Brief Summary:
This study aims to evaluate the effect of food on the pharmacokinetics of ModraDoc006 in combination with ritonavir, in an open-label, cross-over design. Patients will be randomized into two treatment groups receiving ModraDoc006/r week 1 under fasting and week 2 under fed condition, or vice versa.

Condition or disease Intervention/treatment Phase
Solid Tumor, Adult Drug: ModraDoc006/r Phase 1

Detailed Description:

In this study the effect of food on the plasma exposure of ModraDoc006/ritonavir will be assessed in an open-label, cross-over design. Patients will receive ModraDoc006/ritonavir at the dose of 30 mg ModraDoc006 with 100 mg ritonavir.

Patients will be randomized 1:1 into two treatment groups (in total 16 evaluable patients are needed):

  • Group A: will receive ModraDoc006/ritonavir under fasting conditions the first week and in a fed condition the second week of treatment.
  • Group B: will receive ModraDoc006/ritonavir under fed condition the first week and under fasted condition the second week of treatment.

The department of pharmacy of The Netherlands Cancer Institute - Antoni van Leeuwenhoek Hospital has developed a solid oral dosage form of docetaxel, ModraDoc006 10 mg tablets. This formulation has been investigated in two phase I clinical studies in combination with the CYP3A4 inhibitor ritonavir, according to a weekly once-daily (QD) or bi-daily (BID) schedule, respectively. Maximum Tolerated Dose (MTD) and pharmacokinetics of both regimes have been determined and further clinical testing is being planned, in particular of the weekly bi-daily regime.

The aim of the current study is to evaluate the effect of food on the pharmacokinetics of ModraDoc006 in combination with ritonavir. For the ritonavir tablet formulation used in this trial a food-effect on the bio-availability has been found in two prior studies. In these trials the plasma concentrations were lower when ritonavir was given after a moderate or high-fat meal. Plasma concentrations and T-lag were dependent on the type/amount of food administered. Concentrations were lower and T-lag longer when a high-fat meal was administered as compared to a moderate fat meal.

Randomization will be performed centrally at the Biometrics Department of the Netherlands Cancer Institute using a minimization technique as implemented in TENALEA©.

Pharmacokinetics will be performed in week 1 and 2 for up to 48 hours after study drug administration (see Pharmacokinetics paragraph for exact time points). Patients will receive a high-fat meal on the morning of the day of fed condition pharmacokinetics, half an hour prior to intake of ModraDoc006/ritonavir.

After week 2, the N15FED study will be completed and patients can be enrolled in the roll over study N17DEX to continue their treatment with ModraDoc006/r (at the dose of BID 30/20 mg ModraDoc006 in combination with BID 100 mg ritonavir) in their best interest and to assess the long-term safety of this treatment.

ModraDoc006/r will be administered in fasting condition week 1 and in fed condition week 2
Drug: ModraDoc006/r
Treatment with weekly ModraDoc006 (oral docetaxel) 10mg tablets in combination with ritonavir 100mg tablets in fed or fasting condition
Other Name: oral docetaxel formulation

Experimental: arm B Fed-Fasting condition
ModraDoc006/r will be administered in fed condition week 1 and in fasting condition week 2
Drug: ModraDoc006/r
Treatment with weekly ModraDoc006 (oral docetaxel) 10mg tablets in combination with ritonavir 100mg tablets in fed or fasting condition
Other Name: oral docetaxel formulation




Primary Outcome Measures :
  1. The AUC of docetaxel (area under the curve) [ Time Frame: Pharmacokinetic sampling during 2 weeks, 0-48 hours after administration (i.e. the 2 treatment cycles) ]
    The AUC of docetaxel given as bi-daily ModraDoc006 10 mg tablets in combination with ritonavir after administration in a high fed and fasting condition

  2. The cMax (peak concentration) of docetaxel [ Time Frame: Pharmacokinetic sampling during 2 weeks, 0-48 hours after administration (i.e. the 2 treatment cycles) ]
    The cMax (peak concentration) of docetaxel given as bi-daily ModraDoc006 10 mg tablets in combination with ritonavir after administration in a high fed and fasting condition


Secondary Outcome Measures :
  1. The hematological and non-hematological toxicity profile of oral docetaxel in combination with ritonavir [ Time Frame: Safety and tolerance will be evaluated during the complete study treatment untill 28 days after the last intake, using the CTCAEv4.03 grading system ]
    The number of CTCAE v.4.03 grade 3-4 toxicities during treatment with ModraDoc006/r

  2. The effect of functional genetic polymorphisms on the pharmacokinetics of oral docetaxel and ritonavir (to understand the mechanism of the drug-drug interaction more thoroughly) [ Time Frame: Sampling at baseline, the analyses will be performed retrospectively ]
    Pharmacogenetic analyses will be performed for polymorphisms in drug metabolizing enzymes (e.g., but not limited to genes encoding for P-glycoprotein (ABCB1/MDR1), Multidrug resistance protein 2 (ABCC2/MRP2), Organic anion-transporting polypeptides 1B3 (OATP1B3), Cytochrome P450 (CYP) 3A4 and CYP3A5)
