4. Subjects with treated brain metastases (surgery, stereotactic
radiation, whole brain radiation or a combination of these modalities)
are eligible if the subject's brain metastases have been documented to
be are stable by head imaging (two scans at least 28 days apart, including the scan obtained during the screening period) and the screening clinical examination is stable and the subject does not require radiation therapy or high-dose steroids (prednisone of 10 mg/day or equivalent). Active screening for brain metastases (e.g., brain computed tomography or magnetic resonance imaging) is not required
5. Subjects with NSCLC (Part A: any histology; Parts B and C: squamous
histology): o Must have received prior treatment with platinum-based therapy
(unless intolerant or not suitable) and a PD-1/PD-L1 inhibitor. A
checkpoint inhibitor should have been administered if approved for the
subject's indication in their locality, alone or in combination with other
therapy
o Subjects with non-squamous cell histology must have undergone
specific genomic testing performed (epidermal growth factor receptor
[EGFR], anaplastic lymphoma kinase [ALK], ROS1, B-RAF)
o Subjects with squamous cell histology are not required to have specific
genomic testing performed (such as EGFR, ALK, ROS1, B-RAF, Kirsten rat
sarcoma [KRAS], MET, RET, and neurotrophic-tropomyosin receptor
kinase [NTRK]); testing may be performed but is not required. If a
subject is known to carry a genetic mutation or translocation, the
subject should have received the appropriate targeted therapy and
progressed or shown intolerance to the therapy prior to enrollment in this protocol
o Subjects with advanced or metastatic stage IV NSCLC with known
EGFR or ALK genomic alterations are eligible if they have progressed on
treatment or did not tolerate appropriate targeted therapy. This would
include osimertinib for T790M mutation-positive NSCLC.
o Subjects with known NSCLC with known ROS1 rearrangement must
have received prior treatment with crizotinib
o Subjects with known B-RAF mutations must have received prior
treatment with a B RAF inhibitor
6. Females of childbearing potential and non-sterile males must agree to
practice highly effective methods of birth control (as described in
Appendix E) for the duration of the study and for 6 months after the last
dose of study drug. In addition, non-sterile males must agree to use a
highly effective method of contraception prior to study entry, while on
study drug, and for a period of 50 days after the last dose of CX-2029
and to avoid sperm donation for the duration of the study and for 6
months after the last dose of study drug.
Inclusion Criteria Specific for Part A, Part B, or Part C
Part A:
1. Histologically or cytologically confirmed metastatic or locally advanced unresectable solid tumor
2. Documented progression or relapse after at least 1 prior systemic therapy, unless systemic therapy is not available or is not suitable. Moreover, subjects must have exhausted available life prolonging therapies

4. Eastern Cooperative Oncology Group (ECOG) 0 to 1
5. Agreement to provide tumour tissue; archival, new, or recent
acquisition confirmed to be available prior to initiation of study drug for
performance of correlative tissue and cellular studies from a tumor site
not previously irradiated; biopsy should not be performed for the
