Summary:
The objective of this study is to compare the efficacy and safety of MRG003 versus
cetuximab/methotrexate as second/third line of therapy in patients with RM-SCCHN who have
previously failed PD-1 (L1) inhibitors and platinum-based therapy.
Detailed description:
This is a randomized, open-label, multicenter Phase III study to compare the efficacy and
safety of MRG003 versus cetuximab/methotrexate as second/third line of therapy in
patients with RM-SCCHN who have previously failed PD-1 (L1) inhibitors and platinum-based
therapy. Approximately 180 patients will be enrolled, randomized, and stratified
according to the following: Eastern Cooperative Oncology Group Performance Status (ECOG
PS, 0 vs 1) and prior treatment with anti-EGFR mAb (yes vs no). For patients in the
control group, cetuximab will be selected as comparator if no prior treatment with
anti-EGFR mAb; otherwise, methotrexate will be selected.
After signing the informed consent and screened per inclusion/exclusion criteria,
eligible patients will be randomized at a ratio of 1 : 1 and treated with MRG003 (2.3
mg/kg, IV, d1, Q3W) or cetuximab (400 mg/m2 for the first week and 250 mg/m2 for
subsequent weeks, QW) / methotrexate (40 mg/m2, IV, QW) until disease progression, death,
intolerable toxicity, withdrawal of consent, initiation of a new anti-tumor therapy, or
other reasons leading to treatment discontinuation as specified by protocol.
Criteria for eligibility:
Criteria:
Inclusion Criteria:
-
1. Understands and provides written informed consent and willing to follow the
requirements specified in protocol.
2. Age: ≥18 years and ≤75 years. 3. Life expectancy: ≥3 months. 4. Must have
histologically or cytologically confirmed recurrent or metastatic squamous cell
carcinoma of the head and neck (including oral cavity, oropharynx, hypopharynx,
larynx) who had previously failed PD-1 (L1) inhibitors and platinum-based therapy
(in combination or sequential). Prior therapies should be no more than 2 lines.
Note: If disease progression occurred during neoadjuvant/adjuvant treatment or concurrent
radiotherapy, or within 6 months after treatment discontinuation, the anti-tumor
therapies (including platinum-based chemotherapy, anti-EGFR monoclonal antibody, PD-1
(L1) inhibitors, etc.) during neoadjuvant/adjuvant treatment or concurrent radiotherapy
is counted as one line of prior treatment. Discontinuation or dose reduction of one drug,
or change of platinum- or fluorouracil-based agents or PD-1 (L1) inhibitors without
disease progression is considered as the same line of treatment.
5. Must have at least one measurable lesion per RECIST v1.1. Previously irradiated
lesion cannot be considered as target unless there is documented progression three
months after the last treatment of radiotherapy.
6. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 (Appendix 1)
with no deterioration within 2 weeks prior to enrollment.
7. Adequate bone marrow function, defined as meeting all of the following criteria and
having no transfusion therapy within 3 weeks (21 days) or growth factors (G-CSF,
EPO, etc.) support within 2 weeks (14 days) prior to dosing:

• Absolute neutrophil count (ANC) ≥ 1,500/mcL (1.5 × 109/L)

defined as all of the following:
• Total bilirubin (TBIL) ≤ 1.5×ULN;
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5×ULN if no
liver metastasis; ALT or AST ≤ 3.0×ULN in the presence of liver metastasis;
• Alkaline phosphatase (ALP) ≤ 1.5×ULN; ≤ 2×ULN in the presence of liver metastasis;
• Serum albumin ≥ 30 g/L 9. Coagulation: International Normalized Ratio (INR) or
prothrombin time (PT), activated partial thromboplastin time (APTT) ≤ 1.5×ULN (unless
patient is receiving anticoagulant therapy whose anticoagulant level should be within the
therapeutic range). The laboratory parameters should be closely monitored by investigator
if the patient is on anticoagulation therapy.
10. Adequate renal function, defined as Creatinine ≤ 1.5×ULN or creatinine clearance
rate (Ccr) ≥ 50 mL/min if Creatinine > 1.5×ULN (Creatinine clearance is calculated
using the modified Cockcroft-Gault equation. Creatinine clearance can be calculated
as Ccr = [(140-age) × body weight (kg) × (0.85 for women only)]/(72 × serum
creatinine) if no local guidelines are available (without significant electrolyte
imbalance that is not easily corrected).
11. Baseline Left Ventricular Ejection Fraction (LVEF) ≥ 50% measured by multiple-gated
acquisition (MUGA) or echocardiogram (ECHO).
12. A negative serum or urine pregnancy test within 7 days prior to the first dose of
study treatment (females of childbearing potential). If urine pregnancy test is
positive or cannot be confirmed as negative, a confirmatory serum pregnancy test is
required.
13. Patients, both females and males, of reproductive potential must agree to use
adequate contraception during study treatment and for 180 days after the last
treatment.
1. Females of childbearing potential (who are not surgically sterile or postmenopausal
for < 1 year) who are willing to use adequate and reliable contraception such as
avoidance of heterosexual activity, sterilization, oral contraceptives, injectable
contraceptives, intrauterine devices, condoms, etc., during the study until 180 days
after the last dose of study drug.
2. Male patients who are willing to use latex condoms during any sexual contact with
females of childbearing potential during treatment until 180 days after the last
treatment, even if vasectomy has been successfully performed. Reservation of semen
specimen prior to the first dose of study treatment is recommended for fertile males
for potential future conception.
