INDP-D101 (primary)
NCI-2022-10991
Summary
INDP-D101 is a Phase 1, open-label, multi-center, dose escalation and expansion study
evaluating the safety, tolerability and clinical activity of Decoy20 in patients with
locally advanced or metastatic solid tumors.
Objectives
Decoy20, is a novel, systemically administered multiple Toll-like receptor (TLR)
agonist-based cancer immunotherapy.
INDP-D101 is a Phase 1, open-label, multi-center, 3+3 dose escalation and expansion study
evaluating the safety, tolerability and clinical activity of Decoy20 in subjects with
advanced solid tumors. The study will include 3 parts:
In Part 1, Subjects will receive a single dose of Decoy20 at one of up to seven assigned
dose levels on Week 1 Day 1 (SAD). Subjects will be observed for 28 days for dose
limiting toxicity. Safety will be assessed by a safety review committee (SRC), comprised
of investigators and the study sponsor, and subsequently will recommend the dose of
Decoy20 to take forward.
Part 2 will begin when the single dose recommended from Part 1 is identified and it will
confirm the safety of weekly administration of Decoy20 in approximately 54 to 90
subjects. More than one dose may be studied in Part 2 that is at or below the MTD
determined in Part 1. Eligible subjects must have one of the following locally advanced
or metastatic tumor types: hepatocellular carcinoma (HCC), colorectal cancer (CRC) with
liver metastasis, urothelial cancer, squamous cell carcinoma of the head and neck
(SCCHN), adenocarcinoma of the pancreas, non-small cell lung cancer (NSCLC). Part 2 is
further divided into 2 parts a Safety Run-In (Part 2a) and a Dose Expansion (Part 2b).
Part 2a will enroll 6 subjects in a staggered manner, and each subject will receive 4
weekly doses of Decoy20 identified in Part 1. Safety data for each of these subjects will
be collected for 4 weeks after the subjects' 4th Decoy20 dose for acute and delayed
toxicity. This data will be reviewed by the SRC and the determination of the Decoy20 dose
for Part 2b made.
Part 2b will further evaluate and confirm the safety and preliminary efficacy of
continuous weekly Decoy20 administration for up to 1 year. The SRC will continue to meet
and review data on an ongoing or ad-hoc basis during Part 2b of the study to ensure that
there are no undue risks to study subjects and to confirm the RP2D and regimen.
Eligibility
- Males or females, age 18 years or older.
- Histologically confirmed diagnosis of locally advanced or metastatic solid tumor. For Part 2, subjects must have one of the following locally advanced or metastatic tumor types: hepatocellular carcinoma (HCC), colorectal cancer (CRC) with liver metastasis, urothelial cancer, squamous cell carcinoma of the head and neck (SCCHN), adenocarcinoma of the pancreas, non-small cell lung cancer (NSCLC).
- Subject must have exhausted all available therapy or have declined treatment or treatment is contraindicated. Subjects with tumors that have known actionable molecular alteration such as EGFR, ALK, ROS-1, BRAF, RET, MET, and KRAS must have progressed on directed molecular therapy.
- Measurable disease (at least 1 measurable lesion) per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 as defined by tumor type.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Life expectancy of at least 3 months.
- Female subjects must be of non-childbearing potential (surgically sterile or at least 2 years postmenopausal) or agree to use a highly effective contraception method while receiving treatment with Decoy20 and for 30 days after the last dose of Decoy20.
- Male subjects must utilize reliable contraceptive precautions for the duration of Decoy20 treatment and 30 days after the last dose of Decoy20.
- Adequate organ function as demonstrated by baseline laboratory assessment
- Left ventricular ejection fraction (LVEF) = 45% by echocardiogram (ECHO) or multi gated acquisition scan (MUGA).
- Recovered from toxicities due to prior therapies.
- Willing and able to comply with all scheduled visits, laboratory tests, and other study procedures including mandatory pre-treatment and on-treatment biopsies for subjects enrolled to Part2.

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts...
