Description of intervention(s) / exposure

This research study involves a test drug called ReoCure alone or in combination with another drug called Keytruda® (pembrolizumab). ReoCure is a live Reovirus, commonly isolated from human digestive and respiratory tracts and has not been associated with symptoms or causing clinical disease. ReoCure which is under development by ViroCure, Inc. is a genetically unmanipulated naturally occurring, non-mutated strain of virus that preferentially infects and kills cancer cells, and hence being classified as oncolytic virus. As the infected cancer cells are destroyed by ReoCure (Reovirus that is able to kill cancer cells), they release new virus particles or virions to help destroy the remaining tumour.
The aim of this study is to assess the safety and find the correct dose of ReoCure alone and in combination with Pembrolizumab to patients with advanced malignant solid tumours. The study also aims to provide information on how the body handles ReoCure i.e. how it absorbs, distributes and eliminates ReoCure. Another aim of this study is to learn if ReoCure in combination with Pembrolizumab can help to control cancer better.
The study is divided in two parts, Phase 1a and Phase 1b. In Phase 1a - Dose Escalation, participants will receive either ReoCure alone or ReoCure in a combination with Pembrolizumab. Part 1a will take place in 2 parts: Part A ReoCure Monotherapy Dose Escalation and Part B ReoCure Combination therapy Dose Escalation. Phase 1b is the Dose Expansion part of the study.

Phase 1a Dose Escalation;
Part A (ReoCure Monotherapy Dose Escalation): There will be up to 3 cohorts (Cohorts 1, 2 and 3), with a minimum of 3 and a maximum of 18 participants until the recommended dose is determined or until the last dose level. If there are no changes seen in the participant's tumour after week 6, they may be eligible to receive Pembrolizumab (200mg once in every 3 weeks) alone or in combination with ReoCure at the same dose level as per the Cohort the participant is in. If the highest tolerable dose is not identified during the course of Part A study, the highest dose level (last dose level) will be the recommended dose of ReoCure monotherapy.
In Part A (ReoCure Monotherapy Dose Escalation), following dose levels are planned. The planned dose levels are as below:
• Cohort 1: 1.0×10^8 PFU ReoCure, 1 injection/cycle
• Cohort 2: 1.0×10^9 PFU ReoCure, 1 injection/cycle
• Cohort 3: 1.0×10^10 PFU ReoCure, 1 injection/cycle
Dose escalation will continue from the initial dose group (Cohort 1) within the range of 3 dose groups (Cohort 1-3) until the MTDReoCure is identified or until the last dose level.
The highest dose level at which MTDReoCure is not identified in Part A will be the RP2D of ReoCure monotherapy (RP2DReoCure).
After the tumour evaluation at week 6, patients in part A, who do not show any tumour response and patients who display a tumour progression (complete response [CR], partial response [PR] or stable disease [SD]), may receive 200 mg once every 3 weeks (Q3W) of Keytruda (Pembrolizumab) alone or in combination with ReoCure (at the dose level of relevant cohort) in subsequent cycles. This decision will be based upon mutual consultation between Investigator, Sponsor’s CMO and medical monitor, and will be taken based on the Investigator’s evaluation of clinical risks/benefits for the patient, on a case by case basis, and in the interest of the patient.

The duration of part A for each cohort is as follows: Minimum 21 days based on safety data and maximum number of cycles is based on response and safety outcome as per study stopping rules. This means patients who continue to derive the benefit from therapy can receive any amount of additional cycles with IP.

The frequency of ReoCure Administration: 1 cycle (C) consists of 21 days. Day (D) 22 of each cycle is D1 of the following cycle. Cohort 1, Cohort 2 and Cohort 3 of dose escalation phase: Intratumoral administration on Day (D) 1 of Cycle 1. The Investigator will determine whether a patient will continue treatment with the IP in the next cycle considering the tumour response and clinical condition of the patient after Cycle 1.
In the dose escalation cohort, a patient who experiences a DLT during the DLT observation period (Cycle 1, 3 weeks after first dose of IP) will temporarily discontinue the IP until recovery of the DLT. However, after resolution of the DLT, treatment may be resumed at the discretion of the Investigator with allowance of up to 2 weeks of delay in the next cycle. Dosing in Cycle 2 and Beyond: Patients with no clinical deterioration after Cycle 1 (21 days) will be allowed to be treated with subsequent cycles of ReoCure (and combination drug Keytruda [Pembrolizumab] where applicable) until any stopping rules are met.

ReoCure will be Intratumoral administration and pembrolizumab will be intravenous as per approved prescribing information

Part B (ReoCure Combination Therapy Dose Escalation):This part will test 2 dose levels of ReoCure in combination with a fixed dose of Pembrolizumab (200mg every 3 weeks) in 2 cohorts. There will be up to 2 cohorts (Cohorts 4 and 5) with a minimum of 2 and maximum of 12 participants, until the recommended dose is determined or until the last dose level. If the highest tolerable dose is not identified during the course of Part B study, the highest dose level (last dose level) will be the recommended dose of ReoCure combination therapy

2 dose levels are planned for 1a Part B on following lines
Here IP will be given in combination with fixed dose (200 mg Q3W) of Keytruda (Pembrolizumab).
Up to 2 cohorts (Cohorts 4 and 5) consisting of 1-6 patients per cohort will be recruited sequentially at 2 dose levels of ReoCure:
• at one dose level below maximum tolerated dose (MTD)ReoCure or at the Part A Cohort 2 dose (if MTDReoCure has not been determined) and
• at MTD ReoCure or at the Part A Cohort 3 dose (if MTD ReoCure has not been determined).

In phase 1a Part B;
• ReoCure will be given on Day (D) 1 of Cycle 1 .
• Fixed dose (200 mg Q3W every 3 weeks) of combination drug Keytruda (Pembrolizumab) will be provided on D8.
• Same dose will be administered for Cycle 2 and beyond.
ReoCure will be Intratumoral administration and pembrolizumab will be intravenous as per approved prescribing information
IP as monotherapy and in combination with Pembrolizumab will be administered in hospital setting.

Phase 1b Dose Expansion: This part will include a minimum of 10 and maximum of 15 participants (Cohort 6), to further test the safety of ReoCure in combination with a fixed dose of pembrolizumab (200 mg once in every 3 weeks) treated with the recommended dose selected from the Dose Escalation part of the study.

The MTD (or RP2D) will be assessed by dose limiting toxicity (DLT) evaluation in Phase 1a. MTD ReoCure is defined as the highest dose level of ReoCure alone at which less than or equal to 33% of patients.

Patients with no clinical deterioration after Cycle 1 (21 days) will be allowed to be treated with subsequent cycles of ReoCure alone or in combination with a a fixed dose of pembrolizumab (200mg once in every 3 weeks( until any stopping rules are met. This will occur at the Investigator’s discretion and with patient’s agreement. The selected dose and timing will be as per the most recently completed treatment period in which patients were enrolled - Since Intra-participant dose escalation is not allowed in any cohort. This is with reference to dosing patients in subsequent cycles of ReoCure with no clinical deterioration after Cycle 1 (21 days). The dose and timing in subsequent cycles will be based on previous cycles.
The decision to continue with dosing will be determined by the SRC after review of safety data.
An SRC comprising relevant site Investigator(s), the medical monitor and a Sponsor representative will oversee safety, cohort evaluation and dose escalation for the study. The SRC will be responsible for the safety of patients, and decisions relating to dose escalation and dose-expansion for the study.

The Stopping Rules are defined as per below:
The decision to continue with dosing will be determined by the SRC after review of safety data.
Administration of study drug in a dose cohort may be paused, and additional patients will not receive study drug, until a consultation has taken place between the Investigator, the medical monitor, and the ViroCure representative under the following circumstances:
• 2 or more patients experience a DLT at dose level 1 (1.0x10^8 PFU, 1 injection/cycle) in Phase 1a Part A;
• 2 or more patients experience a Grade 3 or higher clinical abnormality (except fever) (as defined in the NCI-CTCAE version 5.0) that is considered to be possibly or probably related to study drug;
• Any patient experiences an SAE that is considered to be possibly or probably related to study drug;
• Any patient experiences a Grade 3 or higher laboratory abnormality (as defined in the NCI-CTCAE version 5.0) that is considered to be possibly or probably related to study drug.
• An AE or group of AEs that singularly or in aggregate suggests to the Investigator or Sponsor that the study drug is poorly tolerated and further treatment per protocol may not be safe.

There is no maximum period specified for participants are followed for the purposes of this study. For cycle 2 onwards Patients with no clinical deterioration after Cycle 1 (21 days) will be allowed to be treated with subsequent cycles of ReoCure until any stopping rules are met. This will occur at the Investigator’s discretion and with patient’s agreement.
