Official Title

Phase Ib/II Clinical Study Evaluating the Safety, Pharmacokinetics, and Preliminary Efficacy of TQB2922 Injection (Subcutaneous) in the Treatment of Recurrent/Metastatic Head and Neck Cancer

Brief Summary

This study is a Phase Ib/II study of TQB2922 injection (subcutaneous). In the Phase Ib stage, a 3+3 dose-escalation design was used to determine the RP2D and pharmacokinetic characteristics of TQB2922 injection (subcutaneous) administered once every 3 weeks in subjects with R/M HNC. The Phase II stage explored the efficacy and safety of TQB2922 (subcutaneous) as monotherapy or in combination therapy in subjects with R/M HNC.

• Females of childbearing potential agree to use effective contraception during the study and for 6 months after study completion; serum or urine pregnancy test must be negative within 7 days prior to enrollment. Males agree to use effective contraception during the study and for 6 months after study completion (see Section 5.5 for details).

Additional criteria for Expansion Cohort 1 and Cohort 2:

• Has received at least one line of systemic therapy for recurrent/metastatic disease, including platinum-based chemotherapy and anti-programmed cell death protein 1 / programmed cell death ligand 1 (anti-PD-1/L1) therapy.

Systemic therapy administered as part of multimodal treatment for locally advanced disease (including neoadjuvant/induction, concurrent, adjuvant/consolidation therapy), with disease recurrence or progression during chemotherapy/immunotherapy or within 6 months after the last dose, shall be defined as first-line chemotherapy/immunotherapy failure.

• No prior exposure to paclitaxel and its novel formulations (e.g., albumin-bound paclitaxel) (Cohort 2 only).

Additional criteria for Expansion Cohort 3

• No prior systemic therapy for recurrent/metastatic disease. Systemic therapy as part of multimodal treatment for locally advanced disease (including induction/neoadjuvant therapy, concurrent systemic therapy with curative radiotherapy, adjuvant/consolidation therapy) is excluded, provided that the interval from completion of such therapy to disease recurrence/progression exceeds 6 months.

Exclusion Criteria:

• Current or history of other malignant tumors. The following two conditions are allowed for enrollment:

Other malignant tumors treated with surgery alone with continuous 5-year disease-free survival (DFS); cured carcinoma in situ of cervix, non-melanoma skin cancer and superficial bladder tumors [Ta (non-invasive tumor), Tis (carcinoma in situ) and T1 (tumor invading basement membrane)].

• Diseases that interfere with subcutaneous injection or venous blood collection.
• Adverse reactions from prior treatment have not recovered to ≤Grade 1 per CTCAE Version 6.0, except Grade 2 alopecia, Grade 2 peripheral neurotoxicity (Cohort 1 only), Grade 2 anemia, non-clinically significant asymptomatic Grade 2 laboratory abnormalities, hypothyroidism stabilized by hormone replacement therapy, and other toxicities deemed to have no safety risk by the investigator.
• Major surgical treatment, significant traumatic injury within 4 weeks prior to the first dose, or planned major surgery during the study treatment period (excluding protocol-specified surgeries); or unhealed wounds or fractures for a long time.

Major surgery is defined as Grade 3 or above surgeries in the 2022 National Surgery Classification Catalogue.

• Arterial/venous thromboembolic events within 6 months prior to the first dose, including cerebrovascular accidents (including transient ischemic attack, excluding lacunar cerebral infarction). Implantable venous port/catheter-related thrombosis or superficial venous thrombosis shall not be regarded as "severe" thromboembolism); deep venous thrombosis and pulmonary embolism.
• Active and poorly controlled viral hepatitis. Subjects meeting the following criteria may undergo screening:

HBsAg-positive subjects must have Hepatitis B Virus Deoxyribonucleic Acid (HBV) DNA <500 IU/mL (or 2500 copies/mL), and agree to receive anti-HBV therapy throughout the study.

HCV-infected subjects (HCV Ab or HCV RNA positive): HCV viral RNA ≤upper limit of normal, and continue approved antiviral therapy during the study.

• Active syphilis requiring treatment.
