简要总结
This study is an open-label, Phase 1, multicenter study to evaluate the safety, tolerability, PK, and PD profiles of AGEN2373 as a monotherapy and in combination with botensilimab (also known as AGEN1181), and to assess the maximum tolerated dose (MTD) in subjects with advanced solid tumors.
详细描述
This Phase 1 study will enroll up to approximately 200 evaluable adult patients with a histologically confirmed diagnosis of advanced cancer for which no standard therapy is available or standard therapy has failed, regardless of diagnosis and prior therapies. This also includes patients with PD-1/PD-L1 R/R melanoma. Patients may be enrolled into one of 5 treatment arms:
2-Week AGEN2373 monotherapy
3-Week AGEN2373 monotherapy
4-Week AGEN2373 monotherapy
Combination of AGEN2373 and botensilimab in patients with programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) relapsed/refractory (R/R) melanoma.

- •Patients must provide a sufficient and adequate formalin-fixed paraffin-embedded tumor tissue sample (biopsy) collected after the last dose of prior anti-cancer therapy and before the first dose of study treatment from a site not previously irradiated and agree to mandatory on-treatment biopsy if clinically feasible.
- •Female patients of childbearing potential must have a negative serum pregnancy test at screening (within 72 hours of first dose of study medication). Non-childbearing potential is defined as 1 of the following:
- •≥ 45 years of age and has not had menses for > 1 year
- •Amenorrheic for > 2 years without a hysterectomy and oophorectomy and follicle-stimulating hormone value in the postmenopausal range upon prestudy (screening) evaluation
- •Status is post-hysterectomy, -bilateral oophorectomy, or -tubal ligation
- •Female patients of childbearing potential must be willing to use highly effective contraceptive measures starting with the Screening Visit through 90 days after last dose of study treatment. Note: Abstinence is acceptable if this is the established and preferred contraception method for the patient.
- •Male patients with a female partner(s) of childbearing potential must agree to use highly effective contraceptive measures throughout the study starting with the Screening Visit through 90 days after the last dose of study treatment is received. Males with pregnant partners must agree to use a condom; no additional method of contraception is required for the pregnant partner. Note: Abstinence is acceptable if this is the established and preferred contraception method for the patient.

- •Note: Patients with BRAF V600-positive tumors with no clinically significant tumor-related symptoms nor evidence of rapidly progressive disease are not required to be treated with a BRAF inhibitor (alone or in combination with a MEK inhibitor) based on Investigator's decision.
排除标准
- •Currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigation device within 3 weeks of first dose of current study treatment.
- •Received prior systemic cytotoxic chemotherapy, biological therapy, radiotherapy, or major surgery outside of the acceptable washout period prior to first dose of study drug. A 1-week washout is permitted for palliative radiation to non-central nervous system (CNS) disease, with Sponsor approval.
- •The following washout windows are acceptable from prior treatments (i.e., patients with time periods less than the following should be excluded):

Note: Patients with history of brain metastases that have been treated may participate provided they show evidence of stable supra-tentorial lesions at screening (defined as 2 brain images, both of which are obtained after treatment to the brain metastases and obtained ≥ 4 weeks apart). In addition, any neurologic symptoms that developed either as a result of the brain metastases or their treatment must have returned to baseline or resolved. Any steroids administered as part of this therapy must be completed ≥ 3 days prior to first dose of study medication.
