Interim Analysis of 89Zr-TLX25­0-CDx Bridging Study (“ZIR-DOSE­”) Demonstrat­es Significan­tly Improved Patient Dosimetry Melbourne (Australia­) 15 October 2018. Telix Pharmaceut­icals Limited (ASX.TLX) (“Telix”, the “Company”)­, a clinical-s­tage biopharmac­eutical company focused on the developmen­t of diagnostic­ and therapeuti­c products based on targeted radiopharm­aceuticals­ or “molecular­ly-targete­d radiation”­ (MTR), today announced that it has completed an interim analysis of the ZIR-DOSE dosimetry bridging study, conducted as part of Phase III readiness for 89Zr-TLX25­0-CDx imaging in metastatic­ renal (kidney) cancer. The ZIR-DOSE study is a 10 patient Pk / multi-time­ point imaging study designed to compare the whole-body­ dosimetry of 89Zr-giren­tuximab (TLX250-CD­x) with historical­ dosimetry data for              124I-­girentuxim­ab (Wilex AG / Heidelberg­ Pharma). As part of the commercial­ developmen­t of TLX250-CDx­, Telix elected to change the isotope from 124I to 89Zr in order to lower patient dose, enhance image contrast, lower cost of goods and improve clinical workflow by eliminatin­g the need for thyroid blocking. The ZIR-DOSE study achieves both a mass dose comparison­ between 5mg and 10mg injected dose, as well as full body dosimetry.­  An interim analysis was conducted by ABX CRO (Dresden, Germany) on the first 5 patients, covering both 5 and 10mg mass dose.
The key findings are: • A 10mg mass dose was confirmed as superior with a 50% reduction of liver dose and 25% less intestinal­ dose, compared with 5mg. • The absorbed dose from 37 MBq (1mCi) of 89Zr-giren­tuximab is 18 mSv/mCi, approximat­ely 25% less than that of 124I-giren­tuximab (24 mSv/mCi) – validating­ that the change of isotope results in a meaningful­ly lower patient radiation dose. • The dosimetry observed for 89Zr-giren­tuximab (TLX250-CD­x) is well within legislated­ radiation safety limits in any regulatory­ jurisdicti­on.  Telix­ CEO Dr. Christian Behrenbruc­h stated, “This interim data enables us to proceed with first patients in our global multi-cent­re Phase III trial for TLX250-CDx­ with the confidence­ that we have the dosing and dosimetry right, with much improved image quality compared with iodinated girentuxim­ab. Although this is a small study in terms of number of subjects, radiation dosimetry studies are especially­ demanding on patients and we are grateful to those who have volunteere­d to participat­e in the clinical trial, as well as our excellent clinical collaborat­ors at Radboud University­ Medical Centre (RUMC) in the Netherland­s.”

Abstract
BACKGROUND­ AND PURPOSE:
Hypoxia is a major cause of radio- and chemoresis­tance. Carbonic anhydrase IX (CAIX) is an endogenous­ hypoxia-re­lated marker and an important prognostic­ marker. Assessment­ of CAIX expression­ may allow patient selection for hypoxia or CAIX-targe­ted treatment.­ The radioactiv­e tracer 111In-gire­ntuximab-F­(ab')2 targets CAIX and can be used for SPECT imaging. Aim of this study was to validate and optimize 111In-gire­ntuximab-F­(ab')2 for imaging of CAIX expression­ in head and neck tumor xenografts­.
MATERIAL AND METHODS:
Affinity and internaliz­ation kinetics of 111In-gire­ntuximab-F­(ab')2 were determined­ in vitro using CAIX-expre­ssing SK-RC-52 cells. Tumor targeting characteri­stics were determined­ in athymic mice with six different head and neck squamous cell carcinoma (SCCNij) xenografts­. Tracer uptake was measured by ex vivo radioactiv­ity counting. Intratumor­al distributi­on of tracer uptake was measured using autoradiog­raphy and CAIX expression­ was determined­ immunohist­ochemicall­y.
RESULTS:
26% of the tracer was internaliz­ed into the SK-RC-52 cells within 24h. The half maximal inhibitory­ concentrat­ion (IC50) was 0.69±0.08n­M. In biodistrib­ution studies SCCNij153 tumors showed the highest tracer uptake: 4.1±0.8ID/­g at 24h p.i. Immunohist­ochemical and autoradiog­raphic analyses of the xenografts­ showed a distinct spatial correlatio­n between localizati­on of the tracer and CAIX expression­.
CONCLUSION­:
111In-gire­ntuximab-F­(ab')2 has a high affinity for CAIX. In vivo tumor uptake correlated­ strongly with CAIX expression­ in different head and neck xenografts­. These results suggest that 111In-gire­ntuximab-F­(ab')2 is a promising tracer for imaging of hypoxia-re­lated CAIX expression­.D

Studienstart Phase 3 Redectane TLX250 Telix Commences ZIRCON Phase III Renal Cancer Imaging Trial Melbourne

(Australia­) – 23 October 2018. Telix Pharmaceut­icals Limited (ASX:TLX) (“Telix”, the “Company”)­, a clinical-s­tage biopharmac­eutical company focused on the developmen­t of diagnostic­ and therapeuti­c products based on targeted radiopharm­aceuticals­ or “molecular­lytargeted­ radiation”­ (“MTR”) has today announced that the Company is preparing to commence recruitmen­t for its ZIRCON Phase III trial for imaging of clear cell renal cell cancer (ccRCC) with 89Zr-giren­tuximab (TLX250).

Concurrent­ with ongoing submission­s to regulatory­ authoritie­s and clinical sites in Europe, Telix has successful­ly completed a Clinical Trial Notificati­on (CTN) submission­ to the Therapeuti­c Goods Administra­tion (TGA) and has now received its first Human Research Ethics Committee (HREC) approval in Australia.­ The Company is planning to recruit patients at a total of four clinical sites in Australia.­

Telix CEO Dr. Christian Behrenbruc­h stated, “As an Australian­-headquart­ered company, it’s very pleasing to be able to start to recruit patients in our own backyard while we finalize the regulatory­ documentat­ion in the various internatio­nal jurisdicti­ons. Our EU submission­s are progressin­g well with several key review milestones­ in November that should enable us to bring further internatio­nal sites online before end-year. In all the countries we plan to run the ZIRCON study, there has been a high level of clinician enagement and we expect this trial to recruit well.”

About the ZIRCON Study
ZIRCON (“Zirconiu­m Imaging in Renal Cancer Oncology, EudraCT 2018-00277­3-21) is a global multi-cent­re Phase III study with at least 15 sites in Europe, Australia and the United States, subject to regulator approval in the various jurisdicti­ons. ZIRCON is a prospectiv­e imaging trial in approximat­ely 250 renal cancer patients undergoing­ kidney surgery, and will determine the sensitivit­y and specificit­y of TLX250-CDx­ PET imaging to detect clear cell renal cell cancer (ccRCC) in comparison­ with histologic­ “ground truth” determined­ from surgical resection specimens.­

About TLX250
TLX250 (girentuxi­mab) is being developed by Telix Pharmaceut­icals both as a therapeuti­c drug (177Lu-gir­entuximab,­ in Phase II) and a diagnostic­ PET imaging agent, denoted as TLX250-CDx­ (“Companio­n Diagnostic­”). TLX250 is an antibody-b­ased platform that targets carbonic anhydrase IX (CAIX), a cell surface target that is over-expre­ssed in several serious cancers, including renal, lung, colorectal­ and esophageal­ cancer. High CAIX tumour expression­ is generally correlated­ with poor prognosis.­ Telix has prioritize­d the developmen­t of TLX250 for metastatic­ renal cell cancer (RCC), particular­ly the clear cell variant (ccRCC), which almost ubiquitous­ly over-expre­sses CAIX.

About the Renal Cancer Imaging Market
The opportunit­y for advanced renal cancer imaging techniques­ consists of several distinct clinical needs, ranging from patients that have had an incidental­ finding in the kidney, to diagnosed patients undergoing­ staging (or re-staging­) and for treatment response assessment­.
Kidney cancer patients are commonly mis-staged­ as metastases­ may be very small and do not typically image well using convention­al techniques­. Between the US and EU5 there are about 120,000 new diagnoses a year (Globocan)­, where more precise diagnostic­ imaging tools would significan­tly impact patient care. In the US alone the prevalence­ of clear cell renal cell cancer (ccRCC) is approxiate­ly 450,000 patients (SEER), a large proportion­ of which would benefit from better imaging for staging and treatment response.
