Dose Finding Study of TNO155 in Adult Patients With Advanced Solid Tumors

Phase 1
Active, not recruiting
Conditions

KRAS G12-mutant NSCLC
Esophageal Squamous Cell Cancer (SCC)
Head/Neck SCC
Melanoma
Advanced Gastrointestinal Stromal Tumors (GIST)
Advanced NRAS/BRAFT wt Cutaneous Melanoma
Interventions
Drug: TNO155 in combination with EGF816 (nazartinib)
Registration Number
NCT03114319
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

The purpose of this first in human (FIH) trial is to characterize the safety and tolerability of the SHP2 inhibitor TNO155 alone and in combination with EGF816 (nazartinib) and identify a recommended dose for future studies in adult patients with advanced solid tumors in selected indications.

Detailed Description

This study has been designed as a Phase I, open-label, dose finding study with a dose escalation part and a dose expansion part in adult patients with selected advanced solid tumors. The study treatment, TNO155 alone or in combination with EGF816 (nazartinib), will be taken until the patient experiences unacceptable toxicity, progressive disease and/or treatment is discontinued at the discretion of the investigator or the patient or due to withdrawal of consent.

Inclusion Criteria
  1. Able to understand and voluntarily sign the ICF and able to comply with the study visit schedule and the other protocol requirements.

  2. Patient (male or female) ≥18 years of age willing to agree to not father a child/become pregnant and comply with effective contraception criteria.

  3. Must have progressed following standard therapy, or for whom, in the opinion of the Investigator, no effective standard therapy exists, is tolerated or is appropriate.

  4. ECOG (Eastern cooperative oncology group) performance status ≤2

    Additional criteria only appying to TNO155 in combination with EGF816 (nazartinib):

  5. Patients must be screened for Hepatitis B virus and Hepatitis C virus

Exclusion Criteria
  1. Tumors harboring known activating KRAS, NRAS, HRAS, BRAF or PTPN11 (SHP2) mutations. (Exceptions are KRAS G12-mutant NSCLC's)

  2. History or current evidence of retinal vein occlusion (RVO) or current risk factors for RVO.

  3. Any medical condition that would, in the investigator's judgment, prevent the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures.

  4. Clinically significant cardiac disease.

  5. Active diarrhea or inflammatory bowel disease

  6. Insufficient bone marrow function

  7. Insufficient hepatic and renal function.

    Additional criteria only appying to TNO155 in combination with EGF816 (nazartinib):

  8. Patients with a known history of human immunodeficiency virus (HIV) seropositivity.

  9. Patients receiving concomitant immunosuppressive agents or chronic corticosteroids use at the time of study entry.

  10. Patients who have undergone a bone marrow or solid organ transplant

  11. Patients with a history or presence of interstitial lung disease or interstitial pneumonitis

  12. Bullous and exfoliative skin disorders at screening of any grade

  13. Presence of clinically significant ophthalmological abnormalities that might increase the risk of corneal epithelial injury

Primary Outcome Measures
NameTimeMethod
Number of participants with adverse events and serious adverse eventsup to 5 years; at least once per treatment cycle

All patients participating in this study will be assessed for incidence and severity of adverse events (AEs) and serious AEs, including changes in laboratory values, vital signs, electrocardiograms and cardiac biomarkers

Number of participants with dose limiting toxicitiesup to 28-day cycle

Incidence and nature of dose limiting toxicities (DLTs) in the dose escalation part. A DLT is defined as an adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurs within the first treatment cycle (either 21 days or 28 days, depending on the cohort's treatment schedule) with TNO155 or with TNO155 in combination with EGF816 (nazartinib)

Number of participants with dose interruptions and reductionsUp to 5 years

Assessment of tolerability. For patients who do not tolerate the protocol-specified dosing schedule, dose adjustments may be permitted in order to allow patients to continue the study treatment

Dose intensity of study drugsUp to 5 years

Dose intensity is computed as the ratio of actual cumulative dose received to actual duration of exposure

Secondary Outcome Measures
NameTimeMethod
Change from baseline in DUSP6 in tumor samplesAt screening and between Cycle 1 and Cycle 3. One cycle=either 21 days or 28 days, depending on the cohort's treatment schedule.

Dual Specificity Phosphatase 6 (DUSP6) mRNA levels assessed in paired tumor biopsy samples by quantitative polymerase chain reaction (qPCR)

Area under the plasma concentration-time curve (AUC) of study drugsFrom pre-dose up to 48 hours post-dose on Cycle 1 Day 1 and from pre-dose up to 24 hours post-dose on Cycle 1 Day 14. One cycle=21 days or 28 days, depending on the dosing schedule.

Pharmacokinetic (PK) parameters calculated based on the plasma concentrations versus time profiles by using non-compartmental methods

Overall response rate (ORR) per RECIST v1.1From start of treatment for 60 months

ORR is the proportion of patients with a best overall response of Complete Response (CR) or Partial response (PR)

Disease control rate (DCR) per RECIST v1.1From start of treatment for 60 months

DCR is the proportion of patients with a best overall response of CR or PR or stable disease (SD)

Progression-free survival (PFS) per RECIST v1.1Up to 5 years

PFS is the time from date start of treatment to the date of event defined as the first documented progression or death due to any cause

Duration of response (DOR) per RECIST v1.1Up to 5 years

DOR is the time from first documented response (PR or CR) to the date of first documented disease progression or death due to any cause

Peak plasma concentration (Cmax) of study drugsFrom pre-dose up to 48 hours post-dose on Cycle 1 Day 1 and from pre-dose up to 24 hours post-dose on Cycle 1 Day 14. One cycle=21 days or 28 days, depending on the dosing schedule.

PK parameters calculated based on the plasma concentrations versus time profiles by using non-compartmental methods

Time to reach peak plasma concentration (Tmax) of study drugsFrom pre-dose up to 48 hours post-dose on Cycle 1 Day 1 and from pre-dose up to 24 hours post-dose on Cycle 1 Day 14. One cycle=21 days or 28 days, depending on the dosing schedule.

PK parameters calculated based on the plasma concentrations versus time profiles by using non-compartmental methods

Apparent terminal elimination half-life of study drugsFrom pre-dose up to 48 hours post-dose on Cycle 1 Day 1 and from pre-dose up to 24 hours post-dose on Cycle 1 Day 14. One cycle=21 days or 28 days, depending on the dosing schedule.
