Genes contain genetic code which tell the body which proteins to make. Many types of cancer
are caused by changes, or mutations, in a gene called KRAS. Researchers are looking for ways
to stop the actions of abnormal proteins made from the mutated KRAS gene. The so-called G12D
mutation in the KRAS gene is common in people with some solid tumors.

ASP3082 is a potential new treatment for certain solid tumors in people who have the G12D
mutation in their KRAS gene. Before ASP3082 is available as a treatment, the researchers need
to understand how it is processed by and acts upon the body. This information will help find
a suitable dose and to check for potential medical problems from the treatment.

People in this study will be adults with locally advanced, unresectable or metastatic solid
tumors with the G12D mutation in their KRAS gene (G12D mutation). Locally advanced means the
cancer has spread to nearby tissue. Unresectable means the cancer cannot be removed by
surgery. Metastatic means the cancer has spread to other parts of the body. They will have
been previously treated with standard therapies or refused to receive those treatments. In
the European Union (EU) and South Korea, people who have refused to receive treatment with
standard therapies cannot take part.

The main aims of the study are: to check the safety of ASP3082 by itself and together with
cetuximab (a common cancer medicine), how well it is tolerated, and to find a suitable dose
of ASP3082 by itself and together with cetuximab.

This is an open-label study. This means that people in this study and clinic staff will know
that they will receive ASP3082.

This study will be in 2 parts. In Part 1, different small groups of people will receive lower
to higher doses of ASP3082, by itself, or together with cetuximab. Only people with
colorectal cancer will receive ASP3082 together with cetuximab. Any medical problems will be
recorded at each dose. This is done to find suitable doses of ASP3082 by itself or together
with cetuximab to use in Part 2 of the study. The first group will receive the lowest dose of
ASP3082. A medical expert panel will check the results from this group and decide if the next
group can receive a higher dose of ASP3082. The panel will do this for each group until all
groups have received ASP3082 (by itself or together with cetuximab) or until suitable doses
have been selected for Part 2.

In Part 2, other different small groups of people will receive ASP3082 by itself or together
with cetuximab, with the most suitable doses worked out from Part 1. This will help find a
more accurate dose of ASP3082 to use in future studies.

ASP3082, and cetuximab (if used), will be given through a vein. This is called an infusion.
Each treatment cycle is 21 days long. They will continue treatment until: they have medical
problems from the treatment they can't tolerate; their cancer gets worse; they start other
cancer treatment; they ask to stop treatment; they do not come back for treatment.

People will visit the clinic on certain days during their treatment, with extra visits during
the first 2 cycles of treatment. During these visits, the study doctors will check for any
medical problems from ASP3082 by itself or together with cetuximab. At some visits, other
checks will include a medical examination, echocardiogram (ECHO) or multigated acquisition
(MUGA) scan, blood and urine tests and vital signs. Vital signs include temperature, pulse,
breathing rate, and blood pressure. (Blood oxygen levels will also be checked for people
treated with ASP3082 together with cetuximab.) Tumor samples will be taken during certain
visits during treatment and when treatment has finished.

People will visit the clinic within 7 days after stopping treatment. The study doctors will
check for any medical problems from ASP3082 by itself or together with cetuximab. Other
checks will include a medical examination, echocardiogram (ECHO) or multigated acquisition
(MUGA) scan, urine and blood tests and vital signs. After this, people will continue to visit
the clinic every 9 weeks. This is to check the condition of their cancer. They will do this
until 45 weeks after treatment stopped, or if their cancer is worse, they start other cancer
treatment, they ask to stop treatment, or they do not come back for treatment.

Also, people may visit the clinic at 30 days and 90 days after stopping treatment. At the
30-day visit, the study doctors will check for any medical problems from ASP3082 by itself or
together with cetuximab. People will have their vital signs checked and have some bloo

This is a Phase 1/2, open-label, non-randomized, 4-part Phase 1 trial to determine the safety
profile and identify the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D)
of INBRX 106 administered as a single agent or in combination with the anti-PD-1 checkpoint
inhibitor (CPI) pembrolizumab (Keytruda).

This phase I/II trial tests the safety and efficacy of split-course adaptive radiation therapy in combination with immunotherapy with or without chemotherapy for the treatment of patients with stage IV lung cancer or lung cancer that that has spread to nearby tissue or lymph nodes (locally advanced). Radiation therapy is a standard cancer treatment that uses high energy rays to kill cancer cells and shrink tumors. Split-course adaptive radiation therapy uses patient disease response to alter the intensity of the radiation therapy. Immunotherapy with monoclonal antibodies such as pembrolizumab, ipilimumab or nivolumab may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs like carboplatin, pemetrexed, and paclitaxel work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving split-course adaptive radiation therapy with standard treatments like immunotherapy and chemotherapy may be more effective at treating stage IV or locally advanced lung cancer than giving them alone.

This is an umbrella study evaluating the efficacy and safety of multiple treatment
combinations in participants with metastatic or inoperable locally advanced breast cancer.

The study will be performed in two stages. During Stage 1, four cohorts will be enrolled in
parallel in this study:

Cohort 1 will consist of Programmed death-ligand 1 (PD-L1)-positive participants who have
received no prior systemic therapy for metastatic or inoperable locally advanced
triple-negative breast cancer (TNBC) (first-line [1L] PD-L1+ cohort).

Cohort 2 will consist of participants who had disease progression during or following 1L
treatment with chemotherapy for metastatic or inoperable locally-advanced TNBC and have not
received cancer immunotherapy (CIT) (second-line [2L] CIT-naive cohort).

Cohort 3 will consist of participants with locally-advanced or metastatic HR+, HER2-negative
disease with PIK3CA mutation who may or may not have had disease progression during or
following previous lines of treatment for metastatic disease (HR+cohort).

Cohort 4 will consist of participants with locally-advanced or metastatic HER2+ /HER2-low
disease with PIK3CA mutation who had disease progression on standard-of-care therapies (HER2+
/HER2-low cohort).

In each cohort, eligible participants will initially be assigned to one of several treatment
arms (Stage 1). In addition, participants in the 2L CIT-nave cohort who experience disease
progression, loss of clinical benefit, or unacceptable toxicity during Stage 1 may be
eligible to continue treatment with a different treatment combination (Stage 2), provided
Stage 2 is open for enrollment.
