DES: Maximum tolerated dose or recommended Phase 2 dose
Up to 36 weeks, from the date of first dose until unacceptable side effects or a dose-limiting toxicity is met

Evaluate adverse events and concomitant medication use after XMT-1536 (upifitamab rilsodotin) doses

DES and EXP: Safety and Tolerability
First dose up until 30 days after study termination

Evaluate incidence and severity of adverse events

EXP: Anti-neoplastic effects of XMT-1536 (upifitamab rilsodotin)
Every 6 weeks for up to 36 weeks

Monitor tumor size

UPLIFT: Investigator-assessed objective response rate (ORR) of XMT-1536 (upifitamab rilsodotin) in the ITT-Higher NaPi2b population
Every 8 weeks until disease progression or up to 24 months

Confirmed ORR is defined as the proportion of patients who have achieved a confirmed complete response (CR) or partial response (PR) per RECIST v1.1 after the initiation of study treatment.

QTc Sub-study: Evaluation of the concentration response analysis of XMT-1536 versus the change in QTcF values
60 minutes prior to first dose, up to 26 hours after Cycle 3 dose

"The concentration-QTcf change from baseline deltaQTcF analysis and analysis of central tendency for deltaQTcF

Secondary Endpoints

DES and EXP: Maximum concentration of XMT-1536 (upifitamab rilsodotin)
Daily for one week after first dose; weekly until 28 days after first dose; immediately before and after and 1 week after all subsequent doses
DES and EXP: Area under the concentration curve of the last measurable concentration of XMT-1536 (upifitamab rilsodotin)
Daily for one week after first dose; weekly until 28 days after first dose; immediately before and after and 1 week after all subsequent doses

ArmTypeDescription
Dose Expansion - Ovarian CancerEXPERIMENTALOnce the maximum tolerated dose or recommended Phase 2 dose is achieved in dose escalation, new groups of patients will receive XMT-1536 (upifitamab rilsodotin) at this fixed-dose. This cohort is closed to enrollment.
Dose Expansion - NSCLC adenocarcinomaEXPERIMENTALOnce the maximum tolerated dose or recommended Phase 2 dose is achieved in dose escalation, new groups of patients will receive XMT-1536 (upifitamab rilsodotin) at this fixed-dose. This cohort is closed to enrollment.
Dose EscalationEXPERIMENTALXMT-1536 (upifitamab rilsodotin) treatment is administered in groups of patients who will receive doses that increase over time. This cohort is closed to enrollment.
Pivotal Cohort (UPLIFT)EXPERIMENTALPatients with platinum-resistant ovarian cancer will receive XMT-1536 (upifitamab rilsodotin) to further confirm the efficacy. This cohort is closed to enrollment.
QTc Sub-StudyEXPERIMENTALFor sites participating in the sub-study, patients with platinum -resistant ovarian cancer will have the option to enroll in this sub-study to evaluate potential changes in the QTc interval following administration of XMT-1536. This cohort is closed to enrollment.
Interventions
NameTypeDescription
upifitamab rilsodotinDRUGXMT-1536 will be administered once every 28 days until disease progression, unacceptable toxicity, or either the patient or study physician determines it is in the best interest of the patient to discontinue participation in the study. For sites participating in the sub-study, patients with platinum -resistant ovarian cancer will have the option to enroll in this sub-study to evaluate potential changes in the QTc interval following administration of XMT-1536
