SAN DIEGO, Aug. 6, 2015 /PRNewswire/ -- Mirati Therapeutics, Inc. (“Mirati”) (NASDAQ: MRTX) today reported financial results for the second quarter ended June 30, 2015 and provided an update on its drug development programs.
“At this year’s ASCO meeting, we presented initial clinical data on our lead tyrosine kinase inhibitor, MGCD265, which clearly demonstrated significant tumor regression in non-small lung cancer patients with MET gene alterations. With pre-clinical and clinical data showing anti-tumor activity, we are confident that targeting MET driver alterations is a clinically valid approach, and we look forward to initiating a Phase 2 registration-enabling study by the end of the year,” said Charles M. Baum, M.D., Ph.D., president and CEO, Mirati. “We also recently announced a clinical trial collaboration with our spectrum-selective HDAC inhibitor, mocetinostat. The Phase 1-2 study will evaluate the safety and efficacy of mocetinostat, in combination with durvalumab, an investigational anti-PD-L1 immune checkpoint inhibitor, in patients with non-small cell lung cancer. We are excited about this combination, as mocetinostat may enhance the efficacy of immune checkpoint inhibitors, potentially leading to improved therapies for patients.”
Recent and Upcoming Pipeline Highlights
MGCD265: Molecularly targeted kinase inhibitor
- 2015 American Society of Clinical Oncology (ASCO) Annual Meeting: Presented data demonstrating preliminary evidence of clinical activity in non-small cell lung cancer (NSCLC) patients, including clear tumor regression and improvement in clinical symptoms such as pain and shortness of breath
- The first three patients selected for MET gene alterations in the dose expansion cohort showed clear evidence of tumor regression as early as the first scan. All three patients have extensive disease and failed several prior therapies before being treated with MGCD265
- Demonstrated that MGCD265 was well tolerated
- The poster can be found on the Company’s website at www.mirati.com
- Additional information about this clinical trial of MGCD265 is available at www.clinicaltrials.gov using identifier: NCT00697632
- The Company expects to initiate a single arm Phase 2 registration-enabling study in NSCLC by the end of the year
MGCD516: Molecularly targeted kinase inhibitor
- 2015 ASCO Annual Meeting: Presented the clinical trial design of the Phase 1, open label, single agent study designed to evaluate the safety, pharmacokinetics/pharmacodynamics (PK/PD) and clinical activity of MGCD516 in patients with advanced solid tumors, with an initial focus on NSCLC
- The poster can be found on the Company’s website at www.mirati.com
- Additional information about this clinical trial of MGCD516 is available at www.clinicaltrials.gov using identifier: NCT02219711
- The Company expects to establish a Phase 2 dose and initiate expansion cohorts in selected patients by the end of the year
Mocetinostat: Molecularly targeted epigenetic inhibitor
Announced a clinical trial collaboration to evaluate the safety and efficacy of mocetinostat in combination with durvalumab (MEDI4736), an investigational anti-PD-L1 immune checkpoint inhibitor. The initial Phase 1-2 study will be evaluated in patients with NSCLC
- 2015 Annual ASCO Meeting: Presented the clinical trial design of the mocetinostat Phase 2 study in patients with previously treated, locally advanced, unresectable or metastatic urothelial carcinoma of the bladder harboring inactivating mutations or deletions of the histone acetyltransferase genes CREBBP and/or EP300
- The poster can be found on the Company’s website at www.mirati.com
- Additional information about this clinical trial of mocetinostat is available at www.clinicaltrials.gov using identifier: NCT02236195
- The two Phase 2 trials evaluating mocetinostat (one in bladder cancer, the other in diffuse large B-cell lymphoma and follicular lymphoma) are ongoing with initial clinical data anticipated later in the year
Second Quarter 2015 Financial Results
Cash, cash equivalents, and short-term investments were $58.9 million at June 30, 2015, compared to $29.3 million at December 31, 2014. In February 2015, the Company successfully completed a public offering of 2.6 million shares of its common stock, generating net proceeds of $48.4 million.
Research and development expenditures for the second quarter of 2015 were $11.3 million, compared to $7.1 million for the same period in 2014. Research and development expenses for the six months ended June 30, 2015 were $19.5 million, compared to $12.1 million for the same period in 2014. The increases in research and development expenses primarily reflect costs to advance the clinical development of its three oncology development programs, MGCD265, MGCD516 and mocetinostat. General and administrative expenses for the first quarter of 2015 were $4.2 million, compared to $3.0 million for the same period in 2014. General and administrative expenses for the six months ended June 30, 2015 were $8.0 million, compared to $5.7 million for the same period in 2014. The increases in general and administrative expenses primarily reflect higher, non-cash stock-based compensation expense.
Other income and expense, net, for the second quarter of 2015 was income of $0.1 million compared to expense of $0.9 million for the same period in 2014. Other income and expense, net, for the six months ended June 30, 2015 was income of $0.1 million compared to expense of $6.6 million for the same period in 2014. Other income and expense, net, for the second quarter and six months ended June 30, 2014 primarily reflects losses arising from the change in fair value of our warrant liability. During 2014, we amended the warrant agreements to allow for the warrants to be denominated in U.S. dollars. The amended warrants qualified for equity classification and were reclassified into stockholders’ equity.
Net loss for the second quarter of 2015 was $15.4 million, or $0.95 per share, compared to net loss of $11.0 million, or $0.82 per share for the same period in 2014.
