Financial Obligations and Agreements - The company has paid an initial upfront payment of $5.0 million to Daiichi Sankyo and is obligated to make future milestone payments of up to $222.5 million[51]. - The royalty obligation to Daiichi Sankyo is a high single-digit percentage based on annual net sales of milademetan products, with no payments made to date[53]. - The company is required to pay Drexel a low single-digit royalty on net sales of licensed products, with a minimum quarterly royalty payment of $6,250[58]. - The Drexel License Agreement includes a one-time initiation fee of $20,000 and milestone payments up to $6.25 million for achieving specified development and regulatory milestones[58]. - The Daiichi Sankyo License Agreement remains effective until all development and commercial activities related to the Licensed Compound cease, with termination rights for both parties under specific conditions[54]. Regulatory and Compliance - The company must conduct preclinical studies and submit an Investigational New Drug (IND) application to the FDA before initiating human clinical trials[82]. - The FDA may impose a clinical hold on trials, delaying or suspending investigations based on safety concerns[84]. - The FDA conducts preliminary reviews of NDAs within 60 days and may request additional information before accepting an application for substantive review[95]. - The FDA typically inspects manufacturing facilities and clinical sites for compliance with current good manufacturing practices (cGMP) before approving an NDA[97]. - The FDA may issue an approval letter or a complete response letter based on the evaluation of the NDA, with the latter indicating deficiencies that need to be addressed before reconsideration[99]. - The company must maintain compliance with extensive regulations governing manufacturing processes and quality control[65]. - The company is subject to extensive government regulations regarding drug development, testing, and marketing, requiring significant time and financial resources[80]. Intellectual Property - The patent portfolio for milademetan includes fourteen issued U.S. patents and ninety-seven issued foreign patents, all exclusively licensed from Daiichi Sankyo, with expiration expected in March 2032 for certain patents[71]. - The RAD52 program has two patent families directed to RAD52 inhibitors, with one family comprising two issued U.S. patents expected to expire in June 2036[74]. - The company intends to apply for patent term extensions for its drug candidates upon receiving FDA approval, which may extend the patent term by up to five years, but not beyond a total of 14 years from the date of product approval[78]. Market and Competitive Landscape - The company focuses on developing precision small molecule therapies for cancers with high unmet medical needs, competing against numerous other companies in this space[180]. - The lead product candidate, milademetan, targets MDM2, with no approved drugs currently available for this target, although several companies are testing MDM2 inhibitors[181]. - The RAD52 program is currently the most advanced program targeting RAD52, with no other approved or clinical-stage therapeutics available[182]. - The company faces competition from larger firms with greater financial resources and expertise in research and development, which may impact its market opportunities[183]. Workforce and Company Culture - The company had 44 full-time employees as of December 31, 2021, with 31 in research and development and 13 in general and administrative roles[185]. - 48% of the company's employees are women, and they speak over 21 languages, reflecting a diverse workforce[188]. - The company is committed to providing a safe and healthy work environment, especially during the COVID-19 pandemic, with most employees working remotely[192]. - The company emphasizes the importance of recruiting and retaining qualified scientific personnel to ensure business success[185].
