A Phase I Dose Escalation and Expansion Study to Evaluate the Safety, Tolerability, Efficacy, Pharmacokinetics, and Pharmacodynamics of SON-DP in Subjects with Advanced Solid Tumors
Read the detailed description
- SON-DP is different from the conventional cancer cell-killing therapy which have high side effect, drug resistance, cancer recurrence and tumor heterogenicity, SON-DP is a novel transcription factor (TF) protein anticancer drug to treat the Participants with relapsed and advanced metastatic solid tumors. Proposed as an effective therapeutic drug product for a cell-converting cancer therapy, SON-DP is expected to transform cancer cells in situ into normal tissue cells via a SON-DP induced cancer cell reprogramming and re-differentiation process as an innovative rationale.
- SON-DP is developed based on the rationale of cancer cell conversion into normal tissue cells as the primary mechanism of actions of a new cancer therapy, not by cancer cell-killing, the traditional goals of chemotherapy, radiation therapy, targeted therapy and immune therapy. Cancer cell conversion is achieved by the SON-DP induced pluripotent re-programming in situ inside tumor tissue into transient iPSCs (tiPSCs) that quickly re-differentiate into normal tissue cells induced by the differentiating resident tissue environment. The in situ generated tiPSCs either secrete exosomes, providing the embryonic stem cells (ESC)-like microenvironments to transform the surrounding cancer cells into normal tissue cells for an overall malignant phenotype reversion (OMPR) (an effect named as a bystander effect), or display a targeting effect that enables the in situ generated tiPSCs to track down the distant metastatic cancer cells for OMPR (an effect named as a tropism effect). The SON-DP-induced cell reprogramming also restored the mutation-caused and compromised p53 checkpoint in cancer cells to re-establish cell quality control system that ensures the downstream re-differentiation of the in situ generated tiPSCs into normal tissue cells. Overall, this SON-DP-induced re-programming and re-differentiation process is capable of transforming both primary and metastatic cancer cells into normal tissue cells.
- Preclinical studies demonstrated that treatment of tumors with SON-DP resulted in eradication of late-stage cancers and long term (over 3 years) survival without teratoma formation and cancer recurrence in multiple tumor-bearing mouse/rat (syngeneic) or human xenograft rodent models, providing high treatment efficacy of this cell-converting cancer therapy. Thus, the cell-converting cancer therapy rationale represents a new cancer therapeutic strategy. SON-DP was tolerated in tumor-bearing rodents, as well as in naïve rats, dogs, and monkeys as demonstrated by GLP-enabled (rats and dogs) and non-GLP (monkey) toxicity study and after repeated IV administrations at higher doses compared with the planned clinical dose range. Therefore, the current nonclinical studies, including pharmacodynamics (PD), pharmacokinetics (PK) and toxicology studies, support the safety and efficacy of SON-DP TF protein drug product to be used in clinical studies of human participants. This clinical study will be conducted in selected types of relapsed/refractory advanced/metastatic solid tumors as a step in demonstrating the utility of this anticancer agent.
- In this SON-DP-A003-ST clinical trial, SON-DP is given to the participants with late stage solid tumors through 150-minutes IV infusion once a week at 4 dose levels during the first Phase I dose escalation to find the recommended phase II dose (RP2D) for the second Phase Ib does expansion stage that will focus on 2 cancer types including advanced primary liver cancer and advanced primary gastric cancer.
- During Phase Ia dose escalation stage, an 3+3 design will be followed. Phase Ia will enroll the participants with various types of solid tumors that metastasized and not response to standard treatment.
- During Phase Ib dose expansion stage, SON-DP will be used, at RP2D dose level, to treat the participants with 2 specific cancer types including advanced primary liver cancer and advanced primary gastric cancer. Two groups of cancer cohorts will be opened with eligible participants who have relapsed/refractory/intolerant to standard of care therapies of these two advanced/metastatic solid tumors. Participants will be followed for safety, confirmation of the RP2D, PK, PD, and anti-tumor activity as measured by standard assessment tools.

- For Phase Ia: Participants with histologic diagnosis and confirmed solid tumor; For Phase Ib: Participants with one of the two tumor types: Group 1: advanced primary liver cancer; Group 2: Advanced primary gastric cancer (including gastroesophageal junction adenocarcinoma).
- There must be at least one measurable lesion defined by RECIST v1.1. Lesions intended for biopsy should generally not be selected as target lesions, unless the investigator assesses that the biopsy of the lesion will not affect subsequent tumor evaluations. Lesions that have previously undergone radiation therapy, interventional therapy, or other local treatments should generally not be selected as target lesions, unless the lesion shows clear radiological progression after local treatment.
- The ECOG performance status ≤ 1.
- Able to understand and willing to sign the informed consent form (ICF) and comply with all the requirements of the protocol.
Key exclusion criteria (27 listed)
- Pregnant or breastfeeding women. Pregnancy is defined as the state from conception until the termination of pregnancy, confirmed by a positive human chorionic gonadotropin (hCG) laboratory test. Unless one of the following criteria is met: permanent sterilization (hysterectomy, bilateral salpingectomy, or bilateral oophorectomy), or documented biological or physiological evidence of postmenopausal status (defined as no menstruation for more than 12 months without other conditions), or women who have been menopausal for 6-12 months must have a serum follicle-stimulating hormone (FSH) level > 40 mIU/mL to confirm menopause; otherwise, female subjects will be considered fertile.
- Participation in an interventional, investigational study within 2 weeks or 5 half-lives, whichever is shorter of the first dose of study treatment.
- Presence of overt leptomeningeal or active central nervous system (CNS) metastases or primary tumors or CNS metastases that require local CNS-directed therapy (e.g., radiotherapy or surgery) or increasing doses of corticosteroids within the prior 2 weeks.
- Impaired cardiac function or clinically significant cardiac disease, including any of the following:
- Uncontrolled hypertension (systolic blood pressure >160 mmHg and diastolic blood pressure >100 mmHg), or in the opinion of the Investigator: a recent history of hypertension crisis, or a recent history of hypertensive encephalopathy.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
