Brief Summary:
This is a Phase 1b/2 study of AVB-S6-500 designed to evaluate the safety and efficacy of AVB-S6-500 in combination with cabozantinib in subjects with advanced clear cell renal cell carcinoma (ccRCC) that have received front-line treatment. The phase 1b portion of the study is open label and patients will receive AVB-S6-500+Cabozantinib in 3+3 dose escalation. The Phase 2 portion of the study is randomized, 2-arm, open-label study to compare efficacy and tolerability of AVB-S6-500+cabozantinib versus cabozantinib alone

Condition or disease Intervention/treatment Phase
Clear Cell Renal Cell Carcinoma Drug: AVB-S6-500 Drug: Cabozantinib (Cabo) Phase 1 Phase 2

Arm Intervention/treatment
Experimental: Phase 1b: AVB-S6-500+Cabo Drug: AVB-S6-500
AVB-S6-500 is experimental drug

Drug: Cabozantinib (Cabo)
Cabo is active comparator
Other Name: Cabometyx®

Experimental: Phase 2: AVB-S6-500+Cabo Drug: AVB-S6-500
AVB-S6-500 is experimental drug

Drug: Cabozantinib (Cabo)
Cabo is active comparator
Other Name: Cabometyx®

Experimental: Phase 2: Cabo alone Drug: Cabozantinib (Cabo)
Cabo is active comparator
Other Name: Cabometyx®

Primary Outcome Measures :
  1. Identify the recommended Phase 2 dose of AVB-S6-500 in combination with cabozantinib [ Time Frame: 10 months ]
    Measured by dose limiting toxicities experienced in Phase 1b

  2. Anti-tumor activity of AVB-S6-500 in combination with Cabozantinib [ Time Frame: 30 months ]
    Measured by progression free survival (PFS) in patients receiving AVB-S6-500+Cabo versus patients receiving Cabo alone in Phase 2

Secondary Outcome Measures :
  1. Pharmacokinetics: AUC [ Time Frame: 30 months ]
    Area under the AVB-S6-500 concentration-time curve.

  2. Pharmacokinetics: Cmax [ Time Frame: 30 months ]
    Maximum observed AVB-S6-500 concentration.

  3. Pharmacokinetics: Tmax [ Time Frame: 30 months ]
    Time of maximum observed AVB-S6-500 concentration.

  4. Pharmacokinetics: t1/2 [ Time Frame: 30 months ]
    Apparent terminal half-life of AVB-S6-500.

  5. Pharmacodynamic marker assessment [ Time Frame: 30 months ]
    Change from the baseline in GAS6 serum levels.

  6. Anti-drug antibody (ADA) titers [ Time Frame: 30 months ]
    Change from baseline in ADA titer.

  7. Objective response rate [ Time Frame: 30 months ]
    Proportion of subjects who have a partial or complete confirmed response to therapy relative to baseline as assessed per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1.

  8. Clinical benefit rate [ Time Frame: 30 months ]
    Proportion of subjects who have a complete or partial response to therapy or maintain stable disease.

  9. Duration of response (DOR) [ Time Frame: 30 months ]
    Measured from the date of partial or complete response to therapy until the cancer progresses.

  10. Overall survival [ Time Frame: 60 months ]
    Time following the treatment until death.
