K-Basket, Avelumab, Biomarker-driven, Advanced Solid Tumor

• Status: Unknown status
• Trial end date: 2020-07-01
• Target enrollment: 0
• Participant gender: All

Summary

Investigators have conducted K-BASKET trial (Korea-Biomarker-driven multi-arm drug-screening, knowledge and evidence-generating targeted trial), which was based on the specific genetic aberration, not the cancer type, which could accelerate matching the right drug to the right target so that every cancer patient could get the right specific drug based on the specific genetic biomarker, like NCI-MATCH trial. Next generation sequencing (NGS) focusing panel has the mutation and copy number variation of MET, PIK3CA and AKT. Investigators will open new treatment arms during the progress of K-BASKET trial. Patient with PD-L1 positive or EBV positive or MSI-H or POLE/POLD1 mutation tumor will be assigned to Avelumab monotherapy.

• Phase: Phase 2

Exclusion Criteria:

• Previous treatment with immune checkpoint inhibitor (Anti-PD1, Anti-PDL1, Anti-CTLA4 etc.)

• Known severe hypersensitivity reactions to monoclonal antibodies (Grade ≥ 3 NCI CTCAE v 4.03), any history of anaphylaxis, or uncontrolled asthma (that is, 3 or more features of partially controlled asthma)

• Prior organ transplantation, including allogeneic stem cell transplantation

• Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent:

• All subjects with brain metastases, except those meeting the following criteria:

• Subjects with clinically significant (i.e., active) cardiovascular medical history:

cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure (≥ New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication

• Unresolved toxicity of Grade >1 attributed to any prior therapies (excluding alopecia, skin pigmentation and anemia).

• Pregnancy or lactation

• Interstitial lung disease

• Known alcohol or drug abuse

• All other significant diseases (for example, inflammatory bowel disease, uncontrolled asthma), which, in the opinion of the Investigator, might impair the subject's tolerance of trial treatment

• Any psychiatric condition that would prohibit the understanding or rendering of informed consent

• Vaccination within 4 weeks of the first dose of avelumab and while on trial is prohibited except for administration of inactivated vaccines
