7.2 Hospital Right to Prosecute. Company may and shall have the first right to, upon notice to Hospital, initiate legal proceedings against the infringer at Company’s expense with respect to a claim of a Patent Right in the License Field in the License Territory. Or, in the event Company notifies Hospital that Company does not intend to prosecute infringement identified under Section 7.1, Hospital may, upon notice to Company, initiate legal proceedings against the infringer at Hospital’s expense with respect to a claim of a Patent Right in the License Field in the License Territory.

Before commencing an infringement action, Company and, as applicable, any Affiliate, shall consult with Hospital, concerning, among other things, Company’s standing to bring suit, the advisability of bringing suit, the selection of counsel and the jurisdiction for such action (provided Company must have Hospital’s reasonable prior written consent with respect to selection of jurisdiction for any action in which Hospital may be joined as a party-plaintiff) and shall use reasonable efforts to accommodate the views of Hospital regarding the proposed action, including without limitation with respect to potential effects on the public interest. Company shall be responsible for all costs, expenses and liabilities in connection with any such action and shall indemnify and hold Hospital harmless therefrom, regardless of whether Hospital is a party-plaintiff, except for the expense of any independent counsel retained by Hospital in accordance with Section 7.5 below.

If Hospital makes such an assignment, such action by Company shall thereafter be brought or continued without Hospital as a party; provided, however, that Hospital shall continue to have all rights of prosecution and maintenance with respect to Patent Rights and Company shall continue to meet all of its obligations under this Agreement as if the assigned Patent Right were still licensed to Company hereunder.

7.4 Notice of Actions; Settlement. Company shall promptly inform Hospital of any action or suit relating to Patent Rights and shall not enter into any settlement, consent judgment or other voluntary final disposition of any action relating to Patent Rights, including but not limited to appeals, without the prior written consent of Hospital.

7.5 Cooperation. Each Party agrees to cooperate reasonably in any action under Section 7 which is controlled by the other Party, provided that the controlling party reimburses the cooperating party for any costs and expenses incurred by the cooperating party in connection with providing such assistance, except for the expense of any independent counsel retained by the cooperating party in accordance with this Section 7.5. Such controlling party shall keep the cooperating party informed of the progress of such proceedings and shall make its counsel available to the cooperating party. The cooperating party shall also be entitled to independent

counsel in such proceedings but at its own expense, said expense to be offset against any damages received by the Party bringing suit in accordance with Section 7.6.

7.6 Recovery. Any award paid by third parties as the result of such proceedings (whether by way of settlement or otherwise) shall first be applied to reimbursement of any legal fees and expenses incurred by either Party, and then the remainder shall be divided between the Parties as follows:

(a) (i) Company shall receive an amount equal to its lost profits or a reasonable royalty on the infringing sales , or whichever measure of damages the court shall have applied; and

(ii) Hospital shall receive an amount equal to the royalties and other amounts that Company would have paid to Hospital if Company had Sold the infringing Products and Services rather than the infringer; and

(b) Company agrees, at its own expense, to provide attorneys reasonably acceptable to the Hospital and BIDMC to defend against any actions brought or filed against any party indemnified hereunder with respect to the subject of indemnity contained herein, whether or not such actions are rightfully brought; provided, however, that any Indemnitee shall have the right to retain its own counsel, at the expense of Company, if representation of such Indemnitee by counsel retained by Company would be inappropriate because of conflict of interests of such Indemnitee and any other party represented by such counsel. Company agrees to

keep Hospital and BIDMC informed of the progress in the defense and disposition of such claim and to consult with Hospital and BIDMC prior to any proposed settlement.

8.2 Insurance.

(a) Beginning at such time as any such licensed Product or Process is being commercially distributed, sold, leased or otherwise transferred, or performed or used (other than for the purpose of obtaining regulatory approvals), by Company, an Affiliate or Sublicensee, Company shall, at its sole cost and expense, procure and maintain commercial general liability insurance in amounts not less than $2,000,000 per incident and $2,000,000 annual aggregate and naming the Indemnitees as additional insureds. Such commercial general liability insurance shall provide (i) product liability coverage and (ii) broad form contractual liability coverage for Company’s indemnification under Section 8.1 of this Agreement. If Company elects to self-insure or have Affiliates or Sublicensees arrange for self-insurance including Company’s obligations hereunder all or part of the limits described above (including deductibles or retentions which are in excess of $250,000 annual aggregate) such self-insurance program must be acceptable to the Hospital and the Risk Management Foundation. The minimum amounts of insurance coverage required under this Section 8.2 shall not be construed to create a limit of Company’s liability with respect to its indemnification under Section 8.1 of this Agreement.

(b) Company shall provide Hospital with written evidence of such insurance upon request of Hospital. Company shall provide Hospital with written notice at least fifteen (15) days prior to the cancellation, non-renewal or material change in such insurance; if Company does not obtain replacement insurance providing comparable coverage prior to the expiration of such fifteen (15) day period, Hospital shall have the right to terminate this Agreement effective at the end of such fifteen (15) day period without notice or any additional waiting periods.

(c) Company shall maintain such commercial general liability insurance beyond the expiration or termination of this Agreement during (i) the period that any such licensed Product or Process is being commercially distributed, sold, leased or otherwise transferred, or performed or used (other than for the purpose of obtaining regulatory approvals), by Company or by a licensee, affiliate or agent of Company and (ii) a reasonable period after the period referred to in (c) (i) above which in no event shall be less than fifteen (15) years.

(d) This section 8.2 shall survive expiration or termination of this Agreement.

DEVELOPMENT PLAN

Pseudomonas Monoclonal Antibody Product Development Plan

Background

Pseudomonas aeruginosa, a ubiquitous gram negative bacterium, has been identified as one of six “superbugs” on the “hit list” of top priority, dangerous pathogens that are becoming increasingly drug resistant”1,2. P. aeruginosa is also the most prevalent/causative pathogen in multi-drug resistant lung infections exceeding even MRSA. P. aeruginosa is an opportunistic pathogen that is a significant problem for critically ill or immunocompromised individuals and poses a particular threat for patients with lung infections, i.e., Hospital acquired gram negative pneumonias (HAP) including: ventilator associated pneumonia (VAP), Healthcare Associated Pneumonia (HCAP), non-CF bronchiectasis and chronic obstructive pulmonary disease (COPD). CF patients, in particular, are susceptible to chronic P. aeruginosa infections with over 80% of adult CF patients chronically infected with P. aeruginosa. Although several inhaled antibiotics, i.e., TOBI, aztreonam, amikacin, ciprofloxacin, have been, or are being developed to treat lung infections their use is limited by antibiotic resistance (both at the institutional and societal level) and in some cases the potential nephrotoxicity and ototoxicity associated with their long term use. Drug resistance is not expected to be a problem with Aerucin, since any selective pressure that may down-regulate alginate expression would result in less virulent non-mucoid Pa strains, which are more susceptible to conventional antibiotics.

Alginate expression is key to colonization, biofilm growth, virulence & immune evasion. The mucoid phenotype involves upregulating its secretion, which consists of 0-1, 4-linked D-mannuronic acid and L-guluronic acid and confers resistance to antibiotics5. In a small subset of adult CF patients, there is a class of phagocytic antibodies (i.e. they activate engulfment and destruction by immune cells) directed against alginate that appear to play a protective role. These patients are not colonized with mucoid P. aeruginosa, have better lung function than chronically colonized patients6, and have a specific class of anti-alginate antibodies that mediate phagocytic killing. Aerucin™ binds to the carboxyl group of the C6 of alginate mannuronic acid, an epitope that is conserved on all Pa alginate, and mediates complement dependent phagocytic killing of both mucoid and non-mucoid P. aeruginosa.

There are multiple therapeutic areas in which P. aeruginosa is a significant pathogen, which can be categorized according to the site of infection. We plan to initially develop these mAbs for lung infections, which are characterized by individuals in a weakened state due to chronic disease or intubation that leaves them particularly susceptible to P. aeruginosa infections. The initial indication will be hospital acquired Gram Negative Pneumonias including ventilator associated pneumonia (VAP), Healthcare Associated Pneumonias (HCAP), and Severe Community Acquired Pneumonias (CAP) with suspected P. aeruginosa8. Subsequently, we will investigate non-CF bronchiectasis, chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF).

Business Opportunity in Lung Infections

Lung infection markets are characterized by patients who either have a disruption of the normal protective barrier to infection such as hospital acquired pneumonias or have an underlying chronic disease (CF, non-CF bronchiectasis and COPD) that in any case leaves their lungs in a weakened state and susceptible to infections by P. aeruginosa. Additionally, those patients who are at highest risk for a hospital acquired pneumonia or health care associated pneumonia can be often overlooked if a careful patient history is not conducted. Each of these offers a specific opportunity to treat the infection and improve the disease outcome. The combined market for lung infections is a multi-billion dollar opportunity. With respect to Aerucin and our initial market focus in gram negative pneumonias, we project that Aerucin could achieve in excess of $800 Million globally and possibly greater with a comprehensive phase III development program for Gram negative pneumonias and CF.

Aerucin™ for Gram Negative Hospital Acquired Pneumonias

Nosocomial infections result from treatment in a hospital or hospital-like setting, but are secondary to the patient’s original condition. Direct mortality to HAP is ~50% with approximately 21% of all HAP caused by P. aeruginosa infections. AerucinTM is ideally suited for use in ventilated patients with gram negative pneumonia to improve the clinical outcome and limit systemic exposure to antibiotics. Additionally, a clinical development plan that includes intravenous or inhalation administration (wet or dry application) of Aerucin post extubation potentially improves therapeutic outcomes (full course of therapy) and expands the market opportunity for Aerucin either as continuation therapy or as initial therapy in patients where mechanical ventilation could be avoided by earlier treatment and improved efficacy in moderate to severe gram negative pneumonias.

Aerucin™ for the treatment of lung infections in CF patients

Aerucin can be given under both therapeutic and prophylactic modalities. This is because CF patients are initially infected with non-mucoid P. aeruginosa strains at an early age (median age of 13 months), which then convert to a chronic infection with mucoid strains in >80% of CF patients by 18 years of age”. Thus, Aerucin™ can be used to either prevent the initial infection with P. aeruginosa or therapeutically to control or eradicate the infection. The potential for formulation flexibility (intravenous or inhalation) greatly expands the scope of therapeutic options for the CF patient. Simple I.V. formulation could meet the needs to prevent exacerbations in CF patients who are already required to be hospitalized following an episode; however for chronic everyday use, an inhaled formulation would be more attractive to CF patients. Currently, nebulized liquid formulations can be cumbersome and time consuming considering an average CF patient is taking upwards of 9 medications for their condition at any given time. The future availability of dry powder formulations offer convenience but also have their limitations. These formulations require the patient to effectively self-administer the medication. Dry powder formulations will likely have labeling language excluding patients less than 6 years of age. A liquid formulation of Aerucin administered with an efficient nebulizer will offer the range of therapeutic options to maximize market penetration in the CF population. The current approach for use of TOBI in the CF patient recommends an alternating period of

antibiotic therapy for 28 days and then stops therapy for 28 days and resuming therapy for 28 days.

Aerucin™ for prevention of exacerbations and hospitalization in non-CF bronchiectasis and COPD.

Non-CF bronchiectasis and COPD are chronic lung disorders characterized by frequent lung infections and lung exacerbations (2-5 per year) leading to systemic antibiotic use and hospitalization. Each exacerbation increases the risk of antibiotic resistance and loss of lung function. Aerucin™ would be used in this setting to prevent exacerbation and hospitalization.

Preclinical Development

There is published in vitro data of Aerucin™ demonstrating effective phagocytic killing of both mucoid and non-mucoid isolates of Pa in vitro7. Furthermore, Aerucin demonstrated potent in vitro killing activity against a panel of recent P.aeruginosa clinical isolates, both mucoid and non-mucoid, with varying levels of antibiotic resistance to tobramycin and aztreonam (see figure).

Process Development

The stably transfected CHO cell line obtained from Dr. Pier’s lab exhibited a starting yield of 0.01 - 0.02 mg/mL or ~8 pg/cell/day when grown to exhaustion (~day 8) at a cell density limit of ~2x106 cells/mL in serum free F-12 media. Culture conditions were optimized by evaluating culture time, pH, feeding regime, seeding density, agitation speed and serum-free media. Antibody yields of 77 pg/cell/day at day 8 were observed with a cell density of up to 4.4 x106 cells/mL. This represents approximately a 10-fold antibody yield enhancement from the initial starting point of 8 pg/cell/day.

A second cell line expressing F429 mAb was developed to determine if the yields of F429 could be enhanced further. A mouse myeloma cell line NS0 (European Collection of Animal Cell Cultures, ECACC number 85110503) was used as the host cell line to express F429 light and heavy chain variable regions (VL and VH) genes in a single expression vector. NS0 was selected because it can be adapted to grow in protein-free medium and is one of the three most commonly used host cell lines for the production of human and humanized antibodies. A final clinical production cell line, called ‘2H2’, was selected for cell banking, and has been shown to have an initial mAb production yield of ~0.2g/L after 4-6 days without media optimization at 1-3L scale. Antibody produced from suspension cell cultures of these cells, followed by affinity column chromatography purification currently shows a production yield that can support phase 1 and 2 clinical studies.

Formulation Development

Aridis has a proprietary technology to produce room temperature stable powder containing Aerucin for direct inhalation using commercially available dry powder inhalers. However, while dry powder formulations bring several advantages in convenience and patient compliance, a simple refrigerated stable liquid formulation for systemic delivery will initially be developed. Formulations were tested for stability at 2-8°C and 37°C (accelerated condition) for six months to determine the most stable formulation. The data shown in the accompanying figure demonstrated that a simple histidine buffer (10 mM, pH 6.0) is sufficient to stabilize the antibody at 2-8° C.

Preclinical Safety Testing

Non-GLP Studies

Standard in vitro human tissue cross-reactivity studies were performed with tissue panel samples from three unrelated human donors. Preliminary results indicate that there was no cross reactivity to the FDA panel of 40 human tissues.

Preliminary pharmacokinetics study in rodents showed a 2-3 days lung residence time of antibodies delivered by intratracheal administration. Toxicology testing will include single and repeat dose inhalation studies performed with escalating doses in rodents.

GLP Toxicology Testing

Overview. GLP inhalation toxicology testing will be performed at contract laboratory and included in an IND with US FDA. Prior to initiation of tox studies the design and relevance of these studies will be discussed with FDA. There are certain circumstances in which tox studies may not be necessary with human mAbs. Nevertheless, our plans include the likelihood of both acute and repeat dose toxicology studies in two animal species (rodent and non-rodent).

Hospital’s Confidential Information shall also include all information disclosed by Hospital to Company in connection with the Patent Rights. Company’s Confidential Information shall also include all reports made pursuant to the License Agreement, including without limitation the development report appended to the license Agreement, and all royalty reports and related data; as well as all data disclosed in any audit or review performed by Hospital. Capitalized terms used in this Appendix that are not otherwise defined herein have the meanings ascribed in the License Agreement to which this Appendix is attached and made a part thereof.

2. Exclusions. “Confidential Information” under this Agreement shall not include any information that (i) is or becomes publicly available through no wrongful act of Recipient; was known by Recipient prior to disclosure by Discloser, as evidenced by tangible records; (ii) becomes known to Recipient after disclosure from a third party having an apparent bona fide right to disclose it; (iv) is independently developed or discovered by Recipient without use of Discloser’s Confidential Information, as evidenced by tangible records; or (v) is disclosed to another party by Discloser without restriction on further disclosure. The obligations of confidentiality and non-use set forth in this Agreement shall not apply with respect to any information that Recipient is required to disclose or produce pursuant to applicable law, court order or other valid legal process provided that Recipient promptly notifies Discloser prior to such required disclosure, discloses such information only to the extent so required and cooperates reasonably with Discloser’s efforts to contest or limit the scope of such disclosure.

3. Permitted Purpose. Recipient shall have the right to, and agrees that it will, use Discloser’s Confidential Information solely for the Purpose as described in the License Agreement, except as may be otherwise specified in a separate definitive written agreement negotiated and executed between the parties.

4. Restrictions. For the term of the License Agreement and a period of three (3) years thereafter (and indefinitely with respect to any individually identifiable health information disclosed by Hospital to Company, if any), each Recipient agrees that: (i) it will not use such Confidential Information for any purpose other than as specified herein, including without limitation for its own benefit or the benefit of any other person or entity; and (ii) it will use reasonable efforts (but no less than the efforts used to protect its own confidential and/or proprietary information of a similar nature) not to disclose such Confidential Information to any [ORIGINAL DOCUMENT ENDS HERE]
