A Bioequivalence Study of Docetaxel Injection in Patients With Solid Tumours

Inclusion Criteria:

Patients meeting all of the following criteria will be considered for enrollment in the study.

1. Patients of either gender, ≥18 years of age.
2. Willing and able to provide signed and dated informed consent prior to any study-related procedures and willing and able to comply with all study procedures.
3. Histologically or cytologically confirmed advanced solid tumors who are scheduled to receive treatment with single-agent docetaxel, in the dose of 75 mg/m2 or those whose are already receiving single-agent docetaxel (taxotere® or an approved generic drug of taxotere®), in the dose of 75 mg/m2 and are scheduled to two more cycles, in the same dose, as per the actual treatment plan. Note: Metastatic castration-resistant prostate cancer will not be considered for the study as the patients are required to receive prednisone along with docetaxel and the regime of dexamethasone (CYP 3A4 inducer is different from that in other indications)
4. ECOG performance status 0 or 1 and Life expectancy ≥3 months (as per the Investigator's discretion).
5. Adequate Hematopoietic, Renal and Liver function defined as the following:

   Bone marrow function :ANC ≥1500/mm3, Platelet count ≥100,000/mm3, Haemoglobin \> 9.0 g/dl Hepatic function:ALT/AST ≤ 1.5 × ULN, Alkaline phosphatase ≤ 2.5 × ULN ,Total Bilirubin ≤ ULN Renal function:Serum creatinine ≤1.5 x ULN
6. Prothrombin time, international normalized ratio or activated partial thromboplastin time \<1.5 × ULN; Use of full dose anticoagulants is permitted. These laboratories should be maintained within the therapeutic range and closely monitored by the Investigator.
7. Recovery, to Grade 0-1 (as per CTCAE 5.04 criteria), from adverse events related to prior anticancer therapy except alopecia and endocrinopathies controlled with hormone replacement therapy.
8. Prior chemotherapy (except ongoing taxotere or an approved generic of taxotere, in which last dose must have been received at least 21 days prior to cycle 1 of the study), immunotherapy and radiation therapy must be completed at least 30 days prior to randomization (42 days for mitomycin C or nitrosoureas). Completion of palliative radiotherapy to a single disease site must be completed at least 14 days prior to randomization.
9. In case of female patient, the serum pregnancy test at screening visit and urine pregnancy test at baseline must be negative.
10. Sexually active women, unless surgically sterile (at least 6 months prior to Study drug administration) or postmenopausal for at least 12 consecutive months, must use an effective method of avoiding pregnancy (including oral, transdermal, or implanted contraceptives \[any hormonal method in conjunction with a secondary method\], intrauterine device, female condom with spermicide, diaphragm with spermicide, absolute sexual abstinence, use of condom with spermicide by sexual partner or sterile \[at least 6 months prior to Study drug administration\] sexual partner) for at least 1 month prior to study drug administration, during study and up to 6 month after the last dose of study drug. Cessation of birth control after this point should be discussed with a responsible physician.
11. In case of male patients: either partner or patient must use an effective method of avoiding pregnancy for at least 1 month prior to study drug administration, during study and up to 3 month after the last dose of study drug. Cessation of birth control after this point should be discussed with a responsible physician.

Exclusion Criteria:

Patients will be excluded from the study, if they meet any of the following criteria:

1. Hypersensitivity or idiosyncratic reaction to docetaxel, its excipients, and/or related substances including polysorbate 80, paclitaxel, alcohol, dexamethasone and Antiemetic (Granisetron or Ondansetron).
2. Severe cardiovascular disease, including CVA, TIA, myocardial infarction, or unstable angina within 6 months of study entry; NYHA class III or IV heart failure within 6 months of study entry; uncontrolled arrhythmia within 6 months of study entry.
3. Average corrected QT (QTc) interval by Frederica's formula (QTcF) on triplicate ECGs at screening \> 470 msec (females) or \> 450 msec (males); or on concomitant medications that would prolong the QT interval; or have family history of long QT syndrome.
4. Patients with an active infection (e.g. tuberculosis, sepsis and opportunistic infections).
5. Patients with severe pleural effusion (volume involving \> 40% of the hemithorax on CT scan chest) or gross ascites (\>800ml of ascitic fluid)3,4.
6. Peripheral neuropathy ≥grade 2 (as per CTCAE 5.04 criteria).
7. A positive hepatitis screen including hepatitis B surface antigen and HCV antibodies.
8. Patients with HIV infection.
9. Patients with known brain metastasis or those showing neurologic symptoms due to brain metastasis.
10. Recent or clinically significant history of drug or alcohol abuse.
11. Patients require concomitant treatment with potent Cytochrome P450 3A4 inhibitors, inducers or substrates.
12. Use of any Cytochrome P450 3A4 inducers, inhibitors, or substrates that may alter docetaxel metabolism (e.g. dronedarone, epirubicin, sorafenib, CNS depressants) within 14 days before randomization.
13. Major surgery within 4 weeks prior to study entry; minor surgery within 2 weeks prior to study entry.
14. Patients found positive on urine scan for drugs of abuse and/or breath test for alcohol consumption at screening or baseline. Note: Benzodiazepines and /or opioids given in therapeutic doses under the observation of physician for management of insomnia / anxiety / pain, etc., will be allowed, provided that there is no drug-drug interaction with the study drug and an approval from the Veeda medical monitor is taken.
15. The receipt of an investigational medicinal product or participation in other drug research study within a period of 30 days (or 5 half-lives, whichever is longer) prior to the first dose of investigational medicinal product for the current study.
16. Pregnant or Breast feeding female.
17. Donation of blood (1 unit or 350 ml) within 90 days prior to receiving the first dose of investigational medicinal product for the current study.
18. Abnormal baseline laboratory / physical findings considered to be clinical significant by the investigator.
19. Patients with any significant history of non-compliance or inability to reliably grant informed consent.
