Brief Summary:
This is a phase 1/2 single arm study to determine the safety and efficacy of VLX1570 IV infusion administered with low dose dexamethasone in patients with relapsed or relapsed and refractory multiple myeloma.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: VLX1570 and dexamethasone Phase 1 Phase 2

Detailed Description:

This is a phase 1/2, open label study to determine the safety and efficacy of VLX1570 intravenous (IV) infusion administered with low dose dexamethasone on days 1, 2, 8, 9, 15, 16 of a 28-day cycle in patients with confirmed diagnosis of multiple myeloma with relapsed or relapsed and refractory disease (RRMM).

The phase 1 trial design follows an Initial Accelerated Titration design followed by a traditional "3+3" cohort design to establish maximum tolerated dose (MTD) and recommended phase 2 dose (RPTD) for the phase 2 portion of the study. It is anticipated that patients will receive 6 treatment cycles. In the absence of unacceptable toxicity and disease progression, patients have the option of continuing treatment beyond 6 cycles, if the investigator determines that the patient may benefit further from it.

Dexamethasone 20 mg PO/IV

Drug: VLX1570 and dexamethasone

Primary Outcome Measures :
  1. Maximum tolerated dose (MTD) of VLX1570 with low dose dexamethasone [ Time Frame: Duration of treatment (expected avg. 6 months) and up to 30 days following the last dose/off-study ]
  2. Clinical benefit rate (minimal response or better) in patients associated with administration of VLX1570 with low dose dexamethasone [ Time Frame: From date of first dose until the date of first documented progression or date of death from any cause, whichever comes first, up to 2 years ]

Secondary Outcome Measures :
  1. Frequency and severity of adverse events associated with the combination of VLX1570 and low dose dexamethasone [ Time Frame: Duration of treatment (expected avg. 6 months) and up to 30 days following the last dose/off-study ]
  2. Pharmacokinetic profile of VLX1570 following IV infusion [ Time Frame: 48 hours post dose ]
    PK parameters include Cmax, Tmax, AUC, half-life, clearance

  3. Investigate Objective Response per International Myeloma Working Group criteria at any dose of VLX1570 with low dose dexamethasone. [ Time Frame: Pre-dose cycle 1, 2 and cycles on new dose, and in cycle 5 (or at time of CR or PD). ]

Other Outcome Measures:
  1. Blood, bone marrow and other tissues collected during study, will be used for biomarker and mechanism of action studies [ Time Frame: Pre-dose each day 16 of each new cycle on new dose and in cycle 5 (or at time of CR or PD) ]
    May include examination of gene expression, proteomics and functional analysis or proteasomes, proteasomal subunits and associated enzymes

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Diagnosis of relapsed or relapsed and refractory multiple myeloma following at least 2 prior therapies which must include at least one immunomodulatory drug (e.g., thalidomide, lenalidomide or pomalidomide) and one proteasome inhibitor (e.g., bortezomib or carfilzomib). Patients must not be candidates for regimens known to provide clinical benefit.
  2. Measurable disease defined by 1 or more of the following:

    • Serum monoclonal protein ≥ 0.5 g/dL
    • Urine monoclonal protein >200 mg/24 hour
    • Serum immunoglobulin free light chain >10 mg/dL AND abnormal kappa/lambda ratio (reference 0.26-1.65)
  3. Estimated glomerular filtration rate (GFR) ≥30 mL/min as assessed by CKD-epi, MDRD or the Cockcroft-Gault Equation
  4. Age ≥18 years.
  5. Eastern Cooperative Oncology Group (ECOG) performance status 0, 1 or 2.
  6. Females of child-bearing potential* must have a negative pregnancy test.
  7. Males and females of child-bearing potential*, willing to use an effective form of contraception during chemotherapy treatment and for at least 6 months thereafter. Such methods include: (if using hormonal contraception this method must be supplemented with a barrier method, preferably male condom)

    • oral, intra-vaginal or transdermal combined (estrogen and progestogen containing) hormonal contraception associated with inhibition for ovulation
    • oral, injectable or implantable progestogen-only hormonal contraception associated with inhibition of ovulation.
    • intrauterine device (IUD)
    • intrauterine hormone-releasing system (IUS)
    • bilateral tubal occlusion
    • vasectomised partner
    • true sexual abstinence when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods), declaration of abstinence for the duration of the trial, and withdrawal are not acceptable methods of contraception.

  10. Uncontrolled intercurrent illness including but not limited to psychiatric illness/social situations that, in the opinion of the Investigator, would compromise compliance of study requirements or put the patient at unacceptable risk.
  11. Active infection requiring systemic treatment within one week prior to first dose.
