covered by more than one of the Licensed Patent Rights. 


  

	 	6.8	 On sales of the Licensed Products by the Licensee to sublicensees or on sales made in other than
an arms-length transaction, the value of the Net Sales attributed under this Article 6 to this transaction shall be that which would have been received in an arms-length transaction, based on sales of like quantity and quality products on or

statement and request for payment, a royalty amount equivalent to these unreimbursed expenses paid during the previous calendar year(s); 


  

	 	(b)	 to pay these unreimbursed expenses directly to the law firm employed by the IC to handle these
functions. However, in this event, the IC and not the Licensee shall be the client of the law firm; or 


  

	 	(c)	 in limited circumstances, the Licensee may be given the right to assume responsibility for
the preparation, filing, prosecution, or maintenance of any patent application or patent included with the Licensed Patent Rights. In that event, the Licensee shall directly pay the attorneys or agents engaged to prepare, file,
prosecute, or maintain these patent applications or patents and shall provide the IC with copies of each invoice associated with these services as well as documentation that these invoices have been paid. 



 

	 	6.11	 The IC agrees, upon written request, to provide the Licensee with summaries of patent prosecution
invoices for which the IC has requested payment from the Licensee under Paragraphs 6.9 and 6.10. The Licensee agrees that all information provided by the IC related to patent prosecution costs shall be treated as

	 	8.1	 The Licensee agrees to keep accurate and correct records of the Licensed Products made, used,
sold, or imported and the Licensed Processes practiced under this Agreement appropriate to determine the amount of royalties due the IC. These records shall be retained for at least five (5) years following a given
reporting period and shall be available during normal business hours for inspection, at the expense of the IC, by an accountant or other designated auditor selected by the IC for the sole purpose of verifying reports and royalty
payments hereunder. The accountant or auditor shall only disclose to the IC information relating to the accuracy of reports and royalty payments made under this Agreement. If an inspection shows an underreporting or underpayment in excess of
five percent (5%) for any twelve (12) month period, then the Licensee shall reimburse the IC for the cost of the inspection at the time the Licensee pays the unreported royalties, including any additional royalties as
required by Paragraph 9.8. All royalty payments required under this Paragraph shall be due within sixty (60) days of the date the IC provides to the Licensee notice of the payment due.

commercialize under the Commercial Development Plan for each of the Licensed Fields of Use within sixty (60) days after December 31 of each calendar year. These progress reports shall include, but not be limited to: progress on
research and development, status of applications for regulatory approvals, manufacture and status of sublicensing, marketing, importing, and sales during the preceding calendar year, as well as, plans for the present calendar year. The IC also
encourages these reports to include information on any of the Licensee’s public service activities that relate to the Licensed Patent Rights. If reported progress differs from that projected in the Commercial Development Plan and
Benchmarks, the Licensee shall explain the reasons for these differences. In the annual report, the Licensee may propose amendments to the Commercial Development Plan, acceptance of which by the IC
may not be denied unreasonably. The Licensee agrees to provide any additional information reasonably required by the IC to evaluate the Licensee’s performance under this Agreement. The Licensee may amend the
Benchmarks at any time upon written approval by the IC. The IC shall not unreasonably withhold approval of any request of the Licensee to extend the time periods of this schedule if the request is supported by a
reasonable showing by the Licensee of diligence in its performance under the Commercial Development Plan and toward bringing the Licensed Products to the point of Practical Application as defined in 37 C.F.R.
§404.3(d). The Licensee shall amend the Commercial Development Plan and Benchmarks at the request of the IC to address any Licensed Fields of Use not specifically addressed in

	 	9.3	 The Licensee shall report to the IC the dates for achieving Benchmarks specified in
Appendix D and the First Commercial Sale in each country in the Licensed Territory within thirty (30) days of such occurrences. 


  

	 	9.4	 The Licensee shall submit to the IC, within sixty (60) days after each calendar half-year
ending June 30 and December 31, a royalty report, as described in the example in Appendix F, setting forth for the preceding half-year period the amount of the Licensed Products sold or Licensed Processes practiced by or on
behalf of the Licensee in each country within the Licensed Territory, the Net Sales, and the amount of royalty accordingly due. With each royalty report, the Licensee shall submit payment of earned royalties due. If no
earned royalties are due to the IC for any reporting period, the written report shall so state. The royalty report shall be certified as correct by an authorized officer of the Licensee and shall include a detailed listing of all deductions
made under Paragraph 2.13 to determine Net Sales made under Article 6 to determine royalties due. The royalty report shall also identify the site of manufacture for the Licensed Product(s) sold in the United States.



  

	 	9.5	 The Licensee agrees to forward semi-annually to the IC a copy of these reports received by the
Licensee from its sublicensees during the preceding half-year period as shall be pertinent to a royalty accounting to the IC by the Licensee for activities under the sublicense. 



 

	 	9.6	 Royalties due under Article 6 shall be paid in U.S. dollars and payment options are listed in Appendix G. For
conversion of foreign currency to U.S. dollars, the conversion rate shall be the New York foreign exchange rate quoted in The Wall Street Journal on the day that the payment is due. Any loss of exchange, value, taxes, or other
expenses incurred in the transfer or conversion to U.S. dollars shall be paid entirely by the Licensee. The royalty report required by Paragraph 9.4 shall be mailed to the IC at its address for Agreement Notices indicated on the
Signature Page. 


  

	 	9.7	 The Licensee shall be solely responsible for determining if any tax on royalty income is owed outside
the United States and shall pay the tax and be responsible for all filings with appropriate agencies of foreign governments. 


  

	 	9.8	 Additional royalties may be assessed by the IC on any payment that is more than ninety (90) days
overdue at the rate of one percent (1%) per month. This one percent (1%) per month rate may be applied retroactively from the original due date until the date of receipt by the IC of the overdue payment and additional royalties. The
payment of any additional royalties shall not prevent the IC from exercising any other rights it may have as a consequence of the lateness of any payment. 



 

	 	9.9	 All plans and reports required by this Article 9 and marked “confidential” by the Licensee
shall, to the extent permitted by law, be treated by the IC as commercial and financial information obtained from a person and as privileged and confidential, and any proposed disclosure of these records by the IC under the Freedom of
Information Act (FOIA), 5 U.S.C. §552 shall be subject to the predisclosure notification requirements of 45 C.F.R. §5.65(d).

	 	10.2	 Upon the First Commercial Sale, until the expiration or termination of this Agreement, the
Licensee shall use its reasonable commercial efforts to make the Licensed Products and the Licensed Processes reasonably accessible to the United States public. 



 

	 	10.3	 The Licensee agrees, after its First Commercial Sale, to make reasonable quantities of the
Licensed Products or materials produced through the use of the Licensed Processes available to patient assistance programs. 


  

	 	10.4	 The Licensee agrees, after its First Commercial Sale and as part of its marketing and product

	11.	 INFRINGEMENT AND PATENT ENFORCEMENT 



 

	 	11.1	 The IC and the Licensee agree to notify each other promptly of each infringement or
possible infringement of the Licensed Patent Rights, as well as, any facts which may affect the validity, scope, or enforceability of the Licensed Patent Rights of which either party becomes aware. 



 

	 	11.2	 Pursuant to this Agreement and the provisions of 35 U.S.C. Chapter 29, the Licensee may:

	 	(b)	 in any suit, enjoin infringement and collect for its use, damages, profits, and awards of whatever nature
recoverable for the infringement; or 


  

	 	(c)	 settle any claim or suit for infringement of the Licensed Patent Rights provided, however, that the
IC and appropriate Government authorities shall have the first right to take such actions; and 


  

	 	(d)	 if the Licensee desires to initiate a suit for patent infringement, the Licensee shall notify the

action to compel the Government either to initiate or to join in any suit for patent infringement. The Licensee may request the Government to initiate or join in any
suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any suit, the Licensee shall reimburse the Government for any costs, expenses, or fees which the Government
incurs as a result of the motion or other action, including all costs incurred by the Government in opposing the motion or other action. In all cases, the Licensee agrees to keep the IC reasonably apprised of the status and
progress of any litigation. Before the Licensee commences an infringement action, the Licensee shall notify the IC and give careful consideration to the views of the IC and to any potential effects of the litigation on
the public health in deciding whether to bring suit. 

  

	 	11.3	 In the event that a declaratory judgment action alleging invalidity or
non-infringement of any of the Licensed Patent Rights shall be brought against the Licensee or raised by way of counterclaim or affirmative defense in an infringement suit brought by the
Licensee under Paragraph 11.2, pursuant to this Agreement and the provisions of 35 U.S.C. Chanter 29 or other statutes, the Licensee may: 



 

	 	(a)	 defend the suit in its own name, at its own expense, and on its own behalf for presumably valid claims in the
Licensed Patent Rights; 


  

	 	(b)	 in any suit, ultimately to enjoin infringement and to collect for its use, damages, profits, and awards of
whatever nature recoverable for the infringement; and 


  

	 	(c)	 settle any claim or suit for declaratory judgment involving the Licensed Patent Rights-provided,
however, that the IC and appropriate Government authorities shall have the first right to take these actions and shall have a continuing right to intervene in the suit; and 



 

	 	(d)	 if the IC does not notify the Licensee of its intent to respond to the legal action within a
reasonable time, the Licensee shall be free to do so. The Licensee shall take no action to compel the Government either to initiate or to join in any declaratory judgment action. The Licensee may request the
Government to initiate or to join any suit if necessary to avoid dismissal of the suit. Should the Government be made a party to any suit by motion or any other action of the Licensee, the Licensee shall reimburse the
Government for any costs, expenses, or fees, which the Government incurs as a result of the motion or other action. If the Licensee elects not to defend against the declaratory judgment action, the IC, at its option, may
do so at its own expense. In all cases, the Licensee agrees to keep the IC reasonably apprised of the status and progress of any litigation. Before the Licensee commences an infringement action, the Licensee shall notify
the IC and give careful consideration to the views of the IC and to any potential effects of the litigation on the public health in deciding whether to bring suit. 



 

	 	11.4	 In any action under Paragraphs 11.2 or 11.3 the expenses including costs, fees, attorney fees, and
disbursements, shall be paid by the Licensee. The value of any recovery made by the Licensee through court judgment or settlement shall be treated as Net Sales and subject to earned royalties.

materials by the Licensee, or other products or processes developed in connection with or arising out of the Licensed Patent Rights.

pursue outstanding royalties owed through procedures provided by the Federal Debt Collection Act. 

  

	 	13.3	 In the event that the Licensee becomes insolvent, files a petition in bankruptcy, has such a petition

waived. 


  

	 	13.6	 In making the determination referenced in Paragraph 13.5, the IC shall take into account the normal

	 	13.7	 When the public health and safety so require, and after written notice to the Licensee providing the
Licensee a sixty (60) day opportunity to respond, the IC shall have the right to require the Licensee to grant sublicenses to responsible applicants, on reasonable terms, in any Licensed Fields of Use under the
Licensed Patent Rights, unless the Licensee can reasonably demonstrate that the granting of the sublicense would not materially increase the availability to the public of the subject matter of the Licensed Patent Rights. The

	 	13.8	 The IC reserves the right according to 35 U.S.C. §209(d)(3) to terminate or

 APPENDIX E — COMMERCIAL DEVELOPMENT PLAN 

Introduction and Overview - Atopic Dermatitis 

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by pruritus (itching) and xerosis (dry skin). AD pruritis can be severe, leading to
changes in the skin, including thickening of the skin (lichenification), breakdown of the skin barrier and scarring. Xerosis in atopic dermatitis results from the disruption of the epidermal integrity and further dysfunction of the skin barrier.
Atopic dermatitis lesions present most commonly on the scalp, face and extremities and can vary depending on the degree of inflammation and secondary infection. Both environmental and genetic factors appear to contribute to the pathogenesis of
atopic dermatitis with hyper-reactive basophils and mast cells resulting in increased histamine and leukotriene production and elevated serum IgE. Bacterial infections are also common in atopic dermatitis patients and the significant majority of AD
patients are colonized with toxin producing S. aureus. S. auerus toxins and superantigen presentation are believed to contribute to the pathogenesis of AD. 

According to the American Academy of Dermatology, worldwide, between 10% and 20% of children suffer from atopic dermatitis (AD) and approximately 1% to 3% of
adults experience AD. Atopic dermatitis most commonly occurs before the 5th birthday and approximately 50% of children with AD will experience a recurrence in adulthood. 

Current Treatment Algorithm 
 The treatment of atopic
dermatitis focuses on addressing the associated pruritus, xerosis, inflammation and infection. For mild breakthrough AD, low to moderate strength topical corticosteroids are used along with antihistimines as needed to address itching. For mild to
moderate AD, increased intensity topical corticosteroids are employed along with regular use of antihistimines. If symptoms do not improve, phototherapy and systemic therapies can be administered. According to the AAD guidelines for atopic
dermatitis, systemic therapies can include cyclosporine, methotrexate, mycophenolate mofetil, and azathioprine as well as leukotriene inhibitors and oral calcineurin inhibitors. The management of AD with systemic corticosteroids is recommended to be
avoided because of adverse side effects and unfavorable risk-benefit of systemic corticosteroids for atopic dermatitis. Treatment of S. aureus infections, which contributes to the AD pathogenesis, can be treated with antibiotics and bleach baths.

 More recently, Regeneron and Sanofi’s Dupixent (dupilumab), an antibody targeting the IL-4 receptor alpha, was approved by FDA for the treatment of adult patients with moderate to severe atopic dermatitis whose disease is not adequately controlled with topical prescription therapies or when those
therapies are not advisable. Dupixent can be used with or without topical corticosteroids.

 Microbiome transplantation for treatment of patients with atopic dermatitis 

Gram-negative microbiota differ between healthy controls and patients with AD, Myles et al. identified that the predominant gram-negative species identified
on healthy volunteers as Roseomonas mucosa. Overgrowth and infection with S. aureus are both contributors to the immune imbalance and poor barrier function in AD. Treatment with antibiotics can reduce S. aureus burdens and improve symptoms
but does not normalize the underlying pathology. Myles and Datta found that supernatants from healthy volunteer, gram negative culturable bacteria inhibited S. aureus by nearly 50% versus the media control and that select strains of the
gram-negative bacteria R. mucosa from healthy controls transplanted onto the skin influenced S. aureus growth, transepidermal water loss associated with AD and influenced certain parameters of innate immune activation. The authors concluded that a
live biotherapeutic approach may hold promise for treatment of patients with atopic dermatitis and have initiated clinical studies testing the safety and efficacy of topically administered R. mucosa for the treatment of AD.

Process Development and Manufacturing Detailed Overview 

Process development, formulation, manufacturing and fill/finish of the drug product will conducted in accordance with the USP and FDA guidance. 

In brief, process development of the drug product will include selection and testing to determine optimal vialing format, formulation development of the spray
nozzle applicator and development of validation of the product quality and performance parameters 
 Testing will be conducted to assess bacterial
suspension in solution in comparison to lyophilization, required reconstitution parameters, stability and bacterial proliferation parameters, cell viability/stability, spray dispersion and consistency of bacterial delivery, aerosolizing parameter
definition and testing and contaminant microorganism characterization. 
 Background on manufacturing and formulation guidance for topical drug products

 FDA has issued guidance for the current good manufacturing practice (CGMP) of topical drug product production. 

The key focus for the CGMP of topical drug products focuses on the active ingredient uniformity, physical characteristics and chemical and microbial purity.
FDA examination of manufacturing and control data and correspondence is to be complete early in the process and the specific and complete control data contained in the application is to be compared to the clinical batches and the production
validation batches. In the case of the live bacterial topical biotherapeutic assurance of uniform potency and dispersion is required. In this case both the bacterial viability/stability in the final drug product containment will need to be
assessed. If the final drug product is in solution, the parameters of the reproducibility of the bacterial delivery (spray coating) are to be defined. Production temperature and sterility is a key to confirm that no objectionable
microorganism

are present. SOPs for cleaning validation will be established to preclude contamination of current and future batches. FDA emphasizes that it is therefore vital that manufacturers assess the
health hazard of all organisms isolated from the drug product. Undesirable microbaterial growth factors which influence microbial growth include flow rates, temperature, surface area of resin beds and the microbial quality of the feed water.

 Microbiological Specifications and Test Methods for Topical Drug Products 

During inspections it is important to audit the microbiological specifications and microbial test methods used for each topical product to assure that they are
consistent with any described in the relevant application. FDA has commented that it is often helpful for the inspection to include an FDA microbiologist. 

Generally, product specifications should cover the total number of organisms permitted, as well as specific organisms that must not be present. These
specifications must be based on use of specified sampling and analytical procedures. Where appropriate, the specifications should describe action levels where additional sampling and/or speciation of organisms is necessary. 

Manufacturers must demonstrate that the test methods and specifications are appropriate for their intended purpose. Where possible, methods should be utilized
that isolate and identify organisms that may present a hazard to the user under the intended use. 
 In assessing the significance of microbial
contamination of a topical product, both the identification of the isolated organisms and the number of organisms found are significant. For example, the presence of a high number of organisms may indicate that the manufacturing process, component
quality, and/or container integrity may be deficient. Although high numbers of non-pathogenic organisms may not pose a health hazard, they may affect product efficacy and/or physical/chemical stability.
Inconsistent batch to batch microbial levels may indicate some process or control failure in the batch. The batch release evaluation should extend to both organism identification and numbers and, if limits are exceeded, there should be an
investigation into the cause. 
 In addition, “The Topical and Transdermal Drug Products” monograph from the topical/transdermal ad hoc advisory
panel for the USP performance tests of topical and transdermal dosage forms defines the parameters for drug device combinations that have local action at or on the surface of the skin. 

The USP monograph defines two categories of tests: product quality tests and product performance tests, that are to be performed with topically administered
drug products to provide assurances of batch-to-batch quality, reproducibility, reliability, and performance. Product quality tests are performed to assess attributes
such as assay, identification, content uniformity, pH, microbial limits, and minimum fill and are part of the compendial monograph. Product performance tests are conducted to assess drug release from the finished dosage form.

 Using the recently approved Dupixent systemic therapy as a benchmark for clinical development in atopic
dermatitis, approval may require 3 clinical trials in approximately 1,300 patients examining therapy vs placebo and therapy on top of topical corticosteroids. Endpoints may include investigator global assessment of 0 or 1 (clear or almost clear) and
greater than 2 point improvement from baseline, EASI-75 (75% or greater improvement from baseline of eczema and severity index) , EASI-90 (90% improvement from baseline
of eczema and severity index) and a greater than 4 point improvement in the peak pruritis scoring.

 Commercialization 

According to the National Eczema Association, 31.6 million people in the US suffer with atopic dermatitis, (17.8 million with moderate to severe
atopic dermatitis). The prevalence of childhood eczema/atopic dermatitis in the US is 10.7% overall. Approximately one out of every three children with eczema/atopic dermatitis has moderate to severe disease. A recent study found that the
prevalence of eczema in adults could be as high as 10.2%. Three percent of US adults have moderate to severe eczema/atopic dermatitis requiring systemic therapy. These numbers are much higher than for psoriasis, a disease that now has many
good-targeted treatments for moderate to severe patients. There are still very large unmet needs for the treatment of patients with eczema / atopic dermatitis that could be address with a topical live biotherapeutic approach. 

The current pricing for the recently approved systemic antibody therapy Dupixent is $37,000 per year. 

The final pricing and market opportunity for the topical live biotherapeutic will be a function of the detailed efficacy and safety data obtained from the
phase 3 trial; however, we believe that a topical live biotherapeutic could offer meaningful benefit to atopic dermatitis patients at a fraction of the cost and with lower risk (topical vs systemic).
