General and administrative expenses
General and administrative expenses for the six months ended June 30, 2022 were approximately $6,069,000 compared to approximately $4,166,000 for the six months ended June 30, 2021. This increase of 46% or $1,903,000 was primarily due to hiring a new Chief Executive Officer in March 2022 and the departure of the previous CEO, as well as increased consulting fees for services such as strategic advisory, investor relations, and other activities.
We expect our general and administrative expenses to increase due to increased staffing, legal, accounting and professional fees associated with being a publicly reporting company in the United States, and to support the Company’s operational plans and anticipated growth.
Other income (expense)
Other income for the six months ended June 30, 2022 was approximately $204,000 compared to other expense of approximately $306,000 for the six months ended June 30, 2021. This $510,000 increase was primarily attributed to foreign currency exchange gains in the current period as compared to foreign currency exchange losses in the prior period.

We believe our current capital resources are sufficient to support our operations into June 2023 .
We are subject to a number of risks similar to those of clinical stage companies, including dependence on key individuals, uncertainty of product development and generation of revenues, dependence on outside sources of `capital, risks associated with clinical trials of products, dependence on third-party collaborators for research operations, need for marketing authorization of products, risks associated with protection of intellectual property, and competition with larger, better-capitalized companies. We are closely monitoring ongoing developments in connection with the COVID-19 pandemic, which has resulted in disruptions to and the halting of previous clinical trials and may negatively impact our ability to raise capital. To fully execute our business plan, we will need, among other things, to complete our research and development efforts and clinical and regulatory activities. These activities may take several years and will require significant operating and capital expenditures in the foreseeable future.
For the six months ended June 30, 2022, we reported a net loss of $10,856,373 and we expect to continue to incur substantial losses over the next several years during our development phase. To fund our capital needs, we plan to raise additional funds through
