  • Brain metastases that are: untreated, progressive, have required any type of major treatment, e.g., whole-brain radiation treatment, adjuvant chemotherapy, gamma knife, to control symptoms from brain metastases within 30 days of the first study treatment. Or any history of leptomeningeal metastasis.
  • Current known active infection with HIV, hepatitis B virus, or hepatitis C virus.
  • No prior history of liver disease such as liver cirrhosis, hepatic fibrosis
  • Current severe, uncontrolled systemic disease (e.g., clinically significant cardiovascular, pulmonary, or metabolic disease) or intercurrent illness that could interfere with per-protocol evaluations.
  • Severe dyspnea at rest due to complications of advanced malignancy, or requiring supplementary oxygen therapy.
  • Currently active pneumonitis or interstitial lung disease.
  • Pregnant or nursing women.
  • History of other malignancy within the last 5 years, except for appropriately treated carcinoma in situ of the cervix, non-melanoma skin carcinoma, or other malignancy with a similar expected curative outcome.
  • Participation in the DES component of the study.

5. Study Description

Brief Summary
Phase 1b, a study in high grade serous ovarian cancer and nonsmall cell lung cancer to evaluate the safety and clinical activity of the antibody-drug conjugate (ADC) XMT-1592.
Detailed Description
This Phase 1b trial is an open-label, multi-center study of XMT-1592 administered as an intravenous infusion once every 3 weeks. The dose-escalation (DES) segment of the study will establish the expansion (EXP) dose and is intended to establish the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) for XMT-1592 in patients with high grade serous ovarian cancer (HGSOC) or non-small cell lung cancer (NSCLC), adenocarcinoma subtype. The EXP segment of the study will consist of 2 parallel cohorts of patients (HGSOC and NSCLC) to confirm the MTD or RP2D and estimate the objective response rate in each selected patient population. In DES, the observation period for dose-limiting toxicities is 21 days, between Day 1 through the end of Cycle 1 which includes the pre-dose assessments before receiving the Cycle 2 dose. All adverse events (AEs) will be graded according to NCI, CTCAE v5.0). In general, AEs ≥Grade 3 are dose-limiting toxicities with some modifications.
