This is a phase I, open-label, multicenter study in adult patients with advanced solid tumors that have progressed despite standard therapy or for which no standard therapy exists. DN1508052-01 will be administered subcutaneously on Day 1, Day 8 and Day 15 in 28-day cycles. Other dose regimens may be explored based on the analysis of emerging PK, pharmacodynamics (PD) and safety data. This study is designed to determine the MTD, RP2D and investigate the safety, tolerability, PK, biomarkers, HPV status and ISR in DN1508052-01-treated patients.
Condition or disease
Advanced Solid Tumors
Study Population is adult patients (≥18 years) with histologically or cytologically confirmed, unresectable advanced solid tumors that have progressed despite standard therapy or for which no standard therapy exists.The selected starting dose, 0.01 mg/m2 of DN1508052-01, SC, on Day 1, Day 8 and Day 15 of each cycle.The starting dose will proceed with one patient. The next dose 0.1 mg/m2 will be explored if safety data permit in that there is no instance of a ≥ Common Terminology Criteria for Adverse Event (CTCAE v5.0) Grade 2 AE that is at least possibly related to the study intervention.then Dose escalation will then proceed following the 3+3 cohorts design.Dose escalation will continue until MTD or RP2D is reached, or the dose escalation will be terminated at the discretion of Investigators and Sponsor (or its designee) based on the analyses of emerging PK, PD, safety and efficacy data.The Primary objective is to determine the maximum tolerated dose (MTD) and recommended phase Ⅱ dose (RP2D) and assess dose-limiting toxicity (DLT) of DN1508052-01 as a single agent when administered subcutaneously to adult patients with advanced solid tumors.
A Phase Ⅰ, Multi-Center, Open-Label Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Antitumor Activity of DN1508052-01 as a Single Agent When Administered Subcutaneously to Adult Patients With Advanced Solid Tumors

Layout table for eligibility information
Ages Eligible for Study:
18 Years and older (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Age 18 years or older;
Patients with histologically or cytologically confirmed, unresectable advanced solid tumors that have progressed despite standard therapy or for which no standard therapy exists;
Patients must have at least one measurable lesion as defined by RECIST v1.1;
ECOG performance score 0 or 1;
Life expectancy ≥ 3 months;
Patients who have sufficient Baseline organ function and whose laboratory data meet the following criteria at enrollment:
Absolute neutrophil count （ANC）≥1.5 × 109/L;
Platelets ≥100 × 109/L;
Serum bilirubin ≤1.5 × upper limit of normal (ULN) or ≤ 3×ULN in any subject with Gilbert's Syndrome; Aspartate aminotransferase（AST） and alanine aminotransferase（ALT） ≤2.5 × ULN without liver metastases, or ≤5 × ULN if the patient has documented liver metastases;
International normalization ratio ≤1.2 if the patient is not on anticoagulants, or ≤3 if the patient is on anticoagulants;
Women of childbearing potential must have a negative serum pregnancy test prior to study entry, and agree to use adequate contraception from study entry through at least 1 month after the last dose of study drug. A female patient of nonchildbearing potential will have had at least 12 continuous months of natural (spontaneous) amenorrhea, follicle stimulating hormone level ≥40 mIU/mL at Screening, and an appropriate clinical profile (e.g., age appropriate, history of vasomotor symptoms), or have had surgical bilateral oophorectomy, hysterectomy, or tubal ligation ≥6 weeks prior to Screening; in the case of oophorectomy alone, reproductive status will be confirmed by hormone level assessment;
A male patient must agree to use adequate contraception (male condom with spermicide or provide evidence of successful vasectomy; sterile sexual partner; or female sexual partner who uses an intrauterine device with spermicide, a female condom with spermicide, a contraceptive sponge with spermicide, an intravaginal system, a double diaphragm with spermicide, a cervical cap with spermicide) from study entry through at least 1 month after the last dose of study drug;
Patients must provide written informed consent prior to any study procedures.
Patients with symptomatic central nervous system (CNS) metastases or carcinomatous meningitis; Note: Patients with treated CNS metastases may participate in this trial if the patient has completed radiotherapy or surgery for CNS metastases >2 weeks prior to study entry and if the patient is neurologically stable ≥ 2 weeks (no new neurologic deficits from brain metastasis on Screening clinical examination, no new findings on CNS imaging, and no corticosteroids being used).
Patients who have a history of another primary malignancy, with the exception of locally excised non-melanoma skin cancer and carcinoma in situ of uterine cervix. A patient who has had no evidence of disease from another primary cancer for 3 or more years is allowed to participate in the study;
Patients who have a known history of active hepatitis C or chronic hepatitis B ("active hepatitis" defined as HCV RNA level ≥ 103 copies/mL for hepatitis C or HBV DNA level ≥ 104 copies/mL for hepatitis B at Screening);
