A First-in-Human Study of HH160 in Patients With Advanced Solid Tumors

May 29, 2026 updated by: Huahui Health

An Open-Label, Multicenter, Phase 1 Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, Immunogenicity and Preliminary Antitumor Activity of HH160 in Patients With Advanced Solid Tumors

This study is evaluating the safety, side effects, how the body processes HH160, and its early anticancer activity when given alone or with other cancer treatments in participants with advanced solid tumors. The study will also identify the recommended dose for future studies. The trial includes two phases and is expected to last about 4 years, with treatment and follow-up lasting approximately 6-12 months each.

Detailed Description

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), immunogenicity, pharmacodynamics (PD), and preliminary antitumor activity of HH160 alone or in combination with antitumor agents in participants with advanced or solid tumors, including non-small cell lung cancer (NSCLC), hepatocellular carcinoma (HCC), colorectal cancer (CRC), gastroesophageal adenocarcinoma (GEA), head and neck squamous cell carcinoma, renal cell carcinoma (RCC), endometrial carcinoma, cervical cancer, ovarian cancer, small cell lung cancer, triple-negative breast cancer, urothelial carcinoma, and additional tumor types based on emerging clinical data.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Phase 1a Part 1 : Dose Escalation
Participants with advanced solid tumors will receive escalating doses of HH160
Drug: HH160
Administered by intravenous infusion every 3 weeks (Q3W)
Experimental: Phase 1a Part 2: Safety Expansion
Participants with selected advanced solid tumors, including non-small cell lung cancer (NSCLC), hepatocellular carcinoma (HCC), colorectal carcinoma (CRC), and other tumor types, will receive HH160 at dose levels determined to be tolerable during dose escalation to further evaluate safety and tolerability.
Drug: HH160
Administered by intravenous infusion every 3 weeks (Q3W)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
Time Frame: From first dose of study drug to 30 days after last dose or initiation of a new anticancer therapy, whichever occurs first; up to approximately 12 months
Assessed by treatment-emergent adverse events (TEAEs), serious adverse events (SAEs). and adverse events meeting protocol-defined dose-limiting toxicity (DLT) criteria.
From first dose of study drug to 30 days after last dose or initiation of a new anticancer therapy, whichever occurs first; up to approximately 12 months
Maximum Tolerated Dose (MTD) or Maximum Administered Dose (MAD) of HH160
Time Frame: From first dose through the end of Cycle 1 (approximately 1 month)
The MTD or MAD is defined as the highest dose evaluated for which the estimated toxicity rate is closest to the target toxicity rate of 28%, or the highest dose administered, respectively.
From first dose through the end of Cycle 1 (approximately 1 month)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective Response Rate (ORR)
Time Frame: Up to 2 years
Defined as the percentage of participants who achieved complete response (CR) or partial response (PR) as determined by investigator assessment using RECIST v1.1.
Up to 2 years
Disease Control Rate (DCR)
Time Frame: Up to 2 years
Defined as the percentage of participants who achieve a best overall response of complete response (CR), partial response (PR), or stable disease (SD) as determined by investigator assessment using RECIST v1.1.
Up to 2 years
Duration of Response (DOR)
Time Frame: Up to 2 years
Defined as the time from the date that a response (CR or PR) was first observed to the date of first documented disease progression or death, whichever occurred first as determined by investigator assessment using RECIST v1.1.
Up to 2 years
Progression-free Survival (PFS)
Time Frame: Up to 2 years
PFS is defined as time from start of treatment to the first documentation of disease progression or death, whichever occurs first as determined by investigator assessment using RECIST v1.1.
Up to 2 years
Time to Response (TTR)
Time Frame: Up to 2 years
TTR is defined as the time from start of treatment to the first date that response criteria (CR or PR) were met, as determined by investigator assessment using RECIST v1.1.
