NCT04665206

Brief Summary

This is an open-label, dose escalation and expansion study to evaluate the safety, tolerability, PK, and biological activity of VT3989 administered, alone or in combination, once daily in patients with mesothelioma and/or metastatic solid tumors that are resistant to standard therapy or for which no effective standard therapy is available.

Study Arms (3)

VT3989 Dose Escalation [Not Recruiting]

EXPERIMENTAL

VT3989 dosed orally in 21 or 28 day cycles. Patients will be enrolled into escalating dose levels during the Dose Escalation Phase

Drug: VT3989

Dose Expansion [Not Recruiting]

EXPERIMENTAL

VT3989 dosed in 21 or 28 day cycles in patients with refractory metastatic solid tumors or mesothelioma.

Drug: VT3989

Combination [Recruiting]

EXPERIMENTAL

For Cohort A and B, VT3989 dosed in 28 day cycles in patients with metastatic solid tumors or mesothelioma, in combination with immunotherapy (nivolumab/ipilimumab) or targeted therapy (osimertinib). For Cohort C, VT3989 dosed in 21 day cycles in patients with mesothelioma in combination with chemotherapy (pemetrexed+carboplatin) for 4-6 cycles, then continuing VT3989 as monotherapy on 28-day cycle.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Part 3 Combination Cohort A: Patients with pathologically diagnosed, metastatic or unresectable malignant mesothelioma (including both pleural and non-pleural) who have not received systemic therapy.
  • Part 3 Combination Cohort B: Patients with pathologically diagnosed incurable locally advanced (inoperable or recurrent), or metastatic NSCLC with exon 19 deletions or exon 21 L858R mutations, with or without prior treatment with Osimertinib.
  • Part 3 Combination Cohort C: Patients with pathologically diagnosed metastatic or unresectable malignant pleural mesothelioma who have not received systemic chemotherapy.
  • Measurable disease per RECIST v1.1 for non-pleural mesothelioma or other solid tumors or modified RECIST v1.1 for malignant pleural mesothelioma. mRECIST may be used for pleural extension of non-pleural mesothelioma or for mixed pleural and peritoneal (or other) mesothelioma.
  • ECOG: 0-1.
  • Adequate organ functions, including the liver, kidneys, and hematopoietic system.

You may not qualify if:

  • Active brain metastases or primary CNS (central nervous system) tumors.
  • History of leptomeningeal metastases
  • Active or chronic, uncontrolled bacterial, viral, or fungal infection(s) requiring systemic therapy
  • Known HIV positive or active Hepatitis B or Hepatitis C
  • Clinically significant cardiovascular disease and prior exposure to cardiotoxic agents.
  • Corrected QT (QTcF) interval \> 470 msec (using Fridericia's correction formula).
  • Additional active malignancy that may confound the assessment of the study endpoints
  • Women who are pregnant or breastfeeding
  • Prior treatment with TEAD inhibitor.
