A Randomized Phase II Trial of Cemiplimab Plus OSE2101 ( TEDOPI®) as Maintenance Therapy in ctDNA Positive NSCL. The Cemited Study.

Обзор

This is a phase II randomized study investigating whether a combination maintenance with Cemiplimab and OSE2101 (TEDOPI®) could increase ctDNA clearance rate versus standard maintenance therapy in HLA-A2 positive NSCLC patients not progressing after 4 cycles of chemo-immunotherapy.

Подробное описание

This is a phase II randomized study investigating whether a combination maintenance with Cemiplimab and OSE2101 (TEDOPI®) could increase ctDNA clearance rate versus standard maintenance therapy in HLA-A2 positive NSCLC patients not progressing after 4 cycles of chemo-immunotherapy.

NSCLC patients with any histology, irrespective of PD-L1 expression levels and candidates for first line metastatic therapy will be screened for HLA-A2 status.

After evaluation of all inclusion and exclusion criteria and after informed consent signature, all eligible patients will receive up to four cycles of chemotherapy and Cemiplimab. The chemotherapy regimen will be selected by the investigator, in accordance with current clinical practice, favoring the use of platinum-based chemotherapy agents.

Patients not progressing after 4 cycles of chemo-immunotherapy will be evaluated for the cTDNA presence (baseline).

If they are positive for ctDNA will be further randomized to standard maintenance therapy or to the combination maintenance of Cemiplimab and OSE2101 (TEDOPI®). In case of ctDNA negative test will be treated with Cemiplimab according to clinical practice.

ctDNA will be further evaluated before cycle 3, and at the time of disease progression or at the end of maintenance therapy.

To summarize ctDNA will be analyzed in patients not progressing after 4 cycles of chemo-immunotherapy (before randomization), during the maintenance therapy and at the time of progression.

An additional blood sample will be collected in all patients at the time of starting first-line chemo-immunotherapy (pre-baseline).
