Brief summary: To evaluate the safety, tolerability, pharmacokinetics and antitumor activity of YYB101 with Irinotecan, patients who are metastatic or recurrent Colorectal Cancer Patients.

Detailed description: Metastatic or recurrent colorectal cancer patients will be enrolled to evaluate the safety, tolerability, pharmacokinetics, and efficacy of YYB101 in combination with irinotecan. In Phase 1b, YYB101 20 mg/kg in combination with irinotecan 150 mg/m2 will be administered as a dose level 0, and the safety and pharmacokinetic assessments will be performed based on the DLT after a 4-week treatment period. If no DLT occurs during the 4-week observation period, dosing will be continued every 2 weeks until progressive disease (PD) or unacceptable toxicity occurs. After completion of Phase 1b, the SRC will determine the RP2D of YYB101 and irinotecan, and Phase 2a will be initiated. Stage 2 will proceed when unconfirmed response is observed in one or more subjects out of 10 subjects evaluable for tumor in Phase 2a Stage 1 which includes the RP2D dose cohort in Phase 1b.

Eligibility criteria: Inclusion Criteria:

1. Male and female patients aged ≥ 19 years
2. Patients with histologically confirmed metastatic or recurrent colorectal cancer

   * Patients who progressed after standard anticancer treatment including existing fluoropyrimidine, oxaliplatin, and irinotecan
   * Patients who received anticancer treatment including irinotecan for at least 6 weeks, with progression confirmed radiologically while on anticancer treatment or within 6 months (24 weeks) after completion of anticancer treatment
   * Adjuvant therapy is acknowledged as an anticancer therapy, if PD is confirmed within 6 months (24 weeks) after the last dose
   * Patients who are unable to undergo radical resection 3) Patients with Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 1 4) Patients with life expectancy of at least 12 weeks 5) Patients with confirmed adequate hematologic, renal and hepatic function based on the following criteria:
   * ANC ≥ 1,500/μL (without granulocyte colony-stimulating factor (G-CSF) administration within 2 weeks prior to baseline)
   * Platelet ≥ 100,000/μL (without transfusion within 2 weeks prior to baseline)
   * Hemoglobin ≥ 9 g/dL (without transfusion within 4 weeks prior to baseline)
   * Serum creatinine ≤ 1.5 mg/dL or estimated glomerular filtration rate (eGFR) (or GFR) ≥ 60 mL/min/1.73 m2
   * Aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 2.5 X upper limit of normal (ULN) (AST and ALT ≤ 5 X ULN for subjects with confirmed hepatic metastases)
   * Total bilirubin ≤ 1.5 X ULN
   * Prothrombin time (PT) and activated partial thromboplastin time (aPTT) ≤ 1.5 X ULN
   * Urine protein to creatinine ratio (UPC) \< 1.0 0 (g/g)a a UPC will be conducted only when urine dipstick protein level is ≥ 1 positive (+).

6. Patients with a measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST), Version 1.1 7. Patients who voluntarily agree to participate in the study and sign the informed consent form

Exclusion Criteria:

1. Patients with hematologic malignancy including lymphoma
2. Patients who received chemotherapy, biological therapy, immunotherapy (including immune checkpoint inhibitors), or radiotherapy within 4 weeks prior to baseline for the treatment of metastatic or recurrent colorectal cancer (Participation is not allowed if nitrosoureas or mitomycin is administered within 6 weeks prior to baseline or if biological target antibody is administered within 8 weeks prior to baseline)
3. Patients with a history of primary malignancy other than colorectal cancer. However, the patients are permitted to participate if:

   * They have not received any treatment for the tumor or are disease-free for at least 5 years (For papillary carcinoma of thyroid, participation in the study is allowed even if it has not been more than 5 years after radical resection.)
   * At least 1 year has passed since complete resection of basal/squamous cell carcinoma of the skin or successful treatment of cervical carcinoma in situ
