7. | Commitments and Contingencies
We have entered into agreements with various research organizations for pre-clinical and clinical development studies, which have provisions for cancellation. Under the terms of these agreements, the vendors provide a variety of services including conducting research, recruiting and enrolling patients, monitoring studies and data analysis. Payments under these agreements typically include fees for services and reimbursement of expenses. The timing of payments due under these agreements is estimated based on current study progress. As of December 31, 2017, we have clinical research study obligations of $0.6 million, all of which are expected to be complete within a year. Should the timing of the clinical trials change, the timing of the payment of these obligations would also change. We lease facilities for our headquarters office location as well as international office locations. As of December 31, 2017, we have contractual lease obligations to make payments on leases of office and manufacturing space as follows:
Years Ending December 31, |  |  | Obligation |
2018 |  | $ | 589 |
2019 |  |  | 565 |
2020 |  |  | 541 |
2021 |  |  | 541 |
2022 |  |  | 138 |
Total |  | $ | 2,374 |
Rent expense, which includes common area maintenance, for the years ended December 31, 2017 and 2016 was $2.2 million and $2.5 million, respectively. On February 27, 2017, we entered into a Lease Agreement of office space for our corporate headquarters in San Diego, California (the “Lease”). The initial term of the Lease is 63 months and may be extended upon mutual agreement. The commencement date was originally expected to take place in November 2017 and subsequently amended to January 1, 2018. In connection with our restructuring announced in September 2017, we began negotiations with the landlord and in February 2018, announced a buy-out of our obligations with the Lease of approximately $0.6 million. On January 27, 2017, we entered into a Lease Agreement of office space for our office in Tokyo, Japan (the “Japan Lease”). The initial term of the Japan Lease is 61 months, and may be extended upon mutual agreement. The Lease commenced on April 15, 2017. We are party to an agreement with Roche Diagnostics Corporation, our sole supplier of reagents, which requires us to make certain product purchase minimums until 2020. Pursuant to the agreement, as of December 31, 2017, we have a minimum purchase obligation as follows:
Years Ending December 31, |  |  | Obligation |
2018 |  | $ | 1,074 |
2019 |  |  | 1,473 |
2020 |  |  | 1,473 |
Total |  | $ | 4,020 |
We are subject to various claims and contingencies related to legal proceedings. Due to their nature, such legal proceedings involve inherent uncertainties including, but not limited to, court rulings, negotiations between affected parties and governmental actions. Management assesses the probability of loss for such contingencies and accrues a liability and/or discloses the relevant circumstances, as appropriate. Management believes that any liability to us that may arise as a result of currently pending legal proceedings will not have a material adverse effect on our financial condition, liquidity, or results of operations as a whole.
