PALACE: Cemiplimab Trial According to ctDNA Levels

"Patients will receive Cemiplimab administered by IV infusion over 30 minutes every 28 days (Q3W) until disease progression, unacceptable toxicity, loss of clinical benefit as judged by the investigator or up to a maximum of 2 years of treatment.~Structure: is a high affinity hinge-stabilized IgG4P human antibody to the PD-1receptor (PDCD1, CD279) that blocks PD 1/PD L1 mediated T cell inhibition. Binding of the PD-1 ligands PD-L1 and PD-L2, to the PD-1 receptor found on T cells, inhibits T-cell proliferation and cytokine production. Upregulation of PD-1 ligands occurs in some tumors and signaling through this pathway can contribute to inhibition of active T-cell immune surveillance of tumors.~Route of administration: Intravenous infusion."

"Patients will receive Carboplatin administered by IV infusion for 2 cycles.~Structure: The cis-diamino (cyclobutane-1, 1 dicarboxylate) platin.~Stability: 24 hours at ambient temperature in 5% glucose, glucosaline or physiologic saline. It is recommended not to dilute with chlorinated solutions since this could affect the carboplatin.~Route of administration: Intravenous infusion."

"Patients will receive Paclitaxel administered by IV infusion for 2 cycles.~Structure: A diterpene whose composition is: 5b, 20- epoxy-1, 2a, 4,7b, 10b, 13a-hexahidroxytax-11-en 9 one 4,10-diacetate 2-benzoate 13-ester with (2R,3S)- N-benzoyl-3-phenylisoserine.~Stability: Concentrations of 0.3-1.2 mg/ml in 5% dextrose or normal saline have demonstrated chemical and physical stability for more than 27 hours at ambient temperature (25ºC approximately).~The intact vial must be stored between 15º and 25ºC.~Guidelines of Paclitaxel administration: Paclitaxel must be administered by infusion over 3 hours in dextrose (D5W) or normal saline (NS). The concentration must not exceed 1.2 mg/ml."
