First-in-human, Phase I/II, Multicenter, Open-Label Study of EMB-01 in Patients with Advanced/Metastatic Solid Tumors

First-in-human, Phase I/II, Multicenter, Open-Label Study of EMB-01 in Patients with
Advanced/Metastatic Solid Tumors

Inclusion Criteria:

Molecular Pre-screening Inclusion criteria (Phase II only)

1. The patient must sign the molecular pre-screening Inform Consent to allow for the
molecular pre-screening process. All patients must have documented evidence of EGFR
and/or cMet aberrations.

Screening Inclusion Criteria

1. Able to understand and willing to sign the Informed Consent Form (ICF).

2. Histologically/cytologically confirmed advanced/metastatic solid tumors with
measurable disease [Response Evaluation Criteria in Solid Tumors (RECIST) v1.1]:

Phase I: advanced/metastatic solid tumors including but not limited to NSCLC,
colorectal cancer, gastric cancer and liver cancer refractory to standard therapy or
for which no standard therapy is available or accessible.

Phase II: Advanced/metastatic NSCLC Patients have confirmed EGFR mutant and/or cMET
aberration, and have progressed after standard treatment (including platinum-based
therapy) or are intolerant to standard treatment. Additionally, patients with T790M
mutation have received FDA/Health Authority approved therapies (if accessible) for
this indication (i.e., osimertinib) and have progressed or became intolerant.

A patient who has refused all currently available therapy is allowed to enroll, but
must be documented in the source record.

3. Must have adequate organ function.

4. Regarding prior anti-tumor therapy:

1. Must have stopped treatment at least 4 weeks or within 5 half-lives.

2. Generalized radiation therapy must have stopped 3 weeks before first dose of EMB
01, or local radiotherapy or radiation therapy for bone metastases must have
stopped 2 weeks before first dose of EMB-01. No therapeutic radiopharmaceuticals
are taken within 8 weeks before first dose of EMB-01.

3. Patients must have recovered to ≤Grade 1 from the adverse effects of such above
treatment before beginning study treatment.

5. Female patient with fertility or male patient whose partner has fertility should use
one or more contraceptive methods for contraception starting from screening period and
continue throughout the study treatment and for 3 months.

6. ECOG score 0 or 1 for phase I, and ≤2 for phase II.

Exclusion Criteria:

Molecular Pre-screening Exclusion Criteria (Phase II only)

Subject who meets any of the follow criteria can't be proceeded to clinical screening:

1. Patients who are unwilling to sign the molecular pre-screening ICF.

2. Patients for whom local EGFR and/or cMET data or the results of central laboratory
testing do not meet the molecular pre-screening inclusion criteria.

Screening Exclusion Criteria

1. Life expectancy < 3 months.

2. Subject with primacy central nervous system (CNS) malignancy or symptomatic CNS
(leptomeningeal or brain) metastases.

3. Pregnant or nursing females.

4. Subjects who have had major surgery within 28 days prior to screening.

5. Serious underlying medical conditions, including but not limited to un-controlled
hypertension, other cardiovascular disease or diabetes, ongoing or active infection,
psychiatric, psychological, familial or geographical condition that, in the judgment
of the investigator, may interfere the compliance with study treatment.
