• Brief Summary: HS-CA102N-103 is a Phase 2, randomized, open label study to evaluate efficacy, safety, and tolerability of CA102N combined with trifluridine/tipiracil (TAS-102) compared to bevacizumab combined with TAS-102 in subjects with metastatic colorectal cancer (mCRC) who failed the standard treatment (for eg, cancer that has relapsed after or is refractory to fluoropyrimidine, oxaliplatin and irinotecan-based chemotherapy).

Detailed Description

HS-CA102N-103 is a Phase 2, randomized, open label study to evaluate efficacy, safety, and tolerability of CA102N combined with trifluridine/tipiracil (TAS-102) compared to bevacizumab combined with TAS-102 in subjects with metastatic colorectal cancer (mCRC) who failed the standard treatment (for eg, cancer that has relapsed after or is refractory to fluoropyrimidine, oxaliplatin and irinotecan-based chemotherapy).

In this study, the safety, tolerability, and PFS of CA102N in combination with TAS-102 compared to bevacizumab combined with TAS-102 will be evaluated in up to 100 subjects with metastatic colorectal cancer who have previously received fluoropyrimidine, oxaliplatin, and irinotecan-based chemotherapy, an anti-vascular endothelial growth factor (VEGF) biological therapy, and if RAS wild-type mCRC, an anti-epidermal growth factor receptor (EGFR) therapy.

• Study Type: Interventional
• Study Phase: Phase 2

Study Design

Allocation: Randomized

Intervention Model Description:

Up to 100 subjects will be enrolled in this study (including drop-out subjects), with 50 subjects assigned to each treatment arm.

For arm 1, subjects will receive the assigned dose level of CA102N in combination with trifluridine/tipiracil (TAS-102). For Arm 2, subjects will receive bevacizumab in combination with trifluridine/tipiracil (TAS-102)

Masking: None (Open Label)
Primary Purpose: Treatment

• Condition: Metastatic Colorectal Cancer

Intervention

• Drug: CA102N
  CA102N is a covalently bound conjugate of the biological polymer sodium hyaluronate (NaHA) and nimesulide (Nim)

• Drug: TAS-102
  TAS-102 is a cytotoxic combination treatment of 2 drugs: trifluridine, a thymidine-based nucleoside analogue, and tipiracil an inhibitor of thymidine phosphorylase.

• Ascites, pleural effusion, or pericardial fluid requiring drainage in last 4 weeks prior to Screening, or subject who continues to have a peritoneal/pleural/pericardial drainage catheter post-surgery at the time of informed consent signature.
• History of allogeneic transplantation requiring immunosuppressive therapy.
• Presence of uncontrolled infections.
• Known positive test for hepatitis B, hepatitis C or human immunodeficiency virus. Testing is not required for protocol eligibility. Subjects who have received curative therapy for HCV with no detectable viral load are not excluded.
• Has clinically active brain metastases, defined as untreated and symptomatic, or requiring therapy with steroids or anticonvulsants to control associated symptoms. Subjects with treated brain metastases that are no longer symptomatic and who require no treatment with steroids and stable brain metastases at least 3 months may be included in the study if they have recovered from the acute toxic effect of radiotherapy.
• Pregnant or breast feeding or intends to become pregnant during the study.
• Unresolved toxicity of greater than or equal to NCI-CTCAE (version 5.0) Grade 2 attributed to any prior therapies (excluding anemia, alopecia, skin pigmentation, and platinum-induced peripheral neurotoxicity).
