Brief Summary: This is a first-in-human multi-center multi-cohort open-label phase IbII study of XmAb22841 CTLA-4 X LAG3 administered in combination with XmAb23104 PD1 X ICOS in participants with a histologically or cytologically confirmed diagnosis of an advancedmetastatic melanoma XmAb22841 CTLA-4 X LAG3 is a bi-specific antibody targeting two different T cell membrane proteins responsible for regulation of T cell activity It offers potential immunologic and safety advantages over existing therapies XmAb22841 CTLA-4 X LAG3 is being evaluated in this clinical study designed to assess the safety tolerability PK and PD of escalating doses of XmAb22841 CTLA-4 X LAG3 administered in combination with XmAb23104 PD1 X ICOS

The study will be conducted through the University of California Melanoma Consortium UCMC
Detailed Description: PRIMARY OBJECTIVES

I Dose Escalation Phase Part 1 To estimate the recommended phase 2 dose RP2D of XmAb22841 CTLA-4 X LAG3 in combination XmAb23104 PD1 X ICOS

II Dose Expansion Phase Part 2 To assess clinical response as measured by objective response rate of patients treated with XmAb22841 CTLA-4 X LAG3 in combination XmAb23104 PD1 X ICOS

SECONDARY OBJECTIVES

I To evaluate the pharmacokinetics PK and anti-drug antibody ADA immunogenicity of XmAb23104 PD1 X ICOS and XmAb22841 CTLA-4 X LAG3 Dose Escalation Part 1 Dose Expansion Part 2

II To evaluate the clinical efficacy of XmAb23104 PD1 X ICOS and XmAb22841 CTLA-4 X LAG3 Dose Expansion Part 2

EXPLORATORY OBJECTIVES

I To identify molecular genomic metabolic andor proteomic biomarkers that may be indicative of clinical responseresistance safety pharmacodynamic activity andor the mechanism of action of XmAb22841 CTLA-4 X LAG3 administered in combination with XmAb23104 PD1 X ICOS Dose Escalation Part 1 Dose ExpansionPart 2

OUTLINE

Participants will initially be enrolled in the Dose Escalation Phase Part 1

PHASE 2 Dose Expansion Part 2 will not be initiated

Participants may continue trial therapy until the earlier of radiographic disease progression withdrawal unacceptable toxicity completion of 24 cycles of XmAb23104 PD1 X ICOS or other treatment discontinuation due to unacceptable toxicity participant withdrawal progressive disease or death The entire treatment duration of twenty-four 28-day cycles is approximately 2 years After discontinuing trial therapy participants will be followed for toxicity response and overall survival every 12 weeks for up to 5 years from initiation of study treatment
