Description of intervention(s) / exposure
This study involves the use of two investigational compounds in patients with Extensive Stage Small Cell Lung Cancer (ES-SCLC) receiving maintenance phase maintenance treatment with immune
checkpoint inhibition therapy (standard of care treatment for ES-SLSC).

The first is an investigational imaging product 68Ga-SSO120 (68Ga-Satoreotide Trizoxetan) which will be used for two screening scans that will be taken pre- and post- treatment dosing with 177Lu-SSO110. The first scan using 68Ga-SSO120 will be at least 18 days prior to the planned first 177Lu-SSO110 dose. The second 68Ga-SSO120 scan will be performed at the end of treatment visit, which will be in the 6th week post the last dose of 177Lu-SSO110. All study participants (approx. 70) will undergo the screening with 68Ga-SSO120 as per the study eligibility screening criteria.

68Ga-Satoreotide Trizoxetan is an imaging agent for patients with somatostatin receptor 2 (SSR2) positive tumours. 68Ga-SSO120 will be administered intravenously 40-90 minutes before the PET/CT scan which will last approximately 15-30 minutes. To ensure adherence to the intervention a schedule of clinic and hospital visits will be given to the patients which encompasses their standard of care as well as their clinical trial treatment plan. To monitor patient adherence to the intervention, all patient visits (missed or attended) will be tracked in the site’s electronic medical record (EMR). All participants will receive up to 2 single doses of 68Ga-SSO120 (1 at screening and the other at the end of treatment visit), with 68Ga radioactivity of 150 MBq injected intravenously. The administered radiation dose will be 150 +/- 50 MBq, and the peptide mass dose up to 50 µg (prepared from a vial containing 50 µg of SSO120) infused by slow intravenous push and flushed with 10 mL of normal saline (0.9% sodium chloride solution), as appropriate.

The second is an interventional radiopharmaceutical product 177Lu-SSO110 (177Lu-satoreotide tetraxetan) which is anticipated to be administered to approximately 30 of the 70 participants screened with 68Ga-SSO120. Four cycles of 177Lu-SSO110 therapy are planned per protocol each as a single intravenous infusion, with the first administered within 7 weeks of the last induction cycle of immune checkpoint inhibition therapy. The initial administered radiation dose of 177Lu-SSO110 will be 3.7 GBq with a potential dose escalation up to 5.2 GBq or de-escalation to 2.3 GBq.

Dose escalation and de-escalation is for the purpose of establishing a Recommended Phase 2 Dose (RP2D). In this study the dose will be determined by the Safety Review Committee (SRC) who will be closely monitoring all patients for the incidence of dose limiting toxicities (DLTs) to determine the maximum tolerated dose of 177Lu-SSO110. Prior to participant dosing the SRC will review the incidence of any DLTs and will follow the protocol dose escalation guide (following a Bayesian Optimal Interval/BOIN) design) to provide the most appropriate dosing decision.

Subsequent 177Lu-SSO110 administrations will be given 6 to 9 weeks after the preceding 177Lu-SSO110 administration. In the case of resolving toxicity, an extension of up to 12 weeks after the preceding 177Lu-SSO110 administration may be granted with subsequent 177Lu-SSO110 administration(s) also delayed accordingly. For participants with clinical benefit at the end of the 4 cycles the Investigator may request that the patient is provided with up to three additional treatments provided they meet all the criteria in in Section 9.6.5. of the protocol.

177Lu-SSO110 will be administered by intravenous infusion over up to 30 minutes using the hospital’s standard practice for peptide receptor radionuclide therapy - the preferred method for administration is the gravity method. Infusion rate can be modified (up or down) per the Investigator’s judgement and may be temporarily halted or further slowed down if the participant does not tolerate the infusion. The overall infusion duration should not exceed 60 minutes. Concomitant renal protection via amino acid infusion will be administered starting 30 minutes prior to 177Lu-SSO110 infusion and continuing for 4 hours as per the joint International Atomic Energy Agency (IAEA), European Association of Nuclear Medicine (EANM), and Society of Nuclear Medicine and Molecular Imaging (SNMMI) practical guidance on PRRT in NETs (Section 9.1.5 of the protocol). The duration and method of administration will be recorded in the case report form (CRF). All administration of treatment on the study will be conducted in a hospital setting and therefore adherence to their intervention schedule will be monitored in the clinic’s EMR.

Treatment: Drugs
Comparator / control treatment
There is no comparator group for this study. Approximately 70 participants will undergo screening with 68Ga-SSO120. It is anticipated that approximately 30 of the 70 screened patients may respond positively to the 68Ga-SSO120 scan and therefore demonstrate SST2 expression. These patients will enter then be eligible to enter the treatment period and will be administered 177Lu-SSO110 therapy. Participants who demonstrate non-responsiveness to the 68Ga-SSO120 scan will be considered screen failures. Furthermore patients who do not undergo 68Ga-SSO120 will also be screen failures and therefore will not act as comparators.

One of the main objectives for this phase I study is to determine the Recommended Phase II Dose (RP2D) and therefore a comparator will not be required to be utilised.

Summary
Brief summary
This study aims to assess the safety and tolerability of two new drugs in patients with extensive stage small cell lung cancer (ES SCLC). The first drug (68Ga-SSO120/68Ga-Satoreotide Trizoxetan) is used as a tumour imaging agent for patients who have tumours with specific receptors, while the second drug (177Lu-SSO110) targets and damages cancer cells with these specific receptors.

Who is it for?
You may be eligible for this study if you are an adult aged 18 years or older, you have been diagnosed with extensive stage small cell lung cancer and if you are going to be receiving ICI maintenance therapy. All potential participants will be reviewed by the study investigators to ensure that they meet additional health criteria before enrolment.

Study details
All participants who choose to enrol in this study will undergo two screening scans using the new 68Ga-SSO120 imaging drug. The first scan will be to confirm eligibility to receive the 177Lu-SSO110 drug. If eligible, the first treatment dose with 177Lu-SSO110 will be scheduled at least 18 days after the 68Ga-SSO120 scan. The second scan with 68Ga-SSO120 will be taken at the end of treatment visit, which will be 6 weeks following the last dose of 177Lu-SSO110. For each scan, the 68Ga-SSO120 drug will be administered via an intravenous infusion 1 hour (40-90 minutes) before the PET/CT scan. The scans are anticipated to take 1-2 hours in total to complete. Participants who are confirmed to have somatostatin receptor 2 tumour cells based on the first screening scan will then be offered the opportunity to undergo treatment with the 177Lu-SSO110 drug. Participants who choose to enrol in the 177Lu-SSO110 arm of this study will have 177Lu-SSO110 administered via an intravenous infusion within 7 weeks after their last induction ICI therapy. Up to 3 additional 177Lu-SSO110 administration cycles will be given 6 to 9 weeks after the previous 177Lu-SSO110 administration. For participants with clinical benefit at the end of the 4 cycles the Investigator may request that the patient is provided with up to three additional treatments, which will be approved at the Sponsor’s discretion

It is hoped this research will demonstrate that each of the study drugs, 68Ga-SSO120 and 177Lu-SSO110 are safe and well tolerated by patients with extensive stage small cell lung cancer. If the results of this initial study are positive, a larger trial involving a greater number of patients with extensive stage small cell lung cancer may be undertaken to further determine the potential benefits of the new drugs.
