Study of Safety & Efficacy of the Combination of LJM716 & BYL719 in Patients With Previously Treated Esophageal Squamous Cell Carcinoma (ESCC)

A Phase Ib/II, Open-label Study of LJM716 in Combination With BYL719 Compared to Taxane or Irinotecan in Patients With Previously Treated Esophageal Squamous Cell Carcinoma (ESCC)

To study the safety and efficacy of the combination of LJM716 and BYL719 against currently available treatments of physician's choice in previously treated esophageal squamous cell carcinoma patients.

Study Overview

• Status: Completed
• Conditions: Esophageal Squamous Cell Carcinoma
• Intervention / Treatment: Drug: LJM716; Drug: BYL719; Drug: Paclitaxel; Drug: Docetaxel; Drug: Irinotecan

Detailed Description

The study design included a Phase 1b dose escalation portion to define the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) for the combination of LJM716 and alpelisib, followed by an open-label, randomized Phase 2 part to compare anti-tumor activity of LJM716-alpelisib combination versus physician's choice of second-line therapy (paclitaxel, docetaxel, irinotecan). However, the phase 2 part was not conducted as the study was terminated early due to limited anti-tumor activity with LJM716-alpelisib combination observed in phase 1b.

Description

Inclusion Criteria:

• Histologically confirmed esophageal squamous cell carcinoma (ESCC)
• No more than one prior chemotherapy regimen for recurrent or metastatic ESCC (for Phase II only).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: LJM716-BYL719 arm; approximately 42 previously treated esophageal squamous cell carcinoma (ESCC) patients will be enrolled to the LJM716-BYL719 combination arm to evaluate the anti-tumor activity and further assess the safety, tolerability and anti-tumor activity of the combination versus current therapies (physician's choice of paclitaxel, docetaxel or irinotecan).	Drug: LJM716; LJM716 (10-40 mg/kg) will be given as a once weekly infusion beginning on cycle 1 day 1. The doses of LJM716 will be increased as dose escalation proceeds until a maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) is established.; Drug: BYL719; BYL719 (200-400 mg) will be administered orally on a once daily schedule starting cycle 1 day 1. The doses of BYL719 will be increased as dose escalation proceeds until a maximum tolerated dose (MTD) and/or recommended phase II dose (RP2D) is established.
ACTIVE_COMPARATOR: Paclitaxel, Docetaxel or Irinotecan arm; approximately 42 previously treated esophageal squamous cell carcinoma (ESCC) patients will be enrolled to the Paclitaxel, Docetaxel or Irinotecan arm (physician's choice arm) to evaluate the anti-tumor activity and further assess the safety, tolerability and anti-tumor activity of the LJM716-BYL719 combination versus current therapies (physician's choice of paclitaxel, docetaxel or irinotecan).	Drug: Paclitaxel; In the Phase II portion of the study Paclitaxel is one of the 3 physician's choice drug which allows single-agent paclitaxel to be used per manufacturer's label.; Drug: Docetaxel; In the Phase II portion of the study Docetaxel is one of the 3 physician's choice drug which allows single-agent docetaxel to be used per manufacturer's label.; Drug: Irinotecan; In the Phase II portion of the study Irinotecan is one of the 3 physician's choice drug which allows single-agent irinotecan to be used per manufacturer's label

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Phase Ib primary outcome measure: Incidence rate of dose limiting toxicities (DLTs).	The open-label dose escalation part of the study will be guided by a well-established statistical method/model to estimate the maximum tolerated dose(s) and/or Recommended Phase II Dose (s) guided by the safety (incidence of dose limiting toxicities), efficacy, pharmacokinetics and pharmacodynamics data.	approximately 8 months
Phase II primary outcome measure: Progression free survival (PFS)	Progression-free survival is the time from date of start of treatment to the date of event defined as the first documented progression or death due to any cause. If a patient has not had an event, progression-free survival is censored at the date of last adequate assessment.
