Study of Intravenous RXDX-107 in Patients With Solid Tumors

NCT02548390 | Terminated Phase 1

• 1 other identifier: RXDX-107-01
• Study Type: interventional
• Target: 70
• Locations: 1 country
• Sites: 3

Brief Summary

This is an open-label, Phase I/Ib, dose escalation study of intravenous RXDX-107 administered to subjects with advanced solid tumors. The study is designed to explore the safety, maximum tolerated dose (MTD), pharmacokinetics, pharmacodynamics, and preliminary clinical activity of RXDX-107 and to define a recommended Phase 2 dose (RP2D)

Outcome Measures

Primary Outcomes (9)

• Phase 1: Safety profile of RXDX-107 as characterized by Adverse Events, ECG and laboratory abnormalities

  AEs, ECG and Labs assessed according to NCI CTCAE V4.0

  Approx. 1 year

• Phase 1: Maximum observed plasma drug concentration (Cmax)

  Plasma concentrations obtained following the dose on Day 1 (and from the dose on Day 2 in patients receiving the Day 1 and Day 2 schedule)

  Approx. 1 year

• Phase 1: Time to Cmax, by inspection (tmax)

  Plasma concentrations obtained following the dose on Day 1 (and from the dose on Day 2 in patients receiving the Day 1 and Day 2 schedule)

  Approx. 1 year

• Phase 1: Area under the drug concentration by time curve (AUC)

  From time 0 to the time of the last detectable plasma concentration (AUC0-t)

  Approx. 1 year

• Phase 1: Apparent plasma terminal elimination rate constant (λz) and associated terminal half life (t½)

  Plasma concentrations obtained following the dose on Day 1 (and from the dose on Day 2 in patients receiving the Day 1 and Day 2 schedule)

  Approx. 1 year

• Phase 1: Plasma clearance (CL)

  Plasma concentrations obtained following the dose on Day 1 (and from the dose on Day 2 in patients receiving the Day 1 and Day 2 schedule)

  Approx. 1 year

• Phase 1: Volume of distribution (Vz)

  Plasma concentrations obtained following the dose on Day 1 (and from the dose on Day 2 in patients receiving the Day 1 and Day 2 schedule)

  Approx. 1 year

• Phase 1: Maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D)

  Approx. 6 months

• Phase 1b: Confirm RP2D

  Number of participants with Treatment-related AEs, Labs changes from baseline, and QTc interval changes from baseline assessed according to NCI CTCAE V4.0, concomitant medication usage, including all supportive care provided, and preliminary anti-tumor activity per RECIST v1.1 as assessed by Investigator

  Approx. 1 year

Secondary Outcomes (1)

• Antitumor activity of RXDX-107 as measured by Objective Response Rate (ORR)

  Approx. 1 year

RXDX-107

EXPERIMENTAL

Drug: RXDX-107

Interventions

RXDX-107 DRUG

Subjects in this study will receive RXDX-107 intravenously at dose levels specified for their respective dose cohorts. Dosing will begin at 25 mg/m2 on Day 1 and Day 2 of a 28-day cycle and will escalate until the maximum tolerated dose (MTD) or (RP2D) is determined. An additional schedule of administration of RXDX-107 on Day 1 of a 28 day cycle may be assessed. Cycles will be repeated in four-week (28 day) intervals for up to 6 cycles or until progression of disease, unacceptable toxicity, or another discontinuation criterion is met.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Confirmed relapsed or refractory locally advanced or metastatic solid cancer for whom no standard therapy is considered appropriate, or for whom standard therapy is considered intolerable.
• \>18 years of age.
• ECOG performance status of 0 or 1.
• Life expectancy of at least 3 months.
• Received the last dose of previous treatment / therapy before Day 1 of cycle 1:
• days for cytotoxic chemotherapy, immunotherapy, whole brain radiotherapy, anticonvulsive therapy, stereotactic radiosurgery and major surgery
• days for nitrosureas, mitomycin C, and liposomal anthracycline
• days for non-cytotoxic cancer therapies and radiotherapy
• Recovered from all toxic effects (excluding alopecia) of any prior anti-cancer therapy to Grade ≤ 1 or to the baseline laboratory values.
• Adequate organ function and baseline laboratory values
• Women of childbearing potential must have a negative serum pregnancy
• Phase 1b: Patient must have measurable disease

You may not qualify if:

• Receiving other experimental therapy
• Known symptomatic brain mets or leptomeningeal involvement
• Myocardial infarction in the previous 12 weeks. Active ischemia or any other uncontrolled cardiac condition such as angina pectoris, significant cardiac arrhythmia requiring therapy, uncontrolled hypertension, or CHF.
• Another concurrent illness which would preclude study conduct and assessment, uncontrolled: medical condition, active infection, risk of bleeding, diabetes mellitus, or pulmonary disease, or alcoholic liver disease, or primary biliary cirrhosis.
• Malignancy within 3 years or active disease requiring treatment other than the target cancer. The exceptions are prostate cancer (Gleason grade \< 6 with normalized PSA levels), treated in situ cervical, breast carcinoma, squamous or basal cell skin cancer.
• Any condition that may compromise the ability to give written informed consent or to comply with the study protocol.
