Brief summary

The goal of this Phase I/II observational and interventional platform study is to evaluate the safety and efficacy of multiple types of innovative anti-tumor drugs and new technologies in patients with rare solid tumors. The study utilizes multi-dimensional precision screening (including WES, RNAseq, mIHC, and quantitative proteomics) to match patients with specific sub-protocols. Key questions it aims to answer: Assess the safety of innovative therapies in rare tumor populations. Evaluate the objective response rate (ORR) and other efficacy metrics. Explore biomarkers related to therapeutic efficacy. Participants: Patients with metastatic or advanced rare solid tumors who have failed standard therapy or have no standard treatment options.

Detailed description

This is an open-label, non-randomized, multi-arm, single-center Phase I/II platform study (PLATFORM2). Based on the definition of rare tumors in China (incidence \< 2.5/100,000 or specific list), eligible patients will undergo multi-omics screening. Based on the molecular profiling results (gene variations or protein expression), patients will be assigned to corresponding treatment arms (Sub-studies). Therapies include small molecules, protein drugs, Cell and Gene Therapy (CGT) products, and therapeutic vaccines. The study employs a Clopper-Pearson Two-Stage Minimax design for each arm.

BIOLOGICALNK510

NK510 is a first-in-class, base-edited allogeneic natural killer (NK) cell product derived from healthy donor PBMCs. It utilizes RNP-based base editing technology to knock out the TIGIT gene, an inhibitory receptor that binds to CD155 on tumor cells. By eliminating TIGIT-mediated suppression, NK510 enhances intrinsic NK cell antitumor activity and demonstrates improved efficacy against CD155-expressing solid tumors.

DRUGCE120

CE120 is an innovative tumor immunotherapy that utilizes platelet membranes to cloak nanoparticles loaded with the immune activator R848, enabling tumor-targeted delivery via the natural adhesion of platelets to tumor cells. Upon intratumoral injection, CE120 activates local and systemic antitumor immune responses, including the induction of immune memory, to inhibit tumor growth, prevent recurrence, and clear tumors.

GV20-0251 is a monoclonal antibody targeting the highly conserved immunomodulatory protein IGSF8; it blocks the interaction between IGSF8 and its receptors on NK and DC cells, thereby conferring a mechanistic advantage in reversing immune resistance.

DRUGLYC001

LYC001 is a PEG2000-DSPE-stabilized high-affinity IL-2 complex that maintains IL-2 in a uniform bound state, preventing the release of free IL-2 after dilution in body fluids.

DRUGYSCH-01

YSCH-01 is a replication-dual-regulated human adenovirus type 5 vector engineered to selectively replicate in tumor cells and deliver an optimized recombinant pseudo-interferon gene (L-IFN), enabling high-level intratumoral L-IFN expression and secretion; through simultaneous oncolytic viral replication and potent immune stimulation, YSCH-01 achieves a dual antitumor mechanism that directly kills cancer cells while activating robust antitumor immune responses with minimal toxicity to normal tissues.

DRUGBMD006

BMD006 is an inhaled mRNA tumor-associated antigen dry powder vaccine targeting lung cancer and solid tumors with lung metastasis, classified as an off-the-shelf anti-tumor product.

DRUGCREPT-618

CREPT-618 Injection is an investigational nucleic acid-based therapeutic drug developed by Heya (Beijing) Pharmaceutical Technology Co., Ltd. It represents a cutting-edge approach in pharmaceutical technology, falling under the category of small nucleic acid drugs, which are considered a third generation of therapeutics following small molecules and antibodies.
