  • Other primary malignancies, past or present, except for the enrollment indications of this study. However, this does not include: malignancies that have been cured within 2 years prior to the first dose of SON-DP with no signs of recurrence, fully treated and completely resected cervical carcinoma in situ, completely resected skin basal cell carcinoma or squamous cell carcinoma, any malignancy considered indolent and not requiring treatment, or any type of carcinoma in situ that has been completely resected.
  • The presence of clinically symptomatic, poorly controlled pleural effusion, pericardial effusion, or ascites that requires repeated drainage.
  • Anticancer therapy within 5 half-lives or 3 weeks (whichever is shorter) prior to study entry. Chinese anticancer medicine, three weeks prior first dosing.

Exceptions include: palliative radiation therapy for localized lesions (e.g., radiation therapy for bone lesions aimed at symptom relief) or local interventional treatments (such as transarterial chemoembolization \[TACE\] and others) assessed by the investigator as posing no safety risks.

Intervention Model
SEQUENTIAL
Model Details: Sequential assignment and dose expansion of RP2D in selected tumor types. This is an open-label clinical trial for patients with advanced solid tumors. The design follows an accelerated titration combined with the traditional 3+3 dose escalation rule to ensure the safety of the participants, while also obtaining key information about SON-DP when administering it to subjects who have signed informed consent. In order to minimize the number of participants in dose groups with limited antitumor activity but relatively low toxic side effects. Since the primary objective of this study is to gather information on the antitumor activity of SON-DP and determine the RP2D (Recommended Phase 2 Dose), various methods to assess drug activity have been designed to evaluate the safety, antitumor efficacy, and RP2D of the product.
