Description of intervention(s) / exposure
Treatment: Drugs - ABN401- Escalation Phase
Treatment: Drugs - ABN401- Expansion Phase

Experimental: Escalation phase - Drug: ABN401
Route of Administration: Oral
The study will follow a single patient cohort approach for the first 3 regular dose levels followed by classic 3+3 design. The starting dose is 50mg QD.

Experimental: Expansion phase - Drug: ABN401
Route of Administration: Oral
Once the maximum tolerated dose (MTD) or highest escalation cohort has been reached, or notable efficacy has been observed at a given dose level, a decision as to Recommended Phase 2 dose (RP2D) will be determined. Up to 40 patients with Non-Small Cell Lung Cancer Harboring c-MET Dysregulation will be recruited.


Treatment: Drugs: ABN401- Escalation Phase
Dose administration: Escalation Phase The regular dose levels of ABN401 will range from 50 mg to 1800 mg QD daily for 21 days.

Treatment: Drugs: ABN401- Expansion Phase
Dose administration: Expansion Phase The expansion phase of the study will use the dose and schedule determined to be most appropriate in the dose escalation portion of the study. This may be the MTD and/or the RP2D and will consist of cohorts of NSCLC patients with c-MET dysregulation.
Patients will receive ABN401 800 mg, administered orally once daily for 21 days until disease progression, unacceptable toxicity, or patient withdrawal.

Key inclusion criteria
1. Signed informed consent before any study-specific screening procedures.

2. Male or female = 18 years of age or designated age of majority according to regulatory
authorities, whichever is higher.

3. Body weight = 40 kg and = 110 kg.

4. Eastern Cooperative Oncology Group (ECOG) performance status (PS), 0 or 1.

5. Diagnosis:

1. For the Phase 1 dose escalation, must have:

- Histological or cytological diagnosis of melanoma or any type of carcinoma
or sarcoma,

- Refractory metastatic disease, or refractory locally advanced disease not
amenable to local therapy,

- Metastatic breast or prostate cancer may have bone-only disease.

2. For the Phase 1 extension (pilot expansion), patients must have NSCLC with c-MET
overexpression, MET amplification, or MET exon 14 skipping by local biomarker
assessment as defined in study protocol. The number of patients with only c-MET
overexpression is limited to 50% of enrolled patients in that dosing cohort
including escalation and extension.

6. Progressive disease:

a. Phase 1: Progressive disease on established standard medical anti-cancer therapy
for his/her tumor type or intolerant to such therapy, or in the opinion of the
investigator considered ineligible for a particular form of standard therapy on
medical grounds.

7. At least one measurable lesion per response evaluation criteria in solid tumors
(RECIST) 1.1, with the exception of bone-only disease (i.e., non-measurable disease
per RECIST 1.1) with at least 1 radiological non-target lesion.

8. If not menopausal or surgically sterile, willing to practice at least one of the
following highly effective methods of birth control for at least a (partner's)
menstrual cycle before and for 3 months after study drug administration:

1. True abstinence, when this is in line with the preferred and usual lifestyle of
the patient, from sexual intercourse with a member of the opposite sex,

2. Sexual intercourse with vasectomized male/sterilized female partner,

3. Hormonal female contraceptive (oral, parenteral, intravaginal, implantable or
transdermal) for at least 3 consecutive months prior to investigational product
administration (when not clinically contraindicated as in breast, ovarian and
endometrial cancers),

4. Use of an intrauterine contraceptive device.

9. Resolution of prior-therapy-related AEs (including immune-related AEs but excluding
alopecia) to = Grade 1 per CTCAE, and no treatment for these AEs for at least 2 weeks
prior to the time of enrollment. Alopecia, sensory neuropathy Grade = 2, or other
Grade = 2 AEs not constituting a safety risk based on investigator's judgment are
acceptable.

10. Phase 1 only: minimum of 2 weeks since last dose of hormone therapy.

11. Minimum of > 2 weeks or > 5 half-lives (whichever is longer) between the start of
study treatment since last dose of radiotherapy, chemotherapy, or molecularly targeted
agents or tyrosine kinase inhibitors; minimum of > 3 weeks of the start of study
treatment since last dose of immunotherapy/monoclonal antibodies; > 6 weeks of the
start of study treatment since the last dose of nitrosoureas, antibody-drug conjugates
or radioactive isotopes.

12. Adequate organ function as indicated by the laboratory values.

13. Tissue and/or blood specimens:

a. Phase 1: Available archival formalin-fixed, paraffin-embedded tumor tissue
specimen.

The archival tissue must be:

- collected after progression from most recent prior systemic anti-cancer
treatment, OR

- the samples of previous lines of treatment. If patient wants to participate to
the study but does not want to give the blood and tissue samples for the
exploratory study, patient might be able to participate after discussion and
approval of sponsor and the medical monitor.

14. If the patient agrees to optional pre- and/or study new tumor biopsies (that can be
biopsied based on investigator's assessment) and to provide the tissue for biomarker
analysis, a signed informed consent for the biopsy is required. Tissue obtained for
the biopsy must not be previously irradiated. No systemic antineoplastic therapy may
be received by the patient between the time of the biopsy and the first administration
of ABN401.

For escalation, each dose escalation cohort must try to enroll at least 1 patient who
agrees to biopsies. An exception to the requirement for a new tumor biopsy in at least
one patient per dose level is that if the first patient in a single dose cohort does
not consent to a new tumor biopsy and the cohort is not expanded to 3 or 6 patients, a
biopsy will not be required in that cohort. Note: During pre-treatment FFPE tissue
samples (unstained slides or blocks) or new frozen tissue may be provided for tumor
analyses.

15. Able and willing to comply with the protocol and the restrictions and assessments
therein.

judgement, the patient might be able to be enrolled to the trial under the medical
monitor and the sponsor's approval,

3. Genetic analysis:

a. Phase 1 Extension Cohort, existing data by genetic analysis of the patient's tumor
tissue that may result in an increased probability of being resistant to c-MET

Oddi, biliary cyst or biliary atresia).

5. Prior organ or stem cell transplant.

6. Known active infection with HIV, HTLV-1, hepatitis B virus (HBV), or hepatitis C virus
(HCV):

1. Patients with a history of hepatitis B or C are allowed if HBV DNA or HCV RNA are
undetectable,

apply to patients who underwent successful definitive resection of non-melanoma skin
cancer, superficial bladder cancer, in situ cervical cancer, or other in situ cancers.

10. Active infection requiring therapy. However, subject with minor infections where oral
antibiotic required, (e.g., urinary tract infection, Upper respiratory tract
