Condition(s) targeted: Neoplasm Malignant

Intervention: SAR260301 (Drug); Vemurafenib (Drug)

Phase: Phase 1

Status: Completed

Official(s) and/or principal investigator(s):
Clinical Sciences & Operations, Study Director, Affiliation: Sanofi

Summary

Primary Objective:

Part A - Monotherapy:

- To determine the maximum tolerated dose (MTD) of SAR260301 administered as monotherapy and

either on a once or twice daily schedule, to patients with advanced solid tumors or lymphomas.

Part B - Combination:

- To determine the maximum tolerated dose (MTD) of SAR260301 administered in combination

with the recommended standard dosage of vemurafenib to patients with unresectable / metastatic v-raf murine sarcoma viral oncogene homolog B1 (BRAF)-mutated melanoma. Secondary Objectives:

- To characterize the overall safety and tolerability profile of SAR260301 administered

as monotherapy (Part A) and in combination with vemurafenib (Part B).

- To characterize the pharmacokinetic (PK) profile of SAR260301 administered as

monotherapy (Part A) and in combination with vemurafenib (Part B) as well as vemurafenib PK in combination with SAR260301 (Part B)

- To evaluate food effect on SAR260301 PK (Part A)

- To assess preliminary antitumor activity according to Response Evaluation Criteria in

Solid Tumors (RECIST 1. 1 criteria).

- To assess preliminary antitumor activity using volumetric computed tomography (CT) or

magnetic resonance imaging(MRI)

- To evaluate the pharmacodynamic (PD) effects of SAR260301 on blood and tumor.

- To evaluate PK/PD relationships.

- To identify the recommended phase 2 dose of SAR260301 in combination with vemurafenib

(RP2D) (Part B only)

- To assess potential induction effect of SAR260301 on cytochrome P450 (CYP) isoenzyme 3A

(CYP3A) (Part A)

Clinical Details

Official title: A Phase I/Ib Study for the Evaluation of SAR260301, Administered Orally in Monotherapy in Patients With Advanced Solid Tumors or Lymphomas, and in Combination With Vemurafenib in Patients With Unresectable / Metastatic BRAF-mutated Melanoma

Secondary outcome:

Number of patients with treatment emergent events

Assessment of PK parameters for SAR260301 and vemurafenib, including tmax, Cmax, AUC, Rac (Day 28/Day1), half-life, CL, Ctrough

Assessment of PK parameters for SAR260301 including tmax, Cmax, AUC fasting and fed (food effect)(Only part A)

Assessment of urine excretion of SAR2690301 (Part A)

Assessment of potential for CYP induction (4beta-hydroxycholesterol)(Part A)

Assessment of PK parameter Rac (Day 28/Day 1) on AUC and Cmax

Assessment of PD parameter Serine/threonine protein kinase Akt (AKT) phosphorylation in blood platelets

Assessment of PD parameter AKT phosphorylation in tumor (expansion phase only)

Assessment of preliminary antitumor activity as documented by tumor response (defined by RECIST1.1 criteria for solid tumors, international working group (IWG) and revised response for lymphomas, and tumor markers when relevant)

Detailed description: Study duration for one patient will include a period for inclusion (screening period) of up to 4 weeks, a treatment period of at least 4 weeks, and a end-of-study visit at 30 days following the last administration of study drug. The patient may continue treatment until disease progression, unacceptable toxicity or willingness to stop, followed by a minimum of 30-days follow-up.

Eligibility

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion criteria :

- Age ≥18 years old

- Locally advanced or metastatic solid tumor disease as well as lymphoma for which no

alternative therapy is available (Part A)

- Unresectable / metastatic BRAF-mutated melanomas, progressing on BRAF inhibitor after

no more than 4 months treatment or with only partial response (<50% change in tumor volume) after 4 months of treatment (Part B) or vemurafenib naive (Part B escalation phase only): anterior scans must be available for patients having received BRAF inhibitor prior to entry into the study.

- At least one measurable lesion by RECIST v1. 1

- Archived primary tumor biopsies or surgical specimens, or biopsies of recurrence or

metastasis, will be requested for all subjects for predictive markers of response analysis. Exclusion criteria:

- ECOG performance status >1

- Concurrent treatment with any other anticancer therapy

- Patient with reproductive potential (female and male) who do not agree to use an

accepted effective method of contraception during the study treatment period and for at least 6 months following completion of study treatment.

- Pregnancy or breast-feeding

- Any malignancy related to immunodeficiency virus (HIV) or solid organ transplant;

history of known HIV, unresolved viral hepatitis.

- Subjects with brain metastases of non-central nervous system (CNS) primary tumors are

excluded if their lesions are larger than 1 cm in the longest dimension, symptomatic or changed in size in the latest scan compared to the previous scan. Subjects must not require corticosteroid treatment or have received treatment for brain metastases for at least one month prior to study entry.

- Inadequate haematological function.

- Inadequate renal function.

- Inadequate liver function.

aggregation time >122 seconds using the collagen/ADP cartridge, and/or >183 seconds using the collagen/epinephrine cartridge.

- Current use of aspirin, clopidogrel, ticlopidine, prasugrel or ticagrelor.

ratio (INR) or activated partial thromboplastin time (aPTT) >1. 3X ULN. Prophylactic but not therapeutic anticoagulants are permitted.
