Clinical Trial Summary

This study is a Phase I/II, open-label, dose escalation, and cohort expansion study designed to characterize the safety, tolerability, pharmacokinetic (PK), pharmacodynamics (PD), immunogenicity, and preliminary antitumor activity of ZL-1211 administered by IV infusion on a every 2 weeks (Q2W) schedule.

Description:

The study consists of two stages, Phase I -Dose Escalation Phase to determine the maximum tolerated dose (MTD) or maximum administered dose (MAD) (if no MTD is defined) of ZL-1211, and Phase II -Cohort Expansion Phase to further define the safety and initial antitumor activity of ZL-1211 with the dose established in the Dose Escalation Phase.

3. Hemoglobin = 9 g/dL without transfusion in the 2 weeks prior to screening.

10. Prothrombin time, international normalized ratio or/and activated partial thromboplastin time < 1.5 × ULN.

11. Recovery, to Grade 0-1, from AEs related to prior anticancer therapy except alopecia, < Grade 2 sensory neuropathy, lymphopenia.

Exclusion Criteria:

1. Patient with known human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome related illness or known active or chronic hepatitis B virus infection or hepatitis C virus.

2. Any uncontrolled active infection.

3. Previous exposure to any CLDN18.2 antibody or CLDN18.2 chimeric antigen receptor T cell therapy.

4. Newly diagnosed or symptomatic brain metastases anticonvulsants are allowed.

5. Severe cardiovascular disease; New York Heart Association Class II-IV heart failure within 6 months of screening; uncontrolled arrhythmia within 6 months of screening.

6. Anticancer therapy or radiation therapy within 5 half-lives or 4 weeks (whichever is shorter) prior to screening; palliative radiotherapy within 2 weeks prior to screening.

7. Major surgery within 4 weeks prior to first dose; minor surgery within 2 weeks prior to first dose.

8. Symptomatic intrinsic lung disease (chronic obstructive pulmonary disease, pulmonary fibrosis).

9. Gastrointestinal abnormalities including:

1. Documented unresolved gastric outlet obstruction or persistent vomiting defined as = 3 episodes within 24 hours.

2. Active peptic ulcer disease required treatment in the past 3 months.

3. Gastrointestinal bleeding as evidenced by hematemesis, hematochezia, or melena in the past 3 months without evidence of resolution documented by endoscopy or colonoscopy.

4. Documented active colitis within 4 weeks prior to study entry, including infectious colitis, radiation colitis and ischemic colitis.

5. History of ulcerative colitis or Crohn's disease.
