An Open-label, Phase I/II First in Human, Dose Escalation, Optimisation and Expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, Immunogenicity and Anti-tumour Activity of IPN01203 in Participants With Locally Advanced or Metastatic Solid Tumours Who Have Progressed on or After Immune Checkpoint Inhibitor Therapies

The purpose of this study is to determine the appropriate dosage, safety and
effectiveness of a new drug, IPN01203, in adults with advanced solid tumours.
Advanced solid tumours are cancers that can occur in various organs or tissues and have
spread from their original site to nearby tissues or other parts of the body.
There will be two parts to this study:
- Phase Ia: This part (called dose escalation) will find the dose range that shows
activity against the tumour and can be tolerated by participants by testing
different increasing doses of IPN01203.
- Phase Ib: This part (called dose optimisation) will assess the ability of the drug
to prevent, slow down, or stop the growth of tumours and how the body processes and
responds to the drug when given in "low dose" or "high dose." It will also further
explore the safety and tolerability.
An additional part (phase II) may be added to the study based on the results of phase Ia
and phase Ib.
Each part will consist of the following periods:
- A screening period (up to 28 days) to assess whether the participant can take part,
requiring at least 1 visit to the study centre.
- A treatment period where all eligible participants will receive IPN01203. Requires
approximately 15 visits for the first 2 months followed by 3 visits every month from
month 3 until unacceptable toxicity, disease progression, death, upon participant's
withdrawal of consent, investigator decision, or study termination by the sponsor,
whichever occurs first.
There will also be one visit at the end of treatment (EoT), 30 days after the last
administration of the study intervention or prior to the start of new anticancer
treatment, whichever is earlier. Additionally, there will be one visit (the safety
follow-up visit) 90 days after the last administration of study intervention or prior to
the start of new anticancer treatment, whichever is earlier.
In both parts of the study, participants will undergo blood sampling, urine collection,
physical examinations and clinical evaluations. They may continue some other medications,
but the details need to be recorded.
Each participant will be in this study until death or withdrawal from the study. IPN01203
will be provided to participants who tolerate it for as long as their disease does not
progress. Participants may withdraw consent to participate at any time.

Critères
Tous
- Participant must be ≥18 years of age, at the time of signing the informed consent.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
- Measurable disease per RECIST version 1.1 (at least one lesion that is measurable by
RECIST 1.1. Tumour lesions in a previously irradiated area are considered measurable
if progression has been demonstrated in such lesions after radiation) and documented
locally advanced or metastatic disease with CT and/or MRI.
- All acute, clinically significant (CS) treatment-related AEs from a prior therapy
resolved to Grade 1 or lower prior to study entry. Participants with chronic
toxicities such as Grade ≤2 neuropathy or alopecia can be included.
- Have a life expectancy for disease-related mortality, as evaluated by the
investigator.
- Male and female participants: Contraceptive use by men or women should be consistent
with local regulations regarding the methods of contraception for those
participating in clinical studies.
- Adequate haematologic and end organ function
- Participant is capable of giving signed informed consent as described in the
protocol.
Exclusion Criteria:
- Have untreated or active primary brain tumour, Central Nervous System (CNS)
metastases, leptomeningeal disease, or spinal cord compression.
- Experienced severe, life-threatening immune-mediated AEs, or infusion-related
reactions such as those that lead to permanent discontinuation while on treatment
with prior anticancer therapy such as immune checkpoint inhibitor therapy.
- History of known autoimmune disease
- History of stroke or significant cerebrovascular disease, encephalitis, meningitis,
organic brain disease (e,g., Parkinson's disease) or uncontrolled seizures in the
year prior to first dose of study drug.
- History of CS cardiac disease within 6 months prior to the initiation of study
intervention, including but not limited to unstable angina, acute myocardial
infarction, endoscopic or open-heart cardiac surgery, or heart failure classified as
New York Heart Association Grade 2 or higher. Additional exclusion criteria include:
1. Left ventricular ejection fraction <45%
2. QT interval corrected by Fridericia (QTcF) >470 ms (for women) and >450 ms (for
men) or CS arrhythmias.
- History of CS respiratory disease within 6 months prior to the initiation of study
intervention, including severe chronic obstructive pulmonary disease or asthma.
- Prior organ transplantation.
- Chronic or ongoing active infections within 4 weeks prior to Cycle1 Day1 (C1D1).
- Presence of hepatitis B surface antigen (HBsAg) [or hepatitis B core antibody
(HBcAb)] at screening or within 3 months prior to the first dose of study
intervention.
- Positive hepatitis C antibody test result at screening or within 3 months prior to
the first dose of study intervention.
- Participants with known history of HIV infection are excluded from the study unless
they meet the following criteria:
1. Stable Antiretroviral Therapy: Participants must be on a stable antiretroviral
therapy regimen for at least 4 weeks prior to enrolment.
2. CD4+ T cell Count: Participants must have a CD4+ T cell count of at least 200
cells/µL.
3. Viral Load: Participants must have an undetectable viral load (HIV RNA <50
copies/mL)
4. No Opportunistic Infections: Participants must not have had any opportunistic
infections or other human immunodeficiency virus (HIV)-related illness within
the past 6 months Note: HIV testing will be performed in any countries where it
is mandatory per local requirements.
- History of other malignancy within the last years.
- Significant concurrent, uncontrolled medical condition that would put participants
at unacceptable risk from study participation or preclude them from complying with
study procedures per investigator including, but not limited to renal, hepatic,
haematologic, gastrointestinal, endocrine, pulmonary, neurological, cerebral, or
psychiatric disease.
- Treatment with >10 mg per day of prednisone (or equivalent) or other immune
suppressive drugs within 7 days prior to the initiation of study drug. Exceptions

media. Steroids for topical, ophthalmic, inhaled, or nasal administration are
allowed.
- Concurrent participation in another therapeutic treatment study.
- Participants accommodated in an institution because of regulatory or legal order;
prisoners or participants who are legally institutionalised.
- For French participants only: participants are under court protection, not
