background: Advanced small cell lung cancer (SCLC), extra-pulmonary neuroendocrine carcinoma (EP-NEC) and pancreatic adenocarcinoma (PDA) are rapidly progressive cancers characterized by unbridled replication stress. Patients with these malignancies possess dismal prognoses with limited options after initial first-line chemotherapy. These tumors rely on the integrity of DNA damage repair pathways to ensure genomic stability. The ataxia telangiectasia and Rad3-related (ATR) pro...

Background: Radiation is a potent inducer of DNA double-strand breaks, and ribonucleotide reductase (RNR) is the rate-limiting enzyme in the synthesis and repair of DNA, making RNR-targeted therapy a rationale therapeutic strategy for radiosensitization. ETCTN 10388 (NCT04234568) evaluated safety and efficacy of the combination of lutetium 177 DOTATATE, a beta-emitting radionuclide in combination with triapine, a ribonucleotide reductase (RNR) inhibitor. <p class="abstext"...

ETCTN 10450: A phase I trial of peposertib and lutetium 177 DOTATATE in well-differentiated somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

Background: Radiolabeled somatostatin analogs provide a means of delivering targeted radiation with a high therapeutic index to NETs that express somatostatin receptors (SSTRs). We hypothesize that the addition of an effective radiation sensitizer could help improve the antitumor activity of Lutathera. Radiation is a potent inducer of DNA damage. The primary repair mechanism of radiation-induced double-stranded breaks (DSBs) is the nonhomologous end-joining (NHEJ) pathway, in ...
