CLIN 0001 Overview

Avita’s initial primary objective with the proposed effort is to secure FDA approval for the ReCell device. In order to accomplish this we need (1) a documented design (with documentation and supporting testing ¬e.g. biocompatibility- done to FDA standards rather than ISO standards), for which the work is done in WBS 2.1.2, 2,1.3, and 2.1.4; (2) an FDA-compliant quality system and documentation of GMP manufacturing: WBS 6.1; and (3) Pivotal Clinical Data: WBS 3.1.

The above-mentioned work is delivered to FDA via PMA modules 1, 2 and 3, respectively (WBS 4.2.2). The PMA modules will require organizing and assembling reports into a standardized format, setting context and drawing overall conclusions. In addition to submission of the PMA modules, Avita will also draft (and get FDA-approval of) a Conditions of Approval study protocol (WBS 3.3.1.1, 4.2.2.4.2), and pass through a panel (of experts) review (WBS 4.2.2.5). Avita will need favorable reviews of the PMA modules, CoA protocol approval, and panel review to get the product approved.

Concurrent with the FDA approval process, there is an Emergency Use pathway, activated in the event of a mass casualty, which would enable FDA to authorize use of an investigational (unapproved) product for life-saving measures. There is “pre-emergency” work that can be done to facilitate a future potential Authorization. (WBS 4.1)

Once there is confidence in EUA status or there is PMA approval, base procurement (WBS 7.1.1) is triggered.

There are several other items that are part of the program in order to ensure success in stockpiling, distributing, and using ReCell during an emergency event:

1. Training of medics for use of ReCell in mass casualty events (WBS 2.1.1).

2. Increased shelf-life, with a target of up to 4 years (as supported by stability testing) (WBS 2.3)

3. VMI planning/implementation (WBS 7.2, 7.3, 7.4)

4. Optimize product packaging more for palletized storage and VMI, (WBS 5)

5. Qualifying second sources for key components and for product final assembly (i.e. alternative/supplementary sources for enzyme and a supplement/alternative to Parker) (WBS 6.2.2).

CLIN 0001A Overview

The objectives of CLIN 0001a are to facilitate the overarching objective of preparedness for effective treatment of burn injuries secondary to detonation of a nuclear device. In addition to ensuring FDA approval of the ReCell device, the work put forward in this SOW further bolsters efforts for development of familiarity and acceptance of the autograft-sparing product within U.S. Burn Centers by expanding Compassionate Use (WBS 2.1.5), extending Continued Access (WBS 2.1.6), incorporating Reimbursement training (WBS 2.1.6) and Modeling the Economic Benefits of Medical Countermeasures (WBS 2.1.8).

Additionally, this SOW includes scope to ensure successful navigation of the PMA Pathway by adding a BIMO Mock Audit and adding in-house technical and regulatory expertise for overall support to de-risk the program (4.3.1)

2.1.5 Title: Compassionate Use IDE 15945

Objective/Description of Work: Avita’s Compassionate Use IDE provides a mechanism for surgeon access to ReCell as an investigational device, for patients presenting with life-threatening injuries for which there is insufficient donor skin for conventional autograft treatment. Requests, along with a letter of support, are evaluated for suitability and patients are approved by Avita on a case by case basis. Surgeons may request Compassionate Use regardless of their prior experience with ReCell and independent from their site’s participation in IDE 13053 for the study of burns). The Compassionate Use IDE provides for further experience in the use of ReCell, toward fulfilment of BARDA’s objective of familiarity/acceptance in US burn centers. Avita personnel travel to support these surgeries, and a 3`d-party CRO and an independent consultant are contracted to perform clinical monitoring for compliance with Good Clinical Practice. In-house regulatory personnel will draft associated regulatory submissions.

Milestones:

2.1.6 Title: Continued Access IDE 13053

Objective/Description of Work: FDA may allow continued enrollment of subjects after the controlled clinical trial under an IDE has been completed in order to allow access to the investigational medical device while the marketing application is being prepared by the sponsor or reviewed by FDA. Under this policy, a sponsor may propose to conduct an “extended” clinical trial if: 1) there is a public health need for the device and 2) there is preliminary evidence that the device is likely to be effective and no significant safety concerns have been identified for the proposed indication. Avita will submit CTP001-7 to the FDA to allow Continued Access of ReCell at up to 15 clinical sites for treatment of up to an additional 100 patients. As with Compassionate Use, this positions the US burn centers to be more effective in the event of a mass casualty. Onsite training of burn centers will be required, and a 3^rd-party CRO will be contracted for clinical project management, clinical data management and clinical monitoring, for compliance with IDE requirements.

2.1.8 Title: Modeling the Economic Benefits of Medical Countermeasures

Objective/Description of Work: Avita will work with a Subject Matter expert to develop a generic model for cost and economic impact in burn care with introduction of ReCell technology as a candidate for evaluation, both at the single-center level, and a multi-center (commercial) use. The model (aka tool) will allow for evaluation of cost impact on burn care from use of specific products as well as broader economic impact. The tool is expected to be self-standing and include access to other required information such as databases necessary for full functionality and use of the software. Other features of the model will include:

a. A comprehensive review of parameters which influence the integrated cost impact on burn care (and broader economic impact) both directly or indirectly would be identified and evaluated. Such parameters may include but are not limited to impact of resources (surgical and non-surgical) personnel time, material resources as well tangible changes to the clinical outcomes (example, length of hospital stay or ICU days). Impact of product launch pricing models and potential market share over time may also be included in the tool.

b. The tool will be designed to predict costs and benefits associated with the care of burn patients based on (i) specifiable characteristics of a hypothetical group of patients (e.g. in terms of burn severity, number of patients, etc) and (ii) modeled changes to fundamental cost drivers associated with particular changes in practice as a result of introduction of the new product and associated downstream impact. As such, the financial and economic impact of introduction of medical countermeasures, alone and in combination, may become predictable.

Avita Medical Statement of Work, 09/18/2017 HHS0100201500028c Page 10

c. Avita will test the tool with available data and assumptions and iteratively develop in consultation with the experts to refine the model using ReCell data as well as to ensure the generic nature of the cost and economic Impact tool.

d. For this effort it is recognized that definitive burn care is typically provided over time and that care treatments/procedures change as burn etiology evolves. This has allowed for identification of distinct treatment areas within the definitive care continuum. New products (such as Avita’s ReCell) directed at such treatment targets are expected to have an impact on the cost effectiveness of burn care, which represents the over-arching scope of this effort.

e. For the sake of comprehensive analysis under this effort, an exhaustive list of parameters (preferably ranked) shall be identified and qualified to be measurable within the following treatment targets in the continuum of definitive care: (1) debridement, (2) application of skin substitutes (which eliminate autografting), (3) autograft sparing technology, and (4) adjuncts to enhance/accelerate healing.

f. The overall capability of the tool is to capture the key parameters across this continuum wherein impact of any new products altering these key parameters within a treatment area, objectively demonstrates a clear, measurable value proposition (or a lack thereof) in the overall cost effectiveness and other attributes. The tool would also feature an ability to be customized either by turning on or off the key parameters or add a user chosen parameter, based on relevance to target area.

g. Based upon a competitive selection process between three potential SME’s, [**] is the primary candidate for this project. A designated panel of experts should be accessible.

2.1.8.1 Title: Kick-off Meeting & Project Management

Objective/Description of Work: A Kick-off meeting will be conducted to:

• Introduce the project team members

• Discuss KOL selection process;

• Review and confirm the goals of the project;

• Finalize the approach to the project phases; and

• Review anticipated project deliverables, milestones and timelines (Gantt chart).

Milestones:

2.1.8.1 Complete Kick-off Meeting

Deliverable:

2.1.8.1 MS PowerPoint presentation outlining understanding of goals, objectives, anticipated approach, and project deliverables, milestones, and timeline.

2.1.8.2 Title: Targeted Literature Search

Objective/Description of Work: Develop literature search strategy and obtain agreement with BARDA. Perform literature search and report on results.

Milestones:

2.1.8.2 Complete Literature Search

Avita Medical Statement of Work, 09/18/2017 HHS0100201500028c Page 11

Deliverable:

2.1.8.2 Draft and final literature review search strategy in MS Word.

2.1.8.3 Title: Focusing goals

Objective/Description of Work: Compile a preliminary burn care model structure and identify any key points that may require discussion and agreement between project participants. Develop a discussion deck (in MS PPT) that outlines options for the model framework, including a detailed proposed structure. The deck will be used to facilitate an interactive discussion with BARDA.

Milestones:

2.1.8.3 Complete Briefing which defines focus of goals

Deliverable:

2.1.8.3 A brief MS PowerPoint presentation outlining options for the model framework and structure to facilitate discussion; appended summary of action items.

2.1.8.4 Title: Model Storyboard

Objective/Description of Work: Develop a Model Storyboard, which is a detailed plan for the model, intended to provide an opportunity for discussion and agreement with BARDA, prior to programming. This storyboard will include the model structure to facilitate cost-effectiveness and budget impact assessments, detailed parameter types (including all clinical inputs and costs), with referenced default values for all variables, as well as model user-functionality and model outputs.

Although this model will be developed to have a generic structure, the storyboard and model development will be performed to permit evaluation of Avita’s ReCell technology. One primary comparator (e.g. a standard autograft procedure) will serve as the base case for the cost-effectiveness evaluation, and will focus the storyboard accordingly with detailed input values around ReCell and the base case comparator. The model will be developed to include up to three (3) dummy comparators to permit exploration of additional interventions at points along the burn care pathway, but data specific to these hypothetical interventions will not be included in the storyboard or analyses. Because the US model may be used in discussions with different types of stakeholders, it is anticipated that the storyboard will include information to inform different perspectives, including hospital perspective, payer perspective, and at BARDA’s option, societal perspective. Differences between these may include time horizon (shorter term for hospital perspective) and cost inputs. It is assumed that budget impact calculations will rely on the same underlying structure and inputs as are used for the cost- effectiveness model, and thus gain efficiencies between the two analysis types. However, pricing predictions, market uptake assumptions and market share distribution will be required from marketing research. Any additional detailed clinical and cost input values not available from other sources may be solicited from KOLs (e.g. likely resource use assumptions); based on discussion with KOLs, however, a survey or database analysis Optional Task may be desired to obtain the best possible data.

Avita Medical Statement of Work, 09/18/2017 HHS0100201500028c Page 12

After presentation of the storyboard to BARDA, comments received during this meeting and any additional consolidated comments received in the following week will be incorporated into a storyboard revision. Input from all internal stakeholders at this phase will ensure the model contains the appropriate elements and addresses key considerations. This revision will serve as the platform for the first KOL engagement.

Milestones:

2.1.8.4 Completion of Model Storyboard

Deliverable:

2.1.8.4 Draft and revised model storyboards (MS PowerPoint).

2.1.8.5 Title: KOL Engagement

Objective/Description of Work: Engage three KOLs for the following:

• One hour each for a meeting to collect feedback on the proposed model storyboard;

• One additional hour each to help fill any key model data gaps (e.g. providing resource use assumptions);

• A two-hour advisory panel (joint meeting) for a discussion of the preliminary model and results. (At Avita’s option, this may be redefined as a half-day advisory board with KOLs and all project participants. Please see Optional Tasks.)

Engage with the KOLs via teleconference, utilizing presentation materials generated during other project tasks, including the storyboard and preliminary model results presentation. Provide a short written summary of meeting minutes and implications for analysis following ach discussion. Following one round of review, the summary of feedback (meeting minutes) document will be considered final, and details will be incorporated into a final version of the storyboard.

The budget assumes [**] US-based KOLs. Payment of honoraria will be contracted in accordance with Avita governance procedures. Any fees paid by will be considered as pass-through costs to BARDA and will be clearly reported and documented.

Milestones:

2.1.8.5 Complete Recruitment of KOL’s

Deliverable:

2.1.8.5 KOL recruitment and management (for [**] KOLs), draft and final KOL summary feedback (Word) for all KOL meetings, final storyboard (MS PowerPoint). KOL’s to be approved by BARDA

2.1.8.6 Title: Preliminary Model Programming and Results

Objective/Description of Work: Initiate programming the model for use on a PC platform with MS Excel 2013. Populate the model with parameter estimates, and use the model to generate preliminary estimates of the cost- effectiveness of using ReCell technology vs a chosen appropriate comparator available perspectives (e.g. hospital, payer, and

Avita Medical Statement of Work, 09/18/2017 HHS0100201500028c Page 13

(optional) US society), and of the budget impact of adding ReCell to the available burn care therapies. Include up to [**] dummy comparators into the model (one for each phase of the burn care pathway) to permit evaluation of the impact of other therapeutic options. Model programming will also include a univariate sensitivity analysis function to identify the most sensitive parameters in the model, displayed as a tornado diagram for convenient interpretation and reporting.

At this stage, Avita will outline preliminary model results, and will present the draft results to BARDA to obtain internal feedback, and also deliver the preliminary model to ensure transparency.

After collecting initial feedback from BARDA, engage the [**] KOLs in a single 2-hour meeting for collective review and validation.

Milestones:

2.1.8.6 Complete Preliminary Model

Deliverable:

2.1.8.6 Preliminary model (MS Excel 2013 file for PC) and a presentation of preliminary findings in a MS PowerPoint slide deck to be shared with Avita via WebEx or during an in-person meeting.

Overview

Avita has defined three option periods covering the Conditions of Approval (CoA) study after FDA approval of the ReCell Device (CLIN 0003), a Pediatric study to expand the indications for ReCell for a broader pediatric demographic, if necessary, for ReCell (CLIN 0004), and for the procurement of additional ReCell devices beyond the initial acquisition (CLIN0005). Note: Updated SOW(s) will be provided to BARDA based on FDA feedback to support the execution of each CLIN. The accompanying budget(s) will also be updated to align with the revised SOW(s).

The purpose of the CoA, CLIN 0003, is to provide longer-term evaluation of the ReCell device after FDA approval, in order to track and confirm that any post-market commitments are addressed by Avita.

The purpose of the Pediatric Study, CLIN 0004, is to expand the approved range of patients for ReCell, specifically for pediatric patients, beyond those originally approved during the PMA process. The specific study design and objectives will be based on the PMA approval outcomes as well as consultation with BARDA, and will be intended to expand the range of patients able to be treated by ReCell.

Surge acquisition, CLIN 0005, will support additional acquisition of ReCell devices by BARDA, CDC, or other stakeholders.

2.2 Title Update the Burn Care Pathway Model

Objective/Description of Work: Goals of the research: To add to the underlying calculations, data, interface and documentation of the existing Burn Care Pathway Model.

2.2.1 Title Update the Burn Care Pathway Model with Pediatric Data

Objective/Description of Work: Although the existing Burn Care Model includes pediatric patients as well as indeterminate deep partial or superficial partial thickness burns, assumptions are currently in place regarding burn management and relevant inputs. In particular, accuracy of diagnosis impacts whether a partial thickness burn is treated like a full thickness burn, or whether the burn is assumed to heal without grafting. Additionally, although resource use for children reflects smaller body surface area, other costs are assumed equivalent between children and adults due to lack of pediatric-specific expert insight. As Avita is currently planning two clinical trials to support the use of ReCell in pediatric patients with partial thickness burns, additional detail can be added to the model following completion of these protocols. All optional tasks will require review and discussion between BARDA and Avita for need and scope, prior to submission of a COA request to proceed being initiated.

QI will conduct one round of narrative revisions requested by journal reviewers and will resubmit once, if necessary. Substantial revisions requested by journal reviewers, including revisions that require additional data analysis, or a mutual decision to resubmit the manuscript to a separate journal, may require a scope amendment for this task. 01 adheres to authorship guidelines as established by ICMJE (www.icmje.org/ethicalalauthor.html).

2.2.2 Title Optional Tasks to Update the Burn Care Pathway Model with Outpatient Data

Objective/Description of Work: Optional work is proposed to add to or amend the underlying calculations, interface and documentation of the existing Burn Care Model, to support discussions regarding outpatient use of ReCell. All optional tasks will require review and discussion between BARDA and Avita for need and scope, prior to submission of a COA request to proceed being initiated.

2.2.2.1 Title Option 1: Burn Care Model Expansion: Outpatients

Objective/Description of Work: One possible use for ReCell technology is in an outpatient setting, to alleviate the need for inpatient beds or time, which would be highly valuable to relieve the bottlenecks in the event of mass casualty. While the burn care model has been established to make use of trial data and inpatient resource use and costing assumptions, the outpatient setting differs significantly, with changes needed to accommodate:

• Defining the types of burns that could be managed in an outpatient setting (including primary outpatient intervention as well as post-discharge outpatient follow-up care);

• Resource use specific to these burn types and outpatient facilities;

• Unit costs specific to outpatient resource use.
