• Have undergone treatment with ASCT or have progressed from at least 2 other prior treatment lines (including an immunomodulatory imide drug and/or daratumumab);
• Have relapsed on, or been refractory or intolerant to, the last treatment line, and have measurable disease evaluated by monoclonal proteins (M-proteins) and/or free light chains according to IMWG response criteria (Appendix C). Non-secretory MM must have measurable, active lesions by positron emission tomography;

• Female patients of childbearing potential must have a negative serum pregnancy test at screening and a negative (urine or serum) pregnancy test within 72 hours prior to receiving the first dose of study drug. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required and must be negative for the patient to be eligible;
• Female patients who are not postmenopausal, and who have not undergone surgical sterilization, must agree to use highly effective methods of contraception during the treatment period and for 6 months after the last dose of study drug. They must also agree not to donate eggs (ova, oocytes) during the same timeframe; and
• Male patients with partners of childbearing potential must agree to use highly effective methods of contraception and barrier contraception (condom) during the treatment period and for 6 months after the last dose of study drug. They must also agree not to donate sperm during the same timeframe.

Exclusion criteria

• Have received an investigational agent (including investigational device) <4 weeks or 5 half-lives prior to study Cycle 1 Day 1, whichever is longer;

• Have hypersensitivity to any components of ANV419 (IL-2, anti-IL-2 mAb) or its formulation (L-histidine, L-histidine HCl, sucrose, polysorbate 80, water; see Appendix D);

• Have hypersensitivity to lenalidomide, dexamethasone, daratumumab, or any of their excipients;

• Have received daratumumab <3 months prior to the signing of informed consent;

• Have received any drugs that may be active for MM <3 weeks prior to the signing of informed consent;

• Have received high-dose corticosteroids (≥1 mg/kg) ≤3 weeks prior to the signing of informed consent;

• Have received radiotherapy ≤1 month prior to the signing of informed consent;

• Have had an autologous hematopoietic cell transplant (HCT) within the last 6 months;

• Have had a previous allogeneic HCT;

• Have had major surgery <4 weeks prior to the signing of informed consent or anticipate the need for major surgery during treatment; Note: Major surgery is defined as any surgery requiring entrance into a body cavity (eg, chest, abdomen, or brain), organ removal, normal anatomy alteration, or joint replacement. Minor surgery is defined as any surgery in which skin, mucosa, or connective tissue sections are altered (eg, biopsy, cataract, endoscopic procedures, etc).

• Have clinical signs of meningeal involvement of MM;

• Have a history of a past or current malignancy prior to screening, except for:

  1. Cervical carcinoma of Stage 1B or less;
  2. Non-invasive basal cell or squamous cell skin carcinoma requiring treatment; or
  3. Current or past malignancy with a complete response for <3 years at screening.

• Have plasma cell leukemia defined as a plasma cell count >2000/mm3;

• Have known amyloidosis;

• Have sensory and/or motor neuropathy ≥Grade 3 per NCI CTCAE version 5.0 at screening;

• Have active (measurable) and/or uncontrolled (unresponsive to current therapy) infectious disease (bacterial, fungal, viral, or protozoic);

• Have evidence of uncontrolled (unresponsive to current therapy), concomitant disease including, but not limited to, uncontrolled diabetes mellitus (pre-existing diabetes mellitus type 1 is acceptable), chronic obstructive pulmonary diseases Grade 3 (per NCI CTCAE version 5.0) or higher, asthma, bronchospasm, obstructive pulmonary disease, hematological diseases except MM, renal impairment (except when related to MM), hyperthyroidism due to thyroiditis, known autoimmune disease, or disease with ongoing fibrosis;

• Have clinically significant (defined as a disease that requires intervention) cardiovascular disease including, but not limited to, acute myocardial infarction and/or transient ischemic attack <6 months prior to screening, unstable angina, congestive heart failure (New York Heart Association Class II or higher), or arrhythmia requiring therapy;

• Have an average QTcF interval >480 msec at screening;

• Have active, untreated, immune-related endocrinopathy untreatable with hormone replacement or prior immune-related toxicities (eg, colitis, neuropathy) >Grade 3 (per NCI CTCAE version 5.0) after treatment with immunostimulatory drugs that have not been resolved;

• Have evidence of severe hepatic impairment (equivalent to Child-Pugh Class C [for liver cirrhosis] or a MELD [Model for End-Stage Liver Disease] score of 10 or higher for hepatic impairment not limited to cirrhosis]);

• Have a history or current evidence of any condition, therapy, or laboratory abnormality that might significantly confound the results of the study, interfere with the patient's participation for the full duration of the study, or it is not in the best interest of the patient to participate in the study, in the opinion of the treating Investigator;

• Have a known psychiatric or substance abuse disorder that would interfere with cooperation with the requirements of the study;

• Are pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the study, from screening through 6 months after the last dose of study drug;

  1. CD4+ lymphocyte count >350 µL;
  2. Had no history of AIDS (acquired immunodeficiency syndrome)-defining opportunistic infections within the past 12 months;
  3. Have been on established anti-retroviral therapy for at least 4 weeks; and
  4. Have an HIV viral load of <400 copies/mL prior to study Day 1. Note: Patients on strong cytochrome P450 (CYP)3A4 inhibitors or strong CYP3A4 inducers must be switched to an alternate effective anti-retroviral therapy regimen prior to study treatment or are excluded if regimen prior to study Day 1 cannot be altered.

• Have uncontrolled hepatitis B infection or hepatitis C infection; Note: Patients with hepatitis B (positive hepatitis B surface antigen) who have controlled infection (serum hepatitis B virus DNA by PCR that is below the limit of detection and receiving anti-viral therapy for hepatitis B) are permitted. Patients with controlled infections must undergo periodic monitoring of hepatitis B virus DNA. Note: Patients with hepatitis C (positive hepatitis C virus antibody) who have controlled infection (undetectable hepatitis C virus RNA by PCR either spontaneously or in response to a successful prior course of anti-hepatitis C virus therapy) are permitted.

• Have received a live vaccine within 30 days of study Day 1. Note: Seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however, intranasal influenza vaccines (eg, Flu-Mist®) are live attenuated vaccines, and are not allowed
