STELLAR-002: This study is assessing how effective, safe and tolerable a new drug (called XL092) is in combination with immunotherapy drugs in people with solid tumoursA Dose-Escalation and Expansion Study of the Safety and Efficacy of XL092 in Combination With Immuno-Oncology Agents in Subjects With Unresectable Advanced or Metastatic Solid Tumors

Inclusion

• Cytologically or histologically confirmed solid tumor that is unresectable, locally advanced or metastatic.
• Dose-Escalation Cohorts: Subjects with a solid tumor that is unresectable or metastatic and for which life-prolonging therapies do not exist or available therapies are intolerable or no longer effective.

• Expansion Cohort 1 (ccRCC): Subjects with unresectable advanced or metastatic RCC with a clear cell component who have not received prior systemic therapy.

  • Note: Prior non-VEGF targeted adjuvant or neoadjuvant is allowed if disease recurrence occurred 6 months after the last dose.

• Expansion Cohort 2 (ccRCC): Subjects with unresectable advanced or metastatic RCC with a clear cell component.

  • Must have radiographically progressed after a combination therapy consisting of a PD-1/PD-L1 targeting mAb with a VEGFR-TKI or a PD-1 targeting mAb with a CTLA-4 mAb as the preceding line of therapy.
  • Must have received no more than one prior systemic anticancer therapy for unresectable advanced or metastatic renal cell carcinoma.

• Expansion Cohort 3 (mCRPC): Men with metastatic adenocarcinoma of the prostate.

  • Must have progressed during or after one NHT given for castration-sensitive locally advanced (T3 or T4) or metastatic castration-sensitive prostate cancer (CSPC), M0 CRPC, or mCRPC.

• Expansion Cohort 4 (UC, ICI-naive): Subjects with histologically confirmed unresectable, locally advanced or metastatic transitional cell carcinoma of the urothelium (including the renal pelvis, ureter, urinary bladder, or urethra).

  • Must have progressed during or after prior first-line platinum-based combination therapy, including subjects who received prior neoadjuvant or adjuvant platinum-containing therapy with disease recurrence < 12 months from the end of last therapy.
  • Must have received no more than 1 prior line of systemic anticancer therapy for unresectable, locally advanced or metastatic disease.

• Expansion Cohort 5 (UC, ICI-experienced): Subjects with histologically confirmed unresectable, locally advanced or metastatic transitional cell carcinoma of the urothelium (including the renal pelvis, ureter, urinary bladder, or urethra).

  • Must have progressed during or after prior PD-1/PD-L1 targeting ICI therapy given as monotherapy, combination therapy, maintenance therapy or adjuvant therapy.
  • Must have received no more than 2 prior lines of systemic anticancer therapy for unresectable advanced or metastatic disease.

• Expansion Cohort 6 (nccRCC): Subjects with unresectable advanced or metastatic nccRCC of the following subtypes: Papillary RCC (any type), unclassified RCC, and translocation-associated. Among the eligible histologic subtypes, sarcomatoid features are allowed.

  • No prior systemic anticancer therapy is allowed except adjuvant or neoadjuvant therapy if disease recurrence occurred at least 6 months after the last dose.
• Expansion Cohort 7 (HCC): Subjects with inoperable locally advanced, recurrent, or metastatic HCC that is not amenable to curative treatment or locoregional therapy.
• Expansion Cohort 8 (NSCLC): Subjects with Stage IV non-squamous NSCLC with positive PD-L1 expression (tumor proportion score [TPS] 1-49%) and without prior systemic anticancer therapy for metastatic disease.
• Expansion Cohort 9 (NSCLC): Subjects with Stage IV non-squamous NSCLC who have radiologically progressed following treatment with one prior immune checkpoint inhibitor (anti-PD-1 or anti-PD-L1) for metastatic disease.
• Expansion Cohort 10 (CRC): Subjects with histologically confirmed unresectable, locally advanced, or metastatic adenocarcinoma of the colon or rectum.
• Expansion Cohort 11 (HNSCC): Subject with inoperable, refractory, recurrent or metastatic HNSCC of the oral cavity, oropharynx, hypopharynx, and larynx. PD-L1 combined positive score (CPS) ≥1.
• For all Expansion Cohorts except Cohort 3: Measurable disease per RECIST 1.1 as determined by the Investigator.
• For expansion cohorts only: Archival tumor tissue material, if available, or fresh tumor tissue if it can be safely obtained.
• Recovery to baseline or ≤ Grade 1 CTCAE v5 from AE(s) related to any prior treatments unless AE(s) are deemed clinically nonsignificant by the Investigator and/or stable on supportive therapy.
• Karnofsky Performance Status (KPS) ≥ 70%.
• Adequate organ and marrow function.
• Sexually active fertile subjects and their partners must agree to use highly effective methods of contraception.
• Female subjects of childbearing potential must not be pregnant at screening.
