Description of intervention(s) / exposure
Treatment: Drugs - D-1553
Treatment: Drugs - D-1553 in combination with Drug: pembrolizumab, Drug:KEYTRUDA® , Drug: cetuximab, Drug: other

Experimental: Dose escalation of D-1553 monotherapy - Phase 1a will evaluate up to 7 sequential cohorts with different doses of D-1553 to determine safety, tolerability, MTD and RDE in patients with solid tumors with KRasG12C mutation.

Experimental: Dose combination of D-1553 with other therapies - Phase 1b will determine the MTD of D-1553 in combination treatment in subjects with advanced or metastatic NSCLC, CRC and other solid tumors. There are multiple groups in Phase 1b for different tumor types and treatment combinations to evaluate safety, MTD and RP2D.

Experimental: Phase 2 of D-1553 monotherapy and combination therapies - The Phase 2 portion is a multi-arm, parallel, open label study to evaluate the efficacy of D- 1553 single agent and combination treatments in subjects with advanced or metastatic solid tumors with KRas G12C mutation. Enrollment into phase 2 will be opened after confirmation of the recommended phase 2 dose.


Treatment: Drugs: D-1553
D-1553 is a novel, targeted KRasG12C inhibitor that is being developed as a potential oral agent for advanced or metastatic solid tumors with KRasG12C mutation.

Treatment: Drugs: D-1553 in combination with Drug: pembrolizumab, Drug:KEYTRUDA® , Drug: cetuximab, Drug: other

- Subject with histologically proven, locally advanced, unresectable and/or metastatic
solid tumor, for which no standard treatment is available, or the subject is
refractory to or intolerant of existing standard treatment.

cells or DNA. Historical, local laboratory result (up to 5 years prior to this study)
can be used for Phase 1 subjects. Phase 2 subjects must be tested for KRasG12C
mutation by a central laboratory.

including NSCLC and CRC.

- Subject has measurable disease according to RECIST, v1.1.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Subject with unstable or progressive central nervous system (CNS) metastases.

- Subject with acute myocardial infarction, severe/unstable angina; or with cardiac
insufficiency of New York Heart Association Functional Classification Grade 2 or
above.

- Subject has corrected QT interval using Fridericia's formula (QTcF) prolongation at
rest, where the mean QTc interval is > 480 msec based on triplicate measurements of
electrocardiogram (ECG).

- Subject with stroke or other severe cerebrovascular diseases within 12 months before
enrollment;

- Subject with interstitial lung disease or acute lung infection not yet recovered
including but not limited to severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) infection;

- Subject has any history or evidence of substance abuse or medical, psychological or
social conditions that may, in the opinion of the investigator, interfere with
participation in the study or evaluation of the study results.

- Subject has impaired gastrointestinal (GI) function or GI diseases that may
significantly alter the absorption or metabolism of oral medications.

- Subject has unresolved toxicities from prior anticancer therapy, defined as toxicities
(other than alopecia) not yet resolved to NCI CTCAE, v5.0, Grade = 1 (Grade = 2 for
peripheral neuropathy).

- Subject had major surgery within 4 weeks prior to study intervention administration or
last dose of palliative radiation therapy within 2 weeks prior to study intervention
administration.

- Subject is pregnant or lactating.
