Inclusion Criteria:
General Inclusion Criteria
- Male/female participants who are at least 18 years of age on the day of signing
informed consent with advanced/metastatic cutaneous melanoma, NSCLC or MSS mCRC who
meet the following criteria will be enrolled in this study.
- Male participants:
o A male participant must agree to use a contraception during the treatment period and
for at least 120 days after the last dose of study treatment and refrain from donating
sperm during this period.
- Female participants:
- A female participant is eligible to participate if she is not pregnant, not
breastfeeding, and at least one of the following conditions applies:
- Not a woman of childbearing potential (WOCBP);OR
- A WOCBP who agrees to follow the contraceptive guidance during the treatment
period and for at least 120 days after the last dose of study treatment.
Cohort 1 (MSS mCRC)
- MSS is defined as 0-1 allelic shifts among 3-5 tumor microsatellite loci using a
PCR-based assay or immunohistochemistry.
- Must have received prior therapy with a fluoropyrimidine, oxaliplatin, and irinotecan.
- Prior treatment with an anti-PD-1/anti-PD-L1 or anti-CTLA-4 antibody is not allowed.
- Prior treatment with BRAF/MEK inhibitor therapy (if BRAF mutated) and/or EGFR targeted
antibody (if KRAS WT) are allowed.
- No more than 2 prior lines of therapy for metastatic disease.
- Adjuvant therapy will count as 1 prior line of therapy if received within the prior 6
months; but if not does not count towards prior line of therapy.
- PIV (pan-immune-inflammation) cutoff of 1200 obtained on labs obtained during
Screening.
Cohort 2 (PD-1 R/R melanoma)
- PD-1 refractory disease as defined as progression on treatment with anti-PD-(L)1
inhibitor administered either as monotherapy or in combination with other checkpoint
inhibitors or other therapies. PD-1 treatment progression is defined by meeting all of
the following criteria:
- Receipt of at least 2 doses of an approved or investigational anti-PD-(L)1
inhibitor.
- Demonstrated PD after anti-PD-(L)1 inhibitor as defined by RECIST v1.1. The
initial evidence of PD is to be confirmed by a second assessment no less than 4
weeks from the date of the first documented PD, in the absence of rapid clinical
progression (as defined by the criteria in the sub-point below).
- Progressive disease that has been documented within 12 weeks from the last dose
of anti-PD-(L)1 inhibitor.
- Progressive disease is determined according to iRECIST.
- This determination is made by the investigator. Once PD is confirmed, the initial date
of PD documentation will be considered the date of disease progression.
- Subjects who progressed on/within 3 months of adjuvant therapy with anti-PD-(L)1
inhibitor will be allowed; an adjuvant therapy will count as 1 prior line of therapy
if received within the prior 6 months.
- Prior treatment with an anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA-4)
antibody is allowed but not required.
- Prior treatment with BRAF/MEK inhibitor therapy (if BRAF mutated) is allowed but not
required.
- No more than 5 prior lines of therapy.
Cohort 3 (PD-1 R/R NSCLC)
- PD-1 refractory disease as defined as progression on treatment with anti-PD-(L)1
inhibitor administered either as monotherapy or in combination with other checkpoint
inhibitors or other therapies. PD-1 treatment progression is defined by meeting all of
the following criteria:
- Has received at least 2 doses of an approved or investigational anti-PD-(L)1
inhibitor.
- Has demonstrated PD after anti-PD-(L)1 inhibitor as defined by RECIST v1.1. The
initial evidence of PD is to be confirmed by a second assessment no less than 4
weeks from the date of the first documented PD, in the absence of rapid clinical
progression (as defined by the criteria in the sub-point below).
- Progressive disease has been documented within 12 weeks from the last dose of
anti-PD-(L)1 inhibitor.
- Progressive disease is determined according to iRECIST.
- This determination is made by the investigator. Once PD is confirmed, the initial date
of PD documentation will be considered the date of disease progression.
- Subjects who progressed on/within 3 months of adjuvant therapy with anti-PD-(L)1
inhibitor will be allowed; an adjuvant therapy will count as 1 prior line of therapy
if received within the prior 6 months.

antibody is allowed but not required.

and progressed or have demonstrable intolerance to approved targeted therapy.
- Patients with NSCLC with known oncogenic driver (including but not limited to EGFR,
ALK, ROS, MET alterations) must have received and progressed past driver-specific
therapy.
- No more than 5 prior lines of therapy.
Other Criteria

previously irradiated to undergo tumor biopsy (core, punch, incisional or excisional).

- A pan-immune-inflammation (PIV) cutoff of 1200 (obtained on labs during Screening)
- Female subject of childbearing potential should have a negative urine or serum
pregnancy within 72 hours prior to receiving the first dose of study medication. If
the urine test is positive or cannot be confirmed as negative, a serum pregnancy test
will be required.
- Female subjects of childbearing potential should be willing to use 2 methods of birth
control or be surgically sterile or abstain from heterosexual activity for the course
of the study through 120 days after the last dose of study medication. Subjects of
childbearing potential are those who have not been surgically sterilized or have not
been free from menses for > 1 year.
- Male subjects should agree to use an adequate method of contraception starting with
the first dose of study therapy through 120 days after the last dose of study therapy.

- Has an active infection requiring systemic therapy.
- Has a history or current evidence of any condition, therapy, or laboratory abnormality

the subject to participate, in the opinion of the treating investigator.
- Has known psychiatric or substance abuse disorders that would interfere with
cooperation with the requirements of the trial.
