Brief summary

A national, prospective, multi-center, open-label, multi-cohort study comprised of a framework to screen patients for actionable targets and evaluation of molecular profiling guided therapy recommended by MTB based on genomic alterations using targeted and/or immunotherapies outside of the approved indications via local clinical practice (Tier 1 & 2) and clinical trials (Tier 3)

Detailed description

A. The KOSMOS-II study will recruit locally advanced or metastatic solid tumor patients who had disease progression on standard first line anti-cancer treatment and/or has no standard treatment option, in order to prove MTB value to guide treatment within local clinical practice. B. After site physicians confirm that NGS results of patients are available, they preliminarily decide initial treatment before MTB submission and collect informed consent form, and then patients can register to the KOSMOS-II study. Site physicians upload patients' clinical, pathologic, and genomic data for MTB submission. If site physician cannot determine initial treatment before MTB, site physician can record 'initial treatment cannot be determined' and can register the patient for MTB. C. MTB records its treatment recommendations within available drugs list based on uploaded data, then site physicians make a final treatment decision, after informing patient about MTB decision and assessment of patients' final health status and preference. D. Patients who have insufficient genomic information from their NGS results (e.g., lack of variant calling format file or uninterpretable reports) or who are candidates of immunotherapy will submit their tissue and/or blood, for central NGS testing and exploratory biomarker analysis. E. Recommended treatment option There are three different options including (1) Tier 1: Therapeutic use of investigational products (KOSMOS-II drugs), (2) Tier 2: alternative treatment options, and (3) Tier 3: clinical trials

Inclusion criteria

* 19 years of age or older * Histologically proven locally advanced or metastatic solid tumors\*\*\* who showed disease progression on standard first line anti-cancer treatment and/or has no standard treatment option \*\*\* very rare diseases without standard treatment option which form solid mass, such as Erdheim Chester disease can be enrolled after KOSMOS MTB approval * A genomic test results must be available in a MFDS-accredited for laboratories offering service, or in part of clinical trial/study or other commercial labs approved and certified by regulatory bodies compatible with MFDS, such as CLIA. A genomic test can be conducted with tumor tissue as well as plasma circulating tumor DNA. 1.
