Definitions
- the present invention relates to the use of kahalalide compounds in the treatment of cancer.
- the kahalalide compounds are peptides isolated from a Hawaiian herbivorous marine species of mollusc, Elysia rufescens. Kahalalides A-F are described in EP 610 078 and Hamman et al., J. Am. Chem. Soc, 1993, 115, 5825-5826.
- Kahalalide A-G are described in Hamann, M. et al., J. Org. Chem, 1996, 61, 6594-6600: "Kahalalides: bioactive peptides from a marine mollusk Elysia rufescens and its algal diet Bryopsis sp.”
- Kahalalide H and J are described in Scheuer P.J. et al., J. Nat. Prod. 1997, 60, 562-567: "Two acyclic kahalalides from the sacoglossan mollusk Elysia rufescens" .
- Kahalalide 0 is described in Scheuer P.J. et al., J. Nat. Prod. 2000, 63(1) 152-4 : A new depsipeptide from the sacoglossan mollusk Elysia ornata and the green alga Bryopsis species".
- Kan, Y. et al., J. Nat. Prod. 1999 62(8) 1169-72 "Kahalalide K: A new cyclic depsipeptide from the hawaiian green alga bryopsis species".
- Kahalalide F is the most promising because of its antitumoural activity.
- Kahalalide F now known to have the structure:
- Kahalalide F is a tridecapeptide with a ring shape side and a lateral side, containing a fatty acid group connected to the latter. Its activity against in vitro cell cultures of human lung carcinoma A-549 and human colon carcinoma HT-29 were reported in EP 610 078.
- WO 02 36145 describes pharmaceutical compositions containing kahalalide F and new uses of this compound in cancer therapy.
- the antitumoural compound Kahalalide F acts on cell lysosomes.
- kahalalide F exhibited low cardiac and skeletal muscle toxicities and also low myeolotoxicity.
- the main toxicities found were tubular nephrotoxicity and CNS (central nervous system) neurotoxicity, and hints of hepatotoxicity. Therefore the expected toxicities were renal and neurologic with a marked threshold.
- MTD central nervous system
- the present invention provides a method for treating a human patient afflicted with cancer, comprising administering to said patient a therapeutically effective amount of kahalalide compound, or a pharmaceutical composition thereof. More preferably the kahalalide compound is kahalalide F.
- the dose limiting toxicity in the treatment with a kahalalide compound is liver toxicity with grade 4 transaminase elevation. This toxicity is asymptomatic, manageable and reversible if the proper dosages and schedules are selected. Transaminases peak 4-5 hours after kahalalide infusion.
- the present invention provides a pharmaceutical composition containing a recommended dose of a kahalalide compound and a pharmaceutically acceptable carrier.
- the present invention provides a procedure for establishing the amount of a kahalalide compound to be recommended for dosing to patients, which procedure comprises administering the compound in a series of escalating doses to a cohort of humans, monitoring for transaminase elevation as the dose-limiting toxicity, determining a maximum tolerated dose, and establishing a recommended dose.
- the maximum tolerated dose is suitably set as one in which a proportion of the cohort encounter dose-limiting toxicity.
- the proportion is typically 2 out of 6.
- the recommended dose can then be established in accordance with familiar principles. Usually the recommended dose is the dose below the maximum tolerated dose, but sometimes rules are applied regarding the proportion of the cohort which encounter dose-limiting toxicity at the proposed recommended dose.
- the procedure for clinical trials enables a method of preparing a pharmaceutical composition containing a kahalalide compound, the method comprising carrying out the procedure to establish the recommended dose, and formulating the kahalalide compound with a pharmaceutically acceptable carrier to give a dosage form which contains the recommended dose of the kahalalide compound.
- the invention further provides for the use of kahalalide compounds in the preparation of a composition for the procedures and methods of this invention.

- the dose level is expanded to three patients with only 50% incremental increase in dosage in advancing to the next dose level.
- the dose level should be expanded up to six patients. This second cohort of 3 patients will be included consecutively. If the first or second patient develops dose limiting toxicities no further patients will be treated at this dose level, it will be defined as MTD and the accrual will begin at a lower dose level. If only one DLT occurs at this dose level another 3 patients will be included at the next dose level with an increase of 25% only.
- the maximum tolerated dose is defined as the dose at which at least 2 out of 3 or more than 3 patients experience DLT. However, it is possible that additional patients may experience DLT due to the timing of patient enrollment into that dose level. Once an MTD level is established, subsequent patients should be treated at the next lower dose level. Intermediate doses may be used in some instances and flexibility is an integral part of the protocol.

- Kahalalide F is one of a family of novel dehydroaminobutyric acid-containing peptides isolated from the Hawaiian herbivorous marine species of mollusk, Elysia rufescens. KF displays both in vitro and in vivo anti-tumour activity in various solid tumour models including breast, colon, non-small cell lung, and in particular prostate cancer. On the basis of its selectivity, KF is now further developed as a potential anticancer agent against androgen independent prostate tumours.
- OBJECTIVE In the present phase I clinical and pharmacokinetic (PK) study the toxicity profiles PK and anti-tumour activity of KF are investigated.
- KF is administered as an intravenous infusion over one hour, during five consecutive days every three weeks in patients with advanced or metastatic androgen refractory prostate cancer.
- a starting dose of 20 ⁇ g/m2/day was selected, which is equivalent to a total dose of 100 ⁇ g/m2.
- PK of KF were determined in plasma during the first course.
- Bioanalysis of KF was performed by LC- MS/MS. LDH, AF and especially PSA levels of each patient were also evaluated during the study to determine the activity of KF. RESULTS AND
- DISCUSSION At present 7 patients have been registered. Patients had a median age of 66 years (range 54-75). One patient per level was entered at
- PSA level 050% associated to clinical improvement (pain relief).
- Two additional patients experienced minor PSA reductions, one still ongoing after two cycles.
- the maximum tolerated dose has not been reached yet and the study is ongoing.
- KHF-A-001-00 Phase I Clinical and Pharmacokinetic study to determine the safety of kahalalide F administered as a daily x 5 over 1 hour Infusion every 21 days in patients with advanced or metastatic prostate cancer.
- a dose of 20 mcg/m2 was considered a safe starting dose on the basis of acute toxicity studies in animals.
- the trial was designed as an accelerated dose escalation (pharmacokinetically guided).
- Bilirubin 10 0 0 0 0
- liver toxicity was the most commonly seen as grade 4 transaminases elevation in the MTD (GOP, GPT levels). Patients also complain of puncture or prick on hands palms during the infusion.
- This trial was addressed to any solid tumours and was designed as a classical escalation.
- the starting dose was higher because we had some information from the first trial, and this allowed us to skip the first steps.
- One cycle in this trial means a week, so 4 cycles mean 1 month of treatment.
- the second dose level (400) was expanded because of two unrelated adverse events: grade 3 diarrhea and death due to gastrointestinal bleeding. This was also the reason why the next escalation was only 32.5% instead of 50%. No toxicities were reported in this level and the following escalation was 50% again.
- the DLT was identified at 1200 mcg/m2, and was grade 4 hypertransaminasemia non reversible by day 21.
- the time of onset was located at 5 hours after the infusion. This was not a scheduled determination and that was why the dose was descalated looking for previously unidentified grade 4 hypertransaminasemia.
- the 4th level was reexplored and this second time, grade 4 hypertransaminasemia was identified as DLT again at this dose level.
- KHF was supposed to be a non myelosuppressor agent. This prediction seems to have been confirmed in the clinical programme. Grade 1 -2 neutropenia was seen in 10% of patients. No grade 3-4 toxicities were reported.
- a grade 4 ALT is a marker of hepatocellular injury.
- HIPERSENSITIVITY Probably the most frequent toxicity observed with KHF is the palm hand prick referred by patients while the infusion. Sometimes this complaint was accompanied by other symptoms like erythema or pruritus in other locations.
- dose limiting toxicity for Kahalalide F was grade 4 hypertransaminasemia as in the previous example with a different schedule. It is an asymptomatic and reversible feature that appears 4-5 hours after the infusion of KHF. Hypersensitivity reactions with cutaneous features were commonly reported at highest levels.
