"The majority of NSCLC patients either do not respond to checkpoint inhibitor therapy or experience disease progression following treatment. These patients have limited treatment options and generally experience poor outcomes in response to standard of care chemotherapy," said Charles M. Baum, M.D., Ph.D., President and Chief Executive Officer. "The preliminary data from our Phase 2 study of sitravatinib plus nivolumab continue to highlight the promise of this combination to overcome resistance to initial checkpoint inhibitor therapy and provide a meaningful treatment option for this large and underserved patient population."

Sitravatinib is being evaluated in a Phase 2 study in combination with nivolumab (OPDVIO), an anti-PD-1 checkpoint inhibitor, in patients with NSCLC who have experienced documented disease progression following prior treatment with a checkpoint inhibitor. As of the data cutoff date of March 31, 2018:

23 patients were evaluable for response with at least one radiographic scan

Six patients achieved a Partial Response (PR) (four confirmed and two unconfirmed)

1Five of the six patients with PRs remain on study, including both patients with unconfirmed PRs; the longest treatment duration exceeds 50 weeks and is ongoing

The other patient with a PR progressed following a treatment duration that exceeded 40 weeks

19 of 23 patients demonstrated tumor reductions

To date, the combination has been well-tolerated and most adverse events (AEs) reported by investigators were Grade 1 or 2.
"The responses and duration of treatment seen with the combination of sitravatinib and a checkpoint inhibitor are very promising, notably because these patients had relapsed following prior checkpoint inhibitor therapy," said Alexander Spira, M.D., Ph.D., Director of the Virginia Cancer Specialists Research Institute. "The trial is enrolling well, and we have been pleased with the favorable tolerability of the combination."

Enrollment is accelerating, and 45 patients have been enrolled. Correlative analyses of peripheral blood and tumor tissue biomarkers are ongoing. The Company is planning to present more mature data at an oncology conference later this year. The Company expects to meet with regulatory authorities in the second half of 2018 to discuss plans for registration.

In a separate Phase 2 study, mocetinostat is being evaluated in combination with durvalumab (IMFINZI), an anti-PD-L1 checkpoint inhibitor, in patients with NSCLC who have experienced documented disease progression following prior treatment with a checkpoint inhibitor. As of the data cutoff date of March 31, 2018:

23 patients were evaluable for response with at least one radiographic scan

Three patients achieved a PR (two confirmed and one unconfirme

All three patients with PRs remain on study; the longest treatment duration exceeds 44 weeks and is ongoing
8 of 23 patients demonstrated tumor reductions.

To date, the combination has been well-tolerated, and most AEs reported by investigators were Grade 1 or 2.
31 patients have been enrolled in this ongoing trial and the Company plans to present more mature data at an oncology conference later this year.
Mirati also provided an update on the Phase 1b expansion trial for sitravatinib as a single agent. Interim clinical data will be presented in a poster at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting held June 1 – 5, 2018 in Chicago, Illinois. The presentation, titled "Evaluation of the spectrum selective RTK inhibitor sitravatinib in renal cell carcinoma (RCC) refractory to anti-angiogenic therapy" will report data from patients with RCC treated with single agent sitravatinib.

In that same Phase 1b trial of single agent sitravatinib, enrollment continues in the cohorts of patients whose tumors harbor CBL, CHR4Q12 and RET genetic alterations in NSCLC and other tumor types. The Company plans to present more mature data for these patients at an oncology conference later this year.

MRTX849, the Company’s small molecule mutation-selective KRAS G12C inhibitor, continues to advance towards a planned Investigational New Drug (IND) submission in the fourth quarter of 2018, with the potential to generate early proof-of-concept clinical data in 2019.

About Sitravatinib

Sitravatinib is a spectrum-selective kinase inhibitor that potently inhibits receptor tyrosine kinases (RTKs), including TAM family receptors (TYRO3, Axl, Mer), split family receptors (VEGFR2, KIT) and RET. As an immuno-oncology agent, sitravatinib is being tested in combination with nivolumab (OPDIVO), an anti-PD-1 checkpoint inhibitor, in NSCLC patients who have experienced documented disease progression following treatment with a checkpoint inhibitor. Sitravatinib’s potent inhibition of TAM and split family RTKs may overcome resistance to checkpoint inhibitor therapy through targeted reversal of an immunosuppressive tumor microenvironment, enhancing antigen-specific T cell response and expanding dendritic cell-dependent antigen presentation.

Sitravatinib is also being evaluated as a single agent in a Phase 1b expansion trial enrolling patients whose tumors harbor CBL, CHR4Q12 and RET genetic alterations in NSCLC and other solid tumors.

About Mocetinostat

Mocetinostat is a selective Class I and IV HDAC inhibitor. Inhibition of histone acetylation is predicted to enhance the recognition of tumor cells by anti-tumor T cells and reverse immunosuppressive factors in the tumor microenvironment. The Company is conducting a Phase 2 study of mocetinostat in combination with durvalumab (IMFINZI), an anti-PD-L1 checkpoint inhibitor, in NSCLC patients who have experienced disease progression following prior treatment with a checkpoint inhibitor.

About MRTX849

MRTX849 is an orally-available small molecule that potently and selectively inhibits a form of KRAS which harbors a substitution mutation (G12C). KRAS G12C mutations are present in approximately 14% of NSCLC adenocarcinoma patients and 5% of colorectal cancer patients. Tumors characterized by KRAS G12C mutations are commonly associated with poor prognosis and resistance to therapy, and patients with these mutations have few treatment options. MTRX849 has demonstrated complete regression of KRAS G12C-positive human tumors implanted in mice. IND-enabling preclinical studies are underway, and an IND submission is expected in the fourth quarter of 2018, with early clinical proof-of-concept anticipated in 2019.

The study titled, "Improved identification of high-risk, Stage I-II cutaneous melanomas with the combination of American Joint Committee on Cancer staging and a 31-gene expression profile test result," was presented as a poster at the 3rd Annual Real World Dermatology for Physician Assistants and Nurse Practitioners conference, held April 20-22, 2018 in Orlando, Florida.

"In this large Stage I-II melanoma study population, the DecisionDx-Melanoma test improved risk prediction when used in combination with AJCC risk assessment and showed independent prognostic value," commented study co-author Robert W. Cook, PhD, Vice President, Medical Affairs and R&D at Castle Biosciences. "Providing this information for risk assessment is important to help guide patient management decisions for improved patient outcomes."

Study Background

For patients with cutaneous melanoma, accurate assessment of recurrence risk is important to guide management plans including imaging based surveillance, follow-up frequency and sentinel lymph node biopsy recommendations that can lead to early detection of metastatic disease. National guidelines suggest surveillance plans based on AJCC stage, with Stage I-IIA considered low risk and Stage IIB-IV considered high risk. The DecisionDx-Melanoma GEP test accurately and independently predicts risk of recurrence and metastasis, classifying patients as Class 1A (lowest risk) Class 1B/2A (lower or intermediate risk) or Class 2B (highest risk).

This study of 485 Stage I and II patients from a multicenter cohort with long-term outcomes assessed the use of AJCC staging combined with results from the DecisionDx-Melanoma GEP test to improve recurrence risk prediction.

Key Study Findings:

Patients who were classified as high risk by both AJCC staging (Stage IIB-C) and the GEP test (Class 2B) had significantly lower 5-year recurrence-free survival (RFS 33.4%), distant metastasis-free survival (DMFS 49.5%) and melanoma specific survival (MSS 86.7%) compared to those identified as low risk by both methods (RFS 96.1%, DMFS 97.3%, MSS 99.6%, p<0.0001 for all comparisons).
Importantly, patients who were assessed as low risk using AJCC staging (Stage I-IIA) but high risk using the GEP test also demonstrated significantly worse outcomes (RFS 60.9%, DMFS 75.8%, MSS 85.9%) compared to patients who were assessed as low risk using both methods (p<0.0001 for all comparisons).
Multivariate Cox regression analysis indicated that both GEP high risk and AJCC high risk were significant and independent predictors of RFS (GEP HR 6.8; AJCC HR 2.98, p<0.0001, both groups) and DMFS (GEP HR 8.5; AJCC HR 2.5, p<0.001, both groups). For MSS, GEP Class 2B was the only significant predictor (GEP HR 43.8, p<0.001; AJCC HR 1.04, p<0.94).
Clinical Impact of DecisionDx-Melanoma Test

A second poster titled, "Clinical impact of a 31-gene expression profile test for cutaneous melanoma patients: a review of clinical utility studies," was also presented at the conference.

The poster highlights key findings across 5 published clinical utility studies, including:

In prospective and retrospective multicenter clinical utility studies, the inclusion of the DecisionDx-Melanoma test in risk assessment resulted in significant differences in follow-up and surveillance when comparing low- and high-risk patients.
Findings across multiple clinical impact studies show that incorporation of the GEP test consistently impacts clinical management decisions for approximately 1 in 2 patients tested.
Use of the DecisionDx-Melanoma GEP test in combination with conventional staging methods can help develop a more efficient and individualized follow-up plan based on clinical factors and tumor biology.
About DecisionDx-Melanoma
The DecisionDx-Melanoma test uses tumor biology to predict individual risk of melanoma recurrence and sentinel lymph node positivity independent of traditional factors. Using tissue from the primary melanoma, the test measures the expression of 31 genes. The test has been validated in three multicenter studies that have included 690 patients and have demonstrated consistent results. Performance has also been confirmed in four prospective studies including 702 patients. The consistent high performance and accuracy demonstrated in these studies, which combined have included over 1,300 patients, provides confidence in disease management plans that incorporate DecisionDx-Melanoma test results. Prediction of the likelihood of sentinel lymph node positivity has also been validated in two prospective multicenter studies which included over 1,400 patients. Clinical impact has been demonstrated in multicenter and single-center studies showing that test results impact clinical management decisions for one of every two patients tested. More information about the test and disease can be found at www.SkinMelanoma.com.
