A Phase I/II, Open-Label Study to Investigate the Safety, Clinical Activity, Pharmacokinetics, and Pharmacodynamics of GSK3145095 Administered Alone and in Combination With Anticancer Agents Including Pembrolizumab in Adult Participants With Selected Advanced Solid Tumors

In an unbiased CRISPR screen, RIPK1 was identified as a top gene contributing to
immunotherapy resistance. In addition, RIPK1 has been reported to drive pancreatic
oncogenesis. In murine models, inhibition of RIPK1 kinase activity in the pancreatic tumor
microenvironment leads to the replacement of tumor-permissive myeloid infiltrates with innate
cells that promote an effective antitumor response by adaptive cells. The investigators
hypothesize that inhibition of RIPK1 in human pancreatic cancer subjects will modulate the
immune infiltrate to sensitize tumors to checkpoint blockade.

Study 205013 is a Phase 1 FTIH study of GSK3145095 alone and in combination with other
anticancer agents including pembrolizumab in subjects with pancreatic ductal adenocarcinoma
(PDAC) and other selected tumors. The study includes up to 4 parts: Part 1 dose escalation
will be conducted in approximately 30 adult subjects with advanced or metastatic PDAC using
escalating doses of GSK3145095 as monotherapy only. Part 2 will combine escalating doses of
GSK3145095 with 200 milligram (mg) pembrolizumab. Dose escalation of GSK3145095 will begin at
least one level below the highest dose shown to have an acceptable toxicity profile in at
least 3 subjects in Part 1. Part 2 may be conducted in a broader population of selected solid
tumors using a combination of escalating doses of GSK3145095 and 200 mg pembrolizumab. Part 3
will enroll subjects treated with one or more dose levels of GSK3145095 in combination with
200 mg pembrolizumab. Part 4 will investigate the combination of additional anticancer agents
with one or more doses of GSK3145095 identified as safe in Part 1. Up to approximately 220
subjects will be treated in the study. Parts 1 and 2 will each treat up to approximately 30
subjects. Parts 3 and 4 will treat up to approximately 160 subjects (up to 80 subjects in
each Part). The total duration of the study is expected to last up to 2 years.

Inclusion Criteria:

- Subjects must provide signed, written informed consent.

- Male and female subjects, age >=18 years (at the time consent is obtained). a) Male
subjects are eligible to participate if they agree to the following during the study
treatment period and for at least 15 days (Part 1) and 120 days (Parts 2-4) after the
last dose of study treatment: Refrain from donating sperm, be abstinent from
heterosexual or homosexual intercourse as their preferred and usual lifestyle
(abstinent on a long term and persistent basis) and agree to remain abstinent or must
agree to use contraception/barrier: male condom and female partner to use an
additional highly effective contraceptive method with a failure rate of <1 percent per
year. b) female subjects are eligible to participate if they are not either pregnant
or breastfeeding, and at least one of the following conditions applies: is not a woman
of childbearing potential (WOCBP), is a WOCBP and using a contraceptive method that is
highly effective (with a failure rate of <1 percent per year), with low user
dependency during the study treatment period and for at least 15 days (Part 1) and 120
days (Parts 2-4) after the last dose of study treatment and agrees not to donate eggs
(ova, oocytes) for the purpose of reproduction during this period. The investigator
should evaluate the effectiveness of the contraceptive method in relationship to the
first dose of study treatment. Hormonal contraception may be susceptible to
interaction with the study drug, which may reduce the efficacy of the contraceptive
method. Therefore, a barrier method is also required for subjects using a hormonal
option (including hormonal intrauterine device [IUD], oral contraceptive pills/ patch/
vaginal inserts, and hormonal implants) and both highly effective methods of
contraception should be utilized during the treatment period and for at least 15 days
(Part 1) and 120 days (Parts 2-4) after the last dose of study treatment.If a highly
effective non-hormonal method is used, then only one method of contraception is
required (by a female participant or partner of a male participant; in either
situation the male partner must still use a male condom in addition) during the
treatment period and for at least 15 days (Part 1) and 120 days (Parts 2-4) after the
last dose of study treatment. A WOCBP must have a negative highly sensitive pregnancy
test (urine or serum) as required by local regulations) within 24 hours before the
first dose of study intervention. If a urine test cannot be confirmed as negative
(e.g., an ambiguous result), a serum pregnancy test is required. In such cases, the
subject must be excluded from participation if the serum pregnancy result is positive.
If the subject hasn't been on an acceptable method of contraception for at least 2
weeks prior to start of therapy, pregnancy testing must be done weekly for the first
month of treatment. Additional requirements for pregnancy testing during and after
study treatment. The investigator is responsible for review of medical history,
menstrual history, and recent sexual activity to decrease the risk for inclusion of a
woman with an early undetected pregnancy.

- Histological documentation of locally advanced, recurrent or PDAC (Part 1), non-small
cell lung cancer (NSCLC), triple negative breast cancer (TNBC), or melanoma (Part 2)
that has progressed after standard therapy appropriate for the specific tumor type, or
for which standard therapy has proven to be ineffective, intolerable, or is considered
inappropriate. Subjects should have received at least one, but not more than 2 prior
lines of therapy for advanced disease including both standards of care and
investigational therapies. Subjects whose cancers harbor molecular alterations for
which targeted therapy is standard of care should have received health
authority-approved appropriate targeted therapy for their tumor types before
enrollment.

- All subjects in Parts 1 and 2 must consent to provide a fresh biopsy during screening
of a primary tumor lesion or from other metastases (e.g. liver, lung, etc.), and a
second biopsy after approximately 5 weeks of treatment.

- Measurable disease per RECIST version 1.1. Palpable lesions that are not measurable by
radiologic or photographic evaluations may not be utilized as the only measurable
lesion. Subjects are encouraged to provide a pre-Baseline scan (within 24 weeks before
the Baseline scan) to support exploratory investigation of tumor growth kinetics.

- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 to 1.

- Life expectancy of at least 12 weeks.

- Adequate organ function.

- QT duration corrected for heart rate by Fridericia's formula (QTcF) <450 milliseconds
(or QTcF <480 milliseconds for subjects with bundle branch block).

Exclusion Criteria:

- Prior treatment with the following agents: Agents affecting tumor associated
macrophage function or number, including but not limited to inhibitors of
Receptor-interacting protein 1 (RIP1), Receptor-interacting protein 3 (RIP3), Colony
stimulating factor 1 receptor (CSFR-1), C-C chemokine receptor type 2 (CCR2), and
Cluster of differentiation 40 (CD40). Other anticancer therapy, including
chemotherapy, targeted therapy, and biological therapy, within 14 days or 5 half-lives
(from last dose of prior treatment to first dose of GSK3145095), whichever is shorter.
Prior radiation therapy is permissible if at least one non-irradiated measurable
lesion is available for assessment via RECIST version 1.1. No washout after palliative
radiation is required. Investigational therapy within 14 days or 5 half-lives (from
last dose of prior treatment to first dose of GSK3145095), whichever is shorter.

- Malignancy other than disease under study, except as noted: Subject with any other
malignancy from which the subject has been disease-free for more than 2 years and, in
the opinion of the principal investigators and GlaxoSmithKline (GSK) Medical Monitor,
will not affect the evaluation of the effects of this clinical trial treatment on
currently targeted malignancy, can be included in this clinical trial.

- Major surgery <=4 weeks before the first dose of study treatment. Subjects must have
also fully recovered from any surgery (major or minor) and/or its complications before
initiating study treatment.
