Intended Use

Oncospace is used to configure and review radiotherapy treatment plans for a patient with malignant or benign disease in the prostate, head, and neck regions. It allows for set up of radiotherapy treatment protocols, association of a potential treatment plan with the protocol(s), submission of a dose prescription and achievable dosimetric goals to a treatment planning system, and review of the treatment plan. It is intended for use by qualified, trained radiation therapy professionals (such as medical physicists, oncologists, and dosimetrists). This device is for prescription use by order of a physician.

Device Story

Oncospace is a software-only tool for radiation therapy professionals (oncologists, physicists, dosimetrists) to assist in treatment planning. It ingests patient-specific anatomical geometry and treatment protocols; uses locked machine learning models to predict dosimetric goals for organs at risk (OARs); and provides a user interface for plan evaluation. The software does not replace a treatment planning system (TPS) but integrates with it by supplying prescriptions and objectives to automate plan optimization. It does not interface with treatment machines or record-and-verify systems. By predicting achievable OAR doses, it helps clinicians optimize plans, potentially reducing the number of iterations required to reach a clinically acceptable plan. It is used in clinical settings (hospitals/offices) to improve planning efficiency and quality.

Clinical Evidence

Retrospective validation trial using 13 prostate and 19 head & neck treatment plans. Compared Oncospace-assisted planning against traditional clinical workflows. Primary endpoints: non-inferiority of mean OAR dose sparing (margin 10 Gy) and target coverage. Results: Oncospace demonstrated non-inferiority (mean OAR dose difference < 5 Gy for prostate, < 8 Gy for head & neck). No statistically significant difference in target coverage. Average number of optimization iterations reduced by 77%.

Technological Characteristics

Software-only medical device; client-server architecture (clinic-provided clients, cloud Windows servers). Connectivity via DICOM-RT. Features locked machine learning algorithms for dosimetric prediction. No hardware components; no direct interface with radiation delivery devices.

Indications for Use

Indicated for patients with malignant or benign disease in the prostate, head, and neck regions requiring radiotherapy treatment planning. Intended for use by qualified radiation therapy professionals (medical physicists, oncologists, dosimetrists) under physician prescription.

PREDICATE DEVICE Oncospace, K202284 This predicate device has not been the subject of a recall. #### IV. DEVICE DESCRIPTION The Oncospace software supports radiation oncologists and medical dosimetrists during radiotherapy treatment planning. The software includes locked machine learning algorithms. During treatment planning, the Oncospace software works in conjunction with, and does not replace, a treatment planning system (TPS). The Oncospace software is intended to augment the treatment planning process by: - . allowing the radiation oncologist to select and customize a treatment planning protocol that includes dose prescription (number of fractions, dose normalization), a delivery method (beam type and geometry), and protocol-based dosimetric goals/objectives for treatment targets, and organs at risk (OAR); {4}------------------------------------------------ Image /page/4/Picture/2 description: The image contains a logo for OncoSpace. The logo features a stylized letter "C" made up of two different colored arcs, teal and yellow. To the right of the "C" is the word "ONCOSPACE" in a light gray color. The logo is set against a light gray background. - predicting dosimetric goals/objectives for OARs based on patient-specific anatomical geometry; ● - . automating the initiation of plan optimization on a TPS by supplying the dose prescription, delivery method, protocol-based target objectives, and predicted OAR objectives; - providing a user interface for plan evaluation against protocol-based and predicted goals. Diagnosis and treatment decisions occur prior to treatment planning and do not involve Oncospace. Decisions involving Oncospace are restricted to setting of dosimetric goals for use during plan optimization and plan evaluation. Human judgement continues to be applied in accepting these goals and updating them as necessary during the iterative beam optimization process. Human judgement is also still applied as in standard practice during plan quality assessment; the protocol-based OAR goals as the primary means of plan assessment, with the role of the predicted goals being to provide additional information as to whether dose to an OAR may be able to be further lowered. When Oncospace is used in conjunction with a TPS, the user retains full control of the TPS, including finalization of the treatment plan created for the patient. Oncospace also does not interface with the treatment machines. The risk to patient safety is lower than a TPS since it only informs the treatment plan, does not allow region of interest editing, does not make treatment decisions, and does not interface directly with the treatment machine or any record and verify system. Oncospace's OAR dose prediction approach, and the use of predictions in end-to-end treatment planning workflow, has been tested for use with a variety of cancer treatment plans. These included a wide range of target and OAR geometries, prescriptions and boost strategies (sequential and simultaneous delivery). Validity has thus been demonstrated for the range of prediction model input features encountered in the test cases. This range is representative of the diversity of the same feature types (describing target-OAR proximity, target and OAR shapes, sizes, etc.) encountered across all cancer sites. Given that the same feature types will be used in OAR dose prediction models trained for all sites, the modeling approach validated here is not cancer site specific, but rather is designed to predict OAR DVHs based on impactful features common to all sites. The software is designed to be used in the context of all forms of intensitymodulated photon beam radiotherapy. The planning objectives themselves are intended to be TPSindependent: these are instead dependent on the degree of organ sparing possible given the beam modality and range of delivery techniques for plans in the database. To facilitate streamlined transmission of DICOM files and plan parameters Oncospace includes scripts using the treatment planning system's scripting language (for example, Pinnacle). #### INDICATIONS FOR USE V. Oncospace is used to configure and review radiotherapy treatment plans for a patient with malignant or benign disease in the prostate, head, and neck regions. It allows for set up of radiotherapy treatment protocols, association of a potential treatment plan with the protocol(s), submission of a dose prescription and achievable dosimetric goals to a treatment planning system, and review of the treatment plan. It is intended for use by qualified, trained radiation therapy professionals (such as medical physicists, oncologists, and dosimetrists). This device is for prescription use by order of a physician. {5}------------------------------------------------ Image /page/5/Picture/2 description: The image shows the logo for OncoSpace.

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE The Oncospace subject device is a software-only medical device that performs the same functions in the Oncospace predicate device. The following differences exist between the subject and predicate devices: - . The machine-learning algorithm has been generalized to allow training, modeling, and testing of dosimetric predictions for treatment target/organ-at-risk geometries and a head and neck model has been developed and added to the subject device. - The plan-matching method (a non-ML based method for dosimetric predictions) that was in place in the predicate device for head & neck, thoracic, and pancreas geometries has been removed. Note: The predicate device and subject device algorithms, and any future algorithm updates, are locked prior to clinical use. | Element | Subject | Predicate | Conclusion | |-----------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------| | Device Name | Oncospace | Oncospace | Identical | | 510(k) Owner | Oncospace, Inc. | Oncospace, Inc. | Identical | | 510(k) Number | K222803 | K202284 | | | Product Code | MUJ | MUJ | Identical | | Product Name | System, Planning, Radiation Therapy Treatment | System, Planning, Radiation Therapy Treatment | Identical | | Intended Use | Oncospace is used to configure and review radiotherapy treatment plans for a patient with malignant or benign disease in the prostate, head, and neck regions.

PERFORMANCE DATA The following verification and validation testing results (performance data) are provided in support of the substantial equivalence determination. Since this is a software-only medical device that does not control other devices the performance data do not include biocompatibility, electrical safety, electromagnetic compatibility, mechanical, acoustic, or animal testing. The verifications tests met all system requirements and acceptance criteria which address clinical, standard user interface, and cybersecurity requirements for the Oncospace device. The validation testing was performed using retrospective clinical data. The Oncospace device's purpose is to reduce the number of iterations necessary to achieve a clinically viable and deliverable radiation treatment plan. A validation trial was designed to demonstrate non-inferiority of mean organ-at-risk (OAR) dose sparing, an indicator of plan quality. This comparison of OAR sparing is only valid if target coverage is maintained, so this comparison was also made. Alongside these dosimetric comparisons, comparison of number of plan optimizations required to arrive at a clinically acceptable plan was carried out as a measure of any gain in planning efficiency. Sample sizes were determined by estimating variance in mean OAR dose so that the trial would have 80% power at a significance level of 0.05 and a non-inferiority margin of 10 Gy. A heterogenous retrospective set of traditionally planned radiation treatment plans for prostate (n=13, 10 different prescriptions) and head & neck (n=19, 12 different prescriptions) cancers was used for validation. Mean doses were compared for 7 OARs for prostate and 27 OARs for head & neck. - Prostate OARs for clinical performance testing: bladder, left and right femur, rectum, sigmoid colon, penile bulb, and bowel bag. For the prostate performance 1336 treatment plans were used for model development and internal validation (split 80/20), 13 plans were used for clinical performance testing. - Head and Neck OARs for clinical performance testing: brain, brainstem, spinal cord, left and right cranial nerve VIII (acoustic nerve) , left and right parotid glands , left and right eyes, left and right lens , left and right optic nerve, optic chiasm, oral cavity, soft palate, glottis, cricopharyngeus, esophagus, sublingual gland, mandible bone, left and right submandibular glands, left and right cochlea, thyroid gland, and pharyngeal constrictor muscle(s). For the head {9}------------------------------------------------ Image /page/9/Figure/2 description: The image shows the logo for OncoSpace.

The letters are white with a slight drop shadow, giving them a three-dimensional appearance. and neck performance 796 treatment plans were used for model development and internal validation (split 80/20). 19 plans were used for clinical performance testing. The Oncospace plan mean dose was statistically significantly lower for 2 OARs for prostate and 1 OAR for head & neck, and there were no statistically significant differences in mean dose for any of the remaining 5 OARs for prostate and 26 OARs for head & neck. The trial demonstrated non-inferiority of mean OAR dose to 5 Gy for prostate and 8 Gy for head & neck. There was no statistically significant difference in target coverage between clinical plans and plans created with use of the Oncospace system. Out of all the plans tested, no plan required more optimizations using Oncospace versus using traditional radiation treatment planning clinical workflow, and the average number of iterations was reduced by 77% using Oncospace. ## Conclusion Verification and validation (including performance testing) was conducted in accordance with FDA guidance recommendations to confirm the device design met all specifications, user needs, and was acceptable to qualified clinical users. Oncospace has passed all the tests and the provided testing results demonstrate safety and effectiveness as compared to the predicate device. It is therefore concluded that Oncospace is substantially equivalent to the predicate device. #### VIII. CONCLUSIONS The subject Oncospace device is similar in intended use and functionality to the predicate Oncospace device. Oncospace has the same technological characteristics and features as the previously cleared device and does not raise new questions of safety or efficacy compared to the predicate device as demonstrated through the system design and testing. Non-clinical and clinical verification, validation, and performance testing was conducted to confirm the device design met user needs and specifications and was acceptable to qualified clinical and non-clinical users. Oncospace has passed the verification and validation tests and provided clinical performance testing results with a library clinical dataset in order to demonstrate safety or effectiveness as compared to the predicate device. It is therefore concluded that the subject Oncospace device is substantially equivalent to the predicate Oncospace device.
