Business Overview and History:
Verastem Oncology, a late-stage biopharmaceutical company, is making waves in the oncology landscape with its innovative approach to targeting KRAS-driven cancers. With a deep pipeline of novel drug candidates and a relentless focus on advancing the standard of care, Verastem is poised to transform the lives of patients battling some of the most challenging cancer types.
Verastem was founded in 2010 with a mission to develop new medicines that improve the lives of patients diagnosed with cancer. The company has focused its pipeline on RAS mitogen activated pathway kinase (MAPK) driven cancers, with a particular emphasis on novel drug candidates that inhibit signaling pathways critical to cancer cell survival and tumor growth.
Verastem's most advanced product candidates are avutometinib and defactinib. Avutometinib is an orally available, first-in-class, small molecule RAF/MEK clamp that inhibits the RAS/RAF/MEK/ERK MAPK pathway, which is involved in the proliferation, migration, transformation, and survival of tumor cells. Defactinib is an oral small molecule inhibitor of focal adhesion kinase (FAK) and proline-rich tyrosine kinase (PYK2) that is being evaluated as a potential combination therapy for various solid tumors.
The company has faced several challenges over the years, including the failure of its lead product candidate, defactinib, in a Phase 3 clinical trial for mesothelioma in 2018. Verastem also encountered difficulties with the commercialization of COPIKTRA (duvelisib), which was approved by the FDA in 2018 for the treatment of certain blood cancers. In 2020, Verastem made the strategic decision to sell its exclusive worldwide license, including related assets, for the research, development, commercialization, and manufacture in oncology indications of products containing duvelisib to Secura Bio, Inc. This transaction allowed Verastem to focus its resources on the development of avutometinib and defactinib.
Despite these setbacks, Verastem has continued to advance its pipeline, with avutometinib and defactinib being investigated in both preclinical and clinical studies for the treatment of various solid tumors, including low-grade serous ovarian cancer, non-small cell lung cancer, pancreatic cancer, colorectal cancer, and thyroid cancer.
Financial Overview:
As of June 30, 2024, Verastem reported cash, cash equivalents, and investments of $83.4 million. The company's net loss for the six months ended June 30, 2024, was $42.1 million, with a net loss per share of $1.57. Verastem's research and development expenses for the same period were $35.8 million, while selling, general, and administrative expenses were $20.6 million.
For the most recent fiscal year 2023, Verastem reported no revenue, a net loss of $87,367,000, operating cash flow of -$86,460,000, and free cash flow of -$86,460,000. In the most recent quarter (Q1 2024), the company reported revenue of $10,000,000, a net loss of $8,256,000, operating cash flow of -$27,570,000, and free cash flow of -$27,577,000. The increase in revenue compared to the prior year quarter was due to a $10 million milestone payment received from Secura after they achieved cumulative worldwide net sales of COPIKTRA exceeding $100 million. The increase in net loss and decrease in operating and free cash flow was primarily driven by higher research and development expenses related to the ongoing clinical trials for the company's lead product candidates, avutometinib and defactinib.
In July 2024, Verastem announced the successful completion of a $51.1 million public offering, which bolstered the company's financial position and provided additional resources to advance its clinical programs.
As of June 30, 2024, Verastem had a debt-to-equity ratio of 1.05 and $241,000 in restricted cash. The company also has a loan and security agreement with Oxford Finance, under which it had $40 million in principal debt outstanding as of June 30, 2024. Verastem's current ratio and quick ratio both stand at 3.28, indicating a strong short-term liquidity position.
Pipeline and Clinical Progress:
Avutometinib, Verastem's lead RAFMEK clamp inhibitor, is being evaluated in various clinical trials for the treatment of solid tumors. The company's most advanced program is the RAMP 201 study, a registration-directed trial investigating avutometinib, both as a monotherapy and in combination with defactinib, for the treatment of patients with recurrent LGSOC.
In May 2024, Verastem announced updated results from the RAMP 201 study, which demonstrated encouraging efficacy and safety data. The combination of avutometinib and defactinib achieved an overall response rate of 27% in all patients, with higher response rates observed in the KRAS mutant (37%) and KRAS wild-type (15%) populations. The majority of patients (60%) achieved either a complete response, partial response, or stable disease lasting 6 months or longer.
Based on these positive results, Verastem initiated a rolling New Drug Application (NDA) submission to the FDA in May 2024, seeking accelerated approval for the avutometinib and defactinib combination in patients with recurrent KRAS mutant LGSOC. The company is also planning to discuss the regulatory path forward with global authorities, including in Europe and Japan, to potentially expand the availability of this treatment option. Verastem plans to request priority review of the NDA.
In addition to the RAMP 201 study, Verastem is investigating avutometinib in combination with other targeted therapies, such as KRAS G12C inhibitors and immunotherapies, through various investigator-sponsored trials and collaborative efforts. These studies aim to leverage the synergistic potential of combining avutometinib's RAFMEK inhibition with other targeted agents to enhance anti-tumor activity in a range of solid tumors.
The combination of avutometinib and defactinib has received breakthrough designation from the FDA for the treatment of recurrent LGSOC, regardless of KRAS status, after one or more prior lines of therapy including platinum-based chemotherapy. Avutometinib and the combination with defactinib have also received orphan drug designations in the US for the treatment of LGSOC.
Market Opportunity and Potential:
Verastem estimates the total annual incident addressable market opportunity for the combination of avutometinib and defactinib to be approximately $300 million for KRAS mutant and $270 million for KRAS wild-type LGSOC populations, respectively. The total prevalent addressable market opportunity is estimated to be approximately $1.7 billion for KRAS mutant and $1.1 billion for KRAS wild-type LGSOC populations.
These estimates underscore the significant potential for Verastem's lead product candidates in the LGSOC market, which represents an area of high unmet medical need. The company's focus on precision oncology and its unique approach to targeting the RAS-MAPK and FAK pathways position it as a promising player in this space.
