Sorrento’s response:
The Company respectfully acknowledges the Staff’s comment, advises the Staff that the Company will enhance its disclosure in future filings to quantify the noted factors and notes that it has included the following disclosures in the Management’s Discussion and Analysis section of the Company’s Form 10-Q for the quarter ended June 30, 2022 filed with the SEC on August 15, 2022 (the “Q2 2022 Form 10-Q”).
Selling, General and Administrative (“SG&A”) Expenses
The decrease in SG&A expenses in our Sorrento segment during the three months ended June 30, 2022 was attributed to lower professional fees, including a decrease in legal and consulting costs by approximately $6.4 million, and lower stock-based compensation expenses of $2.9 million. Personnel costs and infrastructure-related expenses increased by $2.1 million and $1.6 million, respectively, compared to the same period of the prior year.
The decrease in SG&A expenses in our Sorrento segment during the six months ended June 30, 2022 was attributed to lower professional fees, including a decrease in legal and consulting costs, by approximately $4.8 million, and lower stock-based compensation expenses of $5.7 million. Personnel costs and infrastructure-related expenses increased by $6.9 million and $1.1 million, respectively, compared to the same period of the prior year.
For the three and six months ended June 30, 2022, the increases in SG&A expenses in our Scilex segment were attributed to increases in personnel costs and professional fees compared to the same periods of the prior year.
| 2. | You disclosed that research and development expenses for your Sorrento Therapeutics segment increased by $96.3 million as compared to the prior fiscal year and were primarily driven by higher headcount and increased clinical development costs spent on advancing your various research and development programs. As research and development expenses constitute your most significant expense in the periods presented, please provide us proposed disclosure to be provided in future filings the costs incurred during each period presented for each of your key research and development projects. If you do not track your research and development costs by project, please disclose that fact and explain why you do not maintain and evaluate research and development costs by project. Provide other quantitative or qualitative disclosure that provides more transparency as to the type of research and development expenses incurred (i.e. by nature or type of expense) which should reconcile to total research and development expense on the Statements of Operations. |
Sorrento’s response:
The Company respectfully acknowledges the Staff’s comment, advises the Staff that the Company will enhance the disclosure in its future filings to discuss in more detail the research and development expenses for each period presented and notes that it has included the following disclosures in the Management’s Discussion and Analysis section of the Q2 2022 Form 10-Q:

R&D expenses include expenses associated with isolating and advancing human antibody drug candidates derived from our libraries, as well as advancing our COVID-19, SP-102, SP-103, RTX, oncolytic virus, ADC and oncology programs. Such expenses consist primarily of salaries and personnel-related expenses, stock-based compensation expense, clinical development expenses, preclinical testing, lab supplies, consulting costs, depreciation and other expenses. We track external development costs by program; however, we do not allocate laboratory supplies, R&D materials, personnel costs, share-based payments, facilities costs or other internal costs to specific development programs.

Third party clinical and pre-clinical R&D expenses for our Sorrento segment largely fluctuated as a result of the timing of clinical trial spend and the timing of our acquisition of ACEA Therapeutics, Inc. (“ACEA”) (Abivertinib), which occurred in June 2021. Salaries, personnel costs and facilities expenses increased as compared to the same periods in the prior year as we continue expanding our R&D personnel headcount and infrastructure to support our R&D programs.
