2. Be ≥ 18 years of age at time of consent
3. For Melanoma Subjects: Have histologically or cytologically confirmed diagnosis of unresectable Stage III or metastatic (Stage IV) melanoma not amenable to local therapy, and irrespective of PD-L1 status
4. For TNBC Subjects: Have histologically or cytologically confirmed diagnosis of metastatic (Stage IV) TNBC, and irrespective of PD-L1 status. TNBC is defined as negative immunohistochemistry (IHC) assays for Estrogen Receptor (ER), and Progesterone Receptor (PR), and HER2 negative (IHC 0 or 1+, or 2+ by IHC confirmed negative by FISH)
5. Have documented objective radiographic or clinical disease progression after PD-1/PD-L1 +/- anti-CTLA-4 inhibitor therapy (melanoma) or after at least 1 line of chemotherapy for metastatic disease (TNBC)
6. Have resolution of all previous treatment-related toxicities to Grade 1 severity or lower, except for stable sensory neuropathy (less than or equal to Grade 2) or alopecia. If subject received major surgery or radiation therapy of \> 30 Gy, must have recovered from the toxicity and/or complications from the intervention.
7. Have at least one radiologically measurable lesion as per RECIST v1.1 defined as a lesion that is at least 10 mm in longest diameter or lymph node that is at least 15 mm in short axis imaged by CT scan or MRI and obtained by imaging within 28 days prior to start of study treatment. Tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
8. Have peripheral blood levels of IgG anti-β-glucan antibody (ABA) of ≥ 20 mcg/mL as determined by an ELISA test within 28 days prior to start of study treatment
9. Be willing to consider providing fresh tissue for biomarker analysis, and, based on the adequacy of the tissue sample quality, for assessment of biomarker status. Repeat samples may be required if adequate tissue is not provided. Newly obtained biopsy specimens are preferred to archived samples and formalin-fixed, paraffin-embedded block specimens are preferred to slides.
Note: Information on 1 tumor biopsy sample is mandatory and is as follows: (1) To determine eligibility, historical (diagnostic) tumor biopsy official pathology report +/- an archival sample. Additional biopsy samples, preferably obtained from the same localized region, are highly desirable when feasible at the following time points: (2) Sample before the first dose of study treatment, (3) Sample after completion of Cycle 2 but before the start of Cycle 3 dosing, and (4) Sample either at the time of response or at the End of Study Visit (if no response).
10. Have Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 (see Appendix 14.3)
11. Have life expectancy of 3 months or greater as determined by the treating physician
12. Have adequate organ function (all screening labs should be performed within 15 days prior to treatment initiation):
1. Total bilirubin ≤ 1.5 × upper limit of normal (ULN) OR direct bilirubin ≤ ULN for subjects with total bilirubin levels \> 1.5 x ULN
2. Aspartate aminotransferase (AST) ≤ 2.5 × ULN or ≤ 5 × ULN for subjects with known hepatic metastases
3. Alanine aminotransferase (ALT) ≤ 2.5 × ULN or ≤ 5 × ULN for subjects with known hepatic metastases
13. Have adequate renal function as defined by the following criteria:
Creatinine ≤ 1.5 x ULN and CrCl ≥ 30 ml/min per Cockcroft Gault formula:
14. Have adequate hematologic function, defined as meeting all of the following criteria:
1. Hemoglobin ≥ 9 g/dL (uncorrected by RBC transfusion)
2. Absolute neutrophil count (ANC) ≥ 1.5 × 109/L
3. Platelet count ≥ 100 × 109/L
15. Have adequate coagulation functioning within 15 days prior to start of study treatment, defined by either of the following criteria:
1. INR \< 1.5 × ULN
2. OR for subjects receiving warfarin or low molecular weight heparin (LMWH), the subjects must, in the Investigator's opinion, be clinically stable with no evidence of active bleeding while receiving anticoagulant therapy. The INR for these subjects may exceed 1.5 × ULN if that is the goal of anticoagulant therapy.
3. Activated Partial Thromboplastin Time (aPTT) \< 1.5 × ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
16. Female subjects of childbearing potential as defined in Section 5.7.2 must have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
17. If of childbearing potential as defined in Section 5.7.2, must be willing to use an adequate method of contraception (see Section 5.7.2) from the first dose of study medication through 120 days after the last dose of study medication
18. Be willing and have the ability to comply with scheduled visits (including geographical proximity), treatment plans, laboratory tests, and other study procedures
